生物炭在土壤污染修复中的应用

Application of Biochar in Soil Pollution Remediation

摘要: 健康的土壤环境是城市发展、农业生产、宜居人居环境建设的重要基础，也是保障区域生态环境安全的重要前提。城市快速发展和经济结构转型升级过程中产生大量污染土地，对土壤、空气等人居环境和人体健康产生不可忽视的影响，污染土壤修复治理是有限土地资源高效利用的必要选择。生物炭作为一种在土壤改良、能源生产、废物利用、污染物治理等方面具有积极作用的多孔吸附性物质，在土壤污染修复领域具有重要应用价值。

Abstract: The healthy soil environment is an important foundation for urban development, agricultural pro-duction, and the construction of a livable human settlement environment, as well as an important prerequisite for ensuring the safety of the regional ecological environment. The rapid development of cities and the transformation and upgrading of the economic structure produce a large amount of contaminated land, which has a non-negligible impact on the soil, air and other human settlements and human health. Remediation of contaminated soil is a necessary choice for the efficient use of limited land resources. Biochar as a porous absorbent material with positive effects in soil improvement, energy production, waste recovery, pollutant treatment, etc., has important application value in the field of soil pollution remediation.
