Abstract EN
As a new category of persistent organic pollutants, polybrominated diphenyl ethers (PBDEs) have become ubiquitous global environmental contaminants.
No literature is available on the aerobic biotransformation of decabromodiphenyl ether (BDE-209).
Herein, we investigated the interaction of PBDEs with aerobic granular sludge.
The results show that the removal of BDE-209 from wastewater is mainly via biosorption onto aerobic granular sludge.
The uptake capacity increased when temperature, contact time, and sludge dosage increased or solution pH dropped.
Ionic strength had a negative influence on BDE-209 adsorption.
The modified pseudo first-order kinetic model was appropriate to describe the adsorption kinetics.
Microbial debromination of BDE-209 did not occur during the first 30 days of operation.
Further study found that aerobic microbial degradation of 4,4′-dibromodiphenyl ether happened with the production of lower BDE congeners.
