Embodiment Construction

[0019] The technical solutions of the embodiments of the present invention are described in detail below with reference to the drawings.

[0020] Such as figure 1 As shown, the ballast water to be discharged first passes through a filtering ultrasonic unit to filter out aquatic organisms, solid particles and impurities larger than 40 μm; after pretreatment by the filtering ultrasonic unit, the ballast water passes through the ultraviolet ultrasonic processing unit, which is mechanically affected by the ultrasonic Under conditions, the bacteria, algae and protozoa in the seawater are killed, while the smaller bacteria and pathogens are killed by ultraviolet rays; finally the treated ballast water is discharged out of the cabin.

[0021] Such as figure 2 Shown is a schematic structural diagram of an embodiment of the ship's ballast water treatment equipment of the present invention. The untreated ship's ballast water in the ballast tank 1 is first pumped out by the water pump 3, wh...

Abstract

The invention which belongs to the field of ship ballast water processing equipment especially relates to a method and an apparatus for processing ship ballast water through filtration, ultraviolet and ultrasound. The apparatus of the invention comprises a water pump, a pressure transducer, a flowmeter, a filter, a comprehensive processing unit of ultraviolet and ultrasound, a control system, an electromagnetic valve and a pipeline. Water enters the filter through the water pump, then enters the comprehensive processing unit of ultraviolet and ultrasound to be subjected to biological inactivation, and is finally discharged. The synergetic disinfection of the ultraviolet-ultrasound unit allows the disinfection effect to be good, ultrasonic waves destroy protective layers of microbes, the ultraviolet radiation destroys DNA and RNA of the microbes, and the ultrasonic waves have certain cleaning effects on ultraviolet lamps. The apparatus of the invention, which can effectively kill the microbes in the ship ballast water, has the advantages of low energy consumption, high reliability, simple operation and maintenance, realization of one-key operation through an automatic control unit, and flexible selection of an installation platform according to practical cases.

Description

Technical field [0001] The invention belongs to the field of ship ballast water treatment equipment, and particularly relates to a filtration and ultraviolet ultrasonic ship ballast water treatment method and equipment. Background technique [0002] The threats facing the earth's marine environment can be roughly summarized into four major categories: invasion of other marine ecosystems by marine organisms; marine pollution originating from land; overfishing of marine resources and physical damage to marine habitats destroy. Among them, ships are considered to have caused the invasion of marine organisms into other marine ecosystems. The reason is the marine organisms contained in the ballast water of the ship and the marine organisms attached to the hull. Ship ballast water is the main way for the off-site spread of marine organisms between geographically isolated water bodies. More than 80% of the world's commodity trade is transported by ships, and approximately 3 to 5 ...
