摘　　要：水热改性(Hydrothermal Modification),是指把含水率很高的污泥密闭加热到一定的温度和压力,并维持一段时间,以破坏其中的细胞结构并促使大分子有机物发生水解的过程。经过水热改性处理后的生物质,细胞结构被破坏,高分子有机物断裂为较小的分子。残留的颗粒物由于细胞结构被破坏,胞内水、间隙水和毛细水转化为自由水而变得更易脱水。Hydrothermal modification refers to the process of heating the sludge with high water content to a certain temperature and pressure and maintaining it for a period of time to destroy the cell structure and promote the hydrolysis of macromolecular organics.After hydrothermal modification,the cell structure of biomass is destroyed,and the macromolecular organic matter breaks into smaller molecules.In addition,the residual particles become more easily dehydrated due to the destruction of cell structure and the conversion of intracellular water,interstitial water and capillary water into free water.
