水处理中膜分离技术种类及特性研究

Research on Types and Characteristics of Membrane Separation Technology in Water Treatment

随着时代进步,科技发展,中国的环境问题尤其是水污染日益严重,而饮用水质量紧密关系着人们的健康,所以保证饮用水的水质安全,是给水厂重要的使命与责任。膜分离技术由于兼有分离、浓缩、纯化和精制的功能,又有高效、节能、环保、分子级过滤及过滤过程简单、易于控制等特征具有自身独特的优势。给水厂的常规处理工艺已然不能满足水质的要求,深度处理虽能大大提高水质,但是国内逐渐发展起来的超滤技术在去除水中致病微生物方面效果显著。简要介绍膜分离技术的种类及在给水处理中的应用。

Along with the progress of the times, the development of science and technology, Chinas environmental problems especially the increasingly serious water pollution, and the quality of drinking water is closely related to peoples health.Ensuring the quality and safety of drinking water is a matter of great importance.Membrane separation technology has its own unique advantages, such as, the function of the separation, enrichment, purification and refining, and high efficiency, energy saving, environmental protection, molecular filtration, the filtration process is simple and easy to control.Conventional water treatment technology of water supply plant already cannot satisfy the requirement of water quality.The depth of processing can greatly improve the water quality, but the domestic ultrafiltration technology gradually developed effective in removing pathogenic microorganism in water.This paper briefly introduces the types of membrane separation technology and its application in water treatment.
