Risk management and control method for hexavalent chromium polluted land parcel by combining vertical barrier plate wall and modified microbial complexing agent
The invention discloses a risk management and control method for a hexavalent chromium polluted land parcel by combining a vertical barrier plate wall and a modified microbial complexing agent, which belongs to the field of risk management and control of a hexavalent chromium polluted site and comprises the steps of polluted land delimiting, site in-situ management and control, ex-situ remediation original foundation pit backfilling management and control and earth surface finishing horizontal management and control. The polluted land demarcation comprises the steps of paying off a land pollution red line according to a pollution range, and marking the land pollution red line. According to the method, the hexavalent chromium pollution source in the polluted site can be reduced for a long time; the viscosity of underground water in the site can be increased through microbial activity, and the fluidity of the underground water is greatly reduced; and external risk management and control can be realized through vertical blocking and horizontal blocking.
本发明公开了一种联合垂直阻隔板墙与改性微生物复合剂进行六价铬污染地块的风险管控方法，属于六价铬污染场地风险管控领域，包括污染地划定、场地原位管控、异位修复原基坑回填管控与地表整理水平管控，所述污染地划定为根据污染范围进行地块污染红线的放线，并做好标记。本发明方法可以对污染场地内部六价铬污染源进行较长时间还原；可以通过微生物活性使场地内部地下水粘度增加，大幅降低地下水的流动性；可以通过垂直阻隔和水平阻隔实现外部风险管控。
