Embodiment 1

[0038] Such as figure 1 As shown, the present invention provides a marine sewage treatment system, which includes an oil-water separator 1, a precision filter 2, a resin adsorption system 3, an MBR membrane bioreactor 5, a liquid buffer tank 6, a membrane separation device 7 and ultraviolet sterilizing device 8; the oil-water separator 1, precision filter 2, resin adsorption system 3, MBR membrane bioreactor 5, liquid buffer tank 6, membrane separator 7 and ultraviolet sterilizing device 8 are all provided with inlets and export;

[0039] The outlet of the oil-water separator 1 is connected with the inlet of the precision filter 2, the outlet of the precision filter 2 is connected with the inlet of the resin adsorption system 3, and the outlet of the resin adsorption system 3 is connected with the MBR membrane bioreactor 5, the outlet of the MBR membrane bioreactor 5 is connected with the inlet of the liquid buffer tank 6, and the outlet of the liquid buffer tank 6 is connect...

Embodiment 2

[0058] The difference between embodiment 2 and embodiment 1 is:

[0059] The residence time of sewage in precision filter 2 is 50min. The saturated adsorption volume of the resin in the resin adsorption system 3 is 80 times the volume of the resin.

Embodiment 3

[0061] The difference between embodiment 3 and embodiment 1 is:

[0062] The residence time of sewage in precision filter 2 is 120min. The saturated adsorption volume of the resin in the resin adsorption system 3 is 120 times the volume of the resin.

Abstract

The invention discloses a swage disposal system for a ship and a disposal method of the swage disposal system. The sewage disposal system for the ship comprises an oil water separator, a precise filter, an ultraviolet sterilizing device, a resin adsorption system, an MBR membrane bioreactor, a liquid buffer tank and a membrane separator. The disposal method for the swage disposal system for the ship comprises the following steps: (1) sewage flows into the oil water separator; (2) the sewage enters the precise filter from the oil water separator to be filtered; (3) water flowing out of the precise filter enters the ultraviolet sterilizing device; (4) water flowing out of the ultraviolet sterilizing device enters the MBR membrane bioreactor; (5) water flowing out of the MBR membrane bioreactor enters the liquid buffer tank; (6) water flowing out of the liquid buffer tank flows to the membrane separator; (7) water flowing out of the membrane separator enters the resin adsorption system. The sewage disposal system is simple in structure and good in purifying effect.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a marine sewage treatment system and a treatment method thereof. Background technique [0002] With the unprecedented development of the shipping industry and ocean development, the environmental pollution of the ocean is becoming more and more serious, and human beings are paying more and more attention to the protection of the ocean. The problem of ship domestic sewage pollution brought by the ocean has also aroused great concern of human beings. Ship domestic sewage contains a large number of bacteria, parasites and even viruses and high concentrations of eutrophication substances. These untreated domestic sewage is discharged into the water environment without treatment, which will infect aquatic organisms and humans, endangering organisms and human health In addition, after the nutrient salt enters the water environment, when its content reaches 0.01mg / L, it can cause excess...
