Microwave desorption system for soil

A microwave desorption system for soil, comprising:

• a rectangular housing;
• a microwave heating device located inside and fixed to the rectangular housing and configured to heat a material with a moisture content ranging between 5% and 50% and a particle size not greater than 5 cm;
• a gas treatment device located inside and fixed to the rectangular housing, connected to the microwave heating device, and equipped with a plurality of ultraviolet light sources, wherein the plurality of ultraviolet light sources are configured to emit an ultraviolet light energy to directly decompose and purify a waste gas generated after the microwave heating device heats the material, so that a purified waste gas is released by the gas treatment device;
• and
