摘要
重金属在污染场地土壤中的分布具有不均匀性和多样性,降低了土壤重金属分布特征的获取精度。为优化土壤修复效果,提出污染场地土壤重金属分布特征及修复技术研究。该技术首先确定研究目标区域概况,基于分析结果确定采样点位置布设采样点;根据采样样本检测重金属元素浓度含量,提取土壤重金属分布特征;最后根据提取的特征,选取微波强化[S,S]-乙二胺二虎珀酸淋洗方法作为土壤重金属污染修复方法,完成土壤重金属污染修复。研究结果表明,使用该技术完成土壤在重金属污染修复时,能够将污染场地重金属污染浓度有效降低,修复效果好。
The distribution of heavy metals in contaminated soil is uneven and diverse,which reduces the accuracy of obtaining soil heavy metal distribution characteristics.To optimize the effectiveness of soil remediation,research on the distribution characteristics of heavy metals in contaminated soil and remediation techniques is proposed.This technology first determines the overview of the research target area.Based on the analysis results,the location of sampling points and arranges sampling points are determined.The paper detects the concentration of heavy metal elements based on sampled samples and extract the distribution characteristics of soil heavy metals.According to the extraction characteristics,the microwave enhanced[S,S]-Ethylenediamine dihuopoxylic acid leaching method was selected as the remediation method of soil heavy metal pollution to complete the remediation of soil heavy metal pollution.The research results indicate that using this technology to complete the remediation of heavy metal pollution in soil can effectively reduce the concentration of heavy metal pollution in the contaminated site,and the remediation effect is good.
