The utility model relates to the technical field of groundwater remediation treatment, and provides an efficient intelligent well for pumping-recharging groundwater. A precipitation pipe is buried below a well casing in a well hole, a permeable sand-free pipe is connected above the precipitation pipe, a water pumping pipe and a liquid-gas double-medium side flushing pipe are arranged in the well casing, the bottom of the water pumping pipe is connected with a water pump, and the top end of the water pumping pipe is externally connected to a polluted underground water treatment facility. The top end of the liquid-gas double-medium side flushing pipe serving as a recharge device is connected with a tee joint, and the two ends of the tee joint are connected with an air compressor and a treated standard underground water collecting device through pipelines respectively. High-pressure air can be used for flushing the pipe wall before recharge to guarantee smooth recharge, pressurization and permeation are carried
