污泥活性炭制备及应用

Preparation and application of activated carbon from sludge

城市污水处理厂的污泥含有大量的有机物和有毒有害物质,如果不能妥善处理会污染环境并浪费资源。活性炭因其自身多孔材料可以去除污水中有毒有害物质,广泛应用于污水治理方向。总结了污泥活性炭的不同制备方法,探究了污泥活性炭的吸附反应模型,同时讨论了污泥活性炭在不同性质的污水处理方面的应用现状,概述了污泥活性炭在污水处理行业、大气治理行业以及土壤修复行业的应用。

Municipal sewage treatment plant sludge contains a large number of organic matter and toxic and harmful substances,if not properly treated will cause environmental pollution and waste of resources.Activated carbon is widely used in sewage treatment because of its porous material,which can remove toxic and harmful substances in sewage.This paper summarizes the different preparation methods of sludge-based activated carbon,explore the adsorption model of sludge-based activated carbon,and discusses the application status of sludge-based activated carbon in sewage treatment of different properties,summarizes the application of sludge-based activated carbon in sewage treatment industry,air treatment industry and soil remediation industry.
