六安市生活污水污染现状与治理对策探讨

Present Situation on the Life Polluted Water of Lu'an City and Inquiring into its Harness and Countermeasures

目前,六安市市区人口约35万,生活污水日产生量约6万吨。笔者通过调查发现:六安市排水管网不健全,且多为雨污合流制,生活污水纳管率仅为30%左右,城区绝大多数生活污水未经任何处理便直接排放,使城区的水体污染严重。在此基础上,笔者提出了合理的治理对策:加快排水管网的建设和城市生活污水的集中治理;加强生活污水的分散治理??城市生活污水沼气净化处理和生活污水用于农林业生产;合理利用地表水体的自净作用。

At present, there are about 350,000 citizens in the urban district of Lu＇an city, and the output of life polluted water per day is near to 60,000 tons. By investigating, researcher found out that the drain-pipe net in Lu＇an is not sound, polluted water to be let out was mostly mixed by rain water and life polluted water. The rate for life polluted water to be into pipes was about 30 per- cent. Most life polluted water in the urban district ran out directly without any disposals. Therefore, it made water body in the city polluted seriously. On such hasis, researcher puts forward some reasonable harness and countermeasures to such problem： to quicken the construction for the drain-pipe net, to concentrate on harness for the city life polluted water, to strengthen the scattered harness for life polluted water-to turn city life polluted water into marsh gas and purify it, to put life polluted water to the farming and planting use,to make reasonable use of self-purifying of water body on the surface of the earth.
