Polluted soil and underground water integrating circulating well repair system

The utility model provides a polluted soil and underground water integrating circulating well repair system, comprising a water pumping well in a polluted soil area, wherein the water pumping well is sequentially divided into a lower segment, a middle segment and an upper segment from bottom to top; a first well sieve is arranged on the lower segment; the lower segment and the middle segment are partitioned by a separation plate; a microbial culture packing and/or a repair agent are put into the middle segment; a water outlet is formed in the side wall of the middle segment; a reservoir is arranged on the upper segment; a water-permeable structure is arranged at the bottom of the reservoir; a pumping pump is arranged in the lower segment, and is communicated with the reservoir through a water pipe; the reservoir is connected with a pipe network system; a spray opening is formed in the pipe network system; an active reaction layer is arranged at the lower part of the pipe network system; and the microbial culture packing or the repair agent is filled into the active reaction layer. According to the polluted soil and underground water integrating circulating well repair system, the construction difficulty in engineering is simplified; the mixing degree of the repair agent and the soil and underground water is increased; the hydraulic retention time is prolonged; the chemical action and the activity of microorganisms can be significantly improved; and the repair effect is enhanced.
