O_3/H_2O_2高级氧化技术在处理难降解有机废水中的应用进展

Application of advanced oxidation process with O_3/H_2O_2 for refractory organic wastewater treatment

O3/H2O2高级氧化技术具有氧化能力强和无选择性等优点,被广泛用于高浓度、难降解和有毒有害的有机废水处理,并取得了显著的效果。本文介绍了O3/H2O2高级氧化技术的氧化反应机理,综述了O3/H2O2高级氧化法在饮用水、印染废水、造纸废水、农药废水、焦化废水、炸药废水、垃圾渗滤液处理中的应用研究进展,指出了处理不同的废水体系,O3与H2O2的合适比例是至关重要的。

Advanced oxidation process（AOP）with O3/H2O2 exhibits advantages of strong oxidation capacity and non-selectivity and has been widely used in the treatment of high-concentration,refractory,toxic and harmful organic wastewater. This review presents the mechanisms of O3/H2O2 AOP,and summarizes the application advances of O3/H2O2 AOP in the treatment of drinking water,printing and dyeing wastewater,papermaking wastewater,pesticide wastewater,coking wastewater,explosive wastewater and landfill leachate. It is indicated that the control of suitable O3 to H2O2 ratio for different wastewater systems is crucial for the degradation of organics.
