Summary:The present invention discloses a sludge drying and sewage treatment method. The sludge drying and sewage treatment method comprises the following steps: metering wet sludge, and loading the wet sludge into a wet sludge bin for storage; adding 110-120 ppm of polyacrylamide to the sludge in the wet sludge bin according to the mass of sludge, adding 30-35% of sawdust according to the mass of pure dry sludge, stirring the mixture uniformly and sending the mixture into a dryer to perform continuous drying; and filtering sewage generated by a sludge drying system through a grill channel to remove large pieces of debris, and the sewage entering a primary water hoisting shaft to adjust a pH value, then the sewage entering a water quality adjusting pool to adjust the water quality and remove nitrogen and phosphorus. The method provided by the present invention is good in effect of removing nitrogen and phosphorus in the sewage, and is simple in technology. The water content of the sludge after sludge drying treatment
