活性炭在水处理中的应用方法研究与进展

Researches on the application of activated carbon to water treatment and its development

对活性炭(AC)的基本结构与性质及其在水处理中的用途进行了简要介绍,重点综述了水处理中活性炭的几种最新应用方法(包括活性炭改性以及活性炭与膜、微生物、氧化剂、微波、电、TiO2等材料或技术联用),并列出了各种方法处理的结果,表明活性炭经过一定的物化处理或与不同的材料联合应用,可以大大提高活性炭的处理效率。而且,联合应用一般比各种材料单独使用处理效果好。同时还阐述了活性炭在水处理中的研究方向,对活性炭的后续研究有参考价值。

This article introduces the essential structure and features of activated carbon(AC) and its use on water treatment. A few uptodate application of AC in water treatment, including modification of AC and its application combined with membrane,microorganism,oxidizer,microwave,electricity or TiO2 ,etc, are summarized emphatically. The results of different kinds of methods show that the efficiency of activated carbon can be promoted greatly through some physicochemical treatment or combination with different materials. Moreover, the effect of combination system is better than that of different materials applied separately. At the same time, this article also clarifies the research tendency of AC used in water treatment. All of these can be available as reference to the followup research of AC.
