对奶牛、猪、禽规模养殖30个废水样品,分二次应用标准方法监测15个不同参数,并进行单项与综合指数评价分析.结果表明:不同畜禽养殖废水污染超标因子按污染指数大小排序存在差异性,猪氨氮＞总磷＞总氮＞砷＞铜＞CODcr＞铁＞锰;牛氨氮＞总氮＞铁＞CODcr＞总磷＞锰＞砷＞汞;禽总磷＞氨氮＞砷＞总氮＞CODcr＞铁＞锰.从中可见总磷、氨氮、砷、总氮、CODcr、铁和锰为污染共性因子,另有猪铜与牛汞个性因子,而且猪的污染超标因子污染指数最大.

30 waste water samples from different cattle farms,pig farms and poultry farms were collected to monitor 15 different parameters with standard mothod for twice and evaluate the single and comprehensive index.The result shows that there are differences among pollution exceeding standard factors of waste water by pollution indices order which was ammonia N＞total P＞total N＞As＞Cu＞CODcr＞Fe＞Mn in pig farms;NH4+＞TN＞Fe＞CODcr＞TP＞Mn＞As＞Hg,in cattle farms;and TP＞NH4+＞As＞TN＞CODcr＞Fe＞Mn in poultry farms,which shows that TP,AN,As,TN,CODcr,Fe and Mn are the common factors for pollution besides the individual factors of Cu in pig's and Hg in cattle's.In addition,the pollution index of pig's pollution exceeding standard factor is the biggest.
