Description

Water treatment system using high efficiency large-capacity ozone generator

The present invention relates to a water treatment system using a high-efficiency, large-capacity ozone generator, and more particularly, to a high-efficiency, large-capacity that can generate and supply ozone to the system in large-capacity in treating miscellaneous wastewater collected from a distribution tank through a microfilter to a flow control tank. It is about a water treatment system using an ozone generator.

In general, as a water treatment technology for purifying wastewater, physicochemical treatment methods such as filtration, precipitation, and adsorption, and biological treatment methods using microorganisms are mainly used.

The physical and chemical treatment method has the disadvantages of requiring a large amount of chemicals and high operating cost. Although the biological treatment method using microorganisms is an eco-friendly treatment technology, the process is complicated and large-scale aeration tanks and sedimentation tanks are required, so a lot of facility space is required. In recent years, advanced oxidation treatment technology is being used because it is required, it takes a lot of time and money to construct, and it is not possible to easily purify the recalcitrant organic components of sewage and wastewater.

Advanced Oxidation Process (AOP) is a technology that decomposes organic compounds contained in wastewater into harmless compounds such as CO2, H2O, or O2 by generating OH radicals. Various types of technologies such as oxidation and oxidation by catalyst materials have been developed.

Advanced Oxidation Process (AOP) includes ozone(O3)/UV AOP(Advanced Oxidation Process), ozone(O3)/hydrogen peroxide(H2O2)(Peroxone AOP), hydrogen peroxide(H2O2)/UV AOP(Advanced Oxidation Process) ), AOP (Advanced Oxidation Process) using photocatalyst, ozone (O3)/High PH AOP (Advanced Oxidation Process), and hydrogen peroxide/iron salt AOP (Advanced Oxidation Process) technologies have been developed.

Meanwhile, among the advanced oxidation treatment technologies described above, the water treatment technology using ozone (O3)/hydrogen peroxide (H2O2) (Peroxone AOP) has excellent oxidizing power of relatively difficult-to-decompose organic substances, and the ozone remaining in the treatment process is combined with hydrogen peroxide (H2O2). Therefore, it has the characteristic of accelerating ozone decomposition and is widely used.
