What is the SBR method? How is the operation process?

Intermittent aeration type activated sludge method, also known as sequential batch activated sludge method, the English is Se-Quencing Batch Reactor, so referred to as SBR method. Its main feature is that the reactor batch by batch to treat sewage, the use of intermittent operation, each reactor both aeration tank and the role of the second sedimentation tank, so no longer set up the second sedimentation tank and sludge reflux equipment, and generally can not build the water quality or water quality adjustment tanks.SBR method generally consists of a number of reactor, sewage according to the sequence of the sequence of entry into each reactor. Whether in time or space, the biochemical reaction process is arranged in sequence, intermittent operation. Intermittent aeration type activated sludge method aeration tank operation cycle by the water intake, aeration reaction, sedimentation, discharge, idle standby five processes, and these five processes are aeration tank.
