微污染原水强化处理技术研究进展

Recent Advances in Enhanced Treatment Techniques for Tiny-polluted Raw Water

对近年来国内外针对由微污染原水制饮用水的处理技术发展状况进行了综述。针对地表水水质受污染的现状,以国内外有代表性的净水技术研究为主线,阐述了近年来预处理、深度处理和强化混凝等强化处理技术用于微污染原水处理的研究进展与发展前景。特别地强调了在众多微污染原水强化处理工艺技术中,使用高效混凝剂实施强化混凝处理是最为有效、经济可行的方法之一,已成为目前微污染原水处理技术的研究热点。进而,在对国内现有普遍使用的混凝药剂做介绍的基础上指出,结合我国地表水水质区域和季节特点,开发普适性和专用性高效混凝剂,可为提高我国微污染原水处理工艺水平,保障饮用水供水水质提供一条重要途径。

It was summarized that the research progress of treatment techniques for the potable water production from tiny-polluted raw-water.Based on the status of polluted surface water in China,the development of techniques for the tiny-polluted raw-water treatment like pre-treatment techniques,advanced techniques and enhanced coagulation,and so on,was reviewed on the basis of representative references.It was pointed out that among these treatment techniques for the tiny-polluted raw-water,the selection of effective coagulants for the specific raw water under the existing equipment condition of potable water plant,could significantly improve the produced water quality with the lowest cost.It was an economic method for the tiny-polluted raw water treatment and becomes a hot topic of research work in the area of raw water treatment.Furthermore,based on the widely used coagulants in the domestic industry combining with the regional and seasonal characteristics of the raw water,the development of universal and special coagulants with a high quality could improve significantly the techniques of our country in the tiny-polluted raw-water treatment and ensure the quality of potable water fundamentally.
