摘　　要：通过进行预臭氧化-紫外/氯工艺处理低温低浊期水源的生产性试验,分别对各处理单元出水pH、浊度、DOC和UV254进行了测定。结果表明,在低温低浊期,整套工艺对浊度、DOC和UV254的平均去除率分别为93.83%、29.38%和57.20%。此外,预臭氧化单元对pH及去除浊度、DOC和UV254也有一定的影响。预臭氧化单元可有效降低UV254,但对浊度和DOC的去除效果不明显。A full-scale study was performed on the process of preozonation-UV/chlorine disinfection for treatment of low temperature and low turbidity water, and pH, turbidity, DOC and UV254 values in outflow from the treatment units were determined. The results show that during the low temperature and low turbidity period, the average removal rates of turbidity, DOC and UV254 for the whole process were 93.83%, 29.38% and 57.20%, respectively. In addition, preozonation unit have certain effect on pH, turbidity, DOC and UV254 in raw water. Preozonation unit can effectively reduced UV~ values, but had little effect on the removal rates of turbidity and DOC.
