【期刊论文】Anoxic degradation of nitrogenous heterocyclic compounds byacclimated activated sludge

Batch experiments were conducted to investigate anoxic biodegradation of five refractory nitrogeneous heterocyclic compounds,i.e. pyridine, indole, quinoline, isoquinoline, 2-methyl quinoline, in coke plant wastewater. These compounds were effectivelydegraded by the denitrifiers in acclimated activated sludge within 60 h. The degradation rate was dependent upon chemicalstructures in the order: pyridine>indole>quinoline>2-methyl quinoline_isoquinoline. Denitrification was a zero-orderreaction, and the denitrification rate of individual compounds had a linear relationship with its corresponding molecularconnectivity index.

Coke-plant wastewater was treated by an anaerobic-anoxic-aerobic (A1-A2-O) biofilm system and an anoxic-aerobic (A/O) biofilm system, respectively. At same or similar levels of hydraulic retention time (HRT), the two systemshad almost identical chemical oxygen demand (COD) and NH3 removals, but a different organic-N removal. Set-up ofan acidogenic stage benefited for the removal of organic-N and the A1-A2-O system was more useful for total nitrogenremoval than the A-O system. HRT did not have a substantial effect on the COD and NH3–N removal efficiencies, butconsiderably influenced the organic-N removal and distribution of oxidized nitrogen in the final effluent. The GC/MSanalysis demonstrated that some refractory compounds were decomposed at the acidogenic stage and resulted in theproduction of some intermediates, which were more readily degraded in the subsequent aerobic stage. Hence, the A1-A2-O system had better effluent quality than the A-O system in terms of effluent composition.

【期刊论文】NP1EC Degradation Pathways UnderOxic and Microxic Conditions

(NP1EC) and the conditions favoring dicarboxylated alklyphenolethoxyacetic acid (CAnP1EC; wheren) the number ofaliphatic carbon atoms) formation were studied in oxicmicrocosms constructed with organic carbon-poor soil fromtheMesasoil aquifer treatment (SAT) facility (Arizona)andpristineorganic carbon-rich sediments from Coyote Creek (California). Results suggest that the availability of dissolved oxygendetermines the dominant biodegradation pathway; ethercleavage and the formation of NP is favored by oxic conditions, while alkyl chain oxidation and the formation of CAP1ECs isfavoredundermicroxic conditions. In theMesamicrocosms,para-NP1EC was transformed to para-nonylphenol (NP) beforebeing rapidly transformed to nonyl alcohols via ipso-hydroxylation.In the Coyote Creek microcosms, large quantities of CAP1ECswere observed. Initially, CA8P1ECs were the dominantmetabolites, but as biodegradation continued, CA6P1ECsbecame the dominant metabolites. Compared to the CA8P1ECs,the number of CA6P1ECs peaks observed was small (<6)even though their concentrations were high. Several novelmetabolites, tentatively identified as 3-alkylchroman-4-carboxylicacids (with alkyl groups ranging from C2 to C5), were formedin the Coyote Creek microcosms. These metabolites arepresumably formed from ortho-CAP1ECs by intramolecularring closure.

A laboratory-scale anaerobic-anoxic-aerobic (AAA) activated sludge wastewater treatment system wasemployed to investigate the effects of hydraulic retention time (HRT) and sludge retention time (SRT)on the removal and fate of di-(2-ethylhexyl) phthalate (DEHP). In the range from 5 to 14 h, HRT hadno significant effect on DEHP removal. However, longer HRT increased DEHP accumulation in the systemand DEHP retention in the waste sludge. When SRT was increased from 15 to 25 d, DEHP removal efficiencystayed above 96%. Compared to the removal of only 88% at SRT of 10 d, longer SRT enhanced DEHPdegradation efficiency. The optimal HRT and SRT for both nutrients (nitrogen and phosphorus) and DEHPremoval were 8 h and 15 d. At these retention times, about 71% of DEHP was degraded by the activatedsludge process, 26% was accumulated in the system, 2% was released in the effluent, and 1% remained inthe waste sludge. The anaerobic, anoxic and aerobic reactors were responsible for 15%, 19% and 62% of theoverall DEHP removal, respectively.

【期刊论文】Sorption and degradation of bisphenol A by aerobic activated sludge

Laboratory-scale batch experiments were conducted to investigate the sorption and degradation of bisphenol A (BPA) at _g/L range in an aerobicactivated sludge system. The sorption isotherms and thermodynamics indicated that the sorption of BPA on sludge was mainly a physical processin which partitioning played a dominating role. The values of sorption coefficient Koc were between 621 and 736 L/kg in the temperature range of 10-30℃. Both mixed liquor suspended solid (MLSS) and temperature influenced BPA sorption on sludge. The degradation of BPA by acclimatedactivated sludge could be described by first-order reaction equation with the first-order degradation rate constant of 0.80h−1 at 20℃. The decreaseof initial COD concentration and the increase of MLSS concentration and temperature enhanced BPA degradation rate. The removal of BPA in theactivated sludge system was characterized by a quick sorption on the activated sludge and subsequent biodegradation.
