| 摘 要： | 采用超声辐照技术去除垃圾渗沥液中的有机污染物。研究了输入电功率、初始浓度、初始pH、曝气对垃圾渗沥液中COD的超声去除效果影响,探讨了垃圾渗沥液中有机物的超声去除主要是通过羟自由基的氧化反应,高温热解反应虽然存在,但贡献相对很小。超声去除垃圾渗沥液中COD的动力学模式不能简单用动力学原理来解释,一方面由于超声降解有机物的机理和垃圾渗沥液中有机物的种类都很复杂,另一方面由于基于K2Cr2O7法测定出的COD指标不能完全表征超声去除垃圾渗沥液中有机污染物的程度。

| Abstract: | Ultrasound irradiation was used to remove organic pollutants from landfill leachate. The effect of ultrasonic removal of COD from landfill leachate by power input, initial concentration, initial pH and air aeration was studied systematically. Main sonolysis of landfill leachate proceeded via reaction with .OH radicals, a thermal reaction also occurred although its contribution was small. The kinetics of COD removal from landfill leachate could be described by complexity of organic pollutant sonolysis and organic pollutants in landfill leachate and COD measurement based on K2Cr2O7 method. |
