摘　　要：工程设计采用集气罩的方式对生物反应池进行密闭,将臭气收集后集中进行处理。在生物反应池中间采用钢桁架的方式进行分隔,以此形成集气罩的承载平台。对运行状态下生物反应池上钢桁架吊装技术进行了总体说明,对特定位置滑移装置的设计和实施进行了描述,最终整个安装过程未对运行造成影响,可给类似工程提供参考。The method of gas collecting hood is used in the engineering design to close the biological reaction tank.The odor is collected,and then treated centrally.The method of steel truss is used in the middle of biological reaction tank for separation so as to form the load bearing platform of gas-collecting hood.The steel truss hoisting technology on the biological reaction tank under operation is generally described.The design and construction of sliding devices at the specific positions are introduced.Finally,the whole installation process does not affect the operation,which can be referred for the similar projects.
