•SPNA system combined a novel ICCOMBR for reject water treatment was developed.•SPNA system could maintained stable operation under FA < 5.75 mg/L and FNA < 4 μg/L.•Nitrogen removal efficiency of SPNA system was 82%, with a NLR of 0.6 gN/L/d.•NO2−/NH4+ ratio of 1.15 in PN was achieved by reducing AR from 1.65 to 0.8 L/min.•Anammox abundance in biofilm (22.2%) was equal to that in suspended sludge (20.77%).
A novel internal circulation contact oxidation membrane bioreactor (ICCOMBR) was constructed to investigate a three steps startup strategy of single-stage partial nitritation-anammox (SPNA) system. A stable nitrite accumulation rate (NAR) of 86.60% was achieved with NH4+-N over 250 mg/L in nitritation process. The partial nitritation process could be effectively achieved by reducing the aeration rate (AR) by about 50% in the nitritation process, with an effluent NO2−-N/NH4+-N ratio of 1.15 ± 0.04. The SPNA system was started up in 27 days following the inoculated anammox granular sludge. A total nitrogen removal efficiencies of 82% was achieved at a NLR of 0.60 gN/L/d and dissolved oxygen (DO) concentration below 0.55 mg/L. Anammox function genus (Ca.Kuenenia and Ca. Anammoximicrobium) abundance accounted for 20.77% in the biofilm, which is approximately equal to 22.2% in the suspended sludge. Nitrosomon as the dominant AOB genera, was detected in the biofilm (6.5%) and suspended sludge (13.3%).</description><identifier>ISSN: 0960-8524</identifier><identifier>EISSN: 1873-2976</identifier><identifier>DOI: 10.1016/j.biortech.2020.124432</identifier><identifier>PMID: 33260065</identifier><language>eng</language><publisher>England: Elsevier Ltd</publisher><subject>aeration ; Ammonium Compounds ; anaerobic ammonium oxidation ; biofilm ; Biofilm carriers ; Bioreactors ; dissolved oxygen ; membrane bioreactors ; Microbial community ; Nitrites ; Nitrogen ; oxidation ; Oxidation-Reduction ; Partial nitritation ; Reject water ; Sewage ; Single-stage partial nitritation-anammox ; sludge ; total nitrogen ; Water Purification ; water treatment</subject><ispartof>Bioresource technology, 2021-02, Vol.321, p.124432-124432, Article 124432</ispartof><rights>2020 Elsevier Ltd</rights><rights>Copyright © 2020 Elsevier Ltd.
