The invention discloses a marine sequencing batch aeration sewage treatment system and treatment method. The sewage treatment system comprises a sequencing batch treatment unit and an ultrafiltration membrane treatment unit; the sequencing batch treatment unit comprises a buffer cabinet, a sequencing batch cabinet and a clear water cabinet, and the lower end of the buffer cabinet is communicated with the upper portion of an inner cavity of the sequencing batch cabinet and a discharge outlet through a first pipeline assembly; the sequencing batch cabinet adopts a sequencing batch treatment process to perform sequencing batch biological contact oxidation treatment on sewage, the middle position of the inner cavity of the sequencing batch cabinet is also communicated with the clear water cabinet through a second pipeline assembly, and the lower end of the clear water cabinet is respectively communicated with the ultrafiltration membrane treatment unit and the discharge port through a third pipeline assembly; and the ultrafiltration membrane treatment unit is further communicated with a discharge port through a fourth pipeline assembly, so that produced water obtained after treatment of the ultrafiltration membrane treatment unit is discharged out of a ship through the discharge port. The sewage treatment system has multiple water treatment modes and is small in size, stable in effluent quality and high in biochemical efficiency.
本发明公开了一种船用序批曝气污水处理系统及处理方法,污水处理系统包括序批处理单元和超滤膜处理单元,序批处理单元包括缓冲柜、序批柜和清水柜,缓冲柜下端通过第一管道组件分别与序批柜内腔的上部和排放口连通,序批柜采用序批式处理工艺对污水进行序批式生物接触氧化处理,且序批柜内腔的中部位置还通过第二管道组件与清水柜连通,清水柜的下端通过第三管道组件分别与超滤膜处理单元和排放口连通,超滤膜处理单元还通过第四管道组件与排放口连通,以将经所述超滤膜处理单元处理后得到的产水经所述排放口排放到船外。本发明的污水处理系统具有多种水处理模式,且体积小、出水水质稳定,且生化效率高。
