The present invention can increase the oxygen solubility to expand the aerobic region and improve the water treatment ability as well as induce anaerobic water treatment mechanisms, as well as flow artificial islands using useful microorganisms that can significantly increase the water treatment efficiency It is about.

In general, artificial vegetation islands capable of plant growth are newly illuminated facilities in areas related to natural ecosystems such as landscape architecture, botany, and ecology in that they create new forms of aquatic ecosystems.

Artificial vegetation islands exist naturally in nature, and the peat layer is floated by gas, or part of the lake has been cut off and floated on a lake or swamp. .

It was also first introduced by Hoeger in Germany in 1979 under the name of schwimmkampen (floating campus), and extensive research began in Japan since the mid-1990s.

Artificial vegetation islands are emerging as new facilities in that they have the benefits of creating and improving the reproductive environment of waterfowl and fish families, contributing to improving the waterside landscape, anticipating water purification effects, preventing erosion from rafts by blue waves, and preventing waterborne infectious diseases. I am getting it.

In addition, it is possible to create a vegetation community in the water surface with severe water level fluctuations, create a flat vegetation environment on the shore of the steep slope, and cover the bare ground exposed by the water level fluctuation, and provide a land environment at a deep water depth. Of course, it can provide a shelter inaccessible to humans and land animals.

Artificial islands as described above are configured to absorb nutrients from the water by absorbing inorganic nutrients that cause eutrophication through plant roots while growing aquatic plants planted on artificial plant islands.

In addition, by having a function of adsorbing, decomposing, and precipitating suspended matter and organic matter, it is possible to decompose and remove organic matter, thereby reducing turbidity of water.

However, research on the proper area required for water quality improvement effect and water quality improvement by the plant island is insignificant.

In addition, the water purification mechanism of the artificial island is in a form of using a flora, and it is difficult to expect a certain water quality improvement effect in the form of a year depending on seasonal influences and the characteristics of aquatic plants.

Therefore, the present inventors can increase the oxygen solubility to increase the aerobic area and improve the water treatment ability, as well as induce anaerobic water treatment mechanisms, as well as useful microbial flow artificial islands that can significantly increase the water treatment efficiency. I would like to propose.

1 is a schematic view showing a flow artificial island using the useful microorganism of an embodiment of the present invention.

As shown in FIG. 1, a flow artificial island using useful microorganisms, which is an embodiment of the present invention, uses a useful microorganism carrier and a useful microorganism-treated volcanic stone as a filter medium in Jeonju University, as a filter medium. Filling,

The filter medium filling tank 1 filled with the filter medium is provided in the filter bed 3 installed in the water of the water treatment target water to treat the water treatment target water.

Meanwhile, the water to be treated may mean a large amount of water stored in a reservoir or a dam, but is not necessarily limited thereto.

Here, the useful microorganism-treated volcanic stone is immersed in a volume ratio of 1: 0.4 ~ 0.7 volcanic stone such as raw or black bean in culture water mixed with 49% by weight of distilled water, 49% by weight of useful microbial stock solution and 2% by weight of sugar. It is good to ferment for 10 to 21 days at a temperature of 30 ~ 37 ℃ in the state.

If the volcanic stone is immersed in the culture water at a volume ratio of less than 1: 0.4 for 10 days at a temperature of 30 to 37 ° C., there is a problem in that yeast, lactic acid bacteria and photosynthetic bacteria are not evenly formed in the volcanic stone. .

When the volcanic stone is immersed in the culture water at a volume ratio of more than 1: 0.7 and fermented at a temperature of 30 to 37 ° C. for more than 21 days, the yeast, lactic acid bacteria and photosynthetic bacteria are excessively formed in the volcanic stone, thereby causing 3) there is a problem that the air is not supplied smoothly.

Therefore, not only yeast, lactic acid bacteria and photosynthetic bacteria can be more evenly formed in the useful microorganism carrier and the useful microorganism treated volcanic stone, and in order to allow the air to be more smoothly supplied to the filter bed 3,

The useful microorganism-treated volcanic stone is a temperature of 30 ~ 37 ℃ in a state in which volcanic stone is immersed in a volume ratio of 1: 0.4 ~ 0.7 in the culture water mixed with 49% by weight of distilled water, 49% by weight of the useful microbial stock solution and 2% by weight sugar. It is preferable to ferment for 10 to 21 days.

2 is a configuration diagram schematically showing a state of the filter medium filling tank 1, and FIG. 3 is a configuration diagram schematically showing a state of the filter image 3.

Here, the filter medium filling tank 1 may be filled with 5 to 50 parts by weight of the useful microorganism carrier and 45 to 450 parts by weight of the useful microorganism treated volcanic stone with respect to 100 parts by weight of water to be treated.

When less than 5 parts by weight of the useful microorganism carrier is filled with less than 45 parts by weight of the useful microorganism-treated volcanic stone, the chance of adsorption of nutrients such as nitrogen and phosphorus is reduced and useful microorganisms or water treatment Lack of attachment space for microorganisms,

There is a problem that the opportunity for anaerobic biological water treatment is reduced due to the reduction of the anaerobic region in the useful microbial carrier.

When the useful microorganism carrier is filled in excess of 50 parts by weight with respect to 100 parts by weight of the water to be treated, and the useful microorganism-treated volcanic stone is filled in excess of 450 parts by weight, the internal circulation rate during the circulation of the water to be treated in the filter bed (3) Proceeding to this 100%, there is a problem that there is a concern that the treatment efficiency of the water treatment target water outside the filter (3) is significantly reduced.

When the upper part of the filter bed 3 maintains a level change of less than 10 cm above and below the water surface of the water to be treated, the treatment efficiency of the carbon powder due to aerobic oxidation is significantly reduced due to the decrease of the unsaturated flow zone during the treatment of the circulating water. There is a problem.

When the upper part of the filter bed 3 maintains a water level change of more than 20 cm above and below the water surface of the water to be treated, the control efficiency of the nitrogen content is remarkably reduced due to the reduction of the saturated flow area in the filter bed 3 where anaerobic areas are formed. There is a problem that is reduced.

Therefore, by allowing the filter bed 3 to move on the surface of the water to be treated, oxygen solubility can be increased to not only expand the aerobic region and improve the water treatment ability, but also to induce anaerobic water treatment mechanisms. sure,
