SEWAGE PURIFICATION STATION Russian patent published in 2007 - IPC C02F9/12 C02F1/32 

FIELD: environmental protection; devices for biological purification of the sewage.

SUBSTANCE: the invention is pertaining to the sewage purification station, which may be used for biological purification of the sewage. The purification station includes: the lattice, the aerated sand catcher, the sand site, the primary and secondary settling tanks, the screen, the tank-store of the washing water, two step-up pumps, the vertical-tubular system, the jet apparatus, the auger-shaped vane, the source of the industrial oxygen, the cock with the floating-type drive, the concentratometer of the dissolved oxygen in the sewage, the setting device, the comparator, the servo drive, the gate, the pressure transducers, the electrified shutters, the sensors of the electrified shutters positions, the control unit. At that the station additionally contains the haze meter, the functional transformer, the switch, the second jet device, which mixing chamber is made out of the quartz glass, the ultra-violet radiating unit, the ozonator, the concentratometer of the dissolved ozone in the sewage. And the ultra-violet radiating unit consists of the separate ultra-violet lamps arranged axially concerning the quartz mixing chamber. The haze meter is mounted at the outlet of the screen. The outlet of the haze meter is connected to the inlet of the functional transformer and through the control unit and the switch - with the lamps of the ultra-violet radiating unit. The technical result of the invention is the increased efficiency of purification of the sewage at the characteristics of inlet stream of the liquid varying within the running time.

EFFECT: the invention ensures the increased efficiency of purification of the sewage at the characteristics of inlet stream of the liquid varying within the running time.
