[0023] Compared with the prior art, the present application has the following advantages:

[0024] 1. The present application breaks through the traditional ballast water treatment process. When the water is in and out, the ballast water is inducted by cooperating with the hypochlorite sensor, and the ballast water is treated by adding oxidizing agent and reducing agent, so that the ballast water is sterilized and algae is treated. The whole operation is simple, the equipment cost is low, the maintenance difficulty is low, the service life is high, and the traditional electrolysis, ultraviolet and ultrasonic means greatly increase the treatment difficulty, the service life is low, and the overall operation and maintenance cost is increased.

[0025] 2. This invention utilizes a mixing pump to transport and mix oxidants and reductants. By arranging delivery holes on the delivery pipe, multi-zone delivery can be achieved within the ballast water transport channel, increasing the contact area between the oxidants and reductants and the ballast water. This allows for timely treatment of the ballast water during flow. Furthermore, the delivery pipe can oscillate back and forth within the ballast water channel. Combined with the rotation of the delivery pipe, this improves processing efficiency. When adapting to different ballast water channel specifications, in addition to adjusting the length of the delivery pipe, the oscillation amplitude can also be adjusted simultaneously. Even when applied to different scenarios, it still ensures sufficient contact between the oxidants and reductants and the flowing ballast water, preventing any omissions in sterilization and algae removal. Furthermore, the diameter of the delivery holes on the delivery pipe varies from bottom to top, allowing the lower delivery holes to provide greater pressure during oscillation, enabling the oxidants and reductants to be thrown further. Combined with the oscillation, this achieves both lateral and longitudinal delivery operations, increasing distribution uniformity. Sterilization and algae removal of ballast water can be achieved with simple operation. Attached Figure Description
