摘　　要：根据大连金州新区畜禽养殖业的发展,计算了全区养殖畜禽的粪便量、污染物产生量,分析了畜禽粪便的污染风险,并计算了畜禽粪便产沼气的潜力。研究结果表明:大连金州新区2012年畜禽粪便产生总量约为37.25万t/年,可产生污染物COD 62158.9 t/年、氨氮1 477.8 t/年,对河流水质有一定影响。而畜禽粪便的沼气潜力较大,可为当地农户提供7 326.5万m3清洁能源。In this study,according to the livestock and poultry breeding industry development of Jinzhou New District in Dalian City,fecal amount and contaminant product from livestock and poultry breeding in the whole district was calculated,risk assessment of livestock and poultry fecal was discussed,and the potential of marsh gas product using livestock and poultry fecal was also analyzed.The conclusion of this paper indicates that the total fecal amount from livestock and poultry breeding in 2012 was 372.5 k t/a,which can product contami-nant COD 62 158.9 t/a,ammonia nitrogen 1 477.8 t/a,and this can influence the water quality in rivers. Nevertheless there is great potential of marsh gas product using livestock and poultry fecal,and it can product clean energy 73.265 million m3 for the local peasant household.
