污水处理厂污泥消化系统设计及运行

An Elementary Introduction to Design and Operation of Sludge Digestion System in Sewage Treatment Works

介绍了郑州和天津的2座污水处理厂污泥消化系统(包括设计污泥量及含水率、污泥投配系统、消化池型及参数选择、搅拌系统、沼气系统、热水循环系统)的设计。对其中郑州某污水处理厂的运行情况进行分析,总结其存在的问题及从中应吸取的经验。可供污水处理厂污泥消化系统的设计参考。

Introduced hereby is the sludge digestion system in the sewage treatment works in Zhengzhou and Tianjin respectively,including the design of sludge quantity and water content,selection of type of digestion tank and parameters,sludge dosing system,stirring system,methane system and hot water circulation system,with the analysis of the operation of a sewage treatment works in Zhengzhou,and a summary of the problems there and the experience to be learned as a reference for similar works.
