磷酸钾镁胶结材料固化/稳定化重金属污染土壤的研究
Solidification/Stabilization of Heavy Metal Contaminated Soil with Magnesium Potassium Phosphate Cements
摘要
Abstract
[Objective] The research aimed to ensure food safety and human health,improve soil quality. [Method] Magnesium potassium phosphate cements material was adopted to solidified/stabilized soil contaminated by Pb,Cr,Cd,Zn,et al. [Result]Solidified strength mixed with 10% -40% magnesium potassium phosphate cements were more than 1 Mpa,which showed that solidified had a high compressive strength and met the requirements of storage and landfill. Leaching concentrations of Pb,Cr,Cd weren' t detected after solidified mixed with 40% magnesium potassium phosphate cements was conserved 28 d and leaching concentrations of solidified mixed with 10% magnesium potassium phosphate cements far less than standard limit values. Different metals had different leaching law and cumulative leaching of metal in descending order was Zn > Cd > Cr > Pb. [Conclusion] Magnesium potassium phosphate cements material was a better heavy metal contaminated soil stabilizer.关键词
