摘要
归纳了生物炭的制备原料、方法;总结了部分生物炭的全碳和灰分含量与热解温度之间的对应关系以及随着热解温度的升高,不同来源的生物炭性质大致变化规律;综述了生物炭的土壤环境效应,对土壤中不同种类污染物质的净化机理以及作为改良剂在土壤修复、低影响开发(LID)中的应用进展。最后,探讨了目前该技术存在的不足,并对该技术未来的研究重点和方向进行展望。
The raw materials and methods of biochar preparation were summarized.The relationship between the content of total carbon and ash and the pyrolysis temperature of some biochars is summarized.With the increase of pyrolysis temperature,the properties of biochar from different sources are roughly changed.The effects of biochar on soil environment,the purification mechanism of different kinds of pollutants in soil,and the application progress of biochar as an conditioners in soil remediation and low impact development(LID) were reviewed.The shortcomings of the technology are discussed,and the future research focus and direction of the technology are prospected.
