摘要
由于当前工农业的快速发展,我国大部分地下水资源已经遭到了各种程度的污染。而生物炭及其改性材料良好的理化特性,使其在保护环境领域中发挥了日益巨大的功能。但鉴于地下水环境复杂性,对生物炭及其改性材料在面向地下水处理的问题上深入研究相对较少,且目前还只停留在实验室阶段,在实际使用中依然存在着吸收效能低下、对目标污染物选择性能力减弱、处理较难等一系列问题。本文总结了生物炭材料的制备方法、改性方法、对有机污染物的吸附机理以及目前在水环境领域中的研究和应用,指出未来以污泥作为生物炭制备的原材料有着巨大的潜力。最后通过对目前地下水处理技术的分析,总结了生物炭及其改性材料在地下水环境中应用的现状,探讨了生物炭及其改性材料未来在地下水实际应用的前景和不足。
Due to the current rapid development of industry and agriculture,most of the groundwater resources have been polluted to various degrees.The good physical and chemical properties of biochar and its modified materials make it play an increasingly great function in the field of environmental protection.However,in view of the complexity of the groundwater environment,in-depth research on biochar and its modified materials for groundwater treatment is relatively little,and currently remains only in the laboratory stage.There are many problems,such as low absorption efficiency,weakened selectivity of the target pollutants,and difficulty in practical use.This paper reviews the preparation method,modification method,adsorption mechanism of organic pollutants,and the current research and application in the field of water environment,and points out that there is a great potential for sludge as the raw material for biochar preparation in the future.Finally,through the analysis of the current groundwater treatment technology,we summarize the current status of the application of biochar and its modified materials in the groundwater environment,and discuss the prospects and shortcomings of the future practical application of biochar and its modified materials in groundwater.
