臭氧氧化技术在水处理中的应用研究

Application of Ozone in Water Treatment

臭氧是一种强氧化剂,具有很强的氧化性,广泛地应用于水处理。臭氧可以氧化多种化合物,具有反应速度快,耗能小,不产生污泥等特点。鉴于臭氧的种种优点,因而在饮用水、产业废水及循环冷却水处理中起到重要作用。随着工业技术的革新,人们发现臭氧消毒的效率要远优于氯消毒,不会在消毒过程中产生对人体有害的三氯甲烷(THMS),并且还可以有效去除水中的色、臭、味、和铁、锰等无机物质,并能降低UV吸收值、TOC、COD及氨氮。因此,臭氧氧化技术被越来越广泛地应用于产业废水处理中,并发展许多复合处理工艺。

Ozone is a strong oxidant,has a strong oxide,widely used in water treatment.Ozone can oxidize a variety of compounds,with fast response,low energy consumption,does not produce sludge and so on.Given all the advantages of ozone,which in drinking water,industrial wastewater and cooling water play an important role.As industrial technology innovation,the efficiency of ozone disinfection was found to be much better than chlorine disinfection,sterilization process does not produce harmful chloroform（THMS）,and can also effectively remove color,smell,taste,and iron,manganese and other inorganic substances,and can reduce the UV absorption value,TOC,COD and ammonia nitrogen.Therefore,the ozone oxidation technology is more widely used in water treatment,and many of Multiple Process Development.Based on the understanding of ozone oxidation of the technology described in the drinking water treatment,industrial wastewater treatment and other fields.
