摘要	Hydrothermal treatment is a benefit process for the mass reduction, stabilization and recycling of biosolids, however, the mutual relation between mass transfer and physicochemical property are still unclear. Our work undertook the hydrothermal treatment of biosolids in batch reactors under different temperature ranged from 180-300°C. Result showed that protein and carbohydrate were the primary macromolecular compounds in initial hydrothermal reaction, and protein was richer but less stable than carbohydrate. Temperature is a key factor affecting the organic matter transferring process between solid and liquid phase, reaction efficiency markedly reduced when temperature drop to 180°C. Morphologic change of biosolids was observed, including a rapid dewatering process in initial reaction and disintegration process to small size particles. © (2014) Trans Tech Publications, Switzerland.
