Description

Ozone sterilization water and OH radical generating device and waste water purification, cleaning or sterilization equipment using this system {DISINFECTANT OZONIC WATER AND OH RADICAL GENERATOR, AND SEWAGE PURIFICATION, ABSTERSION OR STERILIZATION SYSTEM USING THE SAME}

 The present invention relates to a device that is applied to water quality improvement, cleaning and sterilization, such as waste water or negative waste water, livestock waste water, food waste water, sewage treatment plant, etc. The present invention relates to an ozone sterilizing water and OH radical generating device and an apparatus for purifying, washing or sterilizing waste water using the same to generate ozone, and to mix and refine it with the recovered water to enable more efficient water purification, cleaning and sterilization.

Generally, algae and aquatic plants living in ponds such as Soho and golf course hazards proliferate depending on inorganic nutrients such as nitrogen and phosphorus dissolved in sunlight, water and water. Inorganic nutrients are contained in rain, irrigation water, do.

However, when the above-mentioned inorganic nutrients continue to be introduced, algae and aquatic plants become excessively prosperous, which leads to an increase in the quality of the eutrophic films, thereby causing red tides. When the red tide phenomenon is neglected, the amount of dissolved oxygen is decreased, and the algae and the like are damaged. The algae and the like are decomposed by aerobic microorganisms. If the water does not flow and stagnates, the oxygen in the water is further deficient as the aerobic microorganism decomposes. When the anaerobic environment is absent or lacking oxygen, the anaerobic microorganisms generate hydrogen sulfide or methane gas, The odor is generated.

Generally, as a method for improving water quality such as soho and river, a method of increasing the amount of aerobic microorganisms by increasing the amount of dissolved oxygen in water by installing air diffusers in the deep part by using a blower has been used.

However, the method using the blower has a disadvantage in that the utilization of the air diffuser is poor and the supply of dissolved oxygen is not smooth, so that the water quality improvement effect is less than the facility investment. Particularly, in summer, green algae multiply, polluting the soho as a whole, and generate odors, which is not suitable as a solution.

In addition, the golf course Soho and water hazards are used as obstacles along with the landscape of the fields. These ponds are used to prevent the water from penetrating into the ground and to reduce the flow rate or to prevent backflow to the field. Water-repellent treatment causes water corruption to proceed rapidly. Moreover, the use of excessive pesticides is often used to control the field or green grass, so the residual pesticide penetrates into the pond, further exacerbating water quality.

Conventionally, a method of preventing pollution of a pond by applying a fountain to a pond or using a special enzyme has been applied in the related art. However, since a fountain is merely a function of circulating water, it has a remarkable effect to purify a pollutant And the use of special enzymes is effective in removing contaminants, but it has a drawback in that it is expensive.

As a conventional method for solving the above-mentioned problems, Korean Patent Laid-Open No. 10-2007-0062060 discloses a method in which a planting bag in which submerged plants can grow and a net containing charcoal are connected to each other to form an integral body Respectively. However, with this configuration, it is impossible to purify the water of the hazard within the golf course as a whole, and the effect can be expected only within the local range. In addition, in order to purify or improve the water of the entire hazard, a large quantity of planting pouches must be supplied, which makes it difficult to install and maintain the planting pouch, and periodic replacement, exchange or maintenance of the planting pouch should be performed periodically. There is a problem that the maintenance and management cost is increased.

 The present invention was developed to solve the above-mentioned problems, by generating ozone using air and oxygen, and mixing and refining it with recovered water to provide an odorless ozone sterilizing water including microbubbles and OH radicals.
