صينى. 利用2006年沈阳畜禽养殖量数据,采用各类畜禽的粪便排泄系数,结合国内外研究,确定沈阳地区畜禽粪尿资源的计算参数和计算方法,在此基础上估算了沈阳地区畜禽粪尿产生量及其中污染物含量和畜禽粪便农田负荷,并对畜禽粪便污染风险进行评价。结果表明：2006年沈阳畜禽粪便年产生量已达2011.75万t,畜禽粪尿产生的BOD5、CODcr、NH3-N、TP、TN分别为52.26万t、59.58万t、12.92万t、5.68万t和13万t,畜禽粪便农田年负荷量平均为35.36・thm-2,污染风险指数平均为0.78,对周围环境具有高风险。该研究结果可为沈阳市农业生产布局和环境污染治理提供决策依据。[著者文摘]

Based on the statistical data in 2006,and according to the discharge rate of different livestocks,we calculated the production of animal manure,content of contaminants and pollution loading of livestocks,and assessed the risk of pollution from livestocks.The results indicated that the average yearly pollution loading of livestocks reached 2011.75 million tons in Shenyang, the mean amounts of BOD5,CODcr,NH3-N,TP,TN in animal manure were 52.26,59.58,12.92,5.68,13 million tons, respectively in 2006.The average yearly pollution loading of livestocks reached 35.36t・hm-2.It was found that the average risk index was 0.78,which indicated the risk level was high.This result can be applied to the agricultural layout and the environmental pollution control in Shenyang.
