    OBJECT OF THE INVENTION
    The invention, as expressed in the statement of the present specification, refers to a process of treatment of dangerous liquids for its discharge.
    More specifically, the object of the invention is focused on a process of treatment of hazardous liquid waste from hospitals, chemicals or industry, which is carried out in situ for discharge into the sewer once treated in a treatment plant with the necessary equipment for carry out said process of treatment of dangerous liquids that is installed in the building.
    FIELD OF APPLICATION OF THE INVENTION
    The field of application of the present invention is part of the industry sector dedicated to the treatment of hazardous aqueous liquid wastes, coming from hospital and industry or industry. Specifically, waste that comes from processes with chemical or biological matter with or without solids, which can be highly harmful to both health and the environment. Liquids with a high content of chlorides, metals, BOD (biochemical oxygen demand) and COD (chemical oxygen demand).
    BACKGROUND OF THE INVENTION
    It is known that the removal of aqueous hazardous liquids from hospitals and climates is carried out by managers, with the risk of danger of road transport. Withdrawal is done without prior treatment. Hospitals are required to have a clean point, where dangerous liquids are taken.
    It is also known that hospitals and hospitals are storing these liquids, with a limited time, until their withdrawal.

    Today there is no such procedure that is carried out in situ for the treatment of dangerous liquids in hospitals and clinics. Currently, until its withdrawal, the products accumulate in a clean spot. The handling interventions are several, with the risk of contamination and personal injury. The liquids are removed by managers, with new handling of drums and containers, pumping, road transport and discharge, with new risk of environmental pollution and personal injury.
    EXPLANATION OF THE INVENTION
    The process of treatment of hazardous liquids that the invention proposes applies, for example, to aqueous products from clinical analysis laboratories in hospitals and clinics or that come from processes with chemical or biological matter with or without solids in industries. Immediate, continuous, 24h / 365d and on-site.
    Thus, before their treatment, the liquids arrive directly, preferably by canalization without any previous manipulation, to different accumulation deposits provided in the plant, which is installed on site, that is, in the building itself that generates said liquids.
    If the channeling, due to the structure of the building, is difficult, there is the possibility
    5
    10
    fifteen
    twenty
    25
    30
    35
    of unloading the illiquids, without direct contact, in the different accumulation tanks of the treatment plant.
    And after their treatment, the waste obtained is discharged to the sewer, always complying with the current Municipal Ordinances.
    Specifically, the treatment process includes the following:
    Hazardous liquids accumulate in different accumulation tanks, depending on their origin and composition, and can be mixed or separated due to their danger and non-compatibility with others. In case there is no canalization, the plant has a discharge station for drums, bottles or any container, for emptying to the accumulation tanks.
    At the moment that one of the accumulation tanks arrives at a sufficient volume for a treatment, an evaporator is automatically charged, by pumping or by its own dump. Once the liquid reaches a specific level in the evaporator, the first phase of treatment itself begins.
    The evaporator is equipped with a heating system with a heat pump, and operates, preferably, at a pressure below the atmospheric of 5 kPa and a temperature of approximately 30 ° to 34 ° C, although it can cover between 10 ° to 100 ° C.
    The temperature exchange takes place in a heating jacket, of conical or flat type. Existing heat and cold systems and means can also be used in the user's building.
    The inside of the evaporator jacket is continuously cleaned with an internal scraper, this configuration allows a high concentrate and a distillate with a very low conductivity. There is the possibility of process without scraper. The heating of the liquid can be carried out directly or indirectly. The process capacity is variable in terms of the number of liters per day.
    The evaporation-concentration technique separates the aqueous parts from the
    5
    10
    fifteen
    twenty
    25
    30
    35
    pollutants, which may be dissolved or suspended. This results in a fully purified distillate and a concentrate that significantly reduces waste management costs.
    Another advantage of the scraper is the impediment of the formation of scale inside the heating jacket. Depending on the type of liquids to be treated, a scraper can be used or not.
    Following evaporation, the steam is condensed in a condenser. The result is a purified distillate.
    The condenser is continuously strained in a neutralization reactor. When a certain level is reached, an agitator provided in it starts.
    According to the pH allowed by the current Municipal Ordinances for the discharge of waste to the sewer, reagents are dosed to raise or lower said pH. This process is continuous or discontinuous. Since the conductivity of the liquid after evaporation and condensation is very low, the cost of the pH corrector is minimal.
    The continuous or discontinuous process is programmable. Evaporation is variable, depending on whether continuous or discontinuous neutralization.
    Depending on the types of liquids to be treated, in addition, a silicone-free or silicone-containing antifoam is dosed during the process, at defined points depending on the liquids that can cause foams.
    After a certain waiting time, if there are no changes in the pH, conductivity or other parameters, an expulsion pump starts which leads the liquid to the sewer, previously passing the residue through an active carbon filter.
    If this is not the case, an alarm is activated in the electrical panel with which the plant is equipped, displaying the type of fault for a technician to act.
    Adsorption by the active carbon filter is a step where a solid is used to remove soluble substances, such as the possible solvent content from water, such as a
    5
    10
    fifteen
    twenty
    25
    30
    35
    final safety treatment Granular activated carbon (GAC) is used in the filter. The activated carbon filter is necessary or not according to the liquids to be treated.
    In the event that the programmed pH and conductivity values are within the minimum and maximum required parameters, a disinfectant dosing pump starts at the same time that the ejection pump starts at the sewer.
    For safety, the residue passes through an ultra violet light with a wavelength of 254 to 270 nm.
    The passage of the residue through said wave is aimed at controlling and eliminating microorganisms, damaging their DNA (deoxyribonucleic acid). The damage caused by ultraviolet light has no known negative effects on water. Ultraviolet light penetrates the cell wall of a microorganism and causes a reaction in the DNA of the microorganisms, breaking the carbon bond C = C. This causes cell death, making the microorganism unable to grow and multiply.
    In the event that the liquid disinfectant fails, either due to lack thereof, due to dysfunction of the dosing pump or for another reason, the ultra violet light will function as added security with a continuous disposition.
    The plant has a tap for sampling, before leaving the sewer.
    All parameters, such as pH, conductivity, treatment cycles and anomalies, are stored in the memory of the automaton that has been provided within the electrical panel, optionally considering the possibility of its storage in an external memory.

    As seen in said figure 1, the treatment process is carried out in a plant installed on site and comprises the following phases:
    - Collection of dangerous liquids in one or more storage tanks (2), which are between 100 and 5000 liters in volume, are made of materials resistant to them, such as polypropylene, stainless steel, polyethylene or other materials , are rectangular, square or cylindrical, with or without platform, underground or not and, in any case, preferably, they are endowed with permanent control by level probes (3). Said collection, preferably, is carried out directly through a channeling, although, in case there is no channeling, it is carried out in a station (20) for discharging drums, for pumping, or other form of emptying, to the tanks of accumulation (2).
    - Evaporation, in an evaporator (6) that is filled automatically, with the liquids from the accumulation tanks (2) when any of them arrives at the planned level, by means of a loading pump (18) and, preferably, has a scraper (21) which, in the preferred embodiment, starts at the same time as said pump. Although evaporation is continuous, accumulation deposits (2) can continue to store dangerous liquids. The liquid transfer from the accumulation tanks (2) to the evaporator (6) is carried out by means of automatic (27) and / or manual valves (28) and the filling of the evaporator (6) is carried out under control by an internal level probe (not represented).
    To achieve evaporation, the evaporator (6), preferably, is equipped with a heating system with a heat pump, and preferably operates at a pressure below the atmospheric temperature of 5 kPa and at a temperature between approximately 30 and 34 ° C.
    In case there are not enough dangerous liquids in the accumulation tanks (2), the process is put in “Stand By.” At the moment when there are enough dangerous liquids in the accumulation tanks (2), it follows the process automatically.
    - Condensation in a condenser (7), which is in line, in direct or indirect contact, with the vapor of the evaporator (6) and is operated with it converting said steam into a distillate. For said condensation, the condenser (7) uses the temperature of a cold / heat pump (not shown) or any external source or combination of both.

    - Neutralization of the distillates obtained by reagents, which is carried out in a neutralization reactor (8) consisting of a container of polypropylene, stainless steel or polyethylene material of rectangular, square or cylindrical shape with a volume between 100 and 4500 liters that is fills under control of another level probe (3) continuously with the outgoing distillate of the condenser (7). When it reaches a certain level, controlled by the aforementioned level probe (3), an agitator (22) provided in it starts.
    The neutralization in the neutralization reactor (8) of the distillate is carried out, at a pH controlled by a pH and conductivity probe (14), with reagents from two tanks provided for that purpose, a container of pH + reagents (alkaline) (12) and another of pH- (acid) reagents (31) to increase or decrease the same, and whose discharge is carried out with corresponding metering pumps (30), always complying with the Municipal Ordinances regulating the discharges to the network of sewer in force. The reagent container tanks (12 and 31) are controlled under level probes (3).
    - Filtering and disinfection. When the pH and conductivity values of the product, programmed in the control panel automaton (1), and controlled through the aforementioned pH and conductivity probe (14), are within the minimum and maximum required parameters, it starts a disinfectant dosing pump (11), incorporated into a disinfectant tank (19), at the same time that an expulsion pump (13) starts from the waste to the sewage system and disinfectants in it, through the corresponding pipe (10) ), after previously passing the residue through an active carbon filter (9) provided after said expulsion pump (13). The disinfectant tank (19) is also controlled by a level probe (3). On the other hand, the expulsion pump (13) bends the neutralization reactor (8), under the control of another level probe (3) provided in it, until it is complete and the treatment process starts again.
    It is worth mentioning that disinfection is carried out by means of any reagent or liquid and / or gaseous product, and the treatment may also incorporate coloring, liquid, or solid products.
    - Security disinfection. Preferably, for safety, the residue passes through an ultra violet light (17) of a wave between 253.7 to 270 nm located before the sewer drain (32).
    - Sampling. Optionally, sampling of the residue is contemplated, to
    through a sampling tap (16) provided before its exit to the sewer.
    This sampling tap (16) and the pipes from the neutralization reactor (8) and the active carbon filter (9) to the sewer outlet (32) incorporate 5 corresponding automatic (27) and manual valves (28) .
    On the other hand, all parameters, such as pH, conductivity, treatment cycles and anomalies / alarms are recorded in a register (15) in the memory of the automated processor provided within the electrical panel (1) that controls the entire system, 10 contemplating the possibility of an external memory. The warning of anomalies is done through any means.
    Finally, the process includes the control, automatic or manual, of concentrated sludge and its manual or automatic evacuation.
