英文摘要 | Haloalkaliphilic microorganisms were used to treat wastewater from adsorption alkaline solution of flue gas characterized by high pH and salinity. Lactate, glucose, methanol, ethanol, formate, and acetate were used to investigate the effect of different electron donors on the performance of haloalkaliphilic sulfate-reducing bioreactors. At pH 9.5 and 1.0 M of Na+, the optimum electron donor was found to be ethanol with the shortest lag period (31 days) and the highest sulfate removal rate (8.60 +/- 0.129 kg m(-3) d(-1)). Bioreactors were stable after they were successfully started up. High sulfide concentration (3294 +/- 18.8 mgl(-1)) did not inhibit the activity of sulfate-reducing bacteria (SRB). Microbial degradation patterns related to sulfate reduction of different electron donors were determined. Oxidation process of propionate was coupled with sulfate reduction process in the lactate- and glucose-fed bioreactor. Glucose can be directly utilized by haloalkaliphilic SRB. The pathway of ethanol to pyruvate and Wood-Ljungdahl pathway were found in the ethanol- and formate-fed bioreactor, respectively. Some haloalkaliphilic SRB of the complete oxidation type may be present in the formate-fed bioreactor. (C) 2014 Elsevier B.V. All rights reserved. |
