Problems solved by technology

[0003] The utility model patent of utility model application publication number CN 207203607 U discloses a kind of ship sewage treatment equipment. In this technical solution, the sewage passes through the filter cartridge, and the sediment accumulates at the bottom of the filter cartridge. When the sediment reaches a certain amount, it is time to squeeze out The pressure plate squeezes downwards, and further squeezes the sewage in the sediment, so that the sewage enters the drainage chamber through the filter screen, and the squeezed sediment is drained. At the same time, the downward squeezed sediment will squeeze out the baffle and enter Sewage room, so that the ship can store more sediment and discharge it on land, but this treatment method is limited to the treatment of filtrate, the water treatment is not complete, and the fresh water recycling rate is low

Embodiment 1

[0030] The present invention provides such Figure 1-4 The shown ship sewage treatment device includes a frame 1, a pretreatment cylinder 2 is fixed on the top of the frame 1, a motor 3 is arranged at the center of the top of the pretreatment cylinder 2, and a motor 3 is arranged on one side There is a water inlet pipe 4 and the other side is provided with a dosing hopper 5, the water inlet pipe 4 and the dosing hopper 5 are all connected with the pretreatment cylinder 2, and the end of the output shaft of the motor 2 is fixedly connected with a rotating shaft 6, so The middle part of the circumferential side of the rotating shaft 6 is fixed with a stirring rod 7 and a scraper 8 at the bottom, and a connecting pipe 10 is arranged at the center of the bottom of the pretreatment cylinder 2, and the connecting pipe 10 and the dosing bucket 5 are all provided with There is a control valve, and a hydraulic cylinder 14 is arranged on one side of the connecting pipe 10, and the hydra...

Embodiment 2

[0039] A ship sewage treatment method, including the ship sewage treatment device, also includes the following steps:

[0040] S1: connect the sewage treatment device with an external power supply;

[0041] S2: Then pass the sewage into the pretreatment cylinder 2 from the water inlet pipe 4;

[0042] S3: Open the control valve on the dosing hopper 5, so that the medicine in the dosing hopper 5 enters the pretreatment cylinder 2, and at the same time, start the motor 3 to work through the external controller to drive the rotating shaft to rotate, thereby using the stirring rod 7 and The scraper 8 stirs the sewage in the pretreatment cylinder 2;

[0043] S4: The curved surface 9 has a tapered structure design from the outside of the scraper 8 to the center, and its end surface is set as a spherical surface to scrape off the remaining flocs on the inner wall of the pretreatment cylinder 2;

[0044] S5: Open the control valve on the connecting pipe 10, so that the sewage mixed ...

Abstract

The invention discloses a ship sewage treatment device and method. The device comprises a frame, a pretreatment cylinder is fixedly arranged at the top of the frame, a motor is arranged at a top center position of the pretreatment cylinder, a water inlet pipe is arranged at one side of the motor, and a drug adding hopper is arranged at the other side of the motor. The water inlet pipe and the drugadding hopper both communicate with the pretreatment cylinder, the output shaft end of the motor is fixedly connected with a rotating shaft, and the middle part of the circumferential side of the rotating shaft is fixedly provided with agitating rods, and the bottom of the rotating shaft is provided with scrapers. A center portion of the bottom of the pretreatment cylinder is provided with a connecting pipe. The device of invention adds a drug into the pretreatment cylinder by using the drug adding hopper, and uses the motor to drive the stirring rods and the scrapers to agitate sewage with the added drug so as to precipitate some harmful substances in the sewage, then enables the sewage to be introduced into a pressure filter cylinder for pressure filtration, and at the same time, uses awater treatment mechanism to purify the filtered sewage to meet a drinking standard.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a ship sewage treatment device and method. Background technique [0002] Marine sewage treatment equipment is an auxiliary equipment for ships. The equipment undertakes the treatment of domestic sewage on board the ship to make it meet the discharge standard. [0003] The utility model patent of utility model application publication number CN 207203607 U discloses a kind of ship sewage treatment equipment. In this technical solution, the sewage passes through the filter cartridge, and the sediment accumulates at the bottom of the filter cartridge. When the sediment reaches a certain amount, it is time to squeeze out The pressure plate squeezes downwards, and further squeezes the sewage in the sediment, so that the sewage enters the drainage chamber through the filter screen, and the squeezed sediment is drained. At the same time, the downward squeezed sediment will squee...
