活性氧-臭氧联用处理含酚废水

用羟基自由基活性氧与臭氧联合使用处理含酚废水，并在电磁波作用下对含酸废水进行了研究，考察了活性氧药剂投加量和反应时间对苯酚去除率和COD去除率的影响，并对这些方法的处理效果进行了比较分析。结果表明，活性氧药剂与臭氧联用，并辅以微波能场的方法处理含酸废水表现出了明显的优势，具有最好的处理效果。对于浓度为0.500g/L的含酚废水，在处理时间为5min的条件下，苯酚去除率达到98.23%，COD去除率达到68.12%。

Combined use of hydroxyls radicals and ozone to treat phenolic wastewater

Processes involving hydroxyl radical oxidization and ozone oxidization have been applied separately for wastewater treatment,and so their combination may be an effective approach for oxidative decomposition of aqueous phenol.The effect of adding hydroxyl radicals on chemical oxygen demand(COD) and phenol removal has been studied using simulated wastewater.The effect of varying the reaction time was also investigated.The results indicated that a combination of both processes was most effective and for phenol wastewater with concentration of 0.500 g/L,phenol removal of 98.23% and COD removal of 68.12% were attained.
