Problems solved by technology

However, due to the large amount of microorganisms and pathogens contained in the ballast water of ships, they will be brought to all parts of the world with the discharge of ballast water during the voyage. If strict treatment is not carried out before discharge, it may cause the invasion of alien species and the spread of infectious diseases , Destruction of ecological balance and other issues, causing great harm to the global marine environment

Abstract

The invention provides a device for inactivating microorganisms in ship ballast water based on a photoelectrocatalysis principle, the ship ballast water enters a reaction tank through a water inlet, acathode plate, an anode plate and an ultraviolet light source are arranged in the reaction tank, the ship ballast water is inactivated through photoelectrocatalysis, and aeration is carried out in the reaction tank through an aeration device. Different groups of cathode and anode plates are separated from the electric magnetic stirring device through partition plates, a water through hole is formed between the cathode and anode plates for circulation, and treated ship ballast water is discharged through a water outlet. The device is simple in preparation, low in cost, capable of efficiently and quickly inactivating the microorganisms in the ballast water, low in treatment cost, small in occupied area, safe and reliable in equipment and operation, good in economic effect and wide in ship application prospect.

Description

technical field [0001] The invention relates to a device for inactivating microorganisms in ship ballast water based on the principle of photoelectric catalysis, belonging to the field of sewage treatment. Background technique [0002] The ship's ballast water plays a vital role in ensuring the balance, stability and navigation safety of the ship. However, due to the large amount of microorganisms and pathogens contained in the ballast water of ships, they will be brought to all parts of the world with the discharge of ballast water during the voyage. If strict treatment is not carried out before discharge, it may cause the invasion of alien species and the spread of infectious diseases , destroying the ecological balance and other issues, causing great harm to the global marine environment. Therefore, on the basis of the current ballast water treatment technology, it is of great significance to seek a treatment technology with better inactivation effect, higher efficiency,...
