description The invention discloses a corrugated medium produced from waste paper papermaking sludge as well as a production method of the corrugated medium. In the process for producing the corrugated medium from waste paper used as a raw material, primary sludge with the paper pulp fiber mass ranging from 0.5% to 2%, biochemical sludge with the paper pulp fiber mass ranging from 0.5% to 1%, cationic starch with the paper pulp fiber mass ranging from 0.1% to 1% and cationic polyacrylamide with the paper pulp fiber mass ranging from 0.01% to 0.08% are added to a paper-making machine pulp tank and evenly mixed, the corrugated medium is produced after net loading, paper-making with pulp, pre-drying, surface sizing with surface sizing starch and after-drying, and the consumption of the surface sizing starch is 0.2-1 time the total amount of the primary sludge and the biochemical sludge. The waste paper papermaking sludge is used for producing the corrugated medium, waste paper raw material consumption can be reduced, the production cost can be reduced, and the economic benefit is better; meanwhile, the yield of solid waste can be greatly decreased, the pollutant end treatment cost can be reduced, and the environmental benefit is significant.
