Solid waste incineration treatment device and treatment method

The invention discloses a solid waste incineration treatment device and method, and belongs to the technical field of waste treatment, the solid waste incineration treatment device comprises a rack and a bottom cylinder fixedly connected to the inner wall of the rack, a treatment assembly is arranged at the top end of the bottom cylinder, and circulation assemblies are arranged on the two sides of the treatment assembly. By arranging the treatment assembly and the circulation assembly, the treatment assembly can crush solid waste, fragmented materials make more sufficient contact with oxygen, so that combustion is accelerated, meanwhile, a large amount of hot air is generated in a combustion area, circulation is conducted through the circulation assembly, external oxygen-containing air is carried into the device, air is blown from the bottom, and the combustion efficiency is improved. And the treatment assembly crushes and scrapes materials which are completely combusted again, the materials are prevented fro
