Abstract

The experiment used the iron carbon micro-electorlysis combined with sequencing batch biofilm reactor(iron carbon micro-electorlysis-SBBR) process to treat acrylic fiber wastewater. The iron carbon micro-eletrolysis-SBBR process could make the COD of acylic fiber wastewater from 550~700mg/L down to 140~165mg/L or so, and the removal rate of DMAC and acrylonitrile could respectively reach to 97.8% and 100%. After long-term of operation, it was observed that the predominant microorganisms immobilized on the SBBR carriers were bacillus, filamentous fungus, and a small amount of coccus.
