Effect of pure oxygen fine bubbles on the organic matter removal and bacterial community evolution treating coal gasification wastewater by membrane bioreactor
Pure oxygen fine bubbles-MBR was developed treating coal gasification wastewater.
•
Organic matter reduction and membrane fouling mitigation were improved in O2-MBR.
•
Less amount of EPS and larger particle size distribution existed in novel system.
•
Pure oxygen with fine bubbles promoted marked evolution of bacterial community.
