摘　　要：采用内循环厌氧反应器(IC)/好氧生物工艺处理高浓度苹果汁生产废水。废水水量为1200 m^3/d,进水COD为2000~10000 mg/L,pH值为5~7。废水经处理后,出水COD≤60 mg/L,满足《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级B排放标准。IC反应器对COD的去除率高达90%以上。该工程投资为425万元,运行电费为1.85元/m^3,药剂费约0.96元/m^3。The internal circulation(IC)anaerobic reactor/aerobic biological process was used to treat high concentration apple juice wastewater.The influent quantity was about 1200 m^3/d and influent COD concentration was 2000-10000 mg/L and pH value was 5-7.After treatment,the effluent COD≤60 mg/L,which could reach the first level B discharge criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).The COD removal rate of IC reactor was over 90%.The project investment was 4.25 million yuan and the operation electricity cost was 1.85 yuan/m^3 and chemical agent cost was about 0.96 yuan/m^3.
