摘　　要：采用排泄系数法,分别计算了赵王河流经聊城市境内各县区以及整个赵王河流域2008年畜禽养殖污染物产生量、排放量和入河量。结果表明,2008年,赵王河流域畜禽养殖污染物产生量分别为CODCr20 789.82 t、氨氮1 225.88 t、总氮3 554.28 t、总磷1 730.85 t,排放量分别为CODCr 5 212.49 t、氨氮303.78 t、总氮1320.97t、总磷387.09t,入河量分别为CODCr521.25t、氨氮30.38t、总氮132.10t、总磷38.71t。在4种污染物中,CODCr的产生量、排放量、入河量所占比例最高,其次是总氮,再次是总磷,氨氮所占比例最小;4种污染物入河量与产生量呈正相关关系。With the method of excretion coefficients,pollutants loads,loads discharged with waste water and loads delivered into rivers of livestock and poultry breeding in different countries of Zhaowang basin in the city of Liaocheng were calculated.In 2008,pollutants loads of CODCr,NH3-N,TN,and TP contained in animal wastes were 20 789.82 t,1 225.88 t,3 554.28 t and 1 730.85 t respectively.Pollutants loads discharged with waste water of CODCr,NH3-N,TN,and TP reached 5 212.49 t,303.78 t,1 320.97 t and 387.09 t respectively.Pollutants loads delivered into rivers of CODCr,NH3-N,TN,and TP amounted to 521.25 t,30.38 t,132.10 t and 38.71 t respectively.Of the four pollutants,CODCr was the first in the percentages of pollutants loads contained in animal wastes,loads discharged with waste water and loads delivered into rivers,then was TN,TP was the third and the last one was NH3-N.The pollutants loads delivered into rivers had positive connections with the loads contained in animal wastes.
