- Abstract:
- To remedy the Nanming River system, construct an ecological barrier in the upper Yangtze River and solve the problem of sewage treatment in the downtown, the first project of ultra-deep foundation pit underground reclaimed water plant combined with upper comprehensive complex was constructed in Liuguangmen and Guiyi reclaimed water plants in Guiyang. The project integrated municipal infrastructure, ecological environment and urban architecture. The stadium, sport and cultural complex and commercial complex were built on the ground, while the commercial complex, parking lot and wastewater treatment plant were built underground. The core treatment process of Liuguangmen reclaimed water plant(12×104 m3/d) is MBR, which adopts the process of medium grid and fine grid, aerated sand sedimentation tank, membrane grid, traditional activated sludge biochemical tank, MBR and UV disinfection. The main indicators of effluent meet the surface water class Ⅳ standard, and the effluent is discharged into Guancheng River and finally used as ecological water supplement of Nanming River.
