Abstract

The invention relates to a device for treating ship ballast water with a coal-based carbon film and a method. The device is directly embedded into pipelines of the existing ballast water loading system on the ship, and a ballast water inlet joint connects the device of the invention with the inlet pipelines of the existing ballast water loading system; when the ship loads the ballast water, the ballast water passes through the ballast water inlet pipelines, and enters a film pool after being treated by a pre-treatment device; after the ballast water is treated by the coal-based carbon film, phytoplankton, zooplankton, bacteria and the like in the ballast water are filtered so as to avoid the problem of the invasion of external creatures caused by the transfer of the ballast water in the ship, finally the treated ballast water enters a ballast tank through the ballast water tank inlet pipelines, and the treated concentrated water is discharged through concentrated water outlet pipelines. The concentrated water outlet pipelines and the on-ship ballast water discharging pipelines are connected or directly discharged into the sea. The invention can realize safety, practicability, economy and effectiveness, is environment-friendly, and is easily promoted on the ship on a large scale.

Description

technical field [0001] The invention relates to a device and method for treating ship's ballast water. Background technique [0002] With the development of world trade and economic globalization, ships frequently travel around the world. As an effective medium for the spread of alien species, ship ballast water enables species in different waters to spread to other waters. It is estimated that there are about 12 billion tons of ballast water carried by ships in the world every year, and there are as many as 3,000 species of organisms that travel around the world in the ballast water of ships every day. So far, about 500 species have been confirmed to be caused by Ballast water spread. The invasive spread of these alien species destroys the diversity of marine life, nearshore and coastal ecosystems, threatens the survival of local species, and even endangers the health of local residents. The problem of alien biological invasion caused by ballast water transfer has attract...
