| 摘 要： | 过硫酸盐作为良好的氧化剂被广泛应用于有机污染土壤的修复领域,但残留的过硫酸盐和氧化反应产生的副产物对建筑物的混凝土和钢结构产生的腐蚀性影响往往被忽视。通过对某多环芳烃类土壤污染地块修复前后的土壤相关指标的分析检测,分析了该地块污染土壤采用过硫酸钠体系修复后对建筑材料的腐蚀性产生的影响。实验结果表明,修复后土壤对混凝土和钢结构的腐蚀性有所加重。

| Abstract: | Persulfate is widely used in the remediation of organic contaminated soil as a good oxidant, but the corrosive effects of residual persulfate and by-products from oxidation reaction on building concrete and steel structures are often ignored. Through the analysis and detection of soil related indexes before and after remediation of a polycyclic aromatic hydrocarbon soil contaminated plot, the influence of the contaminated soil on the corrosivity of building materials after remediation with sodium persulfate system has been analyzed. It is showed that the corrosion of the repaired soil to concrete and steel structures has increased. |
