Mobile ballast water treatment system for port

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...
