INSTALLATION OF BIOLOGICAL PURIFICATION OF THE WASTE WATERS Russian patent published in 2006 - IPC C02F3/02 

FIELD: biological purification of the waste waters; installations for biological purification of the waste waters.

SUBSTANCE: the invention is pertaining to the field of purification of the waste waters and, in particular, to biological purification of the small and middle volumes of the waste waters. The installation of the biological purification of the waste waters contains the housing, the waste waters receiving tank, the ejectors, the pump for ejection of the waste water, the pump for pumping out and ejection of the purified water, the biofilter, the spray jet and the sensors of parameters of the being purified medium. The sensors of the parameters of the purified water include the sensor of the volumetric concentration of the dissolved oxygen connected through the comparison unit containing the preset value and with the a control unit for the pump ejecting of the waste water. The biofilter contains the additional plates made out of the same material used in the biofilter itself; one the sides of each plate is rigidly linked with the biofilter and is arranged in parallel to the central axis of its housing. The technical result of the invention is the increased efficiency of operation of the installations for biological purification of the waste waters at a minimum level of power inputs due to activation of the biological vital functions of the micro-organisms.

EFFECT: the invention ensures the increased efficiency of operation of the installations for biological purification of the waste waters at a minimum level of power inputs.
