摘　　要：为进一步提高饮用水水质，通过系统研究筛选混凝剂及优化混凝过程来达到高效去除污染物，以提供经济合理的水处理工艺途径．结果表明：新型药剂具有显著提高出水水质的性能，改善了沉淀后水体颗粒物的粒度分布特征，提高了过滤效率．同时表现出明显优越的去除有机物能力。传统工艺TOC去除大约在9％～11％，而新型药剂则可以达到17％～20％．应用树脂分离分级对不同有机物表征的结果也得到进一步证实．原水的TTHMFP为20．98μg／L，而原有工艺为11．01μg／L，使用新药剂后仅为6．40μg／L．使用新药可以明显节约成本，具有显著的经济效益，同时降低生产工艺的复杂性．To meet the requirement of improved water quality, the economic water treatment process could be achieved by systematic coagulant selection and optimization of coagulation process. The experimental results show that the new coagulant developed has significantly improved the water quality, with marked modification of the particle size distribution feature after sediment and improved filtration efficiency. The organic removal ability, as shown by low TOC and UV254 in the finished water, is also significantly improved and also verified by using resin absorption characterization method. The TTHMFP for the source water is 20.98μg/L and 11. 01μg/L for the traditional process. By using the new coagulant the TTHMFP is further decreased to 6.40μg/L. With application of the new coagulant, the treatment costs are significantly decreased with further improved and simplified treatment process.
