摘　　要：为评估腐殖酸盐改良技术在修复重金属污染土壤中的效果及其机理,通过对上海市某处铅污染农田土壤进行实验,使用腐殖酸作为吸附剂,设计了8个试验组,包括7个处理组和1个对照组,以探讨不同处理浓度和条件下对土壤中铅含量及土壤性质的影响。实验结果显示,腐殖酸改良剂对土壤pH值的影响有限,但对电导率和铅含量有显著影响。粉煤灰(FM)和腐殖酸组合(H1、H2)处理在减少铅污染土壤中铅的淋溶方面表现出较好的效果。未来的研究应进一步探索腐殖酸盐对不同类型和浓度重金属污染土壤的修复效果,以及其在不同环境条件下的稳定性和生态影响。To evaluate the effectiveness and mechanism of humic acid salt improvement technology in the remediation of heavy metal contaminated soil,an experiment was conducted on lead-contaminated farmland soil in Shanghai.Humic acid was used as an adsorbent,and 8 experimental groups were designed,including 7 treatment groups and 1 control group,to explore the effects of different treatment concentrations and conditions on lead content and soil properties.The results showed that humic acid amendment had limited effect on soil pH,but had a significant effect on conductivity and lead content.The combination of fly ash(FM)and humic acid(H1 and H2)treatments showed good results in reducing the leaching of lead in lead-contaminated soil.Future studies should further explore the remediation effects of humate on different types and concentrations of heavy metal contaminated soils,as well as its stability and ecological impacts under different environmental conditions.
