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。
Thirty wastewater samples were cultured on the scale of dairy cattle, pigs and poultry. Fifteen different parameters were monitored by secondary standard methods, and the individual and comprehensive indexes were evaluated and analyzed. The results showed that there was a difference in the order of pollution index according to the index of pollution index. Among them, ammonia nitrogen> total phosphorus> total nitrogen> arsenic> copper> CODcr> iron> manganese> bovine ammonia nitrogen> total nitrogen> iron> CODcr> Phosphorus> manganese> arsenic> mercury; poultry phosphorus> ammonia nitrogen> arsenic> total nitrogen> CODcr> iron> manganese. It can be seen that total phosphorus, ammonia nitrogen, arsenic, total nitrogen, CODcr, iron and manganese are common factors of pollution, and pigs with individual factors of mercury and mercury, and the pollution index of pig exceeded the maximum.
