Anoxic ferric iron-dependent ammonium oxidation (Feammox) is a novel biological nitrogen removal process that oxidizes to NO 2 -, 3 -or N using iron as the electron acceptor.In this study, Feammox was successfully developed in biofilm reactor sponge Fe source feeding ammonium-containing aerobic water.The results showed NH 4 + oxidized -by Feammox.During 300 d of operation, bioreactor demonstrated an average efficiency and rate 42.3% 32.2 mg L -1 , respectively.Sponge by dissolved oxygen (DO)...
Abstract BACKGROUND N 2 H 4 and NO are the important intermediates of Anammox. The appropriate addition weakens inhibitory effect − on anaerobic ammonium oxidation bacteria ( AnAOB ) activity. long‐term micro‐amounts was investigated in this study. RESULTS A sequencing batch reactor SBR performing Anammox could run stably during . nitrogen removal rate efficiency with were higher than without addition. molar ratio 3 production to NH + MRNN decreased 0.12, significantly lower expected...
Nitrogen oxides in flue gas cause considerable environmental and health problems. In this study, the NO removal through Fe(II)EDTA absorption based anaerobic ammonium oxidation (Anammox) reduction was first evaluated batch tests. The efficiency rate of reached 74.5%–85.4% 1.62–15.48 μmol gVSS–1 h–1 with absorption, respectively. optimal temperature pH for Anammox 30 °C 7.0 range from 25 to 45 6.5 8.0, maximum specific substrate utilization half-saturation constant Fe(II)EDTA-NO were...
Abstract BACKGROUND Ammonia ( NH 3 ) was converted to dinitrogen gas N 2 cooperating between ammonia‐oxidizing bacteria AOB and anaerobic AnAOB with low amounts of nitrous oxide O as the side‐product in completely autotrophic nitrogen removal over nitrite CANON process. Contributions ammonia oxidation (anammox) by nitrifer denitrification for (N) characteristics production were investigated comprehensively this study . RESULTS dominant contributor removal, contributions from nitrifier less...
The kinetics for ammonium (NH4(+)) oxidation and nitrite (NO2(-)) under the effect of hydroxylamine (NH2OH) were studied by respirometry using nitrifying sludge from a laboratory-scale sequencing batch reactor. Modified models used to estimate parameters ammonia hydroxylamine. An inhibition on was observed different concentration levels. self-inhibition coefficient noncompetitive estimated simulating exogenous oxygen-uptake rate profiles, respectively. inhibitive NH2OH nitrite-oxidizing...
Abstract Surface waters are suffering continuous discharging of pollutions, and low DO black-odorous were easily formed, especially in those slow-flowing urban lakes enclosed small ponds. In-situ treatment by artificial aeration or water cycling with a combination polyurethane sponge as biofilm carriers can disentangle this situation without any land occupation. Long-term experiments (187 days) showed that indigenous microorganisms surface could form biofilms the novel style sponge-based...
