摘要
饮用水安全关系国计民生,我国政府一直高度重视饮用水安全保障工作。改革开放以来,在经济发展活跃、人口高度密集的长三角地区,水体环境污染给饮用水安全保障带来了巨大挑战;经过十余年的发展,长三角饮用水安全保障水平整体显著提升,有力促进了区域协调可持续发展,然而人民群众对水质安全和健康的要求也在逐渐提高,长三角超大城市群饮用水安全保障工作依然面临诸多挑战。由此,本文以长三角典型水源水质特征为切入点,总结了城市饮用水安全保障工作实施成效,从管理和技术两个维度,以及水源、水厂、管网(二次供水)三个方面剖析了饮用水水质进一步提升的现状问题,提出了健全生态补偿机制、协同修订水质标准、发展绿色高效净化技术、创新供水管理模式等措施建议,以期为长三角超大城市群和其他重点区域的饮用水安全保障和区域一体化发展提供参考与借鉴。
Drinking water safety is related to national economy and people’s livelihood.China has always attached great importance to guaranteeing drinking water safety.Since China’s reform and opening up in 1978,water environmental pollution has brought great challenges to drinking water safety in the Yangtze River Delta region owing to active economic development and high population density in the region.After over ten years of development,the overall level for guaranteeing drinking water safety in the Yangtze River Delta region has significantly improved,effectively promoting the coordinated and sustainable development of the region.However,as people’s requirements for water quality and health gradually increase,work for guaranteeing drinking water safety in the megalopolis agglomeration of Yangtze River Delta faces various challenges.In this article,we analyze the water quality characteristics of typical water sources in the Yangtze River Delta region,and summarize the achievements in urban drinking water safety assurance of the region.Suggestions are proposed from two dimensions(i.e.,management and technology)and three aspects(i.e.,water source,water plant,and secondary water supply),including improving the ecological compensation mechanism,collaboratively revising water quality standards,developing green and efficient purification technologies,and innovating the water supply management model.These strategies can provide a reference for assuring drinking water safety and promoting regional integration in the Yangtze River Delta and other key regions.
