摘要
由于全球水资源的持续紧张,如何更加高效地利用再生水成为亟需解决的问题。近年来再生水饮用回用成为国际研究热点,其具有无需在城市内单独新建配水管网,同时又能提高再生水利用效率等优点。目前,再生水饮用回用在水资源长期短缺的国家已有实际应用,但其尚未在我国引起广泛的关注与重视,也无应用案例。在简要回顾全球再生水饮用回用概况的基础上,分别选取国外间接饮用回用和直接饮用回用的典型案例,对其主要工艺与出水水质、风险管控措施、成本与能耗进行剖析,在此基础上对我国再生水饮用回用提出思考与启示,以期对再生水饮用回用在我国的发展起到借鉴作用。
Due to the continuous shortage of global water resources,how to use the reclaimed water more efficiently has become an urgent problem to be solved.In recent years,potable reuse of reclaimed water has become an international research hotspot.It has the advantages of no need to build a new distribution network in the city,and can improve the utilization efficiency of reclaimed water.At present,potable reuse of reclaimed water has been practically applied in countries with long-term shortage of water resources,but it has not attracted widespread attention and taken into account in China,and there are no application cases.Based on a brief review of the global overview of potable reuse of reclaimed water,the typical cases of indirect potable reuse and direct potable reuse of reclaimed water in foreign countries were selected,and the main processes and effluent quality,risk control measures,cost and energy consumption were analyzed.On this basis,thinking and enlightenment for potable reuse in China are proposed,which may provide a reference for the development of potable reuse in China.
