摘要:
为研究Cd污染土壤固化/稳定化最优的药剂配比,以Cd污染土壤为研究对象,通过正交试验向土壤中添加波特兰水泥,磷酸二氢钙,硅藻土和高岭土4种固化剂,以固化/稳定后土壤中Cd的浸出质量浓度为评价指标,确定最优的药剂配比。实验结果表明:对Cd的固化能力较好的是波特兰水泥,可减少Cd的浸出量65.9%。对Cd最佳的药剂配比为:波特兰水泥与磷酸二氢钙的用量均为8.0‰,硅藻土的用量为6.0‰,高岭土的用量为4.0‰。
Abstract:
To study the optimal ratio of agents in solidifying/stabilizing Cd-contaminated soil, orthogonal experiments were conducted by adding curing agents, namely, Portland cement, monocalcium phosphate, diatomite, kaolin into Cd-contaminated soil, to determine an optimal agent mixing ratio by evaluating the leaching concentration of Cd in the solidified/stabilized soil. The main results of the experiments were as follows: Portland cement showed the best effect on reducing the leaching concentration of Cd by 65.9%. The best ratio of Cd were as follows: the amount of Portland cement, monocalcium phosphate, diatomite and kaolin were 8.0‰, 8.0‰, 6.0‰, 4.0‰, respectively.
