| 摘 要： | 通过对沣河降雨前后水质的监测,分析了沣河污染特征。结果表明:降雨形成的面源污染对沣河总氮负荷影响显著,硝氮和总氮在降雨过程中的变化有很好的相关性,硝态氮是沣河总氮污染的主要存在形式,其主要来自于农田和水土淋溶流失及城市地表径流的硝酸盐氮;非降雨时,农村排放的生活点源是引起沣河COD和氨氮水质污染的根本原因,降雨促使生活点源进入沣河,COD和氨氮在河流水质变化中有着很好的相关性,其污染主要来自于沣河流域城镇生活污水、工业废水、乡镇企业废水及高校生活污水。

| Abstract: | Through site monitoring water quality in Fenghe River before and after rain,the paper analyzed the water quality pollution characteristics.The results showed that non-point source pollution caused by rainfall affected TN markedly,change in nitrate nitrogen(NO3-) had good relativity with total nitrogen(TN) in the process of rainfall.NO3-is the main existence form of TN pollution in Fenghe River witch mainly come from farmland,soil and water leaching loss and urban runoff.Ammonia nitrogen(NH4+)and COD polluti... |
