| 摘 要： | 研究高压脉冲放电与臭氧协同降解水中对氯苯酚影响因素的结果表明,250mg/L对氯苯酚处理30min后降解率达96%.臭氧浓度、自由基捕获剂以及电极之间的距离均可影响对氯苯酚的降解率.增加臭氧浓度及降低电极之间的距离,提高了对氯苯酚的降解率;加入自由基捕获剂,降低了对氯苯酚的降解率.

| Abstract: | The combination of high voltage pulse discharge and ozonation as an advanced oxidation technology was used to investigat the degradation of 4-chlorophenol (4-CP) in water. The factors that affect the rate of degradation were discussed. The 1.95×10-3 mol/L solutions of 4-CP were almost completely (96%) degraded after the discharge treatment of 30min. 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 20mm to 10mm. The presence of radical scavenger decreased the rate of 4-CP degradation. |
