The regeneration methods of activated carbon are classified,among which the microbial regeneration,oxidation regeneration in chemical methods and decomposition regeneration in physical methods,are introduced emphatically.Because the above three methods have good universality for efficient removal of various organic pollutants,they are suitable for regeneration of saturated coal-based granular activated carbon (CGAC).The advantages and disadvantages of relevant regeneration methods,as well as their improvements and development directions are also reviewed.According to the present condition of water treatment industry (the kinds of organic pollutants in water are various and the ozone-biological activated carbon (O3-BAC) technology is widely used),the author points out that in future research on the CGAC's regeneration,innovation should be carried out by concerning the advantages of different regeneration methods,and the research work about saturated BAC regeneration should be emphasized.Moreover,the regeneration method should be systematically studied and evaluated by comparing the technical and economic parameters of thermal regeneration method which is widely used in the industry at present.%对活性炭的再生方法进行了分类,着重介绍了微生物再生、化学再生法中的氧化再生和物理再生法中的分解再生,这3类方法可有效去除各类有机污染物,因此通用性较好,较适用于水处理中煤基颗粒活性炭(CGAC)的再生.对相关再生方法的优缺点及其改进、发展的方向进行了综述.针对目前水中污染物种类的多样化以及臭氧生物活性炭技术(O3-BAC)的大规模使用,指出在未来进行CGAC的再生研究时,应结合不同再生方法的优点进行创新,同时进一步加强饱和BAC再生的研究工作;并以目前工业上普遍使用的热再生方法的技术与经济参数为参照,对再生过程进行系统的研究与评价.
