摘要:
将重金属污染土样于300~700 ℃下焙烧处理0~8 h,分析土样中有效态锌、铜浓度变化,以优化焙烧热处理技术固定土壤中锌、铜的条件。结果表明,500 ℃焙烧0.5 h可以达到土样中锌、铜的最佳固定效果;该条件下,土样中有效态锌、铜浓度可以从处理前的995.73、769.92 mg/kg分别下降到处理后的36.56、61.10 mg/kg,锌、铜固定率分别高达96.33%、92.06%,处理后土样中锌、铜浓度均低于我国展览会土壤环境质量相关评价标准中的A级标准限值。焙烧热处理可有效固定土壤中锌、铜,该技术工艺简单、快速、效果好,无须向土壤添加任何固定剂,无二次污染问题,有望被用于高潜在附加值重金属污染场地土壤的治理。
