摘要
作为现今净水厂深度处理的主流技术,臭氧-生物活性炭工艺通过将臭氧氧化、活性炭吸附降解联用,具有绿色、高效、处理效果好等优点。本文对O_(3)-BAC工艺的关键影响因素--臭氧氧化副产物及活性炭理化性质进行了探讨,综述了臭氧氧化有机污染物的过程,副产物对活性炭吸附以及生物降解的影响,深入分析了活性炭孔隙结构、官能团、π电子供受体及表面电荷等理化性质对其吸附以及生物降解过程的影响,对O_(3)-BAC工艺设计提出了合理建议。
As the mainstream technology for depth processing of water treatment plant nowadays,the O_(3)-biological activated carbon process combines ozone oxidation and activated carbon adsorption and degradation,which has advantages such as green,efficient,and good treatment effect.This article discussed the key influencing factors of O_(3)-BAC process,including ozone oxidation by-products and physicochemical properties of activated carbon,reviewed process of ozone oxidation of organic pollutants,the impact of oxidation by-products on the adsorption and biodegradation of activated carbon,and the effects of physical and chemical properties such as pore structure,functional groups,πelectron donors and acceptor,and surface charges on the adsorption and biodegradation process of activated carbon,provided reasonable suggestions for the design of the O_(3)-BAC process.
