    摘要:

    生物质炭由于其特殊的多孔性结构、强的吸附性能,以及富含多种营养元素和特殊官能团等特点,成为近年来在农业应用和环境污染治理方面的热点。本文介绍了生物质炭的基本特性,提出生物质炭可能在今后成为活性炭的替代品;综述了生物质炭在修复有机物(石油烃、有机农药、PAHs、PCBs)污染土壤中的研究进展,并探讨了生物质炭应用于污染土壤修复的环境风险。生物质炭在修复有机物污染土壤方面有巨大的潜力,但在大规模应用之前还需要做长期深入的研究。

    Abstract:

    Biochar, with the characteristics of porosity structure, high capability of adsorption, and containing much nutrient elements and functional groups, is a new functional material which has been paid more and more attentions in the fields of environment and agricultural application. In the present article, the basic properties of biochar were briefly introduced, and the probability that biochar became a substitute for activated carbon in the future was proposed. The applications of biochar to remediate contaminated soil with organic contaminant such as TPHs, pesticide, PAHs, PCBs, and also the environmental risk of using biochar as soil addition were reviewed in the paper. The conclusion indicated that biochar has a great potential to remediate contaminated soils, but both its effect and environment impact deserve more studies.
