“…5). Furthermore, the saturation concentration of total nitrogen and phosphorus was less than that obtained from previous researchers (Ni et al 2012;Huang et al 2014). This value illustrated that the growth rate of biomass in the bioreactor could be maintained at an appropriate level while the limited substrate was available (Huang et al 2014).…”

The simultaneous biological removal of COD, TN and phosphorus from meat industrial wastewater (MIW) using a lab‐scale high rate up‐flow anaerobic–anoxic–oxic bioreactor (A2O bioreactor) was investigated. The bioreactor was operated at different HRT, COD/TN ratio and aerated volume fractions to monitor the COD and nutrient removal efficiency. The maximum COD removal rate was detected at HRT of 5 h and COD/TN ratio of 100 : 12. The total nitrogen removal efficiency was changed between 65.8 and 94.4% and the lowest effluent nitrate concentration was measured as 1.6 mg/l. Seven kinetic models were applied to experimental data to determine the substrate utilization rate. The Monod and Haldane models were ideal to estimate the reactor performance. Moreover, the cost performance evaluation indicated the A2O bioreactor capability in low energy consumption for MIW treatment. According to the modeling results, integrating anaerobic and aerobic zones within a single bioreactor could be beneficial and cost‐effective due to the high effluent quality and low operational costs.

“…Thus, it could be observed that the modified Stover‐Kincannon model was the most fitting precision model to describe ammonium removal of two‐step aerobic processes than the first‐order removal model and Monod‐BCO model either in O 1 or in O 2 processes. The probable reason is that only substrate loading rate is introduced as a variable without other hard‐to‐measure parameters determined for substrate removal prediction leading to the Stover‐Kincannon model being capable of predicting ammonium removal at different organic loading conditions, no matter how organics affected ammonium removal.…”

A novel four‐stage pilot‐scale anaerobic/anoxic/oxic/oxic (A2/O2) biofilm process was successfully developed to treat coking wastewater with high ammonium loading. In this study, three different dynamical models including the first‐order substrate removal model, the Monod‐biological contact oxidation (Monod‐BCO) model, and the modified Stover‐Kincannon model were particularly applied to analyze kinetics of ammonium removal in a two‐step aerobic stage. For the O1 reactor, all models were appropriate for describing ammonium removal and the correlation coefficients of first‐order substrate removal model, BCO model, and modified Stover‐Kincannon model were 0.8974, 0.9210, and 0.9726, respectively. The model verification indicated that the modified Stover‐Kincannon model was slightly more applicable to predict ammonium removal in the O1 reactor. It was demonstrated that the maximum removal rate of ammonium was 0.208 kg/(m3 · d) by the Stover‐Kincannon model. For the O2 reactor, the modified Stover‐Kincannon model turned out to be the best fitting kinetic model for ammonium removal compared to the first‐order substrate removal model (R2 = 0.1556) and Monod‐BCO model (R2 = 0.5022). The maximum ammonium conversion rate (Um2‐O2) by the modified Stover‐Kincannon model was 1.180 kg/(m3 · d), while saturation rate constant k3‐O2 was 1.221 kg/(m3 · d). Furthermore, the determination coefficient between measured and predicted values obtained by the modified Stover‐Kincannon model was quite high (R2 = 0.9788) in the O2 process and a lower average residual square (6.60 × 10−6) was also obtained. The results of kinetic studies by the Stover‐Kincannon model can predict ammonia removal efficiency well in two‐step aerobic biofilm reactors of a coking wastewater treatment combined system.

BACKGROUND: Anaerobic ammonia oxidation, or anammox, is one of the most efficient techniques to dispose of sewage ammonia nitrogen and nitrite nitrogen within a reactor. Kinetics equations of anammox have been studied under proportions of ammonia nitrogen and nitrite nitrogen in the laboratory, however, in wastewater treatment, the reaction conditions are variable and unstable. RESULTS: Two strains of anammox bacteria, Candidatus Brocadia fulgida and Candidatus Brocadia caroliniensis, were identified by PCR and assigned the formal bacterial serial numbers: KR005667 and KR005668, respectively. The degradation curves of the two anammox bacteria were drawn by calculating the kinetics parameters using the Michaelis-Menten equation, and the ammonia oxidation rates, nitrite conversion rates and Km values of ammonia and nitrite were close to or identical to the known data range of the kinetics of anammox bacteria metabolism.CONCLUSION: A hypothesis regarding the role of extracellular polymeric substance (EPS) was proposed and the reaction mechanism of anammox bacteria was deduced in the case of a disproportionate substrate concentration.
