Using　cement　kiln　dispose　sludge　from　sewage　plants　can　achieve　the　sludge　stabilization,　harmless,　reduction　and　resource　comprehensive　utilization　purposes.　This　is　Not　only　to　solve　the　problem　of　sludge　treatment　which　is　difficult　to　solve　by　sewage　treatment　plant,　but　also　to　make　full　use　of　the　sewage　treatment　plant　sludge　to　replace　part　of　cement　clinker　production　materials.　And　it　makes　full　use　of　sludge　incineration　emitted　in　the　process　of　low　calorific　value.　Municipal　sludge　contains　more　moisture.　It　is　necessary　to　dry　the　sludge　outside　the　kiln　before　entering　kiln　process.　As　cement　kiln　co-processing,　it　should　be　combined　with　the　characteristics　of　NSP　clinker　production,　it　is　necessary　to　not　only　consider　the　total　energy　consumption　of　the　drying　process,　but　also　the　re-use　of　dried　sludge　heat　value,　as　well　as　consider　the　total　of　water　into　the　kiln　by　drying　sludge　affecting　the　whole　clinker　production　process.　In　this　paper,　with　the　initial　solid　content　20%,　dry　heating　value　3400　cal/g　sludge　as　a　research　object,　the　moisture　morphology,　thermal　characteristics,　drying　technological　parameters　and　composition　of　water　after　drying　in　sludge　were　analysed.　This　issue　combines　sludge　drying　with　cement　kiln　disposal,　which　can　not　only　solve　the　heat　and　odor　problem　during　the　individual　sludge　drying　process,　but　also　provide　a　theoretical　basis　for　cement　kilns　co-disposal　of　municipal　sewage　sludge　to　achieve　the　purposes　of　sludge　stabilization,　harmless,　minimization　and　resource　utilization.　©　2017　Trans　Tech　Publications,　Switzerland.
