摘　　要：由于对TN、NH_(3)-N、SS、TP均有稳定良好的去除作用,反硝化滤池被广泛应用于污水厂深度处理中。硫自养反硝化滤池因在药剂成本、污泥处置成本和低碳生产中的优势而成为当下研究热点,其复合滤料兼具过滤截留、挂膜材料和电子供体三种功能。本文系统地论述了以S^(0)、S^(2-)、S_(2)O_(3)^(2-)为无机电子供体的硫自养反硝化滤池复合滤料的材料基本特性、污染物去除反应机理、优缺点、改性研究及工程实例等,最后对未来的研究方向进行展望,以期为后续的硫自养反硝化滤池工程设计和复合滤料研究提供参考。Due to their stable and good removal effects on TN,NH_(3)-N,SS,and TP,denitrification filters are widely used in advanced treatment of sewage plants.The sulfur autotrophic denitrification filter has become a current research hotspot due to its advantages in drug cost,sludge disposal cost,and low-carbon production.Its composite filter material has three functions:filtration interception,membrane hanging material,and electronic donor.This article systematically discusses the basic material characteristics,pollutant removal reaction mechanism,advantages and disadvantages,modification research,and engineering examples of sulfur autotrophic denitrification filter composite filter media using S^(0),S^(2-) and S_(2)O_(3)^(2-) as inorganic electron donors.Finally,future research directions are discussed,in order to provide reference for the subsequent design of sulfur autotrophic denitrification filter media and research on composite filter media.
