What is a SBR?
The main characteristic of it is on the run orderly and intermittent operation, the SBR technology is the core of the SBR reaction pool, the pool early homogenization, heavy, biodegradation, secondary mat and other functions in a pool, no return sludge system.
It is especially suitable for occasions where intermittent discharge and flow change are large.
At present, there is a wide application in China.
In most cases (including industrial wastewater treatment), there is no need to set up the regulating pool;
SVI value is low, sludge is easy to precipitate, in general, does not produce sludge expansion phenomenon;
The removal of nitrogen and phosphorus removal in a single aeration tank by adjusting the operation mode;
The application of automatic control instruments such as electric valve, liquid level meter, automatic timer and programmable controller can make the process of this process be fully automated and controlled by the central control room.
Proper operation and management, the treatment of water quality is better than continuous;
When the depth of the pool is deepened, the floor area is relatively small compared with other methods of the same bod-ss load.
Resistant to shock load, high ability to dispose of toxic or high concentration organic wastewater.
Background: in recent years the sequencing batch activated sludge process (SBR) pig farm wastewater treatment more and more attention, this process compared to other process is simple, less surplus sludge disposal problem and saving province, covers an area of less investment, low operation cost, resistance to toxic organic load and impact load, flexible operation mode, because it is static precipitation, therefore, the application of anaerobic-aerobic water effect is good (short) alternating oxygen anaerobic-aerobic process, sludge age is short, high activity, good DE nitrification and phosphorus removal effect.
In addition, there are reports of real-time control of SBR reaction process through REDOX potential, which further increases the removal efficiency of nitrogen and phosphorus, and saves energy and investment.
