摘　　要：连续式砂滤器集混凝、澄清、过滤为一体,具有可连续运行、无需停机反冲洗、过滤和产水效率高、占地小等优点,广泛用于污水的深度处理和回用。以DynaSand为例,介绍了该种砂滤器的结构和工作原理。同时,从砂滤器最优工作参数、与之配合使用的絮凝剂及与其他工艺联合应用等方面,详细介绍了该种新型水处理设备,分析了其优缺点,并指明了今后的研究重点。The continuous sand filter, which combines coagulation, clarification and filtration, is widely used for wastewater advanced treatment and reuse due to its advantages such as continuous operation, no downtime for backwashing, efficient filtration and water production, small footprint and so on. The structure and working principle of the filter like DynaSand are introduced. The optimum operation parameters of the filter, flocculant used and combined use with other processes are discussed. The advantages and disadvantages of the filter are analyzed, and key points in the future study are outlined.
