摘　　要：采用厌氧-接触氧化串联工艺处理电厂生活污水。结果表明,在DO质量浓度控制为2～4 mg/L,水力停留时间为0.8 h,水力负荷为3.33 m3/(m2.h)条件下,进水COD为350～600 mg/L,BOD5为320～350 mg/L,SS、NH4+-N质量浓度分别为330～400 mg/L、60 mg/L时,出水COD相对平稳,基本上都在55 mg/L左右;出水BOD5一直处于20 mg/L以下,出水SS质量浓度稳定在10 mg/L。出水氨氮质量浓度均保持在10 mg/L以下。出水水质应满足GB18918-2002城镇污水处理厂污染物排放标准。In this paper,anaerote-contact oxidation process was used for domestic waste water of plant treatment,the results showed that when the content of DO was 2～4 mg/L,hydraulic retention time was 0.8 h,hydraulic load was 3.33 m3/(m2.h),and the concentrations of COD,BOD5,SS and NH4+-N in the influent were 350～600 mg/L,320～350 mg/L,330～400 mg/L,60 mg/L,respectively,the effluent COD was relatively stable,basically all around 55 mg/L;effluent BOD5concentration was below 20 mg/L,effluent SS concentration was stable in 10 mg/L;The effluent NH4+-N was maintained below 10 mg/L.Water quality met with GB 18918-2002 town sewage treatment plant pollutant discharge standard.
