Situation and Progress in Treatment Process of Phenolic Wastewater

Phenols are organic pollutants of high priority concerns because of their toxicity and possible accumulation in the environment. It is important to treat and recover phenols from wastewater economically and effectively. In this paper,the source and harm of phenolic wastewater were introduced. The situation and progress in treatment process of phenolic wastewater,including absorption,extraction,oxidation process,and biological treatment are also summarized. The characteristics,main problems ,area and further application of each treatment process are pointed out. The developing trend on combination treatment of phenolic wastewater is further described.
