膜技术在中水回收中的应用（Application of membrane technology in reclaimed water recycling） The shortage of water resources, economic growth, population growth, water prices will lead to continuous improvement, therefore, vigorously develop the sewage reuse project, not only can save the limited water resources, alleviate the increasingly prominent water shortage, but also can reduce the discharge of sewage on the surrounding water, reduce pollution, improve human living the environment, but also save a lot of water resources fee. Wastewater reuse is an important measure to promote the coordinated development of economy, environment and society, and there are great business opportunities. Further processing of the regular planning of industrial wastewater treatment discharge by membrane separation technology can effectively remove organic matter in wastewater, color, hardness and most ions reached back for the production of water, on the one hand, on the other hand, reduce the discharge of waste water, saving water resources, reduce production costs. The water quality treated by this technology can meet the standard of water used in industrial production process, and can realize wastewater reuse. This will not only reduce the amount of wastewater discharge, but also reduce the amount of process water. It is of great significance for reducing environmental pollution, saving water resources and sustainable development of the industry as a whole. With the development of membrane separation technology, the improvement of membrane properties and the cost of membrane separation products, the reuse and reuse of wastewater by membrane technology will be one of the effective means of wastewater treatment. Technology introduction and application status The main system adopts the membrane technology which is popular in the world today. It is a separation technique of selective permeation of some components in aqueous solution by using a semipermeable membrane with the help of external press
