摘　　要：靖江市华汇城市污水处理有限公司扩建工程采用改良型A2O+反硝化滤池工艺作为主体工艺,其中改良型A2/O池设计了两段缺氧区以强化脱氮效果,再以反硝化滤池作为保障措施,进一步确保总氮稳定达标。污泥处理采用重力浓缩+带式压滤+热干化处理工艺,处理后的含水率低于40%,再运往热电厂进行焚烧处置。主要介绍了工程的工艺流程、设计参数,总结并分析了工艺的技术特点及经验体会。Modified A2/O and denitrification filter were applied in the expansion project of Jingjiang Huahui Urban Sewage Treatment Co. Ltd. Two-stage anoxic zone was designed to strengthen the denitrification effect in the modified A^2/O tank. Denitrification filter was designed as the safeguards to ensure TN reaching the requirement of the standard. Gravity thickening/belt filter press/thermal drying treatment process was used in sludge treatment, and the sludge with moisture content of less than 40% after treatment was transported to thermal power plant for incineration disposal. The determination of process flow and design parameters of this project were introduced, and the technical characteristics and design experience of the project were summarized and analyzed.
