浅谈生物炭在农业土壤重金属污染修复中的应用

Application of Biochar in Remediation of Heavy Metal Pollution in Agricultural Soil

本文系统介绍了生物炭在农业土壤重金属污染修复中的应用及存在的问题,并提出了相应的对策建议。首先,本文介绍了生物炭在重金属污染修复中的优势和应用方式;然后从涂层过厚、碱化、微生物群落改变、潜在环境风险等方面阐述了生物炭应用中存在的问题;最后从控制涂层厚度、探索新型涂层材料、指定处理方法、做好环境风险评估等角度提出了对策建议。本文旨在为生物炭在农业土壤重金属污染修复中的应用提供参考,并为相关研究提供一定的借鉴和启示。

This article systematically introduces the application and existing problems of biochar in the remediation of heavy metal pollution in agricultural soil,and proposes corresponding countermeasures and suggestions.Firstly,the advantages and application methods of biochar in heavy metal pollution remediation were introduced.Then,the problems in the application of biochar were elaborated from aspects such as excessive coating thickness,alkalization,changes in microbial communities,and potential environmental risks.Finally,countermeasures and suggestions were proposed from the perspectives of controlling coating thickness,exploring new coating materials,specifying treatment methods,and conducting environmental risk assessments.This article aims to provide reference for the application of biochar in the remediation of heavy metal pollution in agricultural soil,and provide some reference and inspiration for related research.
