The invention discloses a solid waste treatment system based on a coal-fired boiler, which is characterized in that one end of a grate furnace is provided with a grate furnace wall, the other end of the grate furnace is provided with a high-density solid waste outlet, and the high-density solid waste outlet is communicated with a high-density solid waste inlet of a hearth; a pyrolysis gas outlet of the grate furnace is communicated with a pyrolysis gas reburning nozzle of the hearth, a low-density solid waste outlet of the grate furnace is communicated with an inlet of the coal mill, a medium-density solid waste outlet of the grate furnace is communicated with the inlet of the coal mill through the primary smashing system, and an outlet of the coal mill is communicated with the pulverized coal and solid waste coupling burner on the hearth. And an outlet of the low-speed induced draft fan, an outlet of the medium-speed induced draft fan and an outlet of the high-speed induced draft fan are respectively communi
