摘要:近年来,分散居住区生活污水的处理越来越受到了人们的重视,并已经成为污水处理的重要部分。本论文介绍了现有的分散居住区生活污水处理技术,并通过检测处理设备进出水的COD、TP、TN、NH3-N、PH五个指标,重点研究了A/O+MBR工艺对分散居住区生活污水的处理能力。在对新场地区A/O+MBR处理设备3个进水点连续的检测中发现,在进水各指标变异系数超过0.5的情况下,91%的A/O+MBR处理设备出水依然可以达到城镇污水处理厂污染物排放二级标准。同时本文对航头地区工艺调试前后的进出水指标做了着重分析。最后对该工艺的运行进行了总结和展望。6097

The research of dispersed domestic sewage treatment
Abstract: In recent years, the treatment of small waste water has got more attention, and it has become an important part of sewage treatment. The page first introduces the existing treatment of small waste water, and regards the A/O+MBR as a key treatment to research on the basic of comparison with other treatment by testing the COD、TP、TN、NH3-N、PH index. In the continuous testing of Xinchang area’s three point we find that more than 91% of A/O+MBR equipment effluent can still reach the discharge standard of class two of urban sewage treatment plant pollutant., though the inlet water have the variation coefficient more than 0.5.And then analysis the removal rate and abnormal date of the treatment. Finally, this page summary and prospect the treatment.
