Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 4,   Pages 531-538 doi: 10.1007/s11783-014-0629-1

Abstract: prepared by loading nanosized ferric oxyhydroxide (FO) on anion exchanger resin for the removal of phosphateBatch adsorption experiments revealed that higher temperature (313K), higher initial phosphate concentration(50 mg·L ) and lower solution pH (pH value of 2) would be more propitious to phosphate adsorption.Competition effect of coexisting anions on phosphate removal can be concluded as sulfate>nitrate>chlorideFreundlich isotherm model can describe the adsorption of phosphate on FOAE more accurately, which indicated

effects of excessive anaerobic reaction time on anaerobic metabolism of denitrifying polyphosphate- accumulating

Gang GUO, Yayi WANG, Chong WANG, Hong WANG, Mianli PAN, Shaowei CHEN

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 4,   Pages 616-624 doi: 10.1007/s11783-013-0505-4

Abstract: The short-term effect of anaerobic reaction time (AnRT) (i.e., 90, 120 and 150 min) on the denitrifying phosphorus (P) removal performance and N O production was examined using a denitrifying enhanced biologic phosphorus removal (EBPR) sludge acclimatized with mixed acetate (HAc) and propionate (Pro) (in the molar ratio 3∶1) as carbon sources. The results showed that when the AnRT was prolonged from 90 to 150 min, the anaerobic polyhydroxyalkanoate (PHA) synthesis was decreased by 15.3%. Moreover, the ineffective PHA consumption occurred in anaerobic phases and contributed to an increased accumulation and higher free nitrous acid (FNA) concentrations (≥0.001–0.0011 mg HNO -N/L) in the subsequent anoxic phases, causing a severe inhibition on anoxic P-uptake and denitrification. Accordingly, the total nitrogen (TN) and total phosphorus (TP) removal efficiencies dropped by approximately 6.3% and 85.5%, respectively; and the ratio of anoxic N O-N production to TN removal increased by approximately 3.8%. The fluorescence in situ hybridization (FISH) analysis revealed that the sludge was mainly dominated by (62.0% (SE = 1.5%)). In conclusion, the short-term excessive anaerobic reaction time negatively impacted denitrifying P removal performance and stimulated more N O production, and its effect on P removal was more obvious than that on nitrogen removal.
