Device for treating ship ballast water

Abstract

The invention relates to the technical field of environmental protection, in particular to an efficient and low power consumption ballast water treatment device. The device contains a sea chest (101), a ballast pump (102), a salinity sensor or conductivity sensor (103), a filter (104), an equipment under test (EUT) (105), a control unit (106), an EUT power supply (107), a water outlet (108), a ballast tank (109), a filter sewage outlet (110), a valve (111), a tubular reverse osmosis (TRO) device (112), a flow detection unit (113) and a pipe, wherein the inside of the filter (104) is provided with a sterilization system; the sterilization system contains a sterilization system consisting of a solid light-emitting diode (LED) ultraviolet lamp and / or a sterilization system combining a solid LED ultraviolet lamp with photocatalysis; and the solid LED ultraviolet lamp is a hollow triangular prism or quadrangular prism type ultraviolet lamp. The device of the invention has the advantages of low power consumption, high efficiency, convenient installation and no pollution.

Description

A device for treating ship's ballast water technical field The invention relates to the technical field of water treatment and environmental protection, in particular to a device for treating ship ballast water with high efficiency and low power consumption. Background technique One of the four major threats facing the marine environment today is from the invasive spread of harmful organisms, and ship ballast water is the most important way of spreading harmful organisms. Treating ship's ballast water is the best way to solve the pest invasion caused by ballast water. The International Maritime Organization (IMO) pointed out that the control of pest invasion in ship's ballast water is a focus of global attention. It does not advocate the use of different governance systems in different regions to control ballast water. The basic requirements are: treatment on board; cost-effective, compact equipment , easy to operate; no new pollution to the environment of marine and coa...

Problems solved by technology

Although the method of electrolysis of seawater has a good bactericidal effect, after killing bacteria by electrolysis, it may produce carcinogen chloroform, which will cause secondary pollution to the environment, so this method has always been controversial.

Therefore, in the prior art, there are basically disadvantages such as large equipment cost investment, high energy consumption, and low efficiency of sterilization and algae removal.

The inventor previously introduced a micro-current electrolytic sterilization and algae removal device (patent application number: 200810084187.2). Since this technology uses an electrochemical method, it is difficult for this system to realize the integration of filtration and processing units. Excessive defects
