复合型高锰酸钾缓释体原位修复土壤中三氯乙烯的中试实验
Pilot-Scale In-Situ Remediation of TCE in Soil by Controlled-Release Potassium Permanganate Composites
摘要
Abstract
The controlled-release potassium permanganate composites (CRPCs) mixed with paraffin and silica sand were prepared by melting and cooling method.CRPCs were used in permeable reactive barrier (PRB) and the emplace ways of CRPCs in permeable reactive barrier were compared.The experimental results show: CRPCs in horizontal placement could facilitate KMnO4 transportation more evenly than those in vertical placement.In PRB with horizontal placement of CRPCs,trichloroethylene (TCE) is degraded more effectively in horizontal influent than that in vertical influent,however TCE in effluent doesn't detected in both horizontal and vertical influent.After running 25 days,TCE removal efficiency > 99%,which indicates that CRPCs obtained by this method could be applied in the remediation of TCE contamination in soil with easy operation and low cost.关键词
