摘要
为解决太湖平原河网地区农村生活污染入湖负荷的估算问题,以苏州市项城区望亭镇为研究区,使用问卷调查与实地观测相结合的方法,调查研究区内13个行政村中的41个自然村的农村生活污染情况,获得污染负荷产生并迁移入湖的相关信息.根据对调查结果的分析,估算研究区内生活污染负荷入湖系数.结果表明,太湖周边地区的农村生活污染入湖负荷主要由厕所排放和生活污水贡献;不同类型的农村生活源的入湖系数并不相同,厕所排污的入湖系数COD为0.3%～1.8%,TN为0.7%～3.0%,TP为0.6%～1.9%;生活污水的入湖系数COD为3.7%～27.5%,TN为8.1%～33.4%,TP为10.1%～31.2%;综合入湖系数COD为0.7%～4.8%,TN为0.9%～4.1%,TP为1.3%～4.0%.
Load of rural domestic pollution of Taihu lake was surveyed in Wangting town Xiangcheng district, Suzhou. Unit questionnaire and actual observation 41 villages from 13 townships were done in regards to source and migration of pollution. Loss rate into lake was estimated. Data showed that rural household toiletry and domestic sewage contributed dominantly, loss rate varied with types of pollutant. Rates of toilet were COD 0.3%-1.8%, TN 0. 7%-3.0%, TP 0.6%- 1.9% ; Rates of domestic sewage were COD 6.2%-28. 7%, TNS. 8%-33.5%, TP 8.0%-30. 5%. Overall comprehensive rates were found to be. COD, 0.7%-4.8%,TN,0.9%-4. 1%,TP,1.3%-4.0%.
