Study on Substrate Inhibition Kinetics in Anammox-UASB Reactor

摘要

The study on substrate inhibition kinetics in Anammox-UASB reactor was carried out treating low C/N wastewater. Haldane model was researched through non-linear fitting to represent the inhibition caused by nitrite. The results showed that Haldane model was suitable for fitting dynamics model. In Haldane model, r_(max) was 1.15 kg/(m~3?d), K_S=9.31 mg/L, K_(IH)=476 mg/L. On condition that the concentration of nitrite was 66.57 mg/L, substrate conversion rate reached the highest value which was 0.90 kg/(m~3?d) actually. And it was 78.1% of the highest value in theory.
