农村生活污水处理设计 摘要：??目前，我国每年的废（污）水排放总量很大，其中大部分未经处理就直接排入江河湖泊，部分湖泊受到了不同程度的污染，有近60%的城市没有污水处理厂，农村地区的生活污水基本上未经过处理就直接排放，农村生活污水治理已经影响到 HYPERLINK /dangdai/ 现代新农村的建设。因此，农村环境污染越来越受到人们的关注。文章针对农村生活污水的实际情况，介绍了农村生活污水处理的一些技术与措施，期望能为我国农村污水治理分析的研究提供有益的借鉴作用。? 关键词： HYPERLINK /nongcun/ 农村生活污水；污水治理；农村建设 Abstract: At present, Chinas annual waste (sewage) water emissions greatly, most of them without any treatment directly into rivers and lakes, some lakes have been polluted to varying degrees, nearly 60% of the cities have no sewage treatment plant in rural areas, largely untreated sewage directly discharge sewage treatment in rural areas has affected the modern new rural construction. Thus, environmental pollution in rural areas more and more attention. Aiming at the actual situation of domestic sewage in rural areas, introducing sewage treatment in rural areas some of the technologies and measures, expectations for the analysis of Chinas sewage treatment in rural areas provide a useful reference for research.
