The invention discloses a municipal solid waste coordinative incineration power generation system which comprises a household refuse incineration power generation system. The household refuse incineration power generation system comprises an incineration unit and further comprises a municipal sludge drying unit, wherein heat generated by incineration is absorbed by a waste heat boiler of the incineration unit to generate steam and the steam is conveyed to a heat energy use unit for generating power; the municipal sludge drying unit receives municipal sludge; the municipal sludge is indirectly heated and dried through the steam passing the heat energy use unit; a refuse receiving, storing and conveying unit is further used for receiving, storing and conveying the dried sludge; and the incineration unit is further used for receiving and incinerating the dried sludge. The municipal solid waste coordinative incineration power generation system has the beneficial effects that the engineering floor space is saved to a great extent, equipment investment cost and operation cost are reduced, the municipal solid waste resource utilization degree is increased, and the generating capacity and the operation stability of the household refuse incineration power generation system are improved; the pollutant emission requirement is much higher that the decentralized treatment execution standard; and the emission of pollutants is reduced.
