中文摘要：

与 Al13 种类和活跃氯化物的高内容， anelectrochemically 准备了 polyaiuminum 氯化物(E-PACI ) 介绍凝结和氧化的综合效率。E-PACI 的凝结性质是通过各种各样的水质量条件的罐测试调查的全身的联盟者。在 E-PACI 的活跃的氯能显著地由于活跃的氯 preoxidation 影响凝结行为，它能在水里改变有机物(OM ) 的表面费用特征。如果水拥有了相对低的 OM 内容(2 mg/L ) 和高坚硬(278 mg CaCO_3/L ) 的特征，活跃 chlorinepreoxidation 能改进 E-PACI 凝结效率。在有 OM (5 mg/L ) 的中等内容的水里，剂量将是一个关键因素决定在 E-PACI 的活跃的氯是否帮助了凝结过程。与碱的状况作比较，活跃的氯将在酸的区域在凝结过程上显示出更重要的影响。

英文摘要：

With high content of the Al13 species and the active chloride, an electrochemically prepared polyaluminum chloride （E-PACI） presents integrated efficiency of coagulation and oxidation. The coagulation properties of E-PACI were systemically investigated through jar tests in the various water quality conditions. The active chlorine in E-PACI can significantly influence the coagulation behavior due to the active chlorine preoxidation, which can change the surface charge characteristic of organic matter （OM） in water. The active chlorine preoxidation could improve the E-PACI coagulation efficiency if the water possessed the characteristics of relatively low OM content （2 mg/L） and high hardness （278 mg CaCO3/L）. In the water with medium content of OM （5 mg/L）, dosage would be a crucial factor to decide whether the active chlorine in E-PACI aided coagulation process or not. Comparing with alkaline condition active chlorine would show a more significant influence on the coagulation process in acidic region.
