| Abstract | AbstractTo enhance the removal effect of nitrogen from municipal wastewater and to reduce the operating energy consumption of an oxidation ditch, a modified carrousel oxidation ditch, which established the selection zone, the anaerobic zone, and the anoxic zone, was chosen for study. In addition, the nitrification rate, denitrification rate, and effluent quality were chosen as feasibility criteria, and the operating conditions of intermittent aeration were optimized in a pilot-scale experiment and studied during productive debugging. The results showed that intermittent aeration can enhance the nitrogen removal effect and reduce energy consumption. The characteristic feature of the internal reflux of the modified carrousel oxidation ditch without power consumption was fully utilized, the flow rate in the main reaction zone became large, and the internal reflux flow was increased by enlarging the opening of the internal reflux valve appropriately during the aeration stage. In addition, the pre-anoxic zone ... |
