The invention relates to a kitchen waste sewage treatment system, comprising a pretreatment system and a biochemical treatment system connected in sequence, wherein the biochemical treatment system adopts a biological turntable device (BBR device), and the material of the biological turntable disc is composed of partial The modified PVDC polymer obtained by copolymerization of vinyl chloride, 1,2-vinylidene chloride, glycidyl methacrylate and cationic monomer, and the filament and latex made of auxiliary materials are heat-set to form a three-dimensional network structure. The invention has the advantages of simple process flow, high effluent compliance rate, easy sludge treatment, high efficiency and energy saving, low operation cost and small land occupation, and is very suitable for the treatment of kitchen waste sewage. The biological turntable in the BBR equipment of the present invention forms an anaerobic, anoxic and aerobic environment inside the disc, and combined with the anaerobic, anoxic and aerobic environment at the microscopic level of the biofilm itself, it exerts stronger synchronization Nitrification and denitrification, saving operating costs and residence time of biochemical pools. |
