光催化处理含酚废水研究进展

Progress in Treatment of Phenol-containing Wastewater by Using Photocatalysis

含酚废水主要来源于煤化工、石油化工和以苯酚或酚醛为原料的生产过程,毒性高、难降解,对所有生物个体都有毒害作用。高浓度的含酚废水可回收利用,而目前对低浓度含酚废水还没有理想的处理方法。文章阐述了半导体光催化材料光催化降解机理和光催化剂的研究进展,重点讨论了光催化材料在处理含酚废水中的应用,并对光催化材料应用的发展前景进行了展望。

Phenol-containing wastewater mainly comes from coal chemical industry,petrochemical industry and production process with phenol or phenolic as raw material.Because of high toxicity and biodegradability,it is harmful to all individual organisms.Wastewater of high phenol concentration can be recycled,whereas there seem to be incapable of dealing with its low concentration wastewater until now.Progress in research on semi-conductor photocatalysis materials and photodegradation was analyzed,and its applications of photocatalysis materials in the treatment of phenol-containing wastewater were also emphasized.The prospect of further development was presented as well.
