Background

Pure water is the most basic chemical solvent, and is the most widely required by human production, life and scientific research activities. The removal of organic substances from pure water is generally carried out by using the technologies of activated carbon adsorption/reverse osmosis/185 nm ultraviolet lamp photo-oxidation and the like. Among them, for removing trace organic substances (below 50 ppb) in ultrapure water, 185nm mercury lamps are adopted in most processes of water treatment equipment. The processing technology has large volume and energy consumption.

On the other hand, the development of LED deep ultraviolet components is changing day by day, and the LED deep ultraviolet components are now widely used in the fields of ultraviolet curing and environmental germicidal lamps. The LED component has the advantages of small volume, high output power, multiple parallel connection and the like. However, the wavelength limit of deep ultraviolet of the LED is still in the UV-C wave band, which is about 240 nm. No 185nm wavelength LED ultraviolet component is available at present, and the application range of the technology in organic matter treatment is limited.

The index of TOC (abbreviation of Total Organic Carbon) content indicates the monitoring of water pollution in a certain sense. Various organic pollutants, microbes and bacterial endotoxin are catalytically oxidized into carbon dioxide, so that the electric conductivity of water is changed, and the data of the electric conductivity is converted into the total organic carbon. If the total organic carbon is controlled at a lower level, it means that the contamination of organic matter, microorganisms and bacterial endotoxins in the water is in a better controlled state.

SUMMERY OF THE UTILITY MODEL

To sum up, the utility model discloses a what solve current pure water treatment facility's technology and adopted is that 185nm mercury lamp exists that volume and energy consumption are all great to and the wavelength of simple LED ultraviolet subassembly can't satisfy the not enough technique of demand, and propose pure water TOC processing apparatus.
