The utility model provides an energy-saving soil and groundwater remediation multiphase extraction system which comprises a multiphase extraction system, a gas-liquid separation device, a liquid treatment system and a gas treatment system, the multiphase extraction system comprises an extraction well and an extraction pump, and the extraction pump is mounted on the upper side of the extraction well; according to the bottom mud drying device, combustion waste heat is used for drying bottom mud, heat energy utilization is facilitated, other energy sources do not need to be used additionally, the dried bottom mud is more convenient to incinerate, and the efficiency of the incineration device cannot be affected by excessive water. The mass of the incinerated bottom mud becomes small, the bottom mud which is not dried and incinerated is directly treated, the treatment cost is high, the mass is reduced after incineration, and the treatment cost is low; in addition, the combustion device can be better controlled to
