Sequencing Batch Reactor (SBR) is used for effective treatment of kitchen sewage. The flow chart of treatment process of kitchen sewage for water reuse is determined and then, the treatment device and system of kitchen sewage for water reuse is designed and established. It is shown that around 95%, 98%, and 90% of CODcr, BOD5, and SS can be removed respectively through experiments, the quality of effluent can meet the National Water Reuse Standard, and the treated effect is outstanding and stable. So the flow chart of treatment process can be extended further to sewage treatment for water reuse in modern residential quarters and public buildings.
