摘　　要：污泥脱水、输送及储存系统是污泥处理处置工程的重要组成部分,以南宁某项目为例,介绍了污泥脱水工艺、进泥设备、加药系统及泥水分离阀的设计及优化建议;介绍了污泥输送螺旋、缓存料斗及料位检测的工程应用特点,提出一体化破拱装置,详述污泥输送泵及其故障处理方式;介绍了污泥储存系统的管道、入料口的设计要点,滑架破拱装置的设计优化及其液压系统热平衡分析等。该项目投入运营后,脱水污泥含水率降至80%,污泥的日输送量达到66.85 m^(3)/d,污泥储存系统储存量达到200 m^(3),实现了污泥的减量化生产。最后对该工程进行技术经济分析,为同类项目提供参考。The systems of sludge dewatering,pumping and storage are important for sludge treatment and disposal.The design and optimization suggestion of dewatering process,sludge feeding equipment,dosing system and sludge-water separation valve were introduced through a project of sludge treatment and disposal in Nanning.As to the sludge pumping system,the technical characteristics of screw conveyor,sludge bin and material level detection were also discussed.Furthermore,the integrated arch breaker device were put forward,and the sludge pumping features and its pumping failure-solution were described in details.With regard to the sludge storage system,the design points of piping and feeding-inlet,the optimization of arch breaker device and its heat balance calculation of the hydraulicallydriven system were analyzed.Since the project was put into operation,the water content of sludge was decreased to 80%,the daily transportation capacity of sludge reached 66.85 m^(3)/d and its sludge storage capacity was more than 200 m^(3).The sludge reduction was realized.Finally,the techno-economic analysis was conducted,which could provide reference for the similar projects.
