Ballast water treatment method and system based on biological detection

Abstract

The invention provides a ballast water treatment method and system based on biological detection, and the method comprises the steps: carrying out the real-time sampling of ballast water when a ship carries out the pumping operation of the ballast water, so as to obtain a real-time water sample of the ballast water, and obtaining the real-time pumping information corresponding to the pumping operation; performing real-time biological detection on the real-time water sample; based on the real-time pumping information and historical data of the ship, whether the real-time biological detection result is abnormal or not is determined; and if the ballast water is abnormal, determining a target disinfection mode based on the real-time biological detection result, and disinfecting the ballast water according to the target disinfection mode. By adopting the system and the method, a proper disinfection mode can be automatically selected to disinfect the ballast water in combination with the real-time biological detection result and the real-time pumping information of the ballast water and historical data of the ship, so that harmful species are prevented from being spread across regions through the ballast water, the labor cost required by ballast water treatment is reduced, the disinfection efficiency of the ballast water is improved, and the working efficiency of the ship is improved. Therefore, the real-time performance of ballast water treatment is ensured.
