Microbial fuel cells (MFCs) have attracted much attention due to their ability generate electricity while treating wastewater. The performance of a double-chamber MFC with simultaneous nitrification and denitrification (SND) in the cathode for synthetic high concentration ammonia wastewater was investigated at different dissolved oxygen (DO) concentrations temperatures. results showed that electrode traditional heterotrophic co-existed chamber. Electrode by aerobic bacterium (ADB) is...
Modeling is helpful for predicting nitrous oxide (N2O) accumulation and verifying the production mechanisms in wastewater treatment. A model that integrates two pathways N2O by ammonium-oxidizing bacteria (AOB) under extremely low dissolved oxygen (DO) conditions was proposed this work. In new model, a major improvement of previously published models made to omit intermediary compounds nitroxyl (NOH) nitric (NO) both pathways, aiming reduce parameters calibration The calibrated validated...
The characteristics of N2O emissions from an anaerobic/aerobic/anoxic (A/O/A) sequencing biofilm batch reactor (SBBR) were investigated under different influent COD/nitrogen (C/N) ratios (from 1-4). Results indicated that the C/N affected quantity polyhydroxybutyrate (PHB) and residual organic substances after anaerobic period, resulting in largest emission during aerobic period occurred at a 2. Moreover, anoxic PHB-driven denitrification rapid decline dissolved concentration nitrite...
In this study, a laboratory-scale sequencing biofilm batch reactor (SBBR) was employed to explore fast start-up of completely autotrophic nitrogen removal over nitrite (CANON) process. Partial nitrification achieved by controlling free ammonia concentration and operating at above 30 °C; then the immediately operated with alternating periods aerobiosis anaerobiosis start anammox The CANON process successfully in less than 50 d, total-nitrogen efficiency rate were 81% 0.14 kg-N m−3 d−1...
An anaerobic/oxic/anoxic sequencing batch biofilm reactor (A/O/A SBBR) was tested to treat carbon-limited wastewater without external carbon addition. Simultaneous nitritation–denitritation in the oxic period and poly-hydroxybutyrate (PHB)-driven denitritation anoxic were implemented A/O/A SBBR. A high total nitrogen (TN) removal efficiency of 95.97 ± 2.85% achieved, which 57.62 4.43% removed during aerobic 39.00 4.07% period. Simultaneously, 15.47 2.65% TN emitted as nitrous oxide (N2O),...
A single sequencing batch reactor (SBR) with an operating mode of anaerobic/oxic/anoxic (A/O/A) was developed to determine a simpler process recover nitrous oxide (N2O) from synthetic wastewater containing ammonia and glucose. This SBR system initiated in A/O implement nitritation (ammonia nitrite) then switched A/O/A mode. Using measurements the dissolved N2O concentration release rate, total production conversion rate were calculated reveal potential producing recovering extended anoxic...
