污泥处理与处置问题是世界性难题,而无论采取何种处置方式,污泥的脱水干化都是其必要前提。对现有的污泥脱水干化技术进行了研究,分别介绍了污泥浓缩技术、脱水技术和干化技术,详细阐述了其各自的现有技术手段、达到的干化效果和研究进展。并指出物理化学调理联合机械脱水是目前主流的脱水技术,而热干化是最为成熟的干化技术。重点描述了目前工程上应用比较多的工艺技术,以及污泥的脱水干化对于污泥农用、燃料化、焚烧和填埋等处理处置方式的积极作用。

The treatment and disposal of sludge are the present challenges of the world. Dewatering and drying are the essential pretreatment for any sludge disposal procedure. The present methods were investigated,including thickening,dewatering,and drying, in order to enhance the properties of dewatering and drying of sludge. Several important characteristics were elaborated,in which methods,effects,and the research progresses of those three methods were involved.It is pointed out that the physical-chemical conditioning combined with mechanical dewatering is the most popular dewatering technology,while...
