Municipal sludge green energy-saving recycling brick making process

The invention discloses a municipal sludge green energy-saving recycling brick making process, and relates to the technical field of building material manufacturing, the municipal sludge green energy-saving recycling brick making process comprises the following steps: S1, sludge conditioning: adding functional fiber RPFA and a flocculant into sludge; the conditioning time is 10 to 120 minutes; s2, raw material treatment, wherein coal gangue, bauxite tailings, building waste residues and shale are smashed, and the fineness is controlled to be 1-3 mm; s3, mixing the materials: mixing the materials obtained in the steps S1 and S2, and uniformly stirring; s4, blank making: aging the mixture obtained in the step S3; and S5, brick making: drying and roasting the green bricks aired in the step S4 by using a drying kiln and a tunnel kiln, and cooling to obtain a finished product. In the sludge conditioning process, the functional fiber RPFA short fiber is added to serve as a sludge framework material, the electric ch
