Bioaugmentation treatment of bromoamine acid wastewater with Sphingomonas sp. FL
One effective bromoamine acid (BAA) degrading strain FL was isolated previously with the ability to use BAA as the sole source of carbon and energy. The strain FL was applied in a combined process of microelectrolysis (ME) and biological aerated filter (BAF) to treat the bromoamine acid wastewater, and the treatment efficiency was investigated. It was shown that when the influent COD_(cr) was lower than 1000 mg L~(-1), and the total hydrolytic retention time (HRT) was 37.7 h, the removal rate of chrominance and COD_(cr) could reach 95.3％ and 77.3％ respectively. Most of the chrominance was removed by the ME treatment, while the removal of COD_(cr) is mostly owned to the BAF treatment. After long-term contact with the BAA wastewater, the strain FL became one of the predominent species in BAF. When the system was subjected to hydraulic loading shock, the strain FL ensured the efficient removal of chrominance and BAA.
