Abstract

The invention discloses a ship ballast water treatment system, which relates to the technical field of water treatment system. The ship ballast water treatment system comprises a ballast pump, a filter and a ballast tank, wherein the ballast pump includes a water inlet and a water outlet, the water inlet of the ballast pump is connected with seawater through a first solenoid valve, the water inlet of the ballast pump is connected with the ballast tank through a second solenoid valve, the water outlet of ballast pump is connected with the ballast tank through the filter, an ultraviolet sterilizer is also arranged on the pipeline between the water outlet of the ballast pump and the ballast tank, the pipeline between the ultraviolet sterilizer and the ballast tank is connected with a water outlet pipe leading to seawater, the outlet pipe is provided with a third electromagnetic valve, and the pipeline between the ultraviolet sterilizer and the ballast tank is provided with a fourth electromagnetic valve. When the third electromagnetic valve is closed and the fourth electromagnetic valve is opened, the seawater flows into the ballast tank after passing through the ultraviolet sterilizer. The invention combines a filter and an ultraviolet sterilizer and can treat the seawater completely.

Description

technical field [0001] The invention belongs to the technical field of water treatment systems, in particular to a ship ballast water treatment system. Background technique [0002] When the ship is sailing, the ship's ballast tank needs to be loaded with a certain amount of ballast water in order to increase the ship's ability to resist wind and waves and improve safety. When the ship is empty, it is necessary to drive the seawater outboard into the ballast tank through the sea bottom valve and centrifugal pump to maintain the stability of the ship during the voyage. When the ship is loaded, it is necessary to discharge part of the ballast water in the ballast tank to the overboard. The untreated ballast water discharged overboard may carry more pollutants such as bacteria, microorganisms and other aquatic organisms, which has brought huge ecological damage to the target sea area and endangered marine life and human health. [0003] The treatment of ship ballast water gen...
