AAO Process Integrated WWTP
Product Description
The integrated sewage treatment plant can effectively remove BOD5, COD and NH3-N. It has the characteristics of stable and reliable technical performance, good treatment effect, low investment, automatic operation, and convenient maintenance and operation. At the same time, MBR, MBBR, AO, AAO and other processes can be provided.
Working Principle：
Replacing the end secondary sedimentation tank of traditional biological treatment technology with membrane modules, maintaining a high concentration of activated sludge in the bioreactor, increasing the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities, and reducing residual sewage by maintaining low sludge load amount of mud. It mainly uses activated sludge and macromolecular organic matter in the retention tank of the membrane separation equipment immersed in the aerobic biological tank. The concentration of activated sludge in the membrane bioreactor system can be increased to 8000~10,000mg/L, or even higher; the sludge age (SRT) can be extended to more than 30 days.
Advantages：
1. A/O biological contact oxidation process is used as the main process, elastic three-dimensional fillers are set in the A-level pool, and three-dimensional columnar elastic fillers are set in the O-level pool, with large specific surface area and high microbial activity, which can quickly remove organic pollutants and have a good denitrification effect. .The specific surface area of the filler is 16-20 times that of the ordinary solid filler, which shortens the biochemical time and greatly reduces the floor space.
2. The equipment can be buried underground: basically does not occupy the surface area, does not need to build a house, heat preservation, and the surface can be greened for driving.
3. Easy to manage and maintain.
4. Small impact on the surrounding environment.
