世界卫生组织《再生水饮用回用:安全饮用水生产指南》解读

Interpretation of Potable reuse guidance for producing safe drinking water by WHO

面对世界各地日益增长的再生水饮用回用研究、实践和发展需求,世界卫生组织(WHO)于2017年8月首次发布了《再生水饮用回用:安全饮用水生产指南》,旨在为各国开展再生水饮用回用规划、设计、运行、管理和系统评价等工作提供技术指导,逐步引导并规范再生水饮用回用的广泛、深入和可持续发展。指南从保障公众健康安全的角度,提出了再生水饮用回用管理原则、系统评价、管理方法及监管要求,强调了水回用系统全流程控制、多屏障水质安全保障等措施,并讨论了现有知识鸿沟和今后研究方向,为我国水回用行业开拓和扩展再生水利用途径提供重要指导和借鉴。

Faced with increasing research,practice and development demand on potable water reuse,the World Health Organization（WHO）has first issued the Potable reuse guidance for producing safe drinking water in august 2017.The guideline aims to provide technological guidance for the planning,design,operation,management and evaluation of potable reuse schemes,and encourage and regulate potable reuse into extensive,thorough and sustainable development.From the standpoint of public health safety ensurance,the guideline proposes potable reuse management principles,system evaluation and management methods and surveillance requirements,emphasizes the control measures such as whole process control and multiple barrier approach,and discusses current knowledge gaps and future research directions.This guideline can provide valuable guidance and advice for the exploitation and development of reclaimed water applicationsin China.
