The beneficial effects of the utility model are as follows: firstly, solid-liquid separation is adopted to separate the solid matter, and then the sewage is homogenized through the treatment of the regulating tank and the contact oxidation tank, and at the same time, the high-concentration activated sludge in the MBR membrane treatment tank is periodically returned to the In the regulating tank, the air provided by the blower stirs the regulating tank, the contact oxidation tank and the MBR membrane treatment tank, so that the organic suspended solids and macromolecular substances in the sewage are fully decomposed, and the sludge volume is reduced.

Description of drawings

Accompanying drawing 1 is the device flowchart of the embodiment of the present utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a ship sewage integrated device includes a solid-liquid separator 1, a regulating tank 2, a contact oxidation tank 5, an MBR membrane treatment tank 8, a reservoir 12 and several connecting pipes, the solid-liquid separator 1 Located in the adjustment tank 2, the adjustment tank 2, the contact oxidation tank 5, the MBR membrane treatment tank 8 and the water storage tank 12 are connected successively by connecting pipes, and also includes a blower 11, which is connected to the adjustment tank 2 through the first ventilation pipe 10 connected, the first ventilation pipeline 10 bypasses the second ventilation pipeline 6 and the third ventilation pipeline 9, and the second ventilation pipeline 6 and the third ventilation pipeline 9 are connected with the contact oxidation tank 5 and the MBR membrane treatment tank 8 respectively ; The MBR membrane treatment tank 8 is connected to the regulating tank 2 through the return pipeline 7 .

The regulating tank 2 is provided with a liquid level gauge 3 and a lifting pump 4 .

The water storage tank 12 is connected with an outflow pump 13 .

First, the solid-liquid separation of the sewage is carried out through the solid-liquid separator. The separated solid matter is manually processed to remove the waste residue. At the same time, the sewage enters the regulating tank for treatment, and the sewage is homogeneous. The lift pump sends the sewage from the adjustment tank to the contact oxidation tank. Under the action of filler microorganisms, the organic matter in the sewage is decomposed and utilized by the microorganisms, and the effluent enters the MBR membrane treatment tank, where the mud and water are separated under the action of the microfiltration membrane. At the same time, the high-concentration activated sludge in the MBR membrane treatment tank is regularly returned to the regulating tank, and the air provided by the blower is used to stir the regulating tank, contact oxidation tank and MBR membrane treatment tank to decompose the organic suspended solids and macromolecular substances in the sewage. Fully realize sludge reduction. The MBR effluent is treated by the ultraviolet sterilizing system and then discharged into the reservoir. Under the action of the effluent pump, the sewage that meets the standard is discharged out of the hull. the
