摘要
由于人类工业活动加剧,稳定存在地壳中的重金属进入土壤环境,而土壤是影响农业质量安全的源头因素,镉、镍、铜、砷、汞、铅等重金属物质会对作物造成污染,应当引起警戒。本文介绍近年来所使用的阻控技术用于土壤中重金属污染修复的研究进展,包括生物炭修复、生物修复、使用农林废弃物直接用作金属离子吸附剂以及化学钝化修复技术等,并就今后应用前景提出展望,以期为重金属污染土壤修复提供借鉴和参考。
Due to the aggravation of human industrial activities,heavy metals in the earth’s crust enter into the soil environment stably,and the soil is the source factor affecting agricultural quality and safety.Heavy metals such as cadmium,nickel,copper,arsenic,mercury and lead will pollute crops,which should be warned.This paper introduces the research progress of resistance and control technology used in the remediation of heavy metal pollution in soil in recent years,including biochar remediation,bioremediation,the use of agricultural and forestry wastes as metal ion adsorbent and chemical passivation remediation technology,and puts forward the prospect of its application in the future,in order to provide reference for the remediation of heavy metal contaminated soil.
