1. Shock load resistance, long sludge age, less residual sludge, high efficiency and flexible operation.
2. The sludge concentration in the reactor is high, and the general sludge concentration is 5~10 times that of the ordinary activated sludge method, and the mass concentration of sludge in the aeration tank can be as high as 30~40g/L.
3. The head loss is small, it should not be blocked, there is no need for backwashing, and there is generally no need for backflow.
4. As the core of the MBBR process, the suspension filler has aerobic and anaerobic metabolic activities, and can be used for good denitrification and phosphorus removal.
