摘　　要：在温度为15．20℃条件下，利用MBR对化粪池出水进行了处理，考察了MBR的生物接触氧化区和超滤膜区对浊度、COD和氮素污染物等指标的去除效果。结果表明：MBR的生物接触氧化区和超滤膜区对化粪池出水的浊度平均去除率分别为8113％和72．3％，对COD的平均去除率分别为37．1％和4．2％，而对TN的平均去除率分别是46_3％和31．5％。从组合式填料上的生物相分析发现了极为丰富的生物相。MBR process has been used for treating septic tank effluent at 15-20 ℃. The effects of biological contact oxidation zone and the ultrafiltration membrane zone of MBR process on the removing efficacies of turbidity, COD, nitrogen pollutants, etc. are investigated. The results show that by biological contact oxidation zone and ultrafihration membrane zone of MBR process, the average removing rates of septic tank effluent turbidity are 81.3% and 72.3%, respectively,average COD removing rates are 37.1% and 4.2% ,respectively,and average TN removing rates are 46.3% and 31.5% ,respectively. Extremely rich biofacies has been found according to the phase analysis on com- bined fillers.
