Embodiment Construction

[0049] The present invention will be further described below in conjunction with accompanying drawing.

[0050] figure 1As shown, a ship ballast water treatment system includes an electric control box 1, a sea valve 2, a seawater coarse filter 3, a ballast water pump 4, a three-way drain valve 5, a mechanical filter 8, a microfiltration membrane filter 9, Nitrogen generator 6, nitrogen water mixer 7 and ballast tank 10. One end of the sea valve 2 is connected to seawater, and the other end is connected to the ballast water pump 4 through the seawater coarse filter 3, and the ballast water pump 4 is connected to the nitrogen-water mixer 7 through the mechanical filter 8 and the microfiltration membrane filter 9 in turn, and the nitrogen generator 6 The nitrogen-water mixer 7 is connected, and the nitrogen-water mixer is connected to the ballast tank 10, and the ballast tank 10 is provided with a third exhaust valve 101; the bottom of the ballast tank 10 is connected to the...

Abstract

The invention relates to a marine ballast water treatment system which comprises a kingston valve, a seawater coarse filter, a ballast water pump, a seawater fine filter and a ballast tank, wherein the kingston valve is communicated with the ballast tank by sequentially passing the seawater coarse filter, the ballast water pump, a mechanical filter, a microfiltration membrane filter and the seawater fine filter, a nitrogen producing device is used for supplying nitrogen to seawater via a nitrogen and water mixer, and microbes comprising sediment and organic matters in ballast water can be separated and treated so as to inhibit the growth of the residual microbes and bacteria and meet a strict discharge standard; and furthermore, the system has an automatic cleaning function, is convenientto use, maintenance-free and long in service life, and can be used for saving the use cost.

Description

technical field [0001] The invention relates to a ship ballast water treatment system. Background technique [0002] At present, the marine environment is being threatened by four major threats: the invasion of alien organisms; the discharge of land-based pollution; overfishing of marine resources and the destruction of marine habitats. With the rapid development of the world's shipping industry and the rapid increase of the tonnage of ships, about 3 to 5 billion tons of ship ballast water are transferred from one port to another every year, and the alien organisms brought in are one of them. [0003] When a ship is loading and unloading cargo, the center of gravity and buoyancy of the ship are constantly changing. For the draft, balance and inclination of the ship, it is necessary to inject seawater into the ballast tank when it is lightly loaded; to overboard. This is the migration of ballast water. Alien organisms lack natural enemies in the local area, and they flood w...
