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：农村生活污水；污水治理；农村建设Abstract:Atpresent,China'sannualwaste(sewage)wateremissionsgreatly,mostofthemwithoutanytreatmentdirectlyintoriversandlakes,somelakeshavebeenpollutedtovaryingdegrees,nearly60%ofthecitieshavenosewagetreatmentplantinruralareas,largelyuntreatedsewagedirectlydischargesewagetreatmentinruralareashasaffectedthemodernnewruralconstruction.Thus,environmentalpollutioninruralareasmoreandmoreattention.Aimingattheactualsituationofdomesticsewageinruralareas,introducingsewagetreatmentinruralareassomeofthetechnologiesandmeasures,expectationsfortheanalysisofChina'ssewagetreatmentinruralareasprovideausefulreferenceforresearch.Keywords:ruraldomesticsewage;sewagetreatment;ruraldevelopment目录任务书...................................................................................................................11前言....................................................................................................................31.1农村水环境污染现状..............................................................................31.2主要污染源..............................................................................................31.3污染的特点..............................................................................................41.3.1水质特点...............................................................................................41.3.2水量特征...............................................................................................41.3.3排放体制特征.......................................................................................51.4治理意义..................................................................................................52农村生活污水处理技术的选择........................................................................52.1污水处理技术路线..................................................................................52.2人工湿地处理系统..................................................................................62.3地下土壤渗滤净化系统..........................................................................72.4好氧生物处理系统..................................................................................82.5厌氧生物处理系统..................................................................................82.6生活污水净化池沼气..............................................................................92.7高效生物化粪池（SW型生活污水自净装置）...................................92.8处理技术的比较总结..............................................................................92.9厌氧发酵（沼气）—人工湿地............................................................103工艺设计与计算..............................................................................................123.1生活污水排放量的确定........................................................................123.2工艺流程与说明...
