[0002] Ship's ballast water refers to the water that is sucked from the ocean and added to the ship to control the ship's heel, pitch, draft, stability or stress. Ship's ballast water contains a large number of organisms such as plankton, microorganisms, bacteria, etc. Some of these organisms can survive during the ship's voyage and eventually be discharged into a new environment with the ship's ballast water, affecting the ecological balance of the new water environment. In order to reduce the impact on water and environmental safety caused by the discharge of ballast water from ships, the ship's ballast water needs to be treated.
