Description

Technical Field

[0001] The present invention relates to the technical field of shipboard sewage treatment, and in particular to a shipboard intelligent sewage treatment device and a water circulation regeneration system. Background Art

[0002] Due to the limited space inside the ship, the site for installing sewage treatment equipment is relatively small, which requires the sewage treatment device to be compact and small in size. And because the ship may be far away from the land for a long time during navigation, the sewage treatment system must be able to operate independently and stably, with strong reliability and self-maintenance capabilities. The sewage on the ship comes from various sources, including domestic sewage, kitchen waste water, bilge water, etc., and the water quality and water volume fluctuate greatly, which also places high demands on the adaptability of the treatment system. In addition, ships will face various climate and sea conditions during navigation, which may affect the operating stability and safety of sewage treatment equipment.

[0003] The sedimentation tank in the ship's water recycling system is mainly used to precipitate solid particles with a larger specific gravity in the sewage and separate them from the liquid, thereby removing suspended matter and some colloidal substances in the sewage. In order to ensure the sedimentation effect of the sedimentation tank, if the sewage discharge device at the bottom of the tank body continues to work, it will increase the flow of sewage in the tank body, which is not conducive to the precipitation of solid particles. Therefore, when the sewage discharge device is not working, a large amount of solid particles and colloidal substances solidify at the bottom of the sedimentation tank, which is easy to form a relatively solid and immovable dirt block. The existing sewage discharge assembly at the bottom of the sedimentation tank is easy to be difficult to start, which affects the stability and reliability of the ship's water circulation system.
