The invention provides a landfill leachate treatment system and method. The treatment system comprises a raw water tank, a wastewater heat exchanger, a wastewater heater and an oxidation reactor which are sequentially connected, wherein a material inlet, a material outlet, a heat source inlet and a heat source outlet are formed in the wastewater heat exchanger; oxidized water from the oxidation reactor enters the wastewater heat exchanger from the heat source inlet, the heat source outlet is connected with a finished product tank, the finished product tank is connected with membrane filtration equipment so as to concentrate landfill leachate, the material inlet is connected with the raw water tank, and the material outlet is connected with the wastewater heater; a micro-interface generating system for dispersing crushed gas into bubbles is arranged on the outer side of the oxidation reactor. According to the treatment system, after the micro-interface generation system is arranged, the contact of a reaction p
