摘要: Abstract Our previous study indicated that a low dissolved oxygen (DO) could enrich and shift nitrifier community, making complete nitrification feasible under long-term DO conditions. This research determined kinetic constants, quantified the chronic effect of on overall process. For ammonia oxidizing bacteria (AOB), half-velocity constants growth ( K DO-g ) decay DO-d were 0.29 0.48 mg L −1 , respectively. nitrite (NOB), those values 0.08 0.69 mg L The for both AOB NOB suggest greater than 1 mg L does not provide further benefit to nitrification, lower value suggests oxidation is less impacted by DO. 0.48 NOB, respectively, significantly inhibits resulting in their enrichment. relationship between operational required SRT was developed theoretical foundation operating an advanced wastewater treatment plant DO, improve aeration energy efficiency.
