摘要
光催化技术是一种处理液相有毒有机污染物的新型技术。对有机废水的光催化降解进行了研究,综合论述了影响光催化效率的各种因素,如晶粒尺寸、pH值、光照强度、外加氧化剂等。同时,对提高光催化效率的途径以及光催化反应器的设计因素进行了讨论。
Photo-catalysis is an emerging technology to provide new routes for destruction of liquid phase toxic chemicals. The degradation of organic wastewater by photo-catalysis and the effects of various parameters such as particle size, pH value, light intensity, exterior oxidants were analyzed. The approaches for improving photo-catalytic efficiency and the design features of photo-reactors were discussed.
