摘要: 选取太湖流域典型地区9户农户(高、中、低收入水平各3户)作为研究对象,采用现场监测及入户调查的方法对农户生活污水各类污染物产排污系数进行系统定量研究。结果表明,收入水平对农户总生活污水中TN、NH4+-N、TP产污系数无显著影响,但对污水量、COD产污系数及总生活污水中各类污染物排污系数影响显著,均表现为高收入农户>中收入农户>低收入农户。厕所污水对污水污染总负荷贡献率极高,COD占67%以上,TN、NH4+-N、TP占84%以上,因此,厕所污水的利用与处理率是影响污染物排污系数的主导因素,而农业收入水平及化粪池类型则对这2种因素影响显著。

Abstract: A total of 9 farmer households(3 high,3 medium and 3 low in income level),typical of the Taihu Lake basin,were selected for studying quantitatively production and discharge coefficients of various pollutants in sewage from the rural areas of the basin through in-situ monitoring and indoor survey.It was found that income level had no significant influence on production coefficient of TN,NH4+-N and TP in total wastewater,but had on wastewater quantity,COD production coefficient and discharge coefficients of various kinds of pollutants in total wastewater,showing an order of high income household> medium income household > low income household in effect.The contribution of toilet wastewater to the total pollutant load was very high,reaching 67% or over in COD,and 84% or over in TN,NH+4-N and TP,so the utilization and treatment rates of toilet wastewater are the leading factors influencing discharge coefficient of pollutants,while agricultural income level and septic tank type have significant influence on the two factors.
