摘　　要：应用UASB混凝沉淀法对高浓度屠宰废水的处理进行了试验研究。用UASB反应器处理屠宰废水,CODCr容积负荷可达6.8g(L·d),CODCr去除率达93%左右,并对UASB出水投加一定量的混凝剂PFS和助凝剂MZ,实验表明:系统出水达到《肉类加工工业水污染物排放标准》(GB1345792)二级标准。The process of UASB reactor and coagulation-sedimentation was used to study treatment of high concentration slaughterhouse watewater.With UASB reactor to treat slaughterhouse wastewater,the volume load of COD_ Cr could reached 6.8g/(L·d),and the removal rate of COD_ Cr was about 93%.A certain quantity of poly-ferric sulfate and auxiliary agent MZ was added to the effluent of UASB,the experimental results showed the effluent of slaughterhouse wastewater system could be up to the second order of “Discharge Standard of Water Pollutants for Meat Processing Industry”(GB13457-92).
