Description

t

The invention relates to a water and sewage treatment plant and is used in sewage treatment at livestock and pig breeding complexes, poultry farms and laundries, in circulating water supply and irrigated agriculture.

The purpose of the invention is to improve the quality of sewage and water treatment, reduce the cost of construction and installation work and operation and improve working conditions.

The drawing shows the proposed device.

The apparatus is a vertically installed column with a height of 15-20 m, in which case 1 divides the partition 2 into the aeration chamber 3, the chamber 4 for collecting activated sludge and the settling chamber 5. In the upper part of the aeration chamber 3, a group of injectors 6 is installed, into which a conduit 7 is supplied with drains or water from a pumping station. To regulate the amount of wastewater entering the injectors, a control unit 8 is installed. Air is drawn through the air tubes 9 into the injectors 6 In the upper part of the aeration chamber 3, a tray 10 is arranged to collect the pollutants and foam and discharge them through pipeline 11 to the pipeline 12. Above the tray there is an overflow pipe 13 through which drains or water is discharged into the drainage collector 14. The upper sections of pipelines 12 and 13 are equipped with fly-flaps 15. At the bottom of the aeration chamber there is a pipeline 16 with regulating valves 17, the purpose of which is part of the effluent from the aeration chamber to feed into the drainage collector 14 for recirculation. To regulate the flow rate of the downflow, a valve 18 is installed in the aeration chamber, which is controlled by an adjusting screw 19. The screw 19 is operated by a flywheel 20. The damper is attached to the partition by a hinge 21, and the screw is fixed with a flap by a hinge 22. The water-tightness of the apparatus in the housing is carried out by an epiploon 23. At the end of the flap there is a guide visor 24. In the collection chamber of active sludge in the lower conical part odits device for removing sludge and sludge consisting of the pipe 25 and valves 26.

, To perform maintenance work inside the apparatus, there is a device consisting of a hatch 27.

In the lower part of chamber 5, 5 NIN, there is a device for diverting part of the waste for recirculation into the drainage pipe 14, consisting of pipe 28 and regulating reinforcement 29, and in the middle part - arranged for additional removal of part of the waste for recirculation into the drainage manifold 14 consisting of pipeline 30 and control valves 31. The main purpose of the pipeline :; Ode 15 28 (30) and control valve 29 (31) is the change in the upflow rate and control of the sedimentation process in the settling chamber 5. In the upper part of the chamber 5, the funnel-shaped tray 32 is arranged, which serves to collect the purified water and dispose through the pipeline 33 for its intended purpose.

The apparatus is fixed 25 on supports 34 to foundation 35. Service platforms are not shown conventionally. The proposed apparatus works according to the following scheme.

Example 1. When cleaning wastewater

or water containing oil contaminants, fats, modern detergents; sewage flows from pumping stations through a pressure pipe 7 through a regulating valve 8

injectors 6. Air is sucked up. into the injectors through the tubes 9. The mixture formed in the air-to-air mixture in the injectors is fed into the aeration chamber, which forms the downward water-to-air

flow. By placing the shutter 18 in position with the screw 19 using the flywheel 20, the downward movement speed is reduced. Then the air bubbles will begin to sprinkle to the surface of the aeration chamber and remove contaminants containing petroleum products, fats, modern detergents, foam (flotation method), which are collected in tray 10 with pipeline 11 and discharged into pipeline 12 spontaneously.

Refined from oil products, fats and modern detergents, but enriched with dissolved oxygen

sewage flows into chamber 4, where partial sludge and sludge occurs. Pass the chamber 4, the drains flow into the settling chamber 5, where with the help of

the control valve 29 (31) and the pipe 28 (30) adjust the outflow rate. The purified water enters the funnel-shaped tray 32 and is discharged through conduit 33 to the destination. The sludge and sludge is discharged from the conical part 4 through pipe 25 and shut-off valves - RU.26.

Example 2.-If the device has manufactured fittings 26.

leads to the treatment of sewage or water from organic and inorganic contaminants, then through pipeline 7 through the regulating valve 8 effluents flow

the injectors 6, in which the T5 substitution and change of velocity are lifted from the air through the tubes 9, and the resulting air / water mixture in the injectors enters the aeration chamber, forming a water downward flow. By setting the shutter 18 with the screw 19 and the flywheel 20 to position S, conditions are created for suction of the water-air mixture in a downward flow to the lower part of the aeration chamber in order to decrease. air oxygen dissolution efficiency. With the appearance of dissolved oxygen in the drains and in the presence of organic pollutants, the development of aerobic microorganisms begins throughout the entire capacity of the apparatus, which forms the active sludge.

From the aeration chamber, downstream activated sludge enters the activated sludge collection chamber, where, due to a decrease in the downstream movement velocity, activated sludge flocculates and accumulates together with other contaminants in the conical part of the activated sludge collection chamber.

During further operation of the apparatus, the active sludge fills the entire capacity of the chamber, forming a microbiological filter,

In order to flow, a portion of the effluent is directed for recirculation through conduit 25 and shut-off valves 26.

Filtered in the microbiological filter, the treated effluent or water enters the sludge chamber, in which, to speed up the sedimentation process and change the upstream flow rate, part of the effluent is sent for recycling through conduit 28 (30) and control valve 29 (31).

The main purpose of recycling and in the case of an upstream flow velocity is to accelerate the processes of sedimentation in the sludge chamber,

Purified sewage or water enters the upper part of the settling chamber, where through tray 32 and conduit 33 it is diverted to its intended purpose.

The proposed apparatus for the purification of water and sewage with aeration injectors in the downstream; having a higher height (15–20 m), creates pressure up to 1.5–2 atm per charge of the liquid column and transports purified water or drains without an additional device for the required distance. The time for cleaning the wastewater or water is reduced three times.

Substances filtering in a microbiological filter create conditions for the viability and rapid development of aerobic microorganisms found in the microbiological filter. Dead microorganisms, sludge, mineralized sludge accumulate in the conical part of the settling chamber and are discharged through the pipeline 25 and the filtered wastewater or water enters the chamber in a sieve, in which to accelerate the processes of sediment.
