本研究以超声波／Ｈ２Ｏ２工艺对水中含氯有机物邻氯酚（２－ｃｈｌｏｒｏｐｈｅｎｏｌ）的氧化分解进行探讨，反应控制的参数包括超声波振幅、过氧化氢的添加量、ｐＨ值、离子强度以及有机物的初始浓度等。根据试验结果，提高超声波的振幅可提高有机物的去除率；改变溶液的ｐＨ值使其低于邻氯酚的酸碱离解常数时，邻氯酚较易被氧化分解；提高溶液的离子强度时，对有机物的氧化分解亦具正面效果；有机物的初始浓度越低，邻氯酚的分解速率越快；过氧化氢的添加，可使溶液中的氢氧自由基的浓度增加，邻氯酚的氧化分解率较单独使用超声波工艺时高出许多。本研究的最佳操作条件为：超声波振幅１２０μｍ、ｐＨ值控制于３、离子强度控制于０１Ｍ、过氧化氢的添加量为２００ｍｇ／Ｌ，于邻氯酚的初始浓度为１００ｍｇ／Ｌ，反应３６０ｍｉｎ后，邻氯酚的分解率可达９９％，总有机碳的去除率则为６３％。
In this study, the oxidative decomposition of 2-chlorophenol, which is a chlorine-containing organic substance in water, was investigated by ultrasonic / H2O2 process. The parameters of reaction control included the amplitude of ultrasonic wave, the amount of hydrogen peroxide, pH value, ionic strength and the initial Concentration and so on. According to the experimental results, increasing the amplitude of the ultrasonic wave can improve the removal rate of organic matter; when the pH of the solution is changed to be lower than the acid-base dissociation constant of the ortho-chlorophenol, the o-chlorophenol is more easily oxidized and decomposed; when increasing the ionic strength of the solution, Oxidative decomposition of organic matter also has a positive effect; the lower the initial concentration of organic matter, o-chlorophenol decomposition rate faster; hydrogen peroxide, the solution can increase the concentration of hydroxyl radicals, o-chlorophenol oxidation Decomposition rate higher than when using ultrasonic technology alone. The optimum operating conditions of this study were as follows: ultrasonic amplitude 120μm, pH value 3, ionic strength 0.1M, hydrogen peroxide 200mg / L, initial concentration of o-chlorophenol 100mg / L, After 360min reaction, the decomposition rate of o-chlorophenol was 99% and the total organic carbon removal rate was 63%.
