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。
In recent years, the domestic and international reviews on the development of treatment technology for drinking water produced by micro-polluted raw water are reviewed. In view of the status quo of surface water pollution, taking the domestic and international representative water purification technology as the main line, the research progresses of the pretreatment, advanced treatment and intensive coagulation treatment in the treatment of slightly polluted raw water are described Prospects. In particular, it is emphasized that among the many micro-polluted raw water strengthening treatment technologies, the use of high efficiency coagulant to carry out coagulation treatment is one of the most effective and economically feasible methods, and has become a research hotspot in the treatment of micro-polluted raw water. Furthermore, based on the introduction of commonly used coagulants in China, it is pointed out that the development of universal and special coagulants in combination with the regional and seasonal characteristics of surface water quality in our country can improve the micro-polluted raw water treatment Technology level, to protect the quality of drinking water supply provides an important way.
