摘要
针对铁岭市亮子河流域水环境质量问题,开展污染源调查,采用系数法估算流域内污染源贡献占比,结果表明,亮子河流域主要污染源为畜禽养殖粪污,其COD和氨氮负荷占全流域总污染负荷的75.22%和70.74%。同时,根据流域整体污染状况,提出污染治理对策。
Aiming at the water environment quality problem of Liangzihe river basin in Tieling city,a pollution source survey was conducted,and the coefficient method was used to estimate the contribution proportion of pollution sources in the watershed.The results show that the main pollution source in Liangzihe river basin is manure from livestock and poultry breeding,and its COD and ammonia nitrogen load account for 75.22%and 70.74%of the total pollution load of the whole basin.At the same time,according to the overall pollution situation of the river basin,put forward pollution control measures.
