Our company provided submersible mixers, submersible low-speed propellers, aerators and mud scrapers for this project.
The secondary biological treatment process of the high-speed rail sewage plant adopts the multi-mode AAO process. Two groups of pools are symmetrically arranged. Each group of pools is set up with a selection zone, anaerobic zone, anoxic zone and an aerobic zone. It can be adjusted according to the incoming water volume, water quality characteristics and environment. As conditions change, the traditional AAO process, return sludge denitrification AAO process, and inverted AAO process can be flexibly selected, so that it will have an efficient and stable treatment effect when the water volume changes in different seasons and different urban development periods. . The application of this model makes the energy saving and consumption reduction of the high-speed railway new city sewage treatment plant at the leading level among similar sewage plants.
