摘　　要：以引滦原水、引江原水和引滦引江掺混原水为研究对象,将天津某净水厂强化集成工艺近三年的实际生产运行数据,特别是高温高藻期的数据进行对比分析。结果表明,预氧化—上向流脉冲澄清—主加氯消毒的强化集成工艺可以适应原水水质的变化,对引滦原水、引江原水和引滦引江掺混原水浊度、CODMn的去除率分别高达94.90%和64%以上,出厂水浊度和CODMn最低分别达到0.13 NTU和0.29 mg/L,藻类均未检出,三卤甲烷、卤乙酸、甲醛、溴酸盐等消毒副产物指标也远低于国标限值,能够保证出厂水的水质安全达标。Actual operational data of an enhanced integrated process of a water plant treating different raw water from the Yangtze River, Luan River and their mixture in Tianjin in recent three years, especially the data of high temperature and high algae period, were compared and analyzed. The enhanced integrated process of pre-oxidation, pulse clarifying and chlorine disinfection could adapt to the change of raw water quality. The removal efficiencies of turbidity and CODMn in three raw waters were more than 94.90% and 64%, respectively. The lowest turbidity and CODMn in the effluent were 0.13 NTU and 0.29 mg/L, respectively, and algae were not detected. Disinfection by-products indexes such as THMs, HAAs, formaldehyde and bromate were all far below the maximum contaminant levels of national standard limits, indicating that the process can ensure the safety of the effluent water quality.
