Background
SBR is an abbreviation of sequencing batch intermittent activated sludge process, and is a new technology for biological sewage treatment which has been paid attention to, studied and widely popularized and applied at home and abroad in recent years. The operation process is divided into five stages of water inlet, aeration, precipitation, water discharge and idle. Its advantage is simple process. The regulating tank has small volume or no arrangement, no secondary sedimentation tank and sludge reflux, compact structure, small occupied area, low operation cost and the like.
Referring to a pipeline back flushing device of an SBR sewage treatment system (publication number: CN206359320U is 2017-07-28), the two ends of a back flushing pipeline with scale easy to accumulate are connected with a back flushing tank and a waste water tank, when flushing is needed, valves at the two ends of the back flushing pipeline are closed to enable the valves to be independent, water is fed from the output end of the back flushing pipeline, water is discharged from the input end of the back flushing pipeline, and the flushed waste water and scale flow into the waste water tank to realize flushing action; after the flushing is finished, valves among the backwashing tank, the wastewater tank and the backwashing pipes are closed, valves at two ends of the backwashing pipes are opened, and sewage water treatment is continued. The technical scheme avoids the complicated step that the pipeline is required to be disassembled for cleaning the scale by the traditional method, saves time and cost, and is simple and easy to implement.
