【摘要】 本文全面论述了水源有机污染的现状及对国民经济和人民身体健康造成的重大影响，指出对有机微污染源水进行处理的必要性和迫切性。并通过对国内外有机微污染水净化处理技术的分析，针对我国国情及常规水处理工艺中存在的问题，提出采用强化常规处理工艺处理微污染源水的必要性和现实意义。 高锰酸钾复合药剂强化混凝是目前采用的一种较为先进的水污染治理技术之一，本文在系统分析高锰酸钾复合药剂强化混凝机理、粉末活性炭强化混凝机理的基础上，进行了高锰酸钾复合药剂与粉末活性炭联用对黄河包头段两水厂有机微污染源水强化混凝的室内及生产性试验的应用研究。 针对两水厂不同的源水污染状况和现有的水处理工艺，通过室内和生产性试验，很好地解决了高锰酸钾复合药剂、粉末活性炭最佳投加点、投加量和投加方式的确定问题，并对两者联用的强化混凝效果与预氯化、单独高锰酸钾复合药剂预氧化进行了对比。试验研究结果表明：高锰酸钾复合药剂与粉末活性炭联用具有优异的强化混凝效能，能够完全取代预氯化并获得比其更佳的混凝效果；该项强化混凝工艺不仅技术上可行，而且具有明显的经济效益。 本文的试验研究为解决黄河水源日渐污染、水厂工艺落后与出水水质不断提高之间的矛盾、为包头市各水厂的更新改造和今后建新水厂提供了最佳的工艺选择和设计依据，并可为广大同行所借鉴，从而为实施水质深度处理、保证饮用水安全提供了行之有效的途径，具有广泛的社会效益和广阔的市场应用前景。更多还原

【Abstract】 This paper completely discussed the status quo of organic polluted water and the great influence of which on national economy and people’ s body health , pointed out that it was necessary and urgent to treat organic light polluted water. Through the analyses of domestic and foreign research of treatment to organic light polluted water and in point of condition of our country and problems of conventional water treatment technology, proposed the necessity and realistic signification to adopt enhanced treatment in organic light polluted water.So far composite potassium permanganate is one of the advanced water treatment technology in domestic. Based on the systematically analyzing the enhanced coagulation mechanism of composite potassium permanganate and powder activated carbon, the author carried on the laboratory and plant scale research on organic polluted Yellow River in Baotou two water factories with the combined process of composite potassium permanganate and powder activated carbon.In light of various pollution situations and various water treatment processes of two water factories, better solved the problems about throwing doses, throwing localities, throwing forms of composite potassium permanganate and powder activated carbon, as well as compared the enhanced coagulation efficacy of combined process of composite potassium permanganate and powder activated carbon, composite potassium permanganate pre-oxidation and pre-chlorination. The result of experiment shows: the combined process of composite potassium permanganate and powder activated carbon has excellent efficiency of enhanced coagulation and is more advanced than pre-chlorination, which can completely replace pre-chlorination and is not only feasible in technology but also remarkable in economic benefit.For settling the contradictions among gradually polluted yellow river water, falling behind technology of water factory and desired improvement of water quality, for renewing Baotou water factories and rebuilding new water factory, this experiment research provides the best process choice and design basis, which can be used as an example by person of the same profession, therefore creates fine condition for carrying out deeply water treatment and ensuring the safety of drinking water, and which has broad social returns and market applying prospect.更多还原
