为了全面了解秦皇岛市畜禽养殖污染现状,2013年对秦皇岛市8个区(县)的畜禽养殖情况进行了调查。结果表明:畜禽养殖污染物中化学需氧量(COD)、生化需氧量(BOD5)、氨氮(NH4+-N)、总氮(TN)和总磷(TP)排放量分别为1.59万t、1.40万t、0.14万t、0.14万t和0.05万t;青龙满族自治县、昌黎县、抚宁县和卢龙县等标污染负荷较大,占全市的96.1%,其中抚宁县化学需氧量、氨氮等标污染负荷最大,青龙满族自治县生化需氧量、总氮和总磷等标污染负荷最高。
In order to fully understand the status quo of livestock and poultry breeding pollution in Qinhuangdao City, in 2013, the situation of livestock and poultry farming in 8 districts (counties) of Qinhuangdao City was investigated. The results showed that the COD, BOD5, NH4 + -N, TN and TP emissions of livestock and poultry breeding were respectively 15,900 t , 140,000 t, 140,000 t, 140,000 t and 5,0000 t respectively. The standard pollution loads of Qinglong Manchu Autonomous County, Changli County, Funing County and Lulong County were large, accounting for 96.1% of the whole city, of which Funing County chemical oxygen demand , Ammonia nitrogen and other standard pollution load, Qinglong Manchu Autonomous County of biochemical oxygen demand, total nitrogen and total phosphorus and other standard pollution load highest.
