Enhanced nitrogen and carbon removal performance of simultaneous ANAMMOX and denitrification (SAD) process with trehalose addition treating saline wastewater was investigated in a sequencing batch reactor (SBR). The optimal nitrogen removal was achieved at 0.25 mmol·L trehalose, during which NH-N, NO-N, NO-N, and COD could be completely removed. Compared to no addition of trehalose, ammonium removal efficiency (ARE), nitrite removal efficiency (NRE) and total nitrogen removal efficiency (TNRE) increased by 50%, 43% and 46%. Ammonium removal rate (ARR) and nitrite removal rate (NRR) increased by 81.25% and 75%, respectively. With increasing concentration of trehalose to 0.5 mmol·L, ARE was only 58.82% and the effluent concentration of NH-N was 33.25 mg·L. Compared to the Haldane model and the Aiba model, the Luong model was the most suitable to simulate the nitrogen removal performance of SAD with trehalose addition treating saline wastewater. The NRR, , , and fitted from Luong model were 0.954 kg·(m·d), 0 mg·L, 184.785 mg·L, and 0.718, respectively. Compared to the modified Logistic model and the modified Boltzman model, the modified Gompertz model was the most suitable to describe the degradation of a substrate in a single cycle.
在序批式反应器（SBR）中研究了添加海藻糖的同时厌氧氨氧化与反硝化（SAD）工艺处理含盐废水时提高的氮和碳去除性能。在0.25 mmol·L海藻糖时实现了最佳的氮去除，在此期间NH-N、NO-N、NO-N和COD可被完全去除。与不添加海藻糖相比，氨去除效率（ARE）、亚硝酸盐去除效率（NRE）和总氮去除效率（TNRE）分别提高了50%、43%和46%。氨去除率（ARR）和亚硝酸盐去除率（NRR）分别提高了81.25%和75%。随着海藻糖浓度增加到0.5 mmol·L，ARE仅为58.82%，NH-N的出水浓度为33.25 mg·L。与Haldane模型和Aiba模型相比，Luong模型最适合模拟添加海藻糖的SAD工艺处理含盐废水的氮去除性能。由Luong模型拟合得到的NRR、 、 和 分别为0.954 kg·(m·d)、0 mg·L、184.785 mg·L和0.718。与修正的Logistic模型和修正的Boltzman模型相比，修正的Gompertz模型最适合描述单个周期内底物的降解情况。
