中文摘要： 针对地表水体污染日益加剧及人们对饮用水要求的逐步升高，控制饮用水中消毒副产物（DBPs）的生成已成为给水处理的重要研究方向。本项目利用强化混凝技术处理有机微污染水样，测定了不同强化混凝条件下形成絮体的表面电性、粒度、分形情况、抗破碎性、沉降性等特性，揭示了水质条件以及水力条件对絮体特性影响，以及絮体特性对混凝工艺处理效果的影响。同时，根据对混凝后出水中消毒副产物（DBPs）生成趋势的测定，探讨了水质条件以及水力条件对DBP前驱物处理效果的影响。在上述研究的基础上，明确了絮体特性与DBP前驱物去除效果的综合关系。该研究将提高强化混凝处理有机微污染地表水的效果，增强强化混凝与与后续处理工艺联合使用的可操作性，并完善强化混凝理论体系，为安全供水提供理论基础和应用基础。

英文摘要： In recently, the pollution of surface water turns to be serious, and the drinking water quality is needed to be beter and beter. So, many researches has focussed the controling of disinfection by-productions (DBPs). In this study, water samples,which were polluted by micro organic matter,were treated by enhanced coagulation technology. The surface charge, size, fractacl dimension, breakage factor and sedimentation of flocs were determined at different coagulation condition in order to investigate the effect of water propertis and hydraulic power on the properties of flocs. The formation potential of disinfection by-productions (DBPs) was determined at different coagulation condition, and then the effect of water propertis and hydraulic power on the removal of DBPs precursors was investigated. According to the above results, the relationship between flocs properies and the removal of DBPs precursors was explorated. This relationship could improve the removal efficiency of micro organic matter, and enhanced the application of coagulation and following-up process. The results gotten in this study could perfect the enhanced coagulation theory system, and provide the theoretical and application basis of water supply.
