生物炭的制备及其环境应用的研究进展

Progress in the preparation of biochar and its environmental application

综述了生物炭的制备以及工艺参数对其理化性质的影响,并对生物炭改良环境的机理以及目前在土壤修复中的应用进行了分析。中国农业仍处于初级,农业的应用渗透率还不足1%。但得益于社会环境的发展以及农业科技水平的不断提升,中国的农业行业正在不断前进。国内外农业的主流模式仍依赖石油化学技术,但这种模式正在向现代农业逐渐递进,未来农业的方向更倾向于生物农业和生态农业。基于对生物炭研究进展的综述,对其未来发展提出制定统一的生物炭性质基本标准、对生物炭进行分门别类的研究、结合环境实际应用进行考量、深度研究生物炭对环境长久的影响、考虑生物炭在经济价值层面发展等建议。

The preparation of biochar and the effects of technological parameters on its physicochemical properties were reviewed.The mechanism of biochar improving the environment and its application in soil remediation were analyzed.Chinese agriculture is still in the primary stage,and the application penetration rate of agriculture is less than 1%.However,due to the development of social environment and the continuous improvement of agricultural science and technology,Chinese agricultural industry is moving forward.The mainstream mode of domestic and foreign agriculture still depends on petrochemical technology,but this mode is gradually progressing to modern agriculture,and the future direction of agriculture is more inclined to biological agriculture and ecological agriculture.Based on the review of the research progress of biochar for its future development,some suggestions were put forward,such as establishing a unified basic standard for the nature of biochar,conducting separate studies on biochar,considering the practical application of the environment,conducting in-depth research on the long-term impact of biochar on the environment,and considering the development of biochar in terms of its economic value.
