Abstract：Research purposes: The sewage from the toilet in underground building often needs to be drained into the municipal drainage system through sewage pump. During the drainage process, the sewage often gives off the peculiar smell which hazards environment. In this paper, the introduction is given to the application of enclosed lifting device for sewage in metro and the calculation method, difficult points and countermeasure for it are presented for the purpose of providing the reference to the similar works.
Research conclusions: It is feasible to apply the enclosed lifting device for sewage in metro, which can improve the environments of metro and underground buildings with perfect social and economic benefits.
