双膜法中水回用处理技术中试实验研究

Pilot-scale experimental study on water reuse treatment technology by double membrane method

淡水资源短缺问题不仅是我国还是全世界密切关注的问题,由于我国正处于飞速发展的重要阶段,水资源不足严重影响着经济的发展。为了解决水资源短缺的问题,近些年中水回用技术备受关注。本课题采用“浸没式超滤+反渗透”组合的双膜法对污水处理厂出厂水进行深度处理,不仅可以使回用水用于农业灌溉、绿化灌溉、回灌地下水、工业用水等,甚至还可以达到居民生活用水的标准,极大的解决了我国所面临水资源紧缺和生态环境不断恶化的问题。

The problem of shortage of freshwater resources is not only a matter of close concern to China but also to the world.Because of China is in an important stage of rapid development, the lack of water resources seriously affects the economic development. In order to solve the problem of water shortage, wastewater reuse technology has attracted much attention in recent years. In this project, the double-membrane method of “immersed ultrafiltration + reverse osmosis” is used to perform advanced treatment of the water from the sewage treatment plant. Not only can reuse water be used for agricultural irrigation, green irrigation, recharged groundwater, industrial water and so on. but also reach the standard of residential water use. Wastewater reuse greatly solved the problem that our country faces the shortage of water resources and the deteriorating ecological environment.
