    The invention relates to the field of biological wastewater treatment using chemical cleaning, if necessary, and methods to activate sludge and clarify the sludge mixture.
    The purpose of the invention is to increase the oxidizing capacity of a device for the biological treatment of wastewater by increasing the amount of oxygen introduced into the wastewater. .
    Fig „1 shows a device for biological wastewater treatment; Fig 2 is the same, top view; on fig.Z - the same, longitudinal section, option; Fig, 4 - the same, top view.
    The device for biological treatment of sewage comprises a cylindrical tank 1 "in which the partition 2 is arranged coaxially, made in the form of a reverse-truncated cone (Fig. 1) with a large base located at the level of the liquid in the structure. The smaller base of the bulkhead is at the bottom of reservoir 1 or slightly above it. The annular space between the partition 2 and the wall of the tank 1 is a secondary aeration tank 3, at the bottom of which a scraper 4 is provided for scooping sludge. The secondary settling tank 5 is located in the central part of the tank, and the bottom scraper 6 is rotated
    Ci is a real tank 17, where the air-saturated sediment is mixed with the aerotank liquid 3 and with the original liquid. The resulting mixture is kept in the annular space 20, which functions as a degasser and a tertiary settling tank, and the annular space of the aerotank 3 is fed to treatment. Due to the separate aeration of the waste water and sediment, the introduction of oxygen improves and the oxidative capacity of the structure decreases and its volume decreases. reduced operating costs. 1 h, n ,. f-ly, 4 ill.
    scavenging sludge into the central recess for its collection — sludge at mock 7 from which sludge is sucked through the central suction pipe 8 by means of the sludge pump 9 and sent to a separating device — centrifugal separator 10 — spaced on the discharge pipe 11. The separator has top overflow 12 and a bottom discharge 13 with a regulative valve 14 connected to the aerator 15 having aeration holes 16.
    The device has a mixing tank 1 7, a 1yus essentially a primary aerotank where they mix oxygen-rich sediment with a liquid from an aerotank 3 that is aerated in aerator 18 through aeration holes 19. Outside, tank 1 has an annular space 20 that functions as a degasser and tertiary the sump With the aid of the elevator 21 with aeration holes 22, the liquid is supplied to the air tank 3. The elevator 21 at the outlet has a side port 23, by means of which the liquid is twisted in air kyo. The surface water in the aeration tank 3 is collected through the chute 24 and through the drain pipe 25 is supplied to the central descending channel 26 in the secondary clarifier 5. The chute 24 is made double
    middle partition, serving z liquid level. If the outer half of this gutter collects surface water from the aerotank, the inner half collects clarified water from the secondary sedimentation tank and leads it through pipeline 27. Fresh wastewater is supplied through pipeline 28 and riser pipe 29.
    As an example, the implementation of aeration pipelines or return pipes in three fields is shown (Fig. 2). In practice, their number is determined by economic considerations. For example, FIGS. 3 and 4 show a simplified construction of the device with five planes of symmetry. FIG. 3 shows mixing tanks .17 located separately from tank 1 and containing overflow chute 30 with radial channels 31.
    The holes 32 serve to transfer the water to be aerated from the aero tank 3. In the secondary settling tank there is an annular slot 33 through which the clarified water passes and enters the chute 24 through the partition 34 The holes 32 are connected through channels 35 and 36 to pumping pump 37. I
    The device works as follows.
    Fresh wastewater to be aerated is fed into the riser pipe 29 from line 28, aerated and sent to a mixing tank 17. The mixed liquid is directed into the annular space 20, in which partial degassing takes place by increasing the free surface or reaction time before the liquid through the lift 21 is re-aerated with the help of aeration holes 22 and brought to the aerotank 3. The outlet of the lift 21 contains more New tube 23 (figure 2), by which the fluid in the annular space of the aerotank receives a twist, which contributes to an increase in the degree of mixing (and this in turn prevents precipitation. shrinkage), and a longer residence time of the reaction is achieved. The surface water of the aerotank 3 is collected through the chute 24 and from it through the pipe 25 is brought to the central downstream channel 26 in the secondary settling tank 5, where the sludge itself is separated from the clarified water. The clarified water is collected in the gutter 24 and discharged through the discharge pipe 27. In the secondary clarifier 5, the bottom scraper 6 rakes the precipitated sludge into the central recess for its collection - (sludge at the bottom 7), from which the sludge is sucked through the central suction pipe 8 with the help of sludge pump 9 and raise above the level of the liquid secondary sump 5.
    In a separating device located in the discharge pipe 11 after the sludge pump 9, the sludge is divided into two partial flows, which are removed from the upper overflow 12 and the lower discharge 13 of the centrifugal separator 10. The centrifugal pump is expediently performed as a cyclone, the more active bacterial strains are in the bottom discharge 13, while in overflow 12 there are more dead, therefore, residents of the sludge who have lost their activity. In the drain 13, a control valve 14 is provided, with which it is possible to regulate the amount of sludge passing through the drain or overflow.
    The overflowing overflow of 12 sludge is discharged in the form of excess sludge. In this case, the drain 13 is connected to the aerator 15, where the sludge absorbs oxygen from the air, as it passes by the aeration holes 16 and thus loses or is supersaturated with oxygen, i. When conducting aeration sediment
    there is an increase in activity, since the more active inhabitants of the sediment absorb the old bacteria that have lost their activity, resulting in their regeneration. This packed sludge is introduced into a mixing tank 17, where it is mixed with liquid from an annular aerotank 3, which is aerated in a similar aerator 18 by means of aeration holes 19. During purification of some wastewater, in particular chemical wastewater,
    are in overflow 12 and therefore in these cases overflow 12 is connected by an aerator 15, and drain 13 is designed as an outlet pipe for excess sludge. Since the liquid and the sediment have different oxygen requirements, and also the reaction time of the reaction is different, with the help of the proposed device it is possible to ensure optimal degassing.
    In the embodiment of the device (Fig. 3) there are separately located mixing tanks. The partitions separating the central settler 5 from the aeration tank 3 are so steep that they do not contain precipitated sediment. Sludge through the top of the suction pipe 8 inlet to the sludge pump 9, and this suction pipe 8 is designed as a central recess for sludge,. Aerotank 3 has a conical bottom part. The apertures 32 for sucking the quantity of liquid necessary for aeration are approximately in the area of the apex of the cone, which makes it possible to refuse the use of sludge scrapers and to simplify the design of the device. If necessary, the holes 32 can go out into the suction pipe 8, which can save the pump. This should include a flow control device or shut-off valve.
    Pipeline 25 may also be guided directly from the aero tank 3 to the downstream channel 26; where the sludge is separated from the liquid Clarified water rises through the annular gap 33 into the upper part of the secondary clarifier and through the passage 34 flows over into the chute 24, where the clarified water is diverted through the discharge pipe 27. The discharge pipe 27 for the clarified water can pass through the aeration tank 3 If cleaning of the bottom of the aerotank 3 is envisaged, removal of the clarified water is carried out through a lift, which is connected to the sludge scraper bridge and diverts the clarified water into a yellow water channel designated for this purpose. a (not shown).
    Owing to the separate aeration of waste water and sludge, the introduction of oxygen is improved and it becomes possible to reduce the volume of purification chamber.

    moves associated with its operation. During subsequent mixing, degassing does not occur and therefore the residence time of the absorbed gas is increased, and part of the gas is biologically and / or chemically bound. The content of the off-gas (CO) is removed and therefore the fluid is degassed before the next / next airflow. The degassed fluid at the nearest site of aeration intensively absorbs oxygen, which is biologically and / or chemically bound in the secondary clarifier. Therefore, the sludge is kept in the secondary sedimentation tank for a short time, it remains suitable for reuse.
