摘 要:通过对奎濉河典型小流域进行实地调研,应用等标污染负荷法进行综合分析,结果表明:小流域内农业面源污染排放源中,生活源污染负荷率最大,达到57.32%,污染物排放总量达到75874.04 kg,其中COD为主要污染物,排放量达到39812.58 kg;养殖业污染负荷率为35.33%,达到18741.73 kg,种植业污染负荷率为7.35%。在3个评价因子COD,TN,TP中,以COD的污染负荷率最高,达77.17%;其次为TN,污染负荷率为16.83%;TP的污染负荷率为6.00%。农村生活和畜禽养殖污染是小流域内农业面源污染物主要来源,应是该地区农业面源污染防控的重点。Based on the field investigation of the typical small watershed of Kuisui River and the comprehensive analysis with the method of equal standard pollution load,we found that among the agricultural non-point source pollution sources in the small watershed,the pollution load rate of the domestic source was the largest,reaching to 57.32%,and the total amount of pollutants discharged reached to 75874.04 kg,in which COD was the main pollutant.The amount of pollutants discharged reached to 39812.58.The pollution load rate of aquaculture was 35.33%,reaching to 18741.73 kg,and that of planting was 7.35%.Among the three evaluation factors COD,TN and TP,COD had the highest pollution load rate,which was 77.17%;TN was ranked the second,which was 16.83%;TP had a pollution load rate of 6.00%.The pollution of rural life and livestock breeding was the main source of agricultural non-point source pollution in small watershed,which could be the key point of prevention and control of agricultural non-point source pollution in this area.
