PLANT FOR REMOVAL OF SYNTHETIC DETERGENTS FROM FECAL DOMESTIC SEWAGE Russian patent published in 2001 - IPC

FIELD: bacterial treatment of fecal domestic sewage for removal of synthetic detergents. SUBSTANCE: plant has a catcher, sand trap, reactor with transverse partitions to form chamber. Located along reactor axis are mixing turbines mounted on vertical drive shaft. Lower chamber is communicated with air blower. Installed between air blower and chamber is mixer of air with oxygen, and centrifugal microfilter. The latter is communicated by biomass with dynamic disintegrator with branch pipes. Rotor is installed along axis of dynamic disintegrator and having blind holes engaged through circular channel with holes of perforated ring which forms a cavity together with disintegrator body. The cavity is isolated from inlet and outlet branch pipes and communicated with next stages of disintegrator by branch pipes. Disintegrator is communicated with electrolysis chamber, anode and cathode sections. Anode section relative to oxygen is communicated with mixer installed between air blower and reactor chamber. Reactor chambers are made with perforated immobilizing partitions. EFFECT: higher efficiency of treatment. 1 dwg
