Description

Ozone oxidation water treatment system

The present invention relates to a water treatment system using an ozone dissolution oxidation device that treats water with ozone. In particular, ozone is injected into water, water and ozone are mixed to dissolve the water, and the oxidation action is performed through contact and reaction processes. It relates to a water treatment system that can realize effective water purification and wastewater treatment.

In general, oxygen is indispensable to water, and when oxygen is insufficient in water, it becomes an environment in which living things cannot reproduce in water, and the ecosystem of animals and plants living in water will collapse.

Therefore, in order to improve such a situation, it is required to prevent the inflow of contaminants and artificially supply oxygen at the same time.

On the other hand, ozone has strong oxidation and sterilization ability compared to chlorine, reaction time is short, and it is directly reduced to oxygen without generating trihalomethane after reaction. Its use is expanding in every field.

In particular, most of the intermediate products or reaction products produced as a result of the reaction of ozone and natural organic matter are substances that can be decomposed, reused, and treated during the water source cycle of natural ecosystems, and have great benefits for the ecosystem or the environment.

Recently, technologies related to the domestic and foreign environmental industries have advanced rapidly, so BOD, SS, and COD treatment in the water treatment field have been researched and developed to the extent that there is no problem. Methods are being developed, and the time has come when sewage or wastewater must be treated and reused for water resources that are gradually polluted and depleted, and more advanced treatment in disinfection treatment to prevent water-borne infectious diseases in water purification treatment is in need of.

That is, ozone-dissolved water uses strong oxidizing power to disinfect, sterilize, and decompose or detoxify water pollutants. For example, when harmful organic matter is completely oxidized, carbon dioxide (CO2), water (H2O), nitrogen (N2) gas, etc., and water-soluble metal ions such as iron (Fe +2) and manganese (Mn +2) can be removed as insoluble hydroxides, and pollutants are decomposed into CO2 or H2O by ozone. Comply with BOD and COD.

Oxidation division provided in the form of a partition wall on one side divided into quadrants in a direction perpendicular to the direction in which dissolved water is supplied so as to divide the division to which the dissolved water of the ozone dissolving unit is supplied and the division to be discharged after oxidation among the divisions dividing the interior of the oxidation tank septum;
A treatment in which the oxidation dividing partition wall has a first oxidation space in which the contact frame is installed as a region to which dissolved water is supplied by blocking the position at right angles to the direction in which the dissolved water is supplied, and the lower part is opened and passed through the contact frame a first partition wall through which the number is moved;
The second oxidation tank is disposed on one side extending from the oxidation partition partition to the other side divided by the first partition partition wall of the oxidation tank and overflows to the top to supply treated water moving in the first oxidation space with an open top. a second partition wall blocking to have a space; and
A partition wall dividing the partition divided by the oxidation dividing partition wall and the second dividing partition wall of the oxidation tank into a third oxidation space connected to the second oxidation space and a discharge circulation space in which the discharge pipe and the circulating part of the mixing circulation part are connected a third partition wall provided in the form of a third partition wall to block the lower portion of the treated water overflowing from the upper portion through the second oxidation space and flowing into the third oxidation space from being opened in order to move to the lower portion into the discharge circulation space; doing
Ozone oxidation water treatment system.
