摘要
本文结合郑州市五龙口污水处理厂工程,介绍了改良型氧化沟在处理城市污水中的构成、工艺原理及运行特点,分析了其运行情况及效果,主要出水指标BOD5、COD、SS、NH3-N、TP的去除率分别为93%、87%、93%、97%、64%。水质达到国家排放标准。
The composition, technological principle and operational characteristics of a improved oxidation ditch device for municipal sewage treatment are introduced by integration with the technological process of a sewage treatment plant in the paper, its operating conditions and treating effect are analysed; the removal rates of main effluent indexes, such as BOD, COD, SS, NH3-N and TP content, reached to 90%, 87%, 93%, 97% and 64% respectively, reaching the national discharge standard.
