The invention discloses a method for repairing groundwater pollution, which belongs to the field of groundwater pollution, and comprises the steps of excavating a guide wall along a cross section on a runoff channel of groundwater pollution; laying repair layers in layers in the guide wall; and laying the repair layers sequentially along the direction of groundwater flow. It includes an ore layer, a drug layer, an active carbon layer and a microorganism layer; the microorganism layer is provided with a gas inlet. A gas inlet is provided in the microbial layer. The layer of microorganisms includes Assillaria, Bacillus subtilis and humus. The invention firstly filters through the mineral layer, then adjusts through the chemical layer, decomposes and adsorbs the soil and groundwater through the microbial layer, and then decomposes and adsorbs and purifies the activated carbon layer, which can absorb heavy metal ions, degrade organic matter in water, and remove groundwater organic pollutants, improve the treatment capacity of underground sewage. |
