Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

The marine aeration device is a part of a marine domestic sewage device and is used for supplying oxygen to an aeration cabinet of the marine domestic sewage device.

Current marine domestic sewage device generally includes collection cabinet, sediment cabinet, anaerobism cabinet, aeration cabinet and the filtration cabinet that communicates in proper order, and the exit end of filtering the cabinet is connected and is discharged the pipeline, installs the delivery pump on this delivery pipeline, and this delivery pump is used for discharging the sewage up to standard after the filtration cabinet. The conventional marine domestic sewage device further comprises an electric cabinet to control treatment of sewage on a ship through the electric cabinet, wherein the electric cabinet in the marine domestic sewage device is a conventional well-known electric cabinet, such as an electric cabinet used in a marine domestic sewage treatment device with the model of WCBJ227M-10, and an electric cabinet used in a marine domestic sewage device with the model of WCHYL-P/2 which is produced by an electric company for stand alone in Wuhan Zhongshan.
