英文摘要	A sequencing batch reactor (SBR) was operated more than 200 d to treat nitrogen-rich saline wastewater by anammox process. The temperature was controlled at 35 +/- 0.5 degrees C and the mixed liquor suspended solids (MLSS) was around 4000 mg TSS/L. Anammox reactor could gradually acclimate to 100% seawater. However, the long-term effects of 50% seawater not only affected nitrogen removal performance, resulting in a decrease of nitrogen removal rate (NRR) to 0.114 kg N/(m(3).d), but also weakened sludge settling ability. The effect resulting from 50% seawater was reversible and the NRR gradually increased to 0.419 kg N/(m3.d) by adding sponge carriers. Analysis of variance (ANOVA) test shown that Delta NO3-N/ANElt-N ratio was significantly different (p < 0.05) under different seawater content. After inhibition resulting from 100% seawater, the response process of anammox could be divided into three periods. At 100% seawater, nitrogen removal performance of anammox reactor was affected when influent nitrite was higher than 150 mg NIL (NO2-Nnif/NH4+-N-inf = 1.37 +/- 0.02). Luong model was suitable to analyze inhibitory effect resulting from nitrite under saline surroundings. (C) 2018 Elsevier Ltd. All rights reserved.
