改良型氧化沟工艺+深度治理技术处理城市污水

Municipal Sewage Treatment by Process of Improved Oxidation Ditch and Advanced Treatment Technology

以漯河市沙南城市污水处理厂为例,简要介绍了改良型氧化沟在处理城市污水中的工艺原理及运行特点,分析了其运行情况及效果,结果表明:主要出水指标CODCr,BOD5,SS,NH4+-N,TN,TP的去除率分别为92.62%,95.51%,97.82%,90.53%,72.95%,95.67%。出水水质完全达到了GB18918—2002《城镇污水处理厂污染物排放标准》表1一级标准A标准和中水回用要求。

Taking the urban sewage treatment plant in Luohe city as an example,process principle and operational characteristics of the improved oxidation ditch in municipal wastewater treatment were introduced simply and its operating conditions and treating effect were analyzed.The results show that removal rates of the main indicators of effluent,such as CODCr,BOD5,SS,NH4＋-N,TN and TP,are 92.62%,95.51%,97.82%,90.53%,72.95% and 95.67%,respectively.Effluent quality reached the standard of ＂Pollutant discharge standard of urban sewage treatment plant（GB18918-2002） Table 1 Standard A＂ and met the requirement of water reuse completely.
