Abstract

The invention relates to a treatment system for ship effluent discharged by a ship. The treatment system is characterized by comprising an effluent collecting tank, a pretreatment tank, a sludge tank, an oil and water separator, a waste oil recovering barrel, a membrane bioreactor, an effluent monitoring device, an evaporation and concentration tank and a liquid storage tank. The effluent discharged by the ship is treated in a series of steps to obtain recyclable fresh water, sustainable utilization of resources is effectively achieved, the discharge amount of the effluent to a water body is reduced, and the degree of hazards to the environment by the effluent discharged by the ship is greatly relieved.

Description

technical field [0001] The invention relates to the technical field of ship waste liquid treatment, in particular to a treatment system for ship waste liquid discharge. Background technique [0002] Ship sewage treatment and discharge are usually carried out in accordance with the international pollution prevention convention. With the enhancement of environmental protection awareness, the international pollution prevention convention has been continuously revised. The design and treatment effect of sewage treatment systems are facing new challenges. [0003] Ship waste mainly comes from ship domestic sewage, ship oily wastewater and ship ballast water. Ship domestic sewage comes from the daily drainage of people on board, and the drainage can be divided into two types: black water and gray water according to the water quality. Black water refers to toilet flushing drainage with high pollutant content, that is, fecal sewage; gray water refers to less polluted wastewater fr...
