Embodiment 1
[0034] A composite media PRB restoration method for organically polluted groundwater, comprising the steps of:
[0035] (1) Investigate the geological structure, geotechnical properties, aquifer thickness, low water table, groundwater depth, groundwater velocity, groundwater flow rate, concentration of pollutants and spatial distribution of pollutants in the area to be treated.
[0036] (2) Calculate the size of the groundwater pollution plume, and delineate the pollution area according to the size of the pollution plume.
[0037] (3) Four parallel trenches are excavated downstream of the groundwater pollution plume and perpendicular to the direction of groundwater flow. The four trenches are divided into gravel layer, first reaction layer, second reaction layer and adsorption layer in sequence along the direction of groundwater flow. , and are filled with gravel filler, parts iron reaction filler, biological reaction filler and activated carbon filler respectively.
