| 摘 要： | 基于反硝化聚磷理论,结合MBR工艺的优点,在传统A2O工艺的基础上提出新型并联式同步脱氮除磷工艺。工艺解决了传统工艺中的碳源不足、硝酸盐氮供需矛盾等问题;通过省去沉淀池,节约了占地面积。针对常规城市污水,研究了不同工艺条件对处理效果的影响。结果表明,当污泥体积回流比为50%,内体积回流比为100%时具有较好的去除效果,COD、NH4+-N、TP和TN去除率分别达到了90%、99%、94.4%和67%。 |

| Abstract: | This paper describes the theory of denitrifying phosphorus,combining with the advantages of MBR technology,I proposed a new parallel synchronization nitrogen and phosphorus removal process which based on the traditional A2O process.It resolved the problem of insufficient carbon source and the contradictions of nitrate supply and demand in the traditional process.By eliminating the settling tank,small footprint were needed.For conventional municipal sewage,it studied the effects of treatment efficiency in different process condition.The experimental results showed that when the sludge return ratio was 50%,the reflux ratio was 100%,this process achieved a good nitrogen and phosphorus removal efficiency: COD,ammonia nitrogen,TP and TN removal rates reached 90%,99%,94.4% and 67%,respectively. |
| Keywords: | A2O denitrifying phosphorus MBR simultaneous nitrogen and phosphorus |
