| 摘 要： | 通过配置一定浓度的含二氯甲烷的有机废气，考察了UV、H2O2和Fenton等单一及组合氧化工艺氧化降解二氯甲烷的技术可行性．研究表明，UV／H2O2联合法对二氯甲炕的降解效果较好，其最优反应条件为30％H202用量1．5mL，初始pH=3～7，吸收液循环再生流量200mL·min^-1，紫外灯功率8w．此外，考察了UV／H2O2体系氧化降解二氯甲烷的动力学特性，结果表明，在紫外光强度稳定、液相反应物均匀分布、且H2O2用量过量的条件下，该氧化降解过程遵循准一级反应动力学方程．

| Abstract: | UV, H2O2, Fenton, UV/H2O2 and UV/Fenton systems are applied to treat the simulated waste gas containing dichloromethane. The results show that： UV/Hz 02 system performs significantly, and the optimal parameters are 1.5 mL of 30% H202, 3-7 of pH, 200 mL·min^-1 of circulation fluid, and 8 W of UV. In addition, the kinetics analysis show that the oxidizing reaction of dichloromethane follows the first-order kinetic reaction, under the experimental conditions concluding stable UV light intensity, mixed reactants and the sufficient H2O2. |
