臭氧氧化技术在环境科学中的应用

摘要

综述了臭氧氧化的作用机理和臭氧氧化技术在空气净化,固体处理中及水处理方面的研究及应用现状,并介绍了包括生物活性炭法（BAC）、臭氧-双氧水联用法（O3/H2O2）、光催化臭氧化法（O3/UV）等几种较先进的复合臭氧化处理工艺,指出臭氧与传统的氧化剂相比不仅可以避免产生有机氯化物,而且还具有能提高过滤速度,减少滤池数量,促进絮凝,减少絮凝池数量和絮凝剂用量,延长滤池使用时间,减少冲洗水耗量,提高水质水感等优点。%The mechanism,research progress and application of ozone oxidation technologies in air purification,solid disposal and wastewater treatment are reviewed.The combination of ozone oxidation and other technologies including BAC,O3/H2O2,O3/UV are introduced.Compared with traditional oxidants,ozone oxidation not only avoid chlorinated organic compounds,but also improve the speed of filtration,reduce number of filter tanks,promote flocculation and reduce number of flocculation tanks and flocculants dosage,extend the filter tank usage time,reduce rinse water consumption and improve the water quality.
