基于云南省第一次全国污染源普查数据,对云南省畜禽养殖业污染源分布及污染物产生和排放统计结果进行了分析,总结了目前云南省畜禽养殖业污染源的排污特点,为云南畜禽养殖污染防治提供科学依据与技术支持。畜禽养殖业产生的环境危害主要来源于畜禽粪便污染和尿液污水污染,其中的主要污染物有总氮(TN)、总磷(TP)、化学耗氧量(COD)、氨氮(NHs-N)、铜(Cu)、锌(Zn)等。2007年,云南省畜禽养殖业污染源污染物总氮排放量为5 818.56 t,总磷排放量为1 303.05 t,COD排放量为7.51万t,铜排放量21.97 t,锌排放量32.13 t,氨氮排放量2 413.93 t。结合云南畜牧业实际对污染防治提出了一些对策建议,以推动云南畜禽养殖业的可持续发展。
