【摘要】：我国的淡水资源人均占有量极为匮乏。然而,随着世界经济的飞速发展、城市化历程的加快、人口的增加、人民生活水平的逐步提升,不仅对淡水资源的需求量提出新的考验,而且更重要的饮用水安全是关乎百姓身体健康、民生国计头等大事。受改革开放影响,苏州的人口数量迅猛增长,上游的来水水质、当地工业产生废水及生活所排放污水均不同程度地影响着地表水环境,地表水水质每况愈下,饮用水水源地的保护工作显得极为重要。本文主要通过调查和分析苏州市区4个集中式饮用水水源地的相关资料和水质数据,得出饮用水源水质总体保持稳定,反映富营养化程度的总氮指标总体未有明显改善,呈高位波动变化的综合评价。结合对饮用水源地污染状况的调查与分析,查找原因主要有上游来水水质的影响、农业非点源和农村生活污染的影响和底泥的影响,在入湖河道进行总氮控制、农业非点源和农村生活污染治理和提高污水厂总氮处理效率等方面提出相应对策和建议,为后续的饮用水源地保护或其他饮用水源地保护工作提供一定的参考。
[Abstract]:The per capita possession of freshwater resources in China is extremely scarce. However, with the rapid development of the world economy, the accelerated course of urbanization, the increase of population and the gradual improvement of people's living standard, not only the demand for fresh water resources has been put to a new test. And more important drinking water safety is related to the health of the people, the national affairs of the top priority. Under the influence of reform and opening up, the population of Suzhou has increased rapidly. The water quality of the upstream water, the wastewater produced by local industry and the sewage discharged from the daily life have affected the surface water environment to some extent, and the surface water quality has deteriorated. The protection of drinking water sources is very important. Based on the investigation and analysis of the relevant data and water quality data of four centralized drinking water sources in Suzhou, this paper concludes that the water quality of drinking water source remains stable, and the total nitrogen index reflecting eutrophication has not been improved significantly. Comprehensive evaluation with high fluctuation. Combined with the investigation and analysis of the pollution situation of drinking water source, the main reasons are the influence of upstream water quality, the impact of agricultural non-point source and rural life pollution and the influence of sediment, and the total nitrogen control in the river channel into the lake. In order to provide some reference for the protection of drinking water source or other drinking water sources, the corresponding countermeasures and suggestions are put forward in the aspects of agricultural non-point source and rural life pollution treatment and improving the efficiency of total nitrogen treatment of wastewater treatment plant.
