摘　　要： 在确定畜禽粪便年排放量估算方法和畜禽粪便排泄参数的基础上,根据2010年广州市番禺区10个镇的畜禽饲养量,估算了其畜禽养殖业粪便产生量并对由此产生的环境效应进行了评价。结果表明,2010年番禺区10个镇畜禽养殖业共产生458 687.38 t粪便,其中COD、BOD、NH3-N、TP和TN排放量分别高达14 134.74、12 461.22、930.98、1 262.22、2 791.16 t。不计水禽粪便排放量时,单位耕地面积上畜禽粪便猪粪当量平均负荷量为12.16 t/hm2,N、P平均负荷量为102.95 kg/hm2和40.31 kg/hm2。综合以上对应指标判断,畜禽粪便在沙湾镇、南村镇、化龙镇和石楼镇已产生较严重的环境问题。 The total domestic animal excrement and farmland loading amounts in 10 towns of Panyu were analysed based on the raising amount of domestic animal in 2010 through the estimation methods of yearly discharge amount of animal manure and the excretion parameter of animal manure, then the environmental effect produced from this was evaluated. The results showed that the production of animal manure of animal husbandry in 2010 in 10 towns of Panyu totaled 458 687,38 tons, in which there were COD, BOD, NH3-N, TP and TN 14 134.74 t, 12 461.22 t, 930.98 t, 1 262.22 t and 2 791.16 t respectively. When the amount of duck and goose feces were not included, the average farmland loading amounts of pig dropping was 12.16 t/hm2, and N 102.95 kg/hm2 and P 40.31 kg/hm2 respectively. Based on the above corresponding values, the animal husbandry had formed the pollutions in Shawan, Nancun, Hualong and Shilou.
