| 中文摘要: |
| 重金属原位钝化是一种农田土壤污染修复技术，钝化材料能有效降低重金属迁移性及生物有效性。本文综述了用于原位钝化修复的钝化材料及其钝化机理，探讨了钝化材料对重金属污染农田钝化效果的影响因素。并对钝化产品的市场研发及农田修复后需要解决的问题进行了分析和展望，以期为原位钝化修复技术和钝化材料的研发提供理论基础和研究方向。 |
| 英文摘要: |
| In-situ passivation of heavy metals is a technology for remediation of farmland soil pollution. It adds passivation material to the contaminated soil, to reduce effective concentration of heavy metals in the soil or change its redox state. This paper summarized the passivation materials and its passivation mechanism for in-situ passivation repaired technology, and discussed the influencing factor for passivated effect of passivation materials on heavy metal contaminated farmland. In addition, This paper analyzed and forecasted the problems for market development of passivation materials and repairing farmland that need to be solved in the futureare, so as to provide theoretical basis and research direction for in-situ passivation repaired technology and passivation materials. |
