- Abstract:
- The design scale of an underground sewage treatment plant with integrated layout in Qingdao is 30×104 m3/d, and the area of the underground box is about 10.7×104 m2. The large number fire compartments are divided according to the plant buildings, which is not conducive to the operation and management of the sewage treatment plant. In addition, there are many buildings on the ground, which affects the construction of the ground landscape park. The design divided the operation platform of the underground first floor water tank into an integral fire compartment. The fire compartments were set up in key areas for inspection and maintenance such as equipment rooms and driving passages on the first floor underground according to the requirements of the specifications, and the area of the fire compartments was expanded by setting an automatic fire extinguishing system. No fire compartment was divided in the underground second floor. The fire protection of the underground second floor pipe gallery area was designed according to the urban utility tunnel. The optimized design scheme was evaluated through the assessment such as fire scenario analysis, fire spread and smoke flow status analysis and personnel evacuation analysis, so as to provide reference for the subsequent fire protection design of underground sewage treatment plant.
