| 摘 要： | 以紫外光源为主要依托,变换反应器中的不同工艺条件,分别对紫外光、臭氧和紫外/臭氧三种不同于工艺条件对水中污染物2,4-二氯酚(2 ,4-DCP)的降解规律进行研究.结果表明,UV/O3复合对2,4-DCP的降解较UV、O3单独作用效果好;溶液的酸碱度影响UV/O3对2 ,4-DCP的降解;此外,溶液中含有细菌时,E. coli的杀灭效果仍表现为UV/O3＞O3＞UV.细菌的杀灭和2,4-DCP的降解均消耗羟基自由基,形成竞争反应,从而影响到2,4-DCP的降解效果.

| Abstract: | A new type UV reactor was used for the research on the degradation of 2,4-DCP.The results were obtained at the following variable conditions:UV-radiation only,O_3 applied individually by the reactor,and with a combination of UV/O_3.The results showed that the degradation effects of 2,4-DCP achieved by using UV/O_3 was higher than other two indvidual approaches,and the degradation efficiency appeared to be different when the pH of solutions was alternated.Furthermore,the experiments of the degradation of 2,4-DCP were conducted under the condition of the solution containing bacteria and the result showed the highest disinfection effect of UV/O_3. |
