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-氯苯酚（4-CP）进行降解研究。讨论了影响降解速率的因素。1.95 × 10（-3）mol/L的4-CP溶液经30 min放电处理后，降解率可达96%，并研究了臭氧浓度、自由基清除剂和电极间距对4-CP降解的影响。4-CP的降解速率随着臭氧浓度的增加而增加，电极距离从20 mm减小到10 mm。自由基清除剂的存在降低了4-CP的降解速率。
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.
