强化混凝技术去除水中有机物的研究进展

强化混凝技术是指通过增加混凝剂投加量、投加助凝剂、使用新型高效混凝剂、调整pH值及进行氧化预处理从而提高常规混凝处理中有机物的去除效果,最大限度地去除消毒副产物的前驱物,是一种经济有效的深度处理技术,无需投入大量的资金.系统介绍了强化混凝技术在有机物去除方面研究与实践所取得的最新成果,指出了进一步研究中亟需解决的问题,以期为我国强化混凝技术的研究与应用提供有益的借鉴.;Enhanced Coagulation(EC) is the optimum of coagulation process by increasing the dosage of coagulants,utilizing flocculants,developing new coagulants,controlling pH and enforcing Pre-oxidation in order to increase the removal of objective pollutants and decrease the formation of by-products(DBPFP) in water.It is one of the most economical and effective advanced water treatment technologies which can effectively remove organic matters without large monetary investment.The current research and application of enhanced coagulation are summarized and some questions to be improved are put forward for further study in order to offer valuable suggestions for the research in China
