摘　　要：针对分散型社区、村镇点多面广的分布特点,研发一套光伏电能驱动的外置式MBR与纳滤膜组合的污水处理系统。对化粪池污水处理,按照GB 5749—2006《生活饮用水卫生标准》中54项指标检测,达到标准的22项,比标准高一个数量级的27项,比标准高2个数量级的5项。检测结果表明,该系统不仅适用于分散型社区、村镇生活污水处理,而且可用于分散型农村饮用水处理。根据运行及测试数据,对系统过程的物质转化、能量代谢进行了研究。研究结果表明,以清洁能源输入,将污水转化为2种可资源化利用的产品水,达到近零排放,处理系统工艺具有很好的生态化功能。According to the distribution characteristics of diffuse communities and villages, the wastewater treatment system combined with a suit of external MBR by photovohaic power and nanofiltration membrane. The fifty tbur indexes in GB 5749--2006 （standards for drinking water quality） of septic sewage after treatment were tested, and 22 indexes reached the standard, 27 indexes were an order of magnitude higher than standard, and 5 imtexes were two orders of magnitude higher than standard. The system was not only applicable to sewage treatment in diffuse communities and villages, but also to drinking water treatment in diffuse rural. According to operating and test data, material transformation process and energy metabolism in the system were studied. The treatment system has significant ecological function, and sewage could be reused as two kinds of product water ＇after treatment, with clean energy input and nearly zero emissions.
