Description

WATER QUALITY IMPROVEMENT SYSTEM USING OZONE SUPPLY UNIT AND MICRO BUBBLE}

The present invention relates to a water quality improvement system capable of improving water quality using an ozone supply unit and micro bubbles. More specifically, gas such as ozone and oxygen is ejected into water using a pipe diffuser in the size of a micro bubble. The present invention relates to a water quality improvement system using an ozone supply unit and micro bubbles that can alleviate or eliminate the occurrence of algae (especially cyanobacteria and red algae) that occur in large quantities in an appeal to increase water pollution.

The demand for the use of appeals and rivers as water is increasing due to the increase in population and industrialization. However, such industrialization and urbanization have rapidly increased the pollution load on water resources, resulting in worsening water pollution.

In particular, in the case of rivers or rivers, the degree of pollution continues to increase due to the environment in which the pollutants discarded are concentrated.

In addition, due to the climatic characteristics of Korea, many rains have been concentrated in summer, and many dams have been constructed to secure such heavy rains as water resources. Since artificial lakes created to secure water resources become stagnant waters with a longer hydraulic residence time, the concentration of nutrients such as nitrogen or phosphorus is generally increased instead of having less organic matter.

Due to the appealing environment that provides the proper environment and rich nutrients for algae growth in the appeal, the ideal excessive algal growth and eutrophication are emerging as serious environmental problems, and fundamental measures are needed for such causes.

Problems caused by the surge of algae in the lake can lead to complaints not only by the coloring of the water source but also by taste and odor from the secretion of enzymes in vitro. THMs) can threaten the health of citizens who use it as a drinking water source, and such an excess of algae causes flocculation and sedimentation in addition to economic losses such as increased maintenance costs due to deterioration of mechanical facilities and piping and mechanical functions during water treatment. Increasing backwashing due to impedement, filter closures or shortening of filter paper durations is a serious obstacle to water treatment systems and can result in significant damage to maintenance in existing treatment systems.

As a general countermeasure, to remove algae generated in freshwater lakes, the soil is sprayed and then sedimented with a cutlery, and a fine air generator is mounted on the cutlery to lift and remove algae with the fine air. A method of killing by heavy metal spraying, a copper solution (Cu ²⁺ ), a method of killing by a fungicide such as sodium chloride (NaClO), a method of removing by using an inorganic oxide such as zeolite, and There is a method of collecting by the physical method after the algae injury by aerosol, and the method of spraying the natural microorganisms after cultivating the natural microorganisms, but most of the methods are used to settle by the cutlery, the most commonly used For the economic reasons, the method of spraying ocher powder and sedimenting at the same time as algae adsorption is mobilized for economic reasons.

However, in the method of spraying ocher powder and sedimenting at the same time as algae adsorption, there is a possibility that the water quality ecosystem is destroyed due to the high possibility of secondary water pollution due to sedimentation of the ocher powder adsorbed by algae.

In addition, a method of removing algae by floating algae together with fine air after installing a fine air generating device on a cutlery is used. However, in this case, algae can be removed only in a local body of water, which limits the removal of algae generated in a wide range of water. In the case of the method of killing by a bactericide such as sodium hypochlorite (NaClO), there is a problem that can kill even the microorganisms beneficial to the water ecosystem by hypochlorite, and other inorganic oxides such as zeolite to remove Since the method settles in water, problems similar to those of conventional loess may occur.

Therefore, in order to solve the problems caused by algae, systematic research on the fundamental causes and preventive measures of eutrophication due to the rapid growth of algae, and the on-site removal of algae generated in appeals or rivers is required.

Republic of Korea Patent No. 10-1123256 (announced on March 21, 2012) Republic of Korea Patent No. 10-1429033 (August 12, 2014 announcement) Republic of Korea Patent Publication No. 10-2018-0005124 (published Jan. 15, 2018) Republic of Korea Patent No. 10-1528712 (2015.06.15 announcement)

In other words, the present invention provides a burst of energy that occurs when a burst in the water the microbubbles, OH is generated by the high-temperature high-pressure ^- and the number lake by using the available ozone sterilization in, be water sources, agricultural, such as a river or water source Green algae or red algae generated at the source of the water, and at the fisheries such as the sea and the fish farm can be efficiently removed.

In addition, since the present invention supplies the microbubble sterilized water in a state in which oxygen and ozone are dissolved so that the amount of oxygen is dissolved in the contaminated water, the sterilizing power by ozone and oxygen impregnated in the microbubble is increased.

In addition, in the present invention, since the particle size of the microbubble is 50 µm or less, the microbubble is extinguished in contaminated water requiring sterilization due to low buoyancy and slow flotation speed. Is reduced to 1/2 to lose buoyancy, which contributes to the improvement of the low oxygen level in the bottom, and can be completely dissolved in contaminated water to provide maximum sterilizing power, and do not cause environmental destruction by the remaining ozone. It is not necessary to add chemicals for treatment such as neutralization or flocculation.

In addition, the present invention can contribute to the purification of water quality of the lake because OH- ¹ having strong oxidizing power is generated by the high temperature and high pressure generated instantaneously when bubbles bubbled with oxygen and ozone microbubbles.

If necessary, the plurality of diffusers 90 may be provided with a control valve 95 for adjusting the discharge direction of the micro bubbles supplied from the micro bubble generator 50.

The control valve 95 is connected to each control unit 70, and provides a function to control the micro-bubble circulating for each diffuser 90 and discharged under the control of the control unit 70.

Although it has been described above with reference to the preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention described in the claims below. It will be appreciated.
