FIELD: ecology.
SUBSTANCE: invention relates to treatment of effluents. Device comprises installed into sewer manholes filter cell containing two supporting perforated plates, between which a filter material, as well as means for creation of well upstream of treated wastewater and installation of filter cells with provision for passage of said upward flow in upward direction. Filtering material used is a peat load. Filter cell further comprises a filter plate made of porous polyethylene and below top relative to direction of flow of said perforated support plate. One of surfaces of filter plate is rough. Filter plate faces said peat load with said rough surface.
EFFECT: higher quality of purifying waste water due to increased reliability and efficiency of peat load.
