Embodiment Construction
[0020] See Figure 1~2 As shown, the device for repairing hexavalent chromium-contaminated groundwater by the upflow PRB technology of the present invention includes a pumping system, a water distribution system and a packing system. The pumping system is set at the downstream of the water flow, the water distribution system is set at the upstream of the water flow, and the filling system is set at the upper surface of the soil upstream of the water flow. The facilities are simple, easy to construct and manage, and have strong operability, which is convenient for the later stage. Material replacement and management greatly reduces the cost of restoration.
