摘　　要：厌氧消化是我国解决污泥处理处置的一条重要技术路线,从国内现有污泥消化项目的整体运行情况看,却不是很乐观。除了泥质的客观因素外,工艺设计、设备选型优化对于提升消化系统整体功能同样有潜可挖。对消化池设备和仪表的配置及选型进行系统性地说明,针对大型厌氧消化池的管道设计,提出消化池内外管路和管路之间连接阀门布置的方式。借助多功能阀门组的设置,满足从调试快速启动到后期稳定运行的多种工况要求。就消化池实际运行中经常遇到的泡沫、浮渣等问题,选择相应的辅助非标设备并对这些设备的功能和设置方式进行描述,以期对后期厌氧消化池的设计、设备选型和运行提供技术借鉴。Anaerobic digestion process is one of the most important technology for sludge treatment in China.However,the operation of existing sludge digestion projects is not doing very well.Despite of sludge quality,there is also a high potentiality to improve the efficiency of the digestion system by optimization of design and equipment selection.In this study,the selection and configuration of digestion equipment and the instruments were systematically illustrated.The arrangements of piping inside and outside the digester as well as the valves between the pipes were proposed for the piping design of large-sized anaerobic digestion tanks.With the help of the multi-functional valve group,it could satisfy the various requirements under different working conditions from the fast start-up to later stable operation period.Meanwhile,with regard to the foam and scum issues frequently encountered during the operation,the function and layout of related auxiliary non-standard equipment were also described as to provide the technical references for the design,equipment selection and the operation of anaerobic sludge digestion system in the future.
