含酚废水处理技术研究进展

Research Progress of Treatment Technology of Phenolic Wastewater

石油化工、炼油、焦化等行业不断发展,除了带来经济上的发展,还产生大量的含酚废水,对水体构成严重污染,很难被降解。含酚废水中的主要物质苯酚及其衍生物是一种原生质毒物,不仅对饮用水水源有危害作用,其毒性还会对水生生物产生不利的影响,因此含酚废水的治理不容忽视。国内外学者针对这个问题分别在物理、化学及生物方面进行了研究,提出了吸附、气提、电化学氧化法、还原、生物膜、固定化微生物技术等方法,不断完善含酚废水的处理途径。

The petrochemical,refining,coking and other industries continue to develop. In addition to bringing economic development,a large amount of phenol-containing wastewater is produced, which poses serious pollution to water bodies and is difficult to be degraded. Phenol and its derivatives, the main substance in phenol-containing wastewater, are a protoplasmic poison, which not only has harmful effect on drinking water sources, but also has adverse effect on aquatic organisms. Therefore, the treatment of phenol-containing wastewater cannot be ignored. Domestic and foreign scholars have studied the physical, chemical and biological methods to solve this problem, and adsorption, stripping, electrochemical oxidation, reduction, biofilm, and immobilized microbial technologies were developed to continuously improve the treatment of phenol-containing wastewater.
