节约用水与水资源再生回用技术的展望

Prospect of the Technolgy for Water Saving and water Resources Reuse

水是生命的源泉,工农业生产的血液,城市的命脉,也是人类社会与经济发展必不可少的重要资源。目前全球和我国水资源紧缺矛盾日益突出,节约用水技术与水的再利用技术就应运而生。本文重点介绍和讨论节约用水的理念和技术,包括工业、农业和生活用水的节水技术,以及水资源的再生利用技术,包括工业用水的再生利用、中水道技术、雨水的收集利用和除盐净水技术等。总之,节约用水与水的再利用决非权宜之计,而是今后水资源可持续利用的必然要求。因此,节约用水技术与水再利用技术还有很大的空间,值得我们水处理工作者去探讨和开发。

Water is the headspring of life,the blood of industry and agriculture,the lifeline of city and the necessary resources of social and economic development.Due to the scarcity of water resources in the world and our country,the technologies of water saving and water reuse emerge as the times require.The concept of watei saving,including the technologies of water saving in the industry,agriculture and living,and the technologies of water recycling,including the recycle of industrial water,the technology of wastewater reuse,the collection and use of rainwater,thd technology of water desalination and etc.,were presented and discussed intensively in this paper.In a word,water saving and water reuse is a makeshift in no case,and it is the inevitable request of sustainable use of water resources in the future.Therefore,the technologies of water saving and water reuse are worthy of being investigated and developed for researchers and workers in the industry of water treatment.
