摘　　要：通过对畜禽粪便年排放量的估算方法和畜禽粪便排泄参数的确定,估算了天津市畜禽养殖业粪便产生量并对由此产生的能源与环境效应进行了评价。结果表明,2006~2014年天津市畜禽粪便总量、COD总产量、氮总产量、磷总产量都呈现增长趋势,2014年全市畜禽粪便总量达到约940×10~4 t。天津市耕地总磷负荷和总氮负荷呈现增长趋势,其中耕地总磷负荷自2012年来超过粪肥年施氮限量标准,其中耕地总磷负荷自2014年来超过粪肥年施磷限量标准。2006~2014年天津市的畜禽粪便沼气资源潜力增长趋势,2014年天津市的沼气资源潜力约为4.12×10~8 Nm^3。相当于当年天津市天然气消费量的约6%。The production amount of animal manure of cultivation industry in Tianjin was estimated through the estimation methods of yearly discharge amount of animal manure and the determination of excretion parameter of animal manure,and the energy and environmental effect produced from it was evaluated.From the year 2006 to 2014,the production of poultry manure,COD,nitrogen and phosphorus in Tianjin increased.The production of animal manure of this industry in the year 2014 in Tianjin totaled 9.4million tons.And the average cropland load of animal manure's N,P pure nutrient increased during these years.The average cropland load of animal manure's N pure nutrient exceeded standard from 2012,and the average cropland load of animal manure's P pure nutrient exceeded standard from 2014.From 2006 to 2014,biogas potential production in Tianjin increased.The biogas potential production in the year 2014 in Tianjin totaled 412.29 million tons,which was 6% of natural gas consumption in Tianjin in this year.
