BIOREACTOR FOR CLEANING OF AQUATIC MEDIUM Russian patent published in 2016 - IPC C02F9/14 C02F3/06 C02F3/10 C02F3/12 C02F1/48 B01D36/00 B01D24/12 

FIELD: ecology.

SUBSTANCE: invention relates to environmental protection and can be used for cleaning of natural and after purification of storm and sewage waters. Bioreactor for cleaning aquatic medium consists of body 1, equipped with windows for air leak 2 with aerating ducts 3, dome-shaped reflector 4 with device for air outlet 5, with pipelines of giving of the initial water medium for cleaning 6, offset for the purified water medium 7, collapsible distribution system 8, connected with a pipeline of offset of washing water 9. Inside the case 1 are located aeration zone 10, filtration zone 11 and settling zone 19 with modules of thin-layer settling 20. Aeration zone 10 consists of distributing chamber 12 with radially connected with it at least four tubes 13, equipped with jet-forming nozzles 14. Filtration zone 11 is equipped with layers of big-grained 17 and small-grained 18 floating loading. Case1 in upper part of the filtration zone 11 is equipped with at least two solenoids 21. Settling zone 19 is located around the lower part of the filtration zone 11. Ratio of diameters of the filtration zone 11 and settling zone 19 makes at least 1:3.

EFFECT: invention allows to increase the degree of cleaning aquatic medium, reduce the volume of washing water and reduce operating costs.
