Concept:High-efficiency equipment for high-concentration organic wastewater. Anaerobic microbes decompose organics into methane & CO₂, realizing sludge reduction and biogas recovery. Made of FRP, anti-corrosion carbon steel or concrete.
Functions:
Treat wastewater with COD ≥1500mg/L, cut COD by over 80% for subsequent aerobic treatment
No aeration needed, power consumption only 10%-15% of aerobic process, far less residual sludge
Recover biogas (70% methane) for heating or power generation
Main Types & Principle:Three-stage anaerobic digestion: Hydrolysis → Acidification → Methanation
UASB Upflow Anaerobic Sludge Bed: Integrated three-phase separator, widely used for most organic wastewater
IC Internal Circulation Reactor: Biogas-driven internal circulation, high load, small footprint for super high-concentration wastewater
UBF Composite Reactor: Sludge bed + bio-filler, stable effluent
Advantages:High volumetric load, compact size; Biogas energy recovery; Low e…
