| 摘 要： | 为揭示阳宗海流域不同类型农村污水各污染指标的影响因素和分布特征,选取云南省的海晏村(传统型)和大营村(集镇型)的污水进行水样采集,通过方差分析研究其不同污染指标的浓度变化以及不同类型农村污水水质的差异性,并运用主成分分析法对污水进行水质评价。结果表明:阳宗海流域海晏村污水中的TN、COD均明显超过了城镇污水处理厂污染物排放二级标准,大营村的TP、TN、COD均明显超过了二级标准;pH值与氧化还原电位都是农村污水中污染物浓度的重要影响因子;两村的水质具有显著的差异性;传统型农村的水质比集镇型农村的要好,说明对阳宗海流域造成污染风险更大的是集镇型农村污水。

| Abstract: | In order to investigate the factors and distribution characteristics of pollution indicators of different types of rural sewage in the Yangzonghai Lake Basin, sewage water was collected from Haiyan(traditional type)and Daying(town type)villages in Yunnan Province, the concentration changes of different pollution indicators and the differences in sewage water quality were studied through analysis of variance, and the water quality was evaluated through principal component analysis. The results show that the concentrations of TN and COD in sewage from Haiyan Village and the concentrations of TP, TN, and COD in sewage from Daying Village significantly exceeded the grade II standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002). The pH value and oxidation-reduction potential were important factors that affect the pollutant concentration in rural sewage. The water quality of the two villages exhibited significant differences. The traditional-type rural water quality was better than the town-type, indicating that the town-type rural sewage will cause a higher risk of pollution in the Yangzonghai Lake Basin. |
