| 摘 要： | 对间歇循环延时曝气(ICEAS)工艺处理模拟城市污水进行了研究,结果表明,在运行周期为4.5h,污泥负荷在0.07~0.09kgBOD5]/(kgMLSS]·d)的条件下,出水COD的质量浓度为15.2~42.2mg/L,COD去除率达80%~88%;BOD5的质量浓度为5.12～16.9mg/L,去除率可达85%～93%;氨氮的质量浓度为4.5～7.5mg/L,去除率为60%～70%,磷的去除率为60%～75%。说明ICEAS工艺处理南方地区城市污水是可行的。

| Abstract: | The treatment of simulated municipal sewage by an Intermittent Cycle Extended Aeration System (ICEAS)was studied. The results showed that under the conditions that the operation cycle was 4.5 hours and the loading of sludge was 0.07 ~ 0.09 kg/(kg·d),the mass concentration of COD of the effluent water was 15.2mg/L ~ 42.2 mg/L, the removal rate of which reached 80%～88%; the mass concentration of BOD5 was 5.12mg/L～16.9mg/L, the removal rate of which reached 85% ～ 93%; the mass concentration of ammonia nitrogen was 4.5 mg/L ~ 7.5 mg/L, the removal rate of which was 60% ~ 70%; and that of phosphorus was 60% ～ 75%. These indicate that the ICEAS process is applicable for the treatment of municipal sewage in the southern part of China. |
