Ship domestic sewage treatment equipment

Abstract

The invention discloses ship domestic sewage treatment equipment, and belongs to the technical field of ship sewage treatment. The ship domestic sewage treatment equipment comprises a reaction box, the lower end of an output shaft of a motor A penetrates through the interior of a filter screen, extends to the exterior and is sleeved with two stirring rods in an up-down structure, and a sealing ball A is arranged at the upper end of a spring C. The left side of an L-shaped pipeline communicates with a temporary cavity, and a piston is slidably connected in the temporary cavity. A through hole is formed in the middle of the circumferential outer wall of the control column, a sealing ball B is arranged at the right end of a spring D, a square-shaped block is fixedly arranged at the left end of the control column, an output shaft of a motor B is coaxially connected with a Z-shaped rod, and a water outlet pipe is arranged at the left end of the front side of the reaction box. Due to the close fit of the structures, the sewage and the medicament are fully mixed through the stirring of the stirring stick, and the piston and the temporary cavity are arranged, the reaction time of the sewage and the chemical agent is effectively prolonged, and the situation that the reaction is insufficient, so that the sewage which is not sufficiently treated is discharged into the ocean, and serious ecological pollution is caused is avoided.

Description

technical field [0001] The invention relates to the technical field of ship sewage treatment, and more specifically relates to a ship domestic sewage treatment equipment. Background technique [0002] Marine pollution mainly refers to the pollution of the surrounding water environment and atmospheric environment generated by ships during navigation, berthing in ports, loading and unloading cargo, and the life of offshore platform operators. The main pollutants are oily sewage, domestic sewage, and ship garbage. category. The pollutants contained in sewage are mainly organic matter and a large number of pathogenic microorganisms. The organic matter in domestic sewage is extremely unstable and easy to rot and produce stench. Bacteria and pathogens multiply by using organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases Popular, the current filter screen of sewage treatment equipment is usually blocked by some large debris or debris...

The pollutants contained in sewage are mainly organic matter and a large number of pathogenic microorganisms. The organic matter in domestic sewage is extremely unstable and easy to rot and produce stench. Bacteria and pathogens multiply by using organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases Popular, the current filter screen of sewage treatment equipment is usually blocked by some large debris or debris in the sewage that is insoluble in water, and the filter screen is blocked. There are still a lot of organic matter and pathogens remaining

The prior art publication number is CN210215101U, which provides a kind of domestic sewage treatment equipment for ships. The utility model provides four oblique baffles in the anoxic tank, so that the original vertical flow direction of the water flow is transformed into The zigzag flow direction makes the sewage flow rightward and downward to the second slant baffle under the action of the first slant baffle, and after the turning of the second slant baffle, the water flow speed slows down and flows to the left and downward, and then passes through Turning of the thir
