摘要
我国每年都会产生大量农林废弃物,焚烧处理会造成严重的大气污染,将农林废弃物转化为生物炭是实现资源回收利用的方法之一.农林废弃物生物炭是农林废弃物经高温热解炭化而形成的富碳型产物.因其原材料来源广泛、比表面积大、孔隙结构丰富、表面官能团易调控等优势,在土壤改良和环境修复方面有着良好的应用前景.本文对农林废弃物生物炭的制备方法和应用进展展开论述,并针对农林废弃物生物炭在农业推广中的发展方向进行展望.
Abstract
A large number of agricultural and forestry wastes are produced in China every year,and incineration will cause serious air pollution.Converting agricultural and forestry wastes into biochar is one of the ways to realize resource recycling.Biochar from agricultural and forestry wastes is a carbon-rich product formed by pyrolysis and carbonization of agricultural and forestry wastes at high temperature.Because of its advantages such as wide source of raw materials,large specific surface area,rich pore structure and easy regulation of surface functional groups,it has a good application prospect in soil improvement and environmental remediation.In this paper,the preparation methods and application progress of biochar from agricultural and forestry waste are discussed,and the development direction of biochar from gricultural and forestry waste is prospected.
