Abstract

This invention relates to the biological treatment of wastewater. The purpose of the invention is to increase the degree of cleaning, increase reliability in operation and ensure compactness. The station contains aerotanks, clarifiers 4 and 5, control unit 3,: clarification chambers 10 and 11, settling chamber. for: ki 12 and 13 with filters 14 and 15 before wastewater treatment, submersible electric pumps 16 and 17, connecting pressure flexible elements 18 and 19 with aerators 20 and 21, equipped with air intake pipes from the control unit and outlets 24 and 25 to create a directional hydraulic flow. In the aeration tanks 4 and 5, submersible electric pumps 16 and 17 through flexible pressure gages 18 and 19, the sludge mixture is fed to aerators 20 and 21j causing air to leak from the atmosphere (in winter from the control unit). Then, the silt mixture, partially clarified in the clarification chambers 10 and 11, is poured into settling basins 12 and 13, where it is finally clarified and undergoes purification on filters 14 and 15.

Description

The invention relates to biological purification, and it can be used locally in rest homes, sanatoriums, in pioneer camps for cleaning domestic and near water composition,

The purpose of the invention is to improve the treatment of waste water, reliability of operation and compactness of the station.

The plan shows a stacking case in FIG. 2 is a section A-A in FIG. 1., In section B-LZ in FIG.

The station contains connected flat covers (not shown). blocks of containers 1 and 2. between which control block 3 is installed; blocks of biological cleaning, made in the form of aerotanks clarifiers 4 and 5. In the latter, partitions 6 and / form aeration chambers 8 and 9 and chambers 10 and 11 of lighting 5, sumps 12 and 13 have filters 14 and 15 of additional water purification, At the bottom of the aerotank clarifiers 4 and 5, submersible electropumps 16 and 17 are installed, connected by pressure flexible elements Р 18 and 19 from aera 20 and 21, having pipes: 22 and 23 for taking air from control unit 3 and outlets 24 and 25, made under angles for creating & no directional hydraulic noTOKaj pipeline 265 drain trays 27 and 28 with p Brushes 29 and E 30 for detention krugshskh suspensions, thin-film modules 31 and 32 are prefabricated trays 33 and 34, kondensatnsh tank 35 pump 36 filter washing LDK 14 and 15; the electrolyzer 37 installed: in the control unit 3, the thin-layer modules 38 and 39 e installed

lent in settling tanks 12 to

40 and 41 sludge return pipelines.

The station operates as follows:

Pipeline 26 one hundred, E, water is served in the cream trays 27 and 2o. Which lattices 29 and 30 prevent the passage of large: suspended matter; and the water is poured from the aeration chambers 8 and 9 of the aerotank clarifiers 4 and 5. The submersible Tronasosyad 16 and 17 electrolytic cells through flexible electrified gas 18 and

19feed sludge mixture aerators

20 and 21J, thereby causing air to leak from the atmosphere (in winter from the room). Bends 24 and 25 contribute to the creation of directional guides.

in the aeration chambers 8 and 9, thereby eliminating stagnant zones, 1 1 - the mixture of aeration chambers B and 9 is moved under partitions 6 to 7 in chambers 10 and

12 and 13, returns to aeration. chambers 8 and 9 of aerotank clarifiers 4 and 5, Purified water is supplied to filters 14 and 15 of the purification process, where its final clarification and purification is carried out. Due to the rarefaction of the working stream generated by the pulsed kinetic energy, 20 and 21 through the pipelines 40 and 41 return sludge from the settling tanks 12 and 13 enters the aeration chambers 8 and 9 of the aero-clarifiers 4 and 5, Purified water serves 3 contact tank 35 and disinfects with sodium hypochlorite, and produces: v electrolyzer 37 in block 3 y a systematic way. Through the pump. 36, the filters 14 and 15 are washed.

The proposed station of a compact land-based sewage treatment plant is simple in design, ensures reliable operation and improves the quality of wastewater treatment.
