| 摘 要： | 研究了在超声／H2O2联合作用下，超声场中甲醛的降解过程，考察了超声时间、甲醛浓度、pH值、氧化剂H2O2的浓度等因素对降解率的影响．实验结果表明：甲醛的初始浓度与降解率基本成线性关系；pH值的变化对降解率影响较大，超声波／H2O2联合工艺与单独超声作用相比，降解率有了显著的提高，通常处理100min后，可以获得85％的降解率，其降解过程符合一级动力学方程．

| Abstract: | Treatment of wastewater containing is experimentally studied by ultrasound/H_2O_2. The influence of several different parameters is investigated including the initial pH value of waster water, reaction time, the concentration of H_2O_2, sound intensity. The result shows that the removal efficiency of formaldehyde will be continuously improved by increasing reacting time. Usually treatment after 100 minutes can acquire the 85.53% degradation .The degradation of formaldehyde by ultrasound/H_2O_2 follows a pseudo-first order reaction. |
