摘要：Water structure present in sewage sludge with different moisture content was analyzed by differential scanning calorimeter(DSC). The sharp endothermic peaks that appeared at 6.14 degrees C(95.87%wet basis), 5.22 degrees C(87.20%wet basis), 1.33 degrees C(71.20%wet basis). The calculation results, amount of bound water based on peak temperature and peak area, could account for stick phase of sewage sludge combined with SEM analysis results. Finally,mechanical mechanism of different phases(liquid phase, sticky phase, granule phase) were tentively described by schematic diagrams.
