摘要: 株树桥水库饮用水水源地作为国家重要湖库型饮用水水源地,是长沙市区的重要备用水源。为了评价株树桥水库水资源建设和保护工作情况,以内梅罗污染指数(Ip)来评价株树桥水库水源地综合治理前后的水质状况,并进一步对其湖库营养化的整体情况进行分析。结果表明,与治理前2011年比较,2017年至2019年株树桥水库Ip值逐年平稳下降,CODMn、TP和NH3-N浓度也逐年下降。作为典型的湖库型饮用水水源地,水资源综合治理有效的控制了入湖排污,促进了库区水生态环境修复,水质总体上趋于良性发展。
Abstract: As an important drinking water source for Changsha city, the water quality before and after the comprehensive treatment of the Zhoushuqiao reservoir was evaluated by the Nemerow Pollution Index (Ip), and the eutrophication of lakes and reservoirs were also evaluated. The results show the Ip value of the Zhoushuqiao reservoir in 2017 to 2019 declined steadily compared with the 2011, while the concentration of CODMn, TP and NH3-N were falling. The emissions was effectively reduced into the typical drinking water source in lake reservoirs through the comprehensive treatment, the water eco-system restoration is increased significantly, the change of water quality tending to benign development has realized generally.
