Description

technical field [0001] The invention relates to a ship ballast water treatment device, in particular to a device for effectively treating ship ballast water through a dielectric barrier discharge reaction device. Background technique [0002] In order to maintain a certain draft and prevent capsizing when the ship is empty, a certain amount of seawater is pumped into the bilge to enhance the ability to resist wind and waves when it sets sail, and the water is released when it is loaded. This part of the sea is called a ship. ballast water. [0003] Ballast water is an important measure to ensure the safety of ship navigation, but it inevitably carries a large number of microorganisms during its injection and discharge. The marine organisms carried in the ship's ballast water are mainly those species that are very small and can enter the ship's ballast water suction inlet and ballast water pump, mainly including: bacteria, viruses, algae, protists, molluscs and fish.

Problems solved by technology

Although there have been some studies on the application of dielectric barrier discharge technology to water treatment, the traditional method of dielectric barrier discharge plasma treatment of wastewater is to generate dielectric barrier discharge in the gas, and the generated plasma gas is passed into the water through the mass transfer process for sewage treatment. There are problems such as low mass transfer efficiency, ineffective mass transfer of short-lived substances, high cost, and inability to process continuously, and it has not been applied on ships
