根据乌梁素海流域近年来社会经济概况,结合当地农业灌溉方式、畜牧养殖数量等数据,以总氮、总磷和COD为指标,计算每年不同面源污染源入湖污染物总量,分析了从21世纪以来不同污染源产生的污染物入湖量的变化趋势以及对湖泊污染贡献率大小... 根据乌梁素海流域近年来社会经济概况,结合当地农业灌溉方式、畜牧养殖数量等数据,以总氮、总磷和COD为指标,计算每年不同面源污染源入湖污染物总量,分析了从21世纪以来不同污染源产生的污染物入湖量的变化趋势以及对湖泊污染贡献率大小,结果显示COD和TN每年入湖量增长迅速,并且主要来源于农田面源污染,TP的主要污染源是畜牧养殖污染,污染物入湖量相对较少。 展开更多

The pollutants from the 15 rivers inflowing into Lake Taihu accounted for about 80% of the total amount of the pollutants inflowing into Lake Taihu. Therefore, overall treatment of the inflowing rivers of Taihu Lake is of great importance to the improvement of water environment in the valley and the eutrophication status in th lake. Firstly, the basic ideas, key taches and main methods for water pollution control of inflow rivers of Taihu Lake was put forward in this article, Basic on these theories, the pollutant source status in the comprehensive treatment zone of the 15 major inflow rivers was analysized, the countermeasures of pollution control and main regulation projects were introduced, and the total abatement of pollutants was predicted. With the implement of regulation projects, the number of rivers with water quality worse than Grade V among the 15 major inflow rivers had come from 9 to 3, and the eutrophication status of Taihu Lake had changed from medium level to light level. The overall treatment of the major inflow rivers of the Taihu Lake had achieved initial success. 展开更多
