| 摘 要： | 介绍了AOAO、SBR、MSBR、氧化沟、DEPHANOX等后置反硝化生物除磷脱氮工艺的流程及处理效果。该工艺由于聚磷微生物经过厌氧释磷后进人生化效率较高的好氧环境，其在厌氧池形成的吸磷动力可以充分地得到利用．故有较好的除磷效果。但碳源不足制约了系统的脱氮效果．在解决好反硝化脱氮碳源问题的条件下．该工艺也能取得较好的同时脱氮除磷效果，且操作简便，运行费用低．将有较好的应用前景。

| Abstract: | The flow and treatment effect of postposition biological denitrification processes such as Anaerobic-Oxic-Anoxic-Oxic, Sequencing Batch Reactor,Modified Sequencing Batch Reactor,Oxidation Ditch,DEPHANOX for nitrogen and phosphorus simultaneous removal are introduced. The process has a better effect on phosphorus removal because the phosphorus-removing bacteria comes to absorbing phosphorus in oxic zone after releasing phosphorus in anaerobic condition. The absorbing phosphorus power formed in anaerobic condition can be fully used. Insufficient carbon source debases the efficiency of nitrogen removal. If the carbon source for denitrification is resolved, the process can make better effect on simultaneous nutrients removal. Simple operation and low cost will make a good application prospect for it. |
