Journal ArticleDOI
Shortcut nitrification–denitrification by real-time control strategies
TL;DR: The study showed that real-time control strategy could prevent excess aeration and achieve stable shortcut nitrification-denitrification and nitrosation ratio (NO(2)-N/NO(x)(-)-N) higher than 96%.
Journal ArticleDOI
Optimization denitrifying phosphorus removal at different hydraulic retention times in a novel anaerobic anoxic oxic-biological contact oxidation process
TL;DR: In this article, a modified two-sludge system consisting of AAO and BCO (Anaerobic anoxic oxic-biological contact oxidation) was developed, which achieved the simultaneous removal of both nitrogen and phosphorus.
Journal ArticleDOI
Enhanced nutrient removal in three types of step feeding process from municipal wastewater.
Yongzhen Peng,Shijian Ge +1 more
TL;DR: Enhanced nitrogen and phosphorus removal and optimized organics utilization were obtained simultaneously in the modified UCT type with both internal and sludge recycle ratios of 75% as well as anaerobic/anoxic/oxic volume ratio of 1:3:6.
Journal ArticleDOI
Improving nutrient removal of the AAO process by an influent bypass flow by denitrifying phosphorus removal
TL;DR: In this article, the possibility of influent carbon source usage by influent bypass flow strategy in the anaerobic-anoxic-oxic (AAO) process was investigated, aiming at enhancing biological nitrogen removal based on enriched denitrifying phosphate accumulating organisms (DNPAOs).
Journal ArticleDOI
Improvement of nutrient removal by optimizing the volume ratio of anoxic to aerobic zone in AAO-BAF system.
TL;DR: The AAO-BAF system could achieve efficient nitrogen and phosphorous removal with limited carbon source, and the average removal efficiencies of COD, TN and PO4(3-) were 89±4, 83±3% and 99±1%, respectively.
