摘要
介绍了在安吉新农村建设中实际应用的两种高效生活污水处理技术PEZ和MSL。探讨了两种技术的结构特点、净化机理、技术特点及维护。最后对实际应用中进出水主要污染因子进行比对分析,发现PEZ和MSL生活污水处理系统长期运行后对COD_(Cr)、BOD_5、NH_3-N和TP的去除率仍然较高,且均能达到《城镇污水处理厂污染物排放标准》(GB18918-2002)中的一级标准。
This paper introduces the practical application of two kinds of high efficiency domestic sewage treatment technology PEZ and MSL in the construction of new countryside in An Ji.The structural characteristics,purification mechanism,technical characteristics and maintenance of the two kinds of technology are discussed.The comparison and analysis of the main pollution factors of inlet and outlet water are carried out. The result showed that the removal rates of COD_(Cr)、BOD_5、NH_3-N and TP in the MSL and PEZ sewage treatment system were still higher after long term operation and could achieve the first class standard of the ' Discharge standard of pollutants for municipal wastewater treatment plant '(GB 18918-2002).
