Membrane bioreactor is a high-efficiency sewage treatment technology that combines membrane separation technology and traditional sludge process. With the filtration effect, the organisms are completely trapped in the bioreactor, which realizes the complete separation of water and sludge , and maintains a high MLSS in the bioreactor. Strong nitrification ability and high pollutant removal rate.
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.
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.
5. The anoxic circulating filter bed + moving bed biofilm process has a high process load and a small footprint; it has a wide range of applications and great operational flexibility; it has high processing efficiency and is impact-resistant. The high microbial concentration and attached growth mode with strong impact resistance can effectively disperse the incoming water quality. Fluctuations, stable water output, and impact resistance are significantly higher than traditional activated sludge processes; it has strong tolerance to incoming water temperature, pH fluctuations and toxic substances.
The tank body is made of HDPE (high-density polyethylene) material. The company independently develops production equipment and molds. The product body and accessories are standardized and designed with beautiful design, stable quality and short batch delivery cycle. HDPE material has good structural strength and corrosion resistance, and its service life can reach more than 30 years. At the same time, as an environmentally friendly material, HDPE's production and use processes are environmentally friendly and can be recycled twice.
6. The operation is self-balancing, and there is no need to manually control the sludge load and sludge concentration; due to the existence of solid suspended fillers, the process will not cause sludge expansion and sludge loss problems common in activated sludge processes; the lifespan of the main filler and aeration system It lasts for 10-20 years and is completely maintenance-free; it produces little mud and has a mud discharge cycle of 6-12 months; online remote monitoring and operation can be realized through the APP.
7. The sewage enters the tank through collection. In an anoxic environment, the biofilm on the filler is used to degrade organic matter and remove large particulate matter and suspended solids to improve the biodegradability of the sewage. After that, the sewage enters the aerobic tank and is aerated Under certain conditions, the biofilm on the suspended filler is used to further treat the sewage. The bottom nitrification liquid is flown back to the front-end anoxic tank for denitrification and denitrification treatment, and electrolysis of phosphorus is performed at the same time. The treated water enters the biological filtration tank for sedimentation filtration to remove The suspended matter in the sewage finally enters the disinfection tank, where it is disinfected by chlorine tablets to complete the final treatment of the sewage.
