三种典型工业固废钝化重金属污染土壤的研究进展

Research Progress of Three Typical Industrial Solid Wastes Passivated Heavy Metal Contaminated Soils

这是一篇环境工程领域的论文。土壤重金属污染问题与我国耕地面积安全和粮食安全密切相关,将工业固体废弃物应用于钝化重金属污染土壤是一种低成本、高收益的解决方案。文章梳理了赤泥、粉煤灰和钢渣三种典型工业固废钝化重金属污染土壤的研究进展,系统总结了赤泥、粉煤灰和钢渣对土壤重金属存在状态和植物生长情况的影响作用,并对赤泥、粉煤灰和钢渣作为土壤钝化剂使用时的缺点和潜在问题进行了分析。

This is an article in the field of environmental engineering.The problem of soil heavy metalpollution is closely related to the security of arable land area and food security in China,and the applicationof industrial solid waste to passivate heavy metal contaminated soil is a low-cost and high-yieldsolution.This article combs the progress of research on the passivation of heavy metal contaminated soil bythree typical industrial solid wastes,namely,red mud,fly ash and steel slag,systematically reviews theeffects of red mud,fly ash and steel slag on the occurrence form of heavy metals in soil and crop growth,andanalyzes the disadvantages and potential problems in the use of red mud,fly ash and steel slag as soilpassivation agents.
