3, SBR Wastewater Treatment Process Description sequencing batch activated sludge process for short SBR (Sequence Batch Reactor) method, the early filling and emptying of an improved reactor. With the automation level of Diti Gao, SBR method to re-arouse the people s attention, and he carried out a more Shenru research and improvement, China s first seat since 1985 SBR processing equipment in the production, now has been widely used in Gongyewushui He Urban Wastewater Treatment .
The basic operation of SBR process flow from the water, reaction, sedimentation, water and idle composition of five basic processes, from the end of the sewage flow to form a cycle idle in each cycle is the process of aeration or in a set reactor mixing device in turn to.

SBR technology system composed of simple (Figure 2), no secondary sedimentation tank, aeration tank combines the functions of the secondary settling tank, no sludge return device. SBR with high efficiency, good effect dehydrogenation of phosphorus to prevent sludge bulking properties of strong resistance to shock loading and processing ability and so on.
4, AC500 control in the concrete realization of SBR SBR sewage treatment plant control system formed by the three distributed control system (Figure 3).
