DOMESTIC SEWAGE EFFLUENTS TREATMENT PLANT Russian patent published in 2013 - IPC C02F3/00 C02F11/04 C12M1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to biological treatment of domestic sewage effluents. Effluents are fed from collector 1 into anaerobic digester 2. Contaminated biogas is fed from methane fermentation chamber 6 into inlet branch pipe 38 and is forced by pump 11 in discharge branch pipe 39. Contaminants are fed into appropriate collector 45. Processed biogas is fed into chlorella generator 12. Pure methane is collected in collector 12. Chlorella and thiobacteria are forced via branch pipe 16 into dynamic disintegrator 15. Mix of heavy and standard water is fed via hydraulic gate 19 into rectifier 20 to produce heavy and standard water. Heavy water is directed from heat exchanger 28 into circulation circuit 31 of reactor 32. Portion of the mix of standard and tritiated water is directed into extra rectifier 35. Tritiated water is separated from standard water and directed into collector.

EFFECT: higher efficiency of treatment.
