摘要：随着社会经济的快速发展和人类生活水平的不断提高，现有的供水行业面临着前所未有的挑战。 一方面，生产与生活排放的污染物越来越多，导致全国多数城市地下水受到一定程度的点状和面状污染，且有逐年加重的趋势。日趋严重的水污染不仅降低了水体的使用功能，进一步加剧了水资源短缺的矛盾，对我国正在实施的可持续发展战略带来了严重影响，而且还严重威胁到城市居民的饮水安全和人民群众的健康。另一方面，在制药工程以及医疗领域上对纯水的需求也越来越大。因此如何开发新技术来净化生活用水，并提高纯化水的产能是目前社会所需。5307
近年来，由于微孔过滤膜性能不断提高，能够高效的处理自来水使之符合医疗用水的标准并且能够有效的处理生活污水，且生产成本越来越低。使之成为被广泛应用于处理医疗用水上以及饮用水的处理上。

Microporous membranes performance study of dealing with the water
Abstract:With the rapid development of social economy and people life level unceasing enhancement, the existing water supply industry is facing unprecedented challenges. Emissions of pollutants on the one hand, the production and life more and more, lead to the majority of urban groundwater by a certain degree of dot and pollution, and has a tendency to increase year by year. The use of the increasingly serious water pollution not only reduces the water functions, further aggravated the contradiction of water shortage, to our country is implementing the strategy of sustainable development has brought serious impact, but also a serious threat to urban residents of the drinking water safety and people's health. In pharmaceutical engineering and medical fields, on the other hand, the demand for water is becoming more and more big. So how to develop new technologies to purify water, and improve the capacity of purified water is needed by the society at present.
In recent years, due to the microporous membranes performance improving, can efficiently deal with tap water to make it conform to the standard medical water and can be effective treatment of sewage, and lower production cost. Making it widely used in processing medical water and drinking water treatment.
