| 摘 要： | 用双氧水联合空化水射流氧化法,以苯酚模拟废水为研究对象,考察多种因素对苯酚去除率的影响,并通过高效液相色谱分析反应中间产物,揭示其降解机理.实验结果表明,当苯酚初始质量浓度为100 mg/L,溶液pH值为3.0,双氧水质量浓度为300 mg/L,泵压及围压分别是20、0.5 MPa时,苯酚的去除率达到了99.85%.高效液相色谱分析表明,苯酚降解的中间产物主要是对苯二酚、邻苯二酚、苯醌及其他有机小分子物质,最终产物为顺丁烯二酸、乙酸.

| Abstract: | We studied experiments on phenol wastewater treated by hydrogen peroxide assisted with a cavitating water jet.Removal efficiency factors were studied,and the intermediate products analyzed by High performance liquid chromatography(HPLC) to reveal the degradation mechanism.The optimal cavitating condition was obtained via experimentation.Based on the results,the removal ratio of phenol reaches 99.85% under when the initial phenol concentration is 100 mg/L,the pH value is 3.0,the hydrogen peroxide concentrati... |
