- Abstract:
- Flood prevention design is of top priority for design of underground sewage treatment plant (station). In view of the existing problems in flood prevention design, combined with the design case of Erlangmiao sewage pretreatment station of Dadonghu sewage deep tunnel project in Wuhan, this paper introduces that by setting low and high weir at the outlet of lift pump, switching between high and low weir with quick closing gate, as well as setting overflow lift pump and corresponding anti-backdown gate at the end of the pretreatment station, the underground box can avoid flooding caused by the excessive inflow in the rains and the downstream facilities accident, and the sewage treatment system can operate normally and continuously at the same time.
