Description

Duct Type Ultraviolet Sterilizer Increasing Sterilization Effect for Inside of Pipe}

The present invention relates to a pipeline type ultraviolet sterilizer which increases the sterilization effect inside the pipe, and more specifically, after the complete sterilization of bacteria including Escherichia coli contained in the discharged water before being discharged from the sewage treatment device. In order to increase the disinfection efficiency by spraying air to increase the contact between water and ultraviolet rays to increase the sterilization efficiency, and hard chromium plating on the inside of the casing to reflect the light of the lamp to increase the disinfection efficiency and performance. It relates to a type ultraviolet sterilizer.

Due to the rapid development of industrial society and the improvement of living standards, a large amount of waste water is generated due to the rapid increase in the use of water.In recent years, uncleaned waste water flows into rivers and groundwater, and viruses are detected in tap water and drinking contaminated ground water. Disinfection and purification of wastewater, such as waterborne infectious diseases, are becoming a social problem.

Currently used water treatment technologies include biological treatment techniques using microorganisms and physicochemical treatment techniques such as filtration, flocculation, sedimentation or adsorption, but biological treatment techniques are expensive to construct and difficult to remove hardly degradable contaminants. Chemical treatment technology has the disadvantage of not only high operating cost but also a large amount of sludge.

On the other hand, chlorine disinfection, which has been widely used in water treatment plants, generates THM (Trihalomethanes) substances harmful to the human body in the treated water and has a disadvantage in that it cannot remove chlorine-based organic compounds emitted from various industries. Therefore, in order to remove such hardly decomposable substances, some treatment plants use activated carbon adsorption and ozone oxidation, but activated carbon adsorption may be contaminated by physical adsorption, and ozone oxidation is easy to produce byproducts when oxidizing hardly decomposable organic matter and bromine (Br). ) Produces a compound.

Accordingly, in recent years, ultraviolet disinfection that can sterilize pathogenic bacteria and harmful microorganisms without causing secondary pollution has attracted attention.

Ultraviolet light is a wavelength of 200 ~ 400nm, which is directly adjacent to the violet end of visible light, and invisible light area shorter than visible light damages the cell wall of bacteria, alters cell permeability, plasma colloidal properties, and inhibits enzyme activity. It kills bacteria by damaging the cell's DNA and RNA.

However, the ultraviolet disinfection technique has a problem in maintenance because the short distance of ultraviolet rays is required in water, and thus the number of ultraviolet lamps and periodic cleaning of contaminants on the surface of the ultraviolet lamps are required to process an appropriate amount.

In addition, UV sterilization may kill pathogenic microorganisms, but there is a limit in that it is not possible to completely decompose organic materials.

In order to promote decomposition of the organic material, a photocatalytic material that reacts with ultraviolet rays is used, but this also has a problem in that light transmittance is lowered as sludge or contaminants adhere to the surface of the ultraviolet lamp over time.

In the hydroponic facility, sewage treatment plant, and aquaculture farm, sewage and wastewater with a higher concentration of suspended solids in the treated water than the constant water such as sewage and sewage can be deposited quickly on the surface of the quartz glass tube protecting the UV lamp. As it is scaled, it is desirable to clean the quartz glass tube surface at least one hour apart.

If the washing is left unattended for a long time, the amount of ultraviolet rays irradiated to the microorganisms decreases, and the sterilization treatment efficiency rapidly decreases, and the quartz glass tube is discolored and needs to be replaced without replacement.

In addition, in the ultraviolet type sterilizer of the pipeline type, there is a problem in that ultraviolet rays are absorbed and extinguished on the inner wall of the housing, so that it is necessary to be able to reflect to improve the sterilizing effect and performance.

There is a need for a method for increasing the contact of water with ultraviolet light.
