| 摘 要： | 为探讨四川规模猪场主要污染物排放量、排放规律,本文选择成都附近的一家典型规模养殖场,按照春夏秋冬四个季节,对保育仔猪、育肥猪和繁殖母猪不同饲养阶段生猪的粪、尿量及其COD/TN/TP/铜/锌等污染物进行了周年监测。结果表明,规模猪场不同饲养阶段猪只的粪、尿产生量差异较大,保育仔猪、育肥猪和繁殖母猪每天每头的粪产生量分别为0.45、0.79和1.01 kg,尿产生量分别为1.65、3.47和5.60 kg,不同饲养阶段猪只的固体粪便含水率基本相同,变化范围在62.13%~68.16%,平均含水率65.27%;全氮、全磷、有机质含量基本一致,分别平均为2.68%,2.38%,55.91%;不同饲养阶段猪只的尿液pH值在6.88~7.41之间,偏碱性。育成猪尿液COD值、氨氮、凯氏氮较低,其次为繁殖母猪和保育猪。在此基础上,研究提出规模猪场主要污染物产污系数24个,排污系数18个,为构建四川生猪产排污系数测算方法、摸清全省乃至全国生猪粪污产生量、为国家制定节能减排相关指标等提供科学依据。

| Abstract: | A typical large scale pig farm located near Chengdu was chosen to explore the amounts of pollutant emissions and discharge regularity of the main pollutants on large scale pig farms in Sichuan province.Monitorings were made in different pig stages,namely nursling piglets,fattening pigs and breeding sows.The monitoring items included the amount of feces,urine and the contents of COD,TN,TP,copper,zinc and other pollutants.The results showed that the pig dung output for piglets,fattening pig and sows per head ... |
