摘　　要：建立分格式序批式活性污泥(SBR)中试装置处理冬季低水温(8～10℃)校园生活污水,考察了空间推流和空间交替运行模式对COD、氮及磷的去除率影响。结果表明,曝气1.5 h各区增设好氧-缺氧空间交替运行效果最好,出水COD为35～60 mg.L-1,去除率达75%～90%,出水磷质量浓度接近0 mg.L-1,去除率高达95%,较仅有空间推流运行省电2/5。3种模式下出水氨氮质量浓度均为20～30 mg.L-1,去除率为20%～45%。温度(15℃和25℃)对氨氮去除率影响试验表明,低温抑制了硝化菌,与延长曝气时间和交替的电子受体环境无关。The pilot scale of cellular sequencing batch reactor activated sludge process（SBR） was invented to treat the schoolyard domestic sewage at low temperature（8～10 ℃） in winter.That the influence of the space plug-flow,space alteration on the COD,nitrogen and phosphorus removal rates were explored.The results showed that cellular SBR with 1.5 h aeration time and the alternating aerobic-anoxic environment could achieve the best performance.The effluent COD was around 35～60 mg·L-1 and its removal rate got to 75%～90%,while phosphorus was lowered down to 0 mg·L-1 and its removal rate reached 95%.Accordingly,its energy consumption decreased 2/5 compared to the space plug-flow mode.However,the effluent ammonia nitrogen was 20～30 mg·L-1 with the removal rate of 20%～45% under three modes.Neither the extention of aeration time nor the change of electric acceptors decreased effluent ammonia nitrogen.Further experiment proved the nitrifying bacteria had been suppressed by low temperature so ammonia nitrogen removal rate improved at 25 ℃.
