在底泥处理处置工程中，对于重度污染底泥，目前使用的固化剂处理后余土往往还达不到资源化利用的要求。本研究通过大量试验，并在检测分析基础上得出了固化剂改进配方，使铜的浸出值从1.87 mg/L下降到<0.01 mg/L，使固化处理后余土达到了资源化利用的标准要求，提高了固化余土的资源化利用率，取得了良好的经济社会与环境效益。
For the heavily polluted sediment in the sediment treatment and disposal project, the residual soil after the treatment of curing agent often cannot meet the requirements of resource utilization. The purpose of the project is to improve the formula of curing agent and improve the utilization rate of resources. In this study, a large number of tests were conducted and improved formula of curing agent was obtained based on detection and analysis. Leaching value of heavy metal Cu from 1.87 mg/l to <0.01 mg/l. The improved curing agent was applied in production, which made the residual soil meet the standard requirements of resource utilization and achieved an ideal practical effect.
