core advantage
The water outlet meets the standard and can be directly reused.Combined with biodegradation and membrane separation technology, the effluent is clear and free of suspended solids, and can stably meet the "Urban Wastewater Treatment Plant Pollutant Discharge Standard" Class A standard or the reclaimed water reuse standard.
Highly integrated, buried/above-ground flexible arrangementInitial subsidence, anoxia, aerobic, MBR membrane pool and disinfection pool are highly integrated, and the equipment can be buried underground (the surface can be green/used as a parking lot), which greatly saves floor space.
Highly automated and unattendedEquipped with PLC intelligent control system and remote monitoring, with automatic operation, automatic backwashing, fault alarm and sludge return functions, daily operation and maintenance are minimalist.
Strong impact load resistance and low sludge yieldThe use of high-concentration activated sludge and filler/membrane modules can effectively withstand fluctuations in water quality and quantity, and the discharge of organic sludge is significantly lower than that of traditional processes.
Typical process flow (take A/O + MBR as an example)
The equipment adopts mature biological nitrogen and phosphorus removal and high-efficiency membrane filtration technology:
Process diagram:Sewage → grid well (intercepting large particles) → regulation tank (homogeneous average) → anoxic tank (A tank) → aerobic tank (O tank) → MBR membrane tank/sedimentation tank (sludge backflow to A tank) → disinfection tank → effluent reuse/discharge
Hypoxia Pool (A Pool)Denitrifying bacteria use the organic matter in the incoming water to reduce the refluxed nitrate nitrogen to nitrogen, achieving efficient denitrification.
Aerobic Pool (O Pool)Aerobic microorganisms degrade BOD/COD and convert ammonia nitrogen into nitrate nitrogen.
MBR membrane tank/sedimentation tankSolid-liquid separation was carried out through 0.1 μm PVDF hollow fiber membrane or flat membrane to completely intercept activated sludge and suspended solids.
Disinfection tank: Use chlorine dioxide or ultraviolet disinfection to kill Escherichia coli and then discharge or reuse it up to standard.
