NOVELTY - High-temperature aerobic treatment of municipal sludge involves uniformly mixing dehydrated sludge and reflux clinker; transporting the mixture to a compost storehouse and uniformly distributing materials; further mixing the materials to rapidly evaporate water vapor and reduce water content of compost; controlling aeration; and discharging materials with water content of 25-50%, returning one part of reflux clinker to the mixing stage and using the other part as nutrition for soil, and biofiltering collected smelly gas and discharging.    USE - Process for high-temperature aerobic treatment of municipal sludge (claimed).    ADVANTAGE - The process directly uses reflux clinker, does not add conditioners and does not need straw, sawdust, mushroom slag and peanut shells; has high fermentation temperature, short composting period and high mechanical automation; enables complete degradation and generates less bad odor; and realizes harmlessness, stabilization and reclamation of municipal sludge.    DETAILED DESCRIPTION - High-temperature aerobic treatment of municipal sludge involves:    (A) uniformly mixing dehydrated sludge with water content of 75-85% and reflux clinker with water content of 25-50% at weight ratio of 1:1 to 1:0.4 to obtain a mixture with water content of 45-65%;    (B) transporting the mixture to a compost storehouse via a feed belt connected to discharging port of mixer, and uniformly distributing materials using fabric system;    (C) further mixing the materials via turning machine to rapidly evaporate water vapor and reduce water content of compost;    (D) using aeration system to circulate oxygen in inner part of compost, collect smelly gas, and prevent lower-temperature outer air from entering to maintain high temperature of compost in winter; and    (E) transporting the materials to storehouse discharge part, discharging materials with water content of 25-50%, returning one part of reflux clinker to the mixing stage and using the other part as nutrition for soil, and biofiltering collected smelly gas and discharging.
