| 摘 要： | 采用了一种新的水处理技术微波辅助光催化(MW／UV／P25)降解4-氯酚(4CP)模拟废水。初始质量浓度为30mg/L的4CP在微波光催化下发生了降解，反应120min，4CP的降解率达到82．85％，Cl^-质量浓度增加值为7．95mg/L。4CP的降解率与溶液的pH、通气条件、紫外灯光照度等因素有关，外加H2O2氧化剂能够加速4CP的降解。微波辅助光催化降解4CP服从一级反应动力学方程。

| Abstract: | A new method microwave assisted UV electrodeless discharge lamp photocatalysis system(MW/UV/P25)is used for the treatment of 4CP simulated wastewater. The degradation rate of 4CP is up to 82.85% and the increase of concentration of Cl- is up to 7.95 mg/L after 120 min of reaction. The degradation efficiency is influenced by pH value of the suspensions, aerating N2 gas, varying light intensity etc, addition of H2O2 oxidant can improve the degradation rate. The degradation of 4CP under MW/UV/P25 accords with the first grade kinetics equation. |
