AI Technical Summary
Traditional biological denitrification processes have high oxygen consumption and aeration energy consumption, and there are also conflicts between microbial competition and environmental conditions, resulting in decreased denitrification efficiency, large footprint, low mass transfer efficiency, complex control, high operating costs, and the risk of secondary pollution.
The anaerobic ammonia oxidation zone, short-cut nitrification zone, and settling zone are integrated into one unit. Granular sludge layers and biological packing layers are used in synergy. Multi-layer elastic three-dimensional packing layers and annular aeration pipes are set up to create suitable environmental conditions, improve bacterial activity and denitrification efficiency.
It saves floor space, avoids sludge loss, improves denitrification efficiency, reduces operating costs, enhances mass transfer efficiency, resolves the conflict between microbial community environmental needs, and achieves efficient wastewater treatment.
