摘要
随着我国水处理厂普及率逐渐上升,剩余污泥产量增长迅速,且因其危害性高、难处理的特点,在环境污染治理中备受关注。污泥基生物炭是以污泥为原料通过热解方式制得的固体产物,因其良好的吸附和催化性能被广泛应用于环境介质中各类污染物的去除。本文对污泥基生物炭的制备方法、热解温度对其理化性能的影响及其改性处理的研究进展进行了综述,并对其催化机理研究、回收再利用和应用于土壤污染治理的前景作出了展望。
With the increasing popularity of water treatment plants in China,the output of excess sludge has increased rapidly,and it has attracted much attention in environmental pollution control because of its high harmfulness and difficult treatment.sludge-based biochar is a solid product made from sludge by pyrolysis.It has been widely used to remove various pollutants in environmental media because of its good adsorption and catalytic performance.In this paper,the research progresses on sludge-based biochar about the preparation methods,the influence of pyrolysis temperature on its physical and chemical properties and the modification treatment are reviewed,and the prospect of research on the catalytic mechanism,recycling,and application in soil pollution control of sludge biochar is put forward.
