摘要
污水处理厂进行深度处理时,由于活性炭发达的孔隙结构和巨大的比表面积,兼具物理吸附和化学吸附双重特性,因而广泛应用于污水深度处理中。利用活性炭进行吸附,饱和后产生的废活性炭,进行热再生处理,可降低污染,提高活性炭的利用效率,实现环境和资源的双重效益。目前常见的热再生方法包括多炉膛、回转炉、过热蒸汽再生等方式,本文分析了常见的热再生处理方法的基本原理、工艺流程及特点,以及相应的评价方法,为活性炭再生利用项目提供参考与借鉴,助力活性炭再生利用在污水处理产业化应用中朝着环境友好型方向前进。
Activated carbon is widely used in wastewater treatment because of its developed pore structure and huge specific surface area,as well as its dual characteristics of physical adsorption and chemical adsorption.Using activated carbon for adsorption,the waste activated carbon produced after saturation can be thermally regenerated,which can reduce pollution,improve resource utilization efficiency,and realize the benefits of environment and resources.At present,common thermal regeneration methods include multi furnace,rotary kiln,superheated steam regeneration,etc.This paper analyzes the basic principles,process flow and characteristics of common heat regeneration treatment methods,as well as the corresponding evaluation methods,so as to provide reference and reference for activated carbon recycling projects,and help activated carbon recycling to move towards environmental friendliness in the industrial application of sewage treatment.
