Development and Spatial Microstructure Variation of Membrane Foulants in a Hollow Fiber Anaerobic Membrane Bioreactor for Milk Waste and Sewage Sludge Co-treatment

摘要

(1)Milk waste and sewage sludge -fed HF-AnMBR could operate stably for around120 d with the biogas production rate approaching 2.5 ±0.3 L/L/d at optimal OLR 6 g-COD/L/d. (2) Membrane operation performance analysis through membrane fouling revealed that cake layer fouling was the main contribution to the total fouling (70.4%).
