The combination of high voltage pulse discharge and ozonation as an advanced oxidation technology was used to investigate the degradation of 4-chlorophenol (4-CP) in water. The factors that affect the rate of degradation were discussed. The 1.95 x 10(-3) mol/L solutions of 4-CP were almost completely (96%) degraded after the discharge treatment of 30 min. The degradation of 4-CP was investigated as a function of the ozone concentration, radical scavenger and electrode distance. The rate of 4-CP degradation increases with an increase in ozone concentration and a decrease in the electrode distance from 20 mm to 10 mm. The presence of radical scavenger decreased the rate of 4-CP degradation.
采用高压脉冲放电与臭氧氧化相结合的高级氧化技术，对水中4-氯酚（4-CP）的降解情况进行了研究。探讨了影响降解速率的因素。4-CP浓度为1.95×10⁻³mol/L的溶液在放电处理30分钟后几乎完全（96%）降解。研究了4-CP降解与臭氧浓度、自由基清除剂和电极间距的关系。4-CP的降解速率随臭氧浓度的增加以及电极间距从20毫米减小到10毫米而增加。自由基清除剂的存在降低了4-CP的降解速率。
