摘　　要：选取西宁市4个地区不同收入水平的12户典型农户,分析其生活污水构成和水质特征,并对COD、NH3-N、TP、TN等污染物负荷进行了测算。结果表明,西宁市农村居民生活污水为灰水;COD、NH3-N、TP、TN的质量浓度平均值分别为523.34、4.70、4.56、18.68mg/L,呈现出夏季浓度较低,冬季浓度较高的规律;人均日产COD、NH3-N、TP、TN的负荷分别为18.95、0.173、0.166、0.690 g,污染物负荷远低于城市。12 typical rural households with different income levels in four rural areas of Xining City were investigated,and the composition of domestic wastewater and its wastewater quality were analyzed,the pollution loads of some relevant parameters,including COD,NH3-N,TP and TN were estimated.The results showed that the wastewater flows in Xining rural areas were grey water.The mean concentration of COD,NH3-N,TP and TN were 523.34,4.70,4.56 and 18.68 mg/L respectively.The concentrations of these parameters had an obvious change with season,namely lower in the summer and higher in the winter.The daily pollution loads per capita of rural domestic wastewater for COD,NH3-N,TP and TN were 18.95,0.173,0.166 and 0.690 g in the order mentioned,which were much lower than that of municipal domestic sewage.
