    Field of the invention
    The invention relates to a method for constructing an installation for waste water treatment and such an installation. Such an installation serves primarily for cleaning waste water.
    State of the art
    Compared to the conventional installation construction method, the modular installation systems can be realized considerably faster and with less effort. They are easier to adapt to changing operating conditions of the customers (for example, modules are added in the case of a necessary installation extension). If necessary, they can also be relocated to other locations. A module module replaces an industrial building of, for example, concrete and steel.
    Such modular systems are known in principle from the prior art. For example, publication EP 2 049 398 B1 discloses a modular passenger terminal, predominantly for use at airports, as well as a method for constructing it. However, the system disclosed there is only to a limited extent suitable for a waste water treatment installation.
    Target
    It is the object of the invention to provide a modular installation for waste water treatment and a method for constructing it.
    Solution
    This object is achieved by the inventions with the features of the independent claims. Advantageous further elaborations of the invention are defined in the subclaims. The text of all conclusions is therefore deemed to be included in the content of this description.
    Individual process steps are described in more detail below. The steps do not necessarily have to be carried out in the order indicated and the method to be described can also comprise additional, non-named steps.
    To achieve the goal, a method for constructing a waste water treatment plant is proposed with the following steps: a) providing several room modules at a prefabrication site. The space modules can be transported and assembled there by conventional transport vehicles for containers on land, water and in the air to the prefabrication site or a predetermined place of installation. b) connecting the room modules in such a way that it is required in the wastewater treatment plant to be constructed. (c) the incorporation of technical devices necessary for waste water treatment into the room modules at the prefabrication site. d) connecting the technical installations at the prefabrication site, such as is required in the waste water treatment plant to be constructed. e) testing the correct functioning of the connected room modules or technical devices at least as part of an installation for waste water treatment. f) separating the space modules and configuration thereof for transport with the technical devices remaining in the space modules. g) transporting the room modules with the technical devices contained therein to a place of installation. h) preparing required connections at the installation site. i) the installation, connection and connection of the room modules at the prepared place of installation.
    The room modules typically correspond to steel containers with self-supporting steel frame construction with container corner fittings according to ISO 1161. The containers typically have a width of 2.4 m - 3.2 m, a length of 3 - 13 m and a maximum height of 3 m.
    In order to be able to transport the space modules with the worldwide transport and transfer devices for containers, sea modules are preferably used for sea transport which, with respect to the outer dimensions, correspond to the standards for containers, preferably ISO 668. Special container sizes, on the other hand, will preferably be transported by land. This facilitates the transport from the prefabrication site to the place of installation as well as the assembly there and makes this possible with less costs.
    Because the technical devices required for waste water treatment are installed in the room modules at the prefabrication site, it is no longer necessary at the place of installation to carry out labor-intensive assembly steps. The separately prefabricated modules of the modular installation system need only be set up and assembled there. To this end, adequate interfaces have been formed between the room modules and / or the technical devices installed therein.
    These are already used at the prefabrication site to connect the room modules or the built-in technical devices to each other, and in this way, as it is also planned for later installation of the installation at the prefabrication site. This makes it possible to test at least a part of the installation that is assembled from the prefabricated room modules immediately after prefabrication. As a result, the quality of the entire installation is increased, as problems that arise can be noticed and resolved directly in the context of the prefabrication of the room modules. The total installation is preferably tested.
    Typically, in an installation from several containers arranged side by side or on top of each other, the walls between the holders are removed and only the outer walls are maintained.
    When configuring the room modules for transport, for example, the built-in technical devices are protected, room modules without side walls are stabilized with additional supporting beams (which can also be done at an earlier time), and missing side walls are replaced by provisional, possibly reusable side walls which protect the interior spaces and the technical devices built into the room module against weather influences, damage and / or theft.
    This method makes it possible to construct an installation for waste water treatment in a very flexible and inexpensive manner, and also for use in places where a conventional construction of such an installation, for example due to poor accessibility, would only be possible with great efforts.
    In an advantageous further elaboration, the space modules provided are coated by means of cathodic dip lacquers (KTL) before step b), but after the installation of fastening devices for the technical devices for waste water treatment. As a result, optimum corrosion protection can be obtained both inside and outside. This is of particular advantage for wastewater treatment plants, since splashing water, leaks, increased humidity and influences of chemicals can occur, which particularly favor corrosion. Prior to the cathodic immersion varnishes, the room module is prepared for the later installation of the technical installation (for example, holes for the floor drain element are inserted, fixing points or welding plates for installation technology are applied by welding, etc.). The cathodic immersion varnishes then take place in such a way that it can be guaranteed that all relevant structural elements are covered or the cover must not be damaged during the installation of the technical installation.
    The object is furthermore achieved by an installation for waste water treatment a) with a plurality of room modules; b) which are transported and assembled there by means of conventional container transport vehicles on land, water and in the air to a predetermined place of installation; (c) the technical devices required for waste water treatment have been introduced into the space modules; and d) wherein the room modules including the built-in technical devices can be prefabricated.
    The space modules are preferably containers with self-supporting steel construction. Thereby it is achieved that the space modules can be transported with the worldwide transport and transfer devices for containers, which in the first place facilitates the transport from the prefabrication site to the place of installation and the installation of the installation there and makes it possible with less costs.
    It is furthermore advantageous if the roof of each room module is inclined at least 1% in the longitudinal direction. This prevents large amounts of rainwater from collecting on the roof. The water can flow away at the "short" edge of the room module.
    In an advantageous further elaboration of the invention, all space modules are coated with cathodic dip paints (KTL).
    Moreover, it is advantageous if each room module has a container as a bottom that can collect outflowing liquids. The tray extends upwards at least 3 cm, preferably at least 10 cm, at the walls of the room module. Furthermore, the container has an opening for a bottom drain element.
    In addition, the bottom of the room module is often provided with welded-on support plates. The technical devices are thereby screwed to the support plates.
    The tray is preferably designed as a ribbed sheet steel. However, versions in other materials are also conceivable, for example plastic.
    Because the trough at the side walls is led a few centimeters upwards, the side walls of the room modules are protected against flowing liquids. Any water present in the room modules (for example due to installation cleaning or leakage) can be drained away by floor drain elements arranged at the openings.
    The welded-on support plates enable installation technology to be protected during transport or operation by being screwed to the support plates.
    To this end, the support plates are provided before the cathodic immersion paints of the room module, such that after the cathodic immersion paints have taken place, the support plates are also protected against corrosion.
    In a further additional advantageous further elaboration, the bottom drain element has the following features: a) the opening of the tray for the bottom drain element is larger than the diameter of the dewatering pipe; b) the opening is closed by a first plastic plate which closely encloses the dewatering pipe; c) the end of the dewatering pipe is closed off by a second plastic plate, which encloses the actual bottom drain element closely; d) wherein the first and the second plastic plate are cut to size when connecting the bottom drain element to the drainage pipe; and e) the spaces are filled with sealing compound, for example cement.
    This ensures that the opening in the floor of the room module, the floor drain element and the drainage pipe present at the location of installation can be connected to each other without any problems, despite any inaccuracies occurring.
    In a further advantageous elaboration, room modules or subareas of room modules, which are used as electrical switching space, are isolated atmospherically from the other room modules and / or are air-conditioned separately from the other room modules. They also have a fan, which transports air from the area or room module used as an electrical switching room to an adjacent area / module. This ensures that no (moist and / or corrosion-promoting) air from the other room modules can end up in the module used as an electrical switch room. Instead, outside air automatically flows into the electrical switch room. An additional advantage of this air conduction is that the air, which is transported to the module adjoining the electrical switching room, is automatically pre-heated (on the basis of the outlet heat from the switch boxes). This minimizes the risk of frost in the other room modules to which the air is transported
    It is furthermore advantageous if chemicals necessary for the operation of the installation are made available in chemical containers, wherein the chemical containers are placed on sump trays, dosing pumps are mounted above the chemical containers on the ceiling of the relevant room module and the chemical containers and dosing pumps are mounted through a curtain, transparent plastic slats, are separated from the other inner space of the respective room module. As a result, the required installation space can be reduced in comparison with traditional installations, because in the latter, the dosing pumps are usually mounted on wall holders or in separate dosing cabinets. Thus, in the case of the present invention, the chemical containers with the dosing pumps can advantageously be built into the room module, and furthermore the other interior space is protected against splashing, for example as a result of leaks.
    Furthermore, it is advantageous if an expanding sealing strip as well as a joint seal are provided between immediately adjacent room modules between the adjacent edges of room modules. As a result, irregularities with regard to the shape of the room modules or even small inaccuracies in their arrangement can be sealed.
    Additional details and features follow from the following description of preferred exemplary embodiments in combination with the subclaims. The relevant features can be realized independently or together in combination with each other. The possibilities for achieving the goal are not limited to the exemplary embodiments. For example, ranges always include all - not mentioned - intermediate values and all conceivable partial intervals.
    The exemplary embodiments are shown schematically in the figures. Identical reference numbers in the individual figures denote identical or functionally identical elements or elements corresponding to each other with respect to their functions. In detail shows:

    FIG. 8 is a schematic top view (from above) of a room module with chemical containers and dosing pumps
    An installation for waste water treatment according to the invention will be described in more detail by way of example with reference to the figures.
    As shown in FIG. 1, the installation consists of several prefabricated room modules 100 which, with respect to their outer dimensions and fastening devices, are transported by means of conventional transport vehicles for standardized containers to a predetermined place of installation and assembled there. FIG. 1 also shows a few tanks 20 that supplement the modular installation.
    As Fig. 2 shows, technical devices 50 required for waste water treatment are built into the room modules 100, 110.
    FIG. 3 shows a schematic cross-sectional view of the shape of the bottom of two adjoining room modules 100, 110. This bottom is designed above an insulation 120 as a ribbed steel sheet, the ribbed steel sheet being guided a few centimeters upwards at the side walls, so that the bottom forms a container 130 and the side walls 120, 140, 150 are protected against flowing liquids. Any water present in the room module (for example due to installation cleaning, leakage) is discharged from this trough 130 by adequate messenger drain elements. For this purpose, an opening 160 is provided in the bottom of each room module. In preparation, pipes are also laid in the ground at the place of installation to drain the water from the room modules.
    A special sealing strip 170 is provided between abutting room modules 100, 110 and expanding up to 30 mm. This takes place in the roof and the bottom, possibly also on the side walls. The task is to compensate for possible gaps caused by unevenness in the frame of the room modules or by inaccuracies in their positioning. The joint is then sealed, for example with a Sikaflex seal 180.
    For the later protection of the technical installation during transport or operation, support plates are welded to the ground in the room modules. Such a support plate 200 is shown in FIG. The technical installation can then be screwed on with the support plates.
    Since the interior space of the modules is used for waste water treatment and the room modules are exposed to weather influences, the corrosion protection of the modules is very important. Corrosive influences can be caused in particular by increased humidity in the interior, the discharge of (waste) water through splash water or leaks, the use or storage of chemicals in the modules or also due to weather influences at the installation location. For optimum corrosion protection (both inside and outside), the entire room module (steel frame, bottom, walls, roof, etc.) has a KTL coating (cathodic dip paints), preferably with a thickness of 30-60 µm. Prior to the cathodic immersion paints, the room module is prepared for the later installation of the technical installation (for example, holes for the floor drain element are inserted, fixing points or supporting plates for the technical installation are applied by welding, etc.). The cathodic immersion varnishes then take place in such a way that it can be guaranteed that all relevant structural elements, including, for example, the supporting plates, have come into contact with the covering and that the covering must not be damaged during installation of installation technology.
    Any water present in the room module (for example due to installation cleaning or leakage) is drained off by adequate soil drainage elements. For this purpose, a bottom drain element, as shown in Fig. 5, is provided in the bottom of each room module. In preparation, pipes are laid in the ground at the installation site to drain the water from the room modules. The pipe ends 300 come exactly at those places from the bottom where the bottom drain elements of the room modules are later placed.
    It is now a challenge to fit the room modules properly on top of the pipes installed at the installation site to install the water drainage in the room module. To this end, the opening 160 for the dewatering pipe in the room module is selected to be larger than the diameter 310 of the pipe laid at the installation location. The room module is now placed on top of the pipe laid at the installation location. As the lower seal, a first plastic plate 320 with the larger diameter 330 is adapted such that it closely connects to the pipe 300. A second plastic plate 340 is mounted on the pipe end 300, into which the actual bottom discharge element 350 is fitted. The bottom drain element has a closing plate, in which the water drain is made possible via perforation or openings made in another way. The space between the bottom drain element and the bottom 360 of the room module is sealed with a sealing mass 370 (e.g., non-shrinking cement).
    Reference is made below to Fig. 6. The indoor air of the room module can have a corrosive effect, for example due to increased air humidity or the use of chemicals.
    In order to protect control cabinets 400 or their electrical, electronic and mechanical components against corrosion, the room module 410, which is used as an electrical switch room, is encapsulated 420, that is, atmospherically separated from the other room modules. In order to ensure that no air from the other room modules can end up in the module 410 used as an electrical switch room, the area 430 adjacent to the electrical switch room is supplied by means of a fan 440 with the air 450 from the module 410 used as an electrical switch room. provide air. As a result, outside air 460 automatically flows into the electrical switching space 410. An additional advantage of this air conduction is that the air 450, which is sucked into the area 430 adjacent to the electrical switching space, is preheated by the waste heat from the switch boxes 400. This minimizes the risk of frost in the other room modules into which the air is drawn. For protection against overheating, an air handling device 470 is installed in the electrical switch room, which can lower the temperature in the room.
    To effectively avoid a corrosive atmosphere in the room module, a multiple air exchange per hour is required. This can be achieved by arranging those fans, which are required for technical installations for waste water treatment (for example, for air-conditioning a basin for the aerobic biological waste water treatment) in the room module, such that the room air from the room modules serves as supply air . An additional room ventilation can then be omitted.
    Reference is now made to Figs. 7 and 8. The liquid chemicals necessary for the operation are located in chemical containers 500 (usually containers of 1 m3 (IBC)) and are placed on collection trays 510. For simple exchange of these containers, for example by a fork-lift truck, a double door (600 (see fig. 8) The dosing pumps 520 required for transporting the liquid chemicals are attached to the ceiling 540 of the room module 550 above the chemical containers 500 by means of an appropriate holder 530, as shown in Figures 7 and 8. Protection against splashing in the event of a possible leakage, it is ensured that the dosing pumps 25 and chemical containers 500 are separated from the other built-in components by a curtain 610 of transparent plastic slats (e.g. PVC).
    Glossary
    Container, also standardized container, ISO container A container usually designates containers for a large space for storage and transport of goods. These containers exist in various sizes and are usually normalized and / or standardized. ISO holders are standardized containers for a large space (sea freight holders) made of steel, which make it possible to load, transport, store and unload goods quickly and easily. The relevant standards (for example sizes, holders, stackability) were coordinated by the International Shipping Organization (IMO) and the ISO standard 668 has been laid down. The most widely used ISO containers have a width of 8 feet, a similar height and have a length of either 20 feet or 40 feet. The abbreviations "TEU" (Twenty-foot Equivalent Unit) and "FEU" (Forty-foot Equivalent Unit) used as loading units follow from this. Containers are built in such a stable way that they can be stacked on top of each other in several layers. According to minimum ISO requirements, six fully loaded containers can be stacked on top of each other. The containers are protected with, for example, so-called twistlocks and locking rods / turnbuckles.
    Room module
    Modular holders for a large space as part of an installation, device or building, for example containers. For example, for accommodating technical devices or living and / or working spaces.
    Prefabricated A construction element or module can be prefabricated when it can be manufactured completely in a production installation that differs from the later place of use, so that no additional assembly steps have to be carried out at the location of use of this construction element or module. Rather, this structural element or module can be used immediately after connection to or connection to other structural elements or modules (and possibly after removal of transport protection devices or the like).
