Apparatus For Purifying Waste Water Using Ozone

The present invention is ozone (O ₃₎ to the waste water purification relates to an apparatus, in particular, sewage or waste water purification device using ozone (O ₃₎ with various kinds of waste water can be purified process using ozone (O ₃₎ of the sewage, such as using It is about.

Today, due to the rapid development of the industrial society and the improvement of living standards, the use of water has increased, and a large amount of waste water is generated.In recent years, poorly disinfected waste water is introduced into rivers and groundwater, and viruses are detected in tap water and drinking contaminated ground water. Disinfection and purification of wastewater has become a social problem, such as a person suffering from water-borne infections.

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. Physicochemical treatment technology not only requires a lot of operating costs but also has a disadvantage of causing 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. However, activated carbon adsorption may be contaminated by physical adsorption. ) Produces a compound.

Accordingly, in recent years, ultraviolet disinfection that can sterilize pathogenic bacteria and harmful microorganisms without causing secondary pollution has attracted attention. This ultraviolet disinfection action is to sterilize bacteria or microorganisms that may survive in the effluent by irradiating the microorganisms with ultraviolet rays having a main wavelength of 253.7 nm to destroy the microorganism's DNA or inhibit the proliferative action. 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 the decomposition of organic materials, photocatalysts reacting with ultraviolet rays are used. However, when sludge or contaminants adhere to the surface of the UV lamp over time, the light transmittance is lowered and the decomposition efficiency is lowered. There is this.

In addition, conventionally, there is a method of purifying sewage and wastewater using an ion generating device as follows.

First, when a high voltage is applied between the positive electrode and the negative electrode, a discharge occurs between the two electrodes to form an electric field. At this time, free electrons that move freely in the negative electrode are released and move to the opposite electrode, and the released free electrons are in a high energy state, thereby activating various gas components of air existing between the two electrodes. or the like is generated and, while the generated electrons collide with molecules of the gas causes the the outermost electrons of the gas molecules changes a highly reactive radical, where electrons and ions ^-, ozone (O _3), oxygen anion (O ₂₎ Produce new chemical reactions.

This property can be used to decompose contaminating components in fluids. In other words, when ionization gas is injected into the wastewater containing pollutants, the active substances such as radicals, excitation electrons and ions react with the pollutants contained in the wastewater to oxidatively decompose and remove the pollutants. It is called).

In addition, there is a problem that a short occurs at high current and high voltage.
