修复渗滤液污染物的新型PRB模型构建及可行性分析

Construction of new PRB model for repairing leachate pollutant and its feasibility analysis

针对垃圾填埋场渗滤液渗漏造成土壤及地下水等环境污染及其修复技术等问题,提出由环境友好型材料雾化钢渣(PS球)和废旧轮胎橡胶构建双层生物可渗透活性反应墙系统(DBPRBs),通过可行性分析表明该系统具有生物-非生物强化协同去污能力,该新型系统的构建和研究成果将进一步揭示污染地下水的PRB修复机理,对我国地下水污染的PRB修复产业发展具有重要的理论意义和实用价值。

Aimed at the problem of leakage of leachate in landfill and repair pollution which pollutes the soil and underground water,the paper presented construction of double-layer biological permeable reactive barrier systems(DBPRBs) by environment friendly material-atomized slag(PS ball)and waste tire rubber.Analysis of feasibility shows that the system has strengthening cooperating detergency ability of biological and non biological.The achievements of the project reveal the PRB remediation mechanism of ground water pollution and advance the PRB remediation industry of ground water in our country.
