Example Embodiment

[0011]The present invention will be further explained below in conjunction with the drawings.

[0012]The mobile ballast water treatment system for ports is mainly suitable for ships calling at the port. It mainly solves the problem of ballast water treatment for ships calling at the port. Through the modular ballast water treatment system, the system is placed in a standard container, which is convenient for port Move to meet the ballast water treatment needs of ships calling at the port, simple and safe!

[0013]Arrange a booster pump at the inlet of the system to ensure the normal pressure of the system operation, and avoid the pressure loss of the ballast pump input due to the longer delivery pipeline and the pressure loss or less pressure. The water flowing from the booster pump enters the high-precision automatic backwash filter, and the filtered water flows into the secondary sterilization unit. The secondary sterilization unit combines "low pressure ultraviolet sterilization + pho...

Abstract

The invention provides a mobile ballast water treatment system for a port. The mobile ballast water treatment system can receive, treat and discharge ballast water which does not reach the standard ofa ship, and provide ballast water meeting authentication requirements for the ship at the same time. The ballast water treatment system is integrated in a skid and placed in a standard container. Themobile ballast water treatment system is convenient to move according to the position of the ship and meets the requirement of the port for a ballast water treatment system. A booster pump is arranged at a system inlet to ensure the pressure required by normal operation of the system; a secondary sterilization unit is combined with low-pressure ultraviolet sterilization, photocatalytic oxidationsterilization and ultrasonic sterilization, so that the sterilization effect is guaranteed; a high-precision filter and a separation device are arranged at a backwashing opening of a self-cleaning filter, backwashing water is avoided, an independent sewage draining opening does not need to be formed in the system, and port pipeline connection work is reduced.

Description

technical field [0001] The invention relates to a port mobile ballast water treatment system, which can be used to receive and treat ship ballast water, and can also provide ballast water meeting certification requirements to fill ballast water tanks. Background technique [0002] Species invasion caused by ships' ballast water poses a great threat to the global marine ecological environment. Come into force, requiring all ships to install ballast water treatment systems. [0003] But there are still some ships that face port delays due to substandard ballast water, and due to objective factors, some ships are not allowed to install ballast water treatment systems. At the same time, for some large ships, such as VLCC / VLOC, the amount of ballast water is huge, and the annual voyage frequency is very small, so it is expensive to install, use and maintain the ballast water treatment system. From a technical and economic point of view, port solutions are urgently needed. Con...
