Embodiment Construction

[0039] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0040] The invention provides a high-efficiency ship ballast water treatment system, such as figure 1 As shown, the system includes seawater suction pump, seawater discharge pump, cyclone separator, UV sterilizer and ballast water tank.

[0041] The seawater suction pump sucks seawater from the sea area, and the seawater discharge pump sucks ballast water from the ballast water tank.

[0042] The cyclone separator uses the centrifugal force generated by high-speed rotation to separate impurities from the seawater, so that all marine organisms, most of the marine flocs, algae, plankton and some microorganisms are separated from the seawater and discharged from the lower part of the cyclone separator. , return to the local sea area, and clean seawater flows out from the upper part after separation.

[0043] Ultraviolet sterilizers inactivate microorganisms...

Abstract

The invention provides an efficient ship ballast water treating system which is mainly used for treating marine organisms in the ballast water of large ships, specifically ocean vessels to remove the effect and damage to the different ocean environments and organisms, belonging to the technical field of environmental protection. The system mainly comprises: a sea water pump, a filter and an ultraviolet sterilizer, etc, wherein the filter utilizes a rotational flow separator to separate the marine organisms, the algae, the planktont and the suspended particle in the sea water through gravity and centrifugal force. The ultraviolet sterilizer can kill the microorganisms (such as bacteria, virus etc) in the water; the discharged water can reach the D-2 discharging standard requirement of the International Ship Ballast Water and Sediment Control and Management Convention. The system has a high removing effect to the marine organisms, the bacterial and the virus in the ballast water; the system does not generate daily substances and dose not have the secondary pollution to the ocean.

Description

technical field [0001] The invention clarifies an efficient ballast water treatment system for ships, which is mainly used for the treatment of marine organisms and microorganisms in the ballast water of large ships (especially ocean-going ships), and eliminates its impact on the marine environment in different places and ecological damage. Environmental technology field. Background technique [0002] The ship's ballast water is the sea water carried by the ship for its own safety when sailing with no load or light load. Ballast operation refers to the operation of the ship to inject and discharge ballast water into the ballast tank. Through the ballast operation, the draft and stability of the ship can be adjusted, the hull deformation and navigation resistance can be reduced, the vibration of the hull can be reduced, and the seaworthiness of the ship can be improved. Ballasting is a necessary condition for safe navigation of the ship. [0003] With the development of the ...
