On the housing 1. Aerators 9 vertically installed in the upper part of chamber 3, made as a group of jet injectors. A device for adjusting the descend 5; its flow is made in the form of the aeration of the valve 10 hinged at the base of the chamber 3, the water supply unit and sewage in the form of a pump station 11, inside of which are located the tank 12 for water and sewage and the vacuum tank 13 mounted above it. The inlet of the vacuum tank 13 is connected via a pipe 14 to the tank 12 for water and canal lysis waste, and its output through a vacuum pump 15 is connected to the supply pipe 6. Drainage collector. 8 communicates with reservoir 12 for water and sewage. From reservoir 12, water and sewage flows are fed through supply line 6 to aerators 9. To adjust the amount of incoming sewage and water, control valves 16 are installed in aerators 9. Aerators 9 have air tubes 17 through which air is sucked. In the upper part of the aeration chamber 3, a tray 18 is installed to collect foaming soils and foams and drain them along the pipe 19 to the pipeline 20. The upper sections of the pipeline 20 of the drainage collector 8 are equipped with vane 21. At the bottom of the aeration chamber 3 there is a pipeline 22 with regulating fittings 23. Pipeline 22 serves to feed aeration from chamber 3 to drainage manifold 8 for recirculation. An adjusting screw 24 serves to control the shutter 10. The adjusting screw 24 is rotated by a flywheel 25. The shutter 10 is attached to the partition 2 by a hinge 26, and the adjusting screw 24 is fixed to the shutter 10 by a hinge 27. To prevent leakage of fluid from the housing 1 in place the position of the adjusting screw 24 is installed gland 28. At the end of the valve 10 there is a guide visor 29. In the chamber 4 of the collection of active sludge in the lower conical part there is a device for removing sludge and sludge, consisting of a pipeline 30 and stop valves 31. In the lower conical part of the chamber 4 of the collection of activated sludge, there is also a manhole 32 for performing preventive work. In the lower part of the settling chamber 5 there are pipeline 33 and control valves 34 serving to drain part of the wastewater to the drainage collector 8, and in the middle part of the standby chamber 5 there are pipelines 35 and control fittings 36 serving to additionally discharge part of the waste water to recirculation drainage collector 8. The main purpose of pipelines 33 and 35 and control valves 34 and 36 is to change the velocity of the upflows and control the process of sedimentation in the settling chamber 5. In the upper part of the settling chamber 5, a funnel-shaped stream 37 is arranged, which serves to collect the purified water and discharge it through the pipeline 38 to the place of its use. Pipeline 38 is equipped with a fly-tip 39. Case 1 is provided with supports 40, with which it is attached to foundation 41.

The apparatus for the purification of water and sewage with aeration in the downstream works as follows.

Through the supply line 6, through the control valve 16, the drains are supplied from the water tank 12 and the sewage of the pumping station 11 to the aerators 9. In view of the fact that there are a lot of foreign inclusions in the sewage drains, when they enter the aerators 9 they are clogged, their reliability the apparatus in this case is reduced. To prevent this from happening, a vacuum tank 13 is installed in the pumping station 11 of the proposed apparatus for purifying water and sewage with aeration in the downstream, and its entrance through pipe 14 is connected to the tank 12 for water and sewage and the pump 15 is in communication with the supply pipe 6. The vacuum pump 15 creates a vacuum in the vacuum tank 13. Under the influence of the discharge created in the vacuum tank 13, sewage from sewage 12 for water and sewage is sucked into it. Moreover, contained in the sewer. Foreign objects do not get into the vacuum tank 13, but remain at the bottom of the tank 12 for water and sewage, as under the effect of discharge through the pipeline 24, only the water at the top of the tank 12 for sewage and sewage is sucked into the vacuum tank 13 drains that do not contain large foreign objects that can clog the aerators 9. In the aerators 9, due to the intake of air through the air tubes 17, a water-air mixture is formed, which enters the aeration chamber 3. As a result, a water-air downward flow is formed in the aeration chamber 3. By installing the shutter 10 with the help of an adjusting screw 24 by rotating the flywheel 25 to the position at which a gap is formed between the wall of the housing 1 and the clearance plate 29 that allows unhindered passage of fluid from the aeration chamber 3 to the active sludge collection chamber 4 the water / air mixture downstream to the lower part of the aeration chamber 3 in order to increase the efficiency of air oxygen dissolution.

With the appearance of dissolved oxygen in sewage and in the presence of organic pollutants, the development of aerobic microorganisms begins in the aeration chamber 3, which form activated sludge. From the aeration chamber 3, the downstream active sludge enters the activated sludge collection chamber A, where, due to the reduction, it enters the activated sludge collection chamber 4, where due to the decrease of the downward movement speed, the active fluids flocculate and accumulate in the conical part of the chamber 4 collection of activated sludge. Accumulating in the conical part of the activated sludge collection chamber 4, the active sludge forms a microbiological filter.

Constantly entering canalization drains from the aeration chamber 3, enriched with dissolved oxygen and organic matter, filtered in a microbiological filter, create conditions for the viability and rapid development of aerobic microorganisms that are in the microbiological filter. Dead microorganisms: slag, mineralized sludge accumulate in the conical part of the settling chamber 5 and discharged through pipeline 30 and shut-off valves 31 After being filtered into a microbiological filter, sewage is cleaned: the effluent flows into the settling chamber 5, in which to accelerate the process sedimentation. and upstream velocity changes, a portion of the stock is directed for recirculation through conduit 33 and control valves 34 or through conduit 35 and control valves 36.

Purified sewage flows into the upper part of the settling chamber and through the funnel-shaped chute 37 and pipeline 38 are directed to the place of use.
