摘　　要：从我国城市生活污水处理现状中存在的一些问题出发,介绍了金华市推广使用沼气净化池的概况.通过2004至2005年间在5个沼气净化池出水口进行24次取样水质检测,并使用模糊数学方法对其污水处理效能作出评价.结果表明:沼气净化池出水中的BOD5和SS指标达到国家污水综合排放标注一级标准,CODCr达到国家二级排放标准,但NH3-N没有达到国家二级排放标准.今后应当从改良池型、优化微环境、改造微生物等方面着手,提高沼气净化池净化及产气功能,使这种分散处理污水的方式与集中处理方式共同作用,在大中城市的污水处理中发挥更大的作用.With the problems of treatment on the urban domestic sewage in our country, the municipal biogas digester in Jinhua city was investigated. 24 samplings were measured from the exports of biogas digesters in five locations during 2004 and 2005, as well as the fuzzy mathematics was used to evaluate the effect of the treatment. The results indicated that BOD and SS had met the first grade of national standard, and the COD had been up to the second grade of national standard, however NH3-N had not met the second national standard. In order to enhance the capability of the municipal biogas digester, some treatments such as improving the type of the pool, optimizing the micro-environment and reconstructing the microorganism should be taken into future actions. Further, the distribution wastewater treatment like municipal biogas digester should play a more important role in the system of city wastewater treatment to cooperate with the centralized ways together.
