Description

Purification device for lake or river

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lake and river purification apparatus, and more particularly, to a lake and a river water treatment apparatus for purifying sediments and the like which are supplied to a lake and a river under ozone gas.

The lake plays a role of preventing disasters in the case of floods and floods, or preventing pollutants from flowing out to adjacent water systems in advance. The lake also serves as a landscape element responsible for part of the surrounding landscape composition. However, in the case of early rainfall in the lake, it may be caused by influx of leachate such as pesticide and fertilizer, inflow of deciduous decay, inflow of non-point pollutant, and influx of sewage treatment water, and in the warm period such as summer, Due to the eutrophication caused by the vegetation, green algae phenomenon occurs, resulting in malodorous and insect pests, and the function as the landscape element is also lost.

Accordingly, a treatment facility capable of purifying water and maintaining water quality in lakes and rivers has been developed steadily. Conventionally, when the water quality of the lake and the river is purified through the coagulation sedimentation method, the area required for the facility is considerably large, which is unsuitable for the purpose of purifying water at the lake level. Therefore, recently, a purifier which draws water from a lake or a river and filters it out and supplies oxygen and the like again has been developed, but it has a problem in that it is inferior in economical efficiency in terms of inflow and discharge of water.

If ozone gas is dissolved in water, radicals can be generated. The radicals have a sterilizing action and the water treatment apparatus can purify polluted water by using ozone gas which generates such radicals. For example, organic matter can be deposited on the bottom of the lake and cause green tides in the summer. The deposited organic matter must be purified before the lake can be cleanly managed. Water treatment equipment can be used to manage lake water quality.

A general water treatment apparatus generates ozone to purify ozone water containing ozone gas by injecting it into the contaminated water. The water treatment apparatus uses a large-capacity ozone generator since a large amount of polluted water must be purified. The large capacity ozone generator applied to the water treatment system can exhibit different purifying performance depending on the usage ratio.

However, in the case of the water treatment apparatus using ozone to date, the purification ability is remarkably different depending on the specific substance or condition, and the purification effect is not achieved because the water treatment area is very wide especially when applying ozone gas such as a lake or a stream .

Accordingly, the present inventor has developed a method for purifying water quality by oxidizing sediments of lakes and streams using ozone gas. Particularly, there are a high-voltage ozone generator and a high-frequency ozone generator for generating ozone, and it has been found that mixed ozone gas produced through two ozone generators has an excellent effect for purifying water.
