| 摘 要： | 提高城市污水处理中生物脱氮效率是当今国内外在污水处理中重点研究的课题。对现常用的A／O（缺氧／好氧）系统进行改进,从好氧装置出水口到厌氧装置之间增加一个回流装置,使在保持原有装置较高的CODCR和BOD5去除率的同时,使装置对氮的支除率有较大的提高。这对现有污水处理厂提高氮的去除效果有一定的实用意义。

| Abstract: | A/O (anaerobic/aerobic) system which is used widely at present has been improved. A backflowing device making water returned from outlet of the aerobic device to the anaerobic device is added to with the additional new device, the system maintains the original system's advantage of high rate of elimination CODcr and BOD-5, and enhances the rate of elimination nitrogen from 10.6% to 45.2%. So it has great value in usage to domestic sewage treatment plants. |
