摘要
介绍了表面覆盖和封装、土壤置换、热固定和玻璃化、固化/稳定化、热解吸法、化学冲洗法、电动法、植物法等常用重金属污染修复技术,分析了各项技术的绿色可持续性,并对生物炭法和植物法2种绿色修复技术的研究方向提出建议。
Common remediation technologies for heavy metal pollution are introduced,including surface covering and packaging,soil replacement,thermal fixation and vitrification,microbial method,solidification/stabilization,thermal desorption method,chemical flushing method,electric driving method and phytoremediation.The green sustainability of various technologies is analyzed.Suggestions on the research direction of biochar remediation and phytoremediation,two green remediation technologies,are put forward in order to provide reference for performing green and efficient remediation to heavy metal contaminated soil.
