Advanced treatment of coal chemical reverse osmosis concentrate with three-stage MABR

Abstract

A MABR system was constructed to treat coal chemical reverse osmosis concentrate without an external carbon source.

Enhanced carbon and nitrogen removal in an integrated anaerobic/anoxic/aerobic-membrane aerated biofilm reactor system

“…Chloroexi (8.86%, 2.74, 10.86%), Saccharibacteria (2.24%, 0.89%, 3.76%), Nitrospirae (1.3%, 2.45%, 2.68%), and Firmicutes (3.25%, 0.86%, 1.94%) varied greatly among the three samples. Proteobacteria, Bacteroidetes, and Chlorobi (1.82%, 2.31%, 2.28%) are denitrifying bacterial ora, 38,39 and their contents in the A 2 /O-MABR system were higher than those in the A 2 /O system, suggesting that the biolm strengthened the removal of the TN. Firmicutes had the function of sustaining the stability of the system, 36 and its content in A 2 /O-MABR system was signicantly higher than that in A 2 /O system.…”
