摘要: Abstract An anoxic/aerobic membrane bioreactor (MBR) was applied to simultaneous removals of nitrogen and carbon from food processing wastewater in a laboratory scale experiment. By continuous runs under appropriate operational conditions, COD, NH4+ N TN removal over 94, 91 74%, respectively. The anoxic reactor aerobic MBR contributed 40–63 29–46% COD removal, 31–43 47–64% Nitrification the could be enhanced by adding some carriers for growth adhesive biomass when system operated at shorter sludge retention time (SRT). maximum volumetric loadings as high 3.4 kg COD m−3 day−1 1.26 kg N m−3 day−1 were achieved. Measurement results activity nitrification consistent with effluent concentration change.
