摘要
城市污水处理厂污泥泥量日益增多,使污泥脱水设备处理能力逐渐低于设计值,未能及时处理的污泥将对环境造成污染危害。基于我国污泥处理处置中存在的问题,分别围绕化学法、物理法和生物法3种预处理调理技术详细介绍了国内应用较多的污泥深度脱水技术研究进展。结合国内外污泥深度脱水新技术,针对目前我国国情对污泥深度脱水技术的应用前景和发展趋势做出展望。
Recently, the sludge in wastewater treatment plant gradually increased which made the working capability of dewatering equipment lower than that of the design value, and thus resulted in seriously environmental problems. In order to deal with the problems existed in sludge treatment and disposal, the deep dewatering process of sludge in urban wastewater treatment plant was introduced, according to chemical, physical and biological conditioning in detail. Furthermore, the characteristics and feasibility of new deep dewatering processes and the trends and applications in China were proposed.
