摘　　要：考察了不同间歇性曝气实验条件下对陶瓷平板膜生物(C-MBR)工艺污染物去除效果的影响。结果表明,间歇性曝气实验阶段COD的去除效果较好,平均去除率为80.61%;氨氮的去除效果有所提高,出水质量浓度低于10mg/L;脱氮除磷效果有一定程度的提升,TP和TN的最高去除率分别为36.34%、56.74%。综合考虑,间歇性曝气控制为曝2 d停2 d是C-MBR工艺处理校园生活污水的适宜运行参数。The effects of ceramic-membrane bioreactor （C-MBR） process on pollutants removal were investigated with different intermission aeration experimental conditions. Results showed that the COD removal was good, the average removal rate could reach 80.61% during the intermittent aeration conditions. The removal efficiency of ammonia nitrogen was increased, and the mass concentration of effluent was less than 10 mg/L. The nitrogen and phosphorus removal was increased to some extent, and the highest removal rates of TP and TN were 36.34% and 56.74%, respectively. Overall consideration, intermission aeration which alternated with rest for 2 d is the optimized operating parameter for C-MBR process to treat campus sewage.
