The invention relates to a method for repairing underground water with composite pollution in a steam repair-electroplating field, which comprises the steps of extracting polluted underground water to the ground surface, and removing organic pollutants and heavy metal ions through surface sewage treatment technology; adding the agent to reinject into the groundwater, gradually reducing the pollution range and degree by continuously pumping and replacing the polluted groundwater, and removing the pollutants in the aquifer medium by converting the pollutants into water. Compared with the traditional method for repairing the composite polluted underground water, the method adopts the steps of firstly oxidizing to treat the organic pollution, simultaneously removing the organic chelating agent interfering the heavy metal precipitation, and finally adding the reductive heavy metal stabilizer into the underground water of the polluted site to achieve the aim of further repairing. The method has the characteristics of reasonable treatment process, low cost and obvious effect. |
