摘　　要：以滦河水为处理对象,对天津市泰达自来水厂预臭氧化一紫外/氯联合消毒工艺的运行效果进行分析。分别对各处理单元出水中的藻类、叶绿素a、pH值、浊度、DOC和UV_(254)进行测定,结果表明:整个工艺运行平稳,出水水质较好。原水经过预臭氧化处理后,藻类数量和叶绿素a浓度均有降低,预臭氧化单元对藻类和叶绿素a的平均去除率分别为38.26%和36.25%;整个工艺对藻类和叶绿素a的平均去除率分别可达75.55%和99.01%。此外,预臭氧化对原水的pH值及去除浊度、UV_(254)和DOC也有一定的影响。预臭氧化可有效降低浊度和UV_(254)值,但对去除DOC的影响不明显。The operation eftects of preozonation - UV/chlorine disinfection for treatment of Luan River water in Tianjin TEDA Water Treatment Plant were analyzed. The algae, chlorophyll a, pH, turbidity, DOC and UV2s4 values in outflow from the treatment units were determined. The results show that the whole process runs smoothly, and the water quality is good. Preozonation can significantly reduce algae and chlorophyll a, and the average removal rates are 38.26% and 36.25%. The average removal rates of algae and chlorophyll a are up to 75.55% and 99.01% after the whole process. In addition, pH, turbidity, UV：54 and DOC in raw water also have some changes after treated by preozonation. Preozonation can effectively reduce turbidity and UV：54 values, but has little effect on the removal of DOC.
