摘要: 开发利用再生水具有巨大的社会经济价值,是实现可持续发展的重要环节。在美国加州,再生水利用已经成为其水资源的重要组成部分,具有详细的规划、系统地法律法规和完备的管理体系,走在了世界的前列。总结分析了加州再生水利用相关的法律法规与灌溉终端用户管理的一些经验,并对2个典型案例进行了剖析。科学的再生水利用规划、严格的源水水质控制方案、简单易操作的再生水水质标准、明确的管理体系以及完备的风险控制体系都是加州再生水成功利用的关键环节。基于对加州再生水利用经验的分析,提出了4条建议以推动我国再生水利用事业的发展。Abstract: For the water shortage regions, water reuse has many advantages and is the key step for sustainable development. In California, reclaimed water is extensively used and is an integral part of the water management plan. California is the leader for water reuse around the world for its systemic policies and laws as well as advanced management experiences. In this study, the water reuse experiences in California were summarized. The successful use of reclaimed water in California can be attributed to its scientific water planning, strict source control, simply and handleable reclaimed water quality, clear-cut responsibilities and detail risk management plans. Based on California’s water reuse experiences, four suggestions were put forward for water reuse in China.
