武当山剑河流域水污染源解析

通过实地调查、现场监测和实验室分析等方法,研究了剑河流域水污染源现状。结果表明:剑河流域各污染源每年排放的COD、TN、TP、NH3-N的实物总量分别为1114.84、219.43、21.84、145.33t,其中点源中COD、TN、TP、NH3-N的排放量依次为876.1、140.98、9.51、27.72t;面源中COD、TN、TP、NH3-N排放量分别为238.74、78.45、12.33、44.63t;各污染物实际入河量依次为COD 439.5、TN 123.76、TP13.91、NH3-N 76.38t;城镇生活污水对COD、TN、NH3-N负荷量的贡献率最高,畜禽养殖污水对TP负荷量的贡献率最高。

Water Source Apportionment of Pollutions in Jianhe River Valley of WuDang Mountain

The situation on water pollutant in Jianhe River valley was researched by using the methods which includes field investigation,site monitoring,analysis in the laboratory,etc.The results showed that chemical oxygen demand,total nitrogen,total phosphorus and ammonia nitrogen loads in Jianhe River valley respectively were 1114.84,219.43,21.84,145.33 t/a,chemical oxygen demand,total nitrogen,total phosphorus and ammonia nitrogen respectively were 876.1,140.98,9.51,27.72 t/a in point source and 238.74,78.45,12.33,44.63 t/a in non-point source.The actual quantity of chemical oxygen demand,total nitrogen,total phosphorus and ammonia nitrogen that inflow into Jianhe River were 439.5,123.76,13.91,76.38 t/a respectively.The highest contribution to pollution load in chemical oxygen demand,total nitrogen and ammonia nitrogen was wastewater and garbage from urban residents and the highest contribution for total phosphorus load was livestock and poultry breeding.
