摘要
臭氧(O3)是氧的同素异性体,具有强氧化性,可直接氧化水中有机物去除污物或者由O3分子在水中产生的氧化能力更强的物质即羟基自由基,间接氧化去除有机物。臭氧氧化技术具有操作程序简单、成本价格低廉、应用广泛的特点,在工业废水实际应用深度处理方面拥有较广阔的应用前景。从臭氧性质分析出发,探讨了臭氧氧化机理,介绍了其在印染废水、造纸废水、炼油废水、医院废水等难处理废水中的应用,并重点介绍了臭氧技术与其他技术的联合工艺。
Ozone, the allotropes of oxygen, is characterized by strong oxidizing property, with direct oxidation on organic pollutants and indirect oxidation while producing hydroxyl radicals. Ozone oxidation technique has the broad cooperative prospects due to simple operation, low cost, and wide application. On the basis of ozone characteristic, ozone oxidation mechanism was discussed. In addition, the applications in the treatment for printing and dyeing wastewater, papermaking wastewater, oil refining wastewater, and hospital wastewater were introduced. Moreover, the processes of ozone technique combined with other technologies were especially introduced.
