Shizuishan City, Ningxia

Project location: Shizuishan City, Ningxia

Processing scale: 60000 tons/day

Effluent standard: upgraded from national second level standard to national first level A standard

Solution: Adopting micro exposure A ² The original feasibility study design scheme for O process+fully automatic multifunctional biological filter optimization. By tapping into the potential of the biological pool and adding new capacity to the biological pool, it ultimately meets the discharge requirements of the national first-class A standard, with a total retention time of no more than 11 hours for biochemical anaerobic, anaerobic, and aerobic processes.

Wastewater treatment engineering process: coarse and fine grids+aerated sand settling+micro aeration A ² O biological reaction tank+coagulation sedimentation+flowing bed biofilter+contact disinfection
