摘 要: 以城市生活垃圾渗滤液作为研究对象 ,采用悬浮态半导体催化剂对渗滤液进行处理试验。研究了ZnO TiO2复合半导体催化剂的催化活性 ,并研究了各种实验条件、影响因素及处理效果。研究表明 ,在一定的试验条件下 ,用ZnO TiO2 复合半导体催化剂处理城市垃圾渗滤液效果较好 ,可作为垃圾渗滤液的深度处理。同时得到光催化氧化法处理渗滤液的最佳试验参数。 In this paper, the main object is the landfill leachate which is treated by suspending semiconductor catalysis. The photo-catalysis activity of ZnO/TiO 2 composition semiconductor, the experimental conditions and the influencing factors are also discussed. In the end of this paper, the best experimental conditions are presented and the research shows that under selected conditions, using ZnO/TiO 2 composition semiconductor to treat the landfill leachate has good efficiency.
