摘要
内蒙古乌梁素海已成为我国寒旱区富营养化最为严重的湖泊,为弄清乌梁素海所面临的污染负荷情况,在大量实测数据和调查数据的基础上,对乌梁素海的污染源进行了详细的计算分析。结果表明:乌梁素海的污染源主要来自3个方面,分别是农田排水、工业废水和生活污染。其中,农业排水中总磷对乌梁素海的贡献率超过了30%,总氮的贡献率接近50%,COD的贡献率达到了65%。可见,农田排水对乌梁素海污染负荷的贡献率最大。为乌梁素海源头治理提供了一定的参考依据。
Wuliangsuhai Lake is the most serious eutrophication lake which is located in cold and arid regions of China.To clarify the situation of pollution and based on a large number of experimental data and investigation data,the result shows that there are three main sources of pollution in Wuliangsuhai Lake： agricultural drainage,industrial waste water and domestic pollution,in which contribution rate of TP in agricultural drainage is more than 30%,contribution rate of TN in agricultural drainage is close to 50%,and contribution rate of COD in agricultural drainage reaches 65% in Wuliangsuhai Lake.This paper serves as a reference for source control in Wuliangsuhai Lake.
