Abstract

: 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.

长三角地区饮用水安全保障对策

饮用水安全关系到国计民生。中国一贯高度重视保障饮用水安全。1978年中国改革开放以来，长三角地区经济发展活跃，人口密度高，水环境污染给该地区的饮用水安全带来了巨大的挑战。经过十多年的发展，长三角地区饮用水安全保障总体水平显著提高，有效促进了区域的协调可持续发展。然而，随着人们对水质和健康要求的不断提高，长三角特大城市群的饮用水安全保障工作面临着各种挑战。本文分析了长三角地区典型水源地的水质特征，总结了长三角地区城市饮水安全保障工作取得的成绩。从管理和技术两个维度和水源、水厂、二次供水三个方面提出完善生态补偿机制、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建议。这些策略可为长三角等重点区域保障饮用水安全和促进区域一体化提供参考。
