摘  要:
利用2011年杞麓湖流域畜禽养殖量数据,采用排泄系数法估算该区域内畜禽养殖粪便产生量及其中污染物含量和耕地污染负荷,并对畜禽养殖进行环境风险评价。结果表明:2011年杞麓湖流域畜禽养殖产生粪尿总量22.34万t,CODcr、BOD5、NH3-N、TP及TN产生量分别为10504.8、8815.4、664.4、1242.4和2356.7 t,污染风险指数为1.03,畜禽粪便对环境污染较严重。

摘  要:
Based on the statistical data of livestock in the reaches of the Qilu Lake in 2011,and according to the discharge rate of livestock,we calculated the production of livestock manure,its pollutant content as well as pollution load of arable land,and assessed the environmental risk of livestock and poultry manure.The results indicated that the total amount of livestock and poultry manure in this region in 2011 was 223400 t,the productions of CODcr,BOD5,NH3-N,TP and TN were 10504.8 t,8815.4 t,664.4 t,1242.4 t and 2356.7 t respectively,and the pollution risk index was 1.03,so the pollution of livestock and poultry manure to the environment was serious.
