摘要
采用超声技术及其组合技术降解有机物废水是一种新兴的污水处理技术.对超声降解高浓度氯苯酚废水过程中的声强、pH值,溶液的初始浓度、反应温度进行了实验研究,对比单频降解与超声外加H2O2和Fe2+、加Fenton试剂强化对降解效率的影响,对比了单复频超声在不同条件下的作用效果.结果表明:降解过程中声强、pH值,溶液的初始浓度、反应温度都会对结果产生一定影响,超声与其他方法结合以及复频超声的协同作用,都会使反应进行彻底.
Degradating organic wastewater with ultrasonic technology and its combined technologies is a new sewage treatment technology. Researches the sound intensity, pH value, initial concentration of solution, reaction temperature during degradating high concentration chlorophenol wastewater with ultrasonic by experiments. Compares the degradation efficiency between single frequency and ultrasonic, H2O2, Fe^2 ＋ , Fenton reagent. Compares the effects of single and complex-frequency ultrasonic on different conditions. Results show, sound intensity, pH value, initial concentration of solution, reaction temperature can affect result on the course of degradation, combining ultrasonic and other methods,synergistic action of complex-frequency ultrasonic can make reaction exhaustivity.
