摘　　要：滤布滤池作为城镇污水处理出水SS稳定达标的重要保障单元,受规模小、成本低和无人值守等条件限制,在小城镇污水处理中的应用较少。通过对滤布滤池的结构、滤布选择、喷头布局优化、反洗模式优选等研究,研发了一种适用于小城镇污水处理的新型滤布滤池,能够以模块化灵活耦合于小城镇污水生物处理系统中,通过规模为50 m3/d的滤布滤池样机的生产性试验验证,滤池运行稳定,出水SS能够稳定在10 mg/L以下,可满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。The cloth filter is an important unit to ensure the stability of effluent in the urban wastewater treatment; however, the small scale, low cost and unattended operation have limited its application in small-town wastewater treatment. In this paper, a new cloth filter suitable for small-town sewage treatment was developed through the research of the cloth filter structure, the selection of the filtration cloth, and the optimization of the nozzle layout and the backwash mode. The new cloth filter could be flexibly incorporated into a small-town wastewater biological treatment system. Through the pilot testing, the prototype of the cloth filter steadily processed up to 50 m^3/d. The SS of effluent was controlled below 10 mg/L which had met the first class A standard in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002）.
