摘要
目前,我国土壤重金属污染依然比较严重,必须进一步强化重金属污染物排放控制,有效防控涉重金属环境风险。本文结合具体案例,采用固化/稳定化技术对锌污染土壤进行修复试验,然后开展修复效果评价。经实践验证,土壤中锌浸出量远低于《地下水质量标准》(GB/T 14848—2017)的Ⅲ类标准限值,达到修复效果。
At present,soil heavy metal pollution in China is still relatively serious,and it is necessary to further strengthen the control of heavy metal pollutant emissions and effectively prevent and control environmental risks related to heavy metals.Based on specific cases,this paper adopts solidification/stabilization technology to conduct remediation experiments on zinc contaminated soil,and then evaluates the remediation effect.Through practical verification,the amount of zinc leaching in soil is far below the ClassⅢstandard limit specified in the“Groundwater Quality Standard”(GB/T 14848—2017),thus achieving remediation effects.
