Abstract

PURPOSE:To progress metabolism activity of photosynthesis bacteria, etc., and to clean water by irradiating a cleaning area for >=2 hours a day at >=50 lux by a light source installed on or in the water in the night time and in a rainy day or cloudy day. CONSTITUTION:The living activities of the bacteria, such as photosynthesis bacteria, single-cell living things, such as water-blooms, diatoms, green algae, etc., living in water are vigorous and the cleaning of the water by the metabolism activities thereof progresses in the daytime when there is light. The cleaning does not, however, progress any longer when the irradiation quantity of light decreases. In addition, the photosynthesis bacteria, the single-cell living things, such as water-blooms, and the green algae, etc., do not make photosynthesis any longer and the oxygen is eventually not generated. The decomposition and removal of the pollutants are not progressed any more and the dissolved oxygen in the water is held decreased. The irradiation time of light is, thereupon, increased to progress the metabolism activities of these living things by the artificial illumination. As a result, the dissolved oxygen in the water is increased and the decomposition of the org. matter by aerobic bacteria is activated. The cleaning of the water is thus progressed.

[Industrial Field of Application] The present invention is a water purification method for ponds, fish farms, lakes, etc. [Conventional technology] In water bodies such as reservoir ponds, fish farms, lakes, and marshes where water exchange is low, especially in the deep layers, oxygen is deficient in the water, the ability of aerobic bacteria to decompose organic matter decreases, and saprophylaxis progresses. water quality is declining. The deterioration in water quality is a sanitary problem and also causes a poor appearance, so to prevent this, for example, water replacement, cleaning, and spraying of chemicals are carried out.

However, in large lakes and ponds, operations such as water replacement and cleaning require manpower and expense, making it economically problematic to perform them regularly. Additionally, chemicals that can affect the human body cannot be sprayed on reservoirs or dams used for drinking water, so there is currently a need for a low-cost and simple water purification method.

The present invention solves the above problems and provides a low cost and simple water purification method. In other words, the present invention provides water treatment by irradiating the target purification area with light of 50 lux or more for 2 hours/day or more using a light source installed on or in the water during the night when no light is irradiated and during the daytime during bad weather such as rainy or cloudy days. It is a method of purifying. The water purification method of the present invention is suitable for areas such as reservoir ponds, fish farms, lakes and marshes where water exchange is relatively small and water quality tends to deteriorate. The time to use the purification method of the present invention is when the amount of sunlight irradiating the water surface is less than 50 lux, such as at night when sunlight is not irradiated, or during rainy or cloudy days, even during the day. The light source used in the present invention is not limited in shape, etc., as long as it can irradiate light to the required area with the necessary brightness, and the wavelength is normal visible light, such as a commonly used electric light. However, if it is installed underwater, consideration must be given to waterproofing, etc. In the present invention, the light source is installed above the water and irradiates light toward the water surface when the water depth is shallow (when the light reaches the bottom sufficiently), but when the water depth is deep and it is difficult for the light to reach the bottom, or when the water transparency is low. In some cases, a light source is installed underwater or both underwater and above the water to irradiate the area.Also, in cases of rotting conditions or extremely low water transparency, light cannot reach the interior, so light sources are installed around the area. As the purification progresses, the light source and light intensity may be gradually changed.The number of light sources and the installation location may be changed as appropriate depending on the water quality and surrounding shape.In the present invention, the light irradiation time is as follows: It varies depending on the change in sunlight hours depending on the season, but even in the summer when the hours of sunlight are long, there are 2 times a day.
It takes at least 5 to 6 hours, preferably at least 5 to 6 hours.

[Effect] Bacteria such as photosynthetic bacteria, single-celled organisms such as Aphids, protozoa, diatoms, and green algae that live in water are active during the day when there is light, and water purification progresses through their metabolic activities. However, during the day when there is no light or the weather is bad and the amount of light irradiated is low, metabolic activity weakens and purification does not proceed. In addition, photosynthetic bacteria, single cells such as Acropora, and green algae no longer perform photosynthesis, and as a result, oxygen is not produced, and the decomposition and removal of pollutants do not proceed, and the amount of dissolved oxygen in the water remains low. The present invention increases the irradiation time of light by irradiating light with artificial lighting at night or during bad weather to advance the metabolic activities of these organisms. As a result, the amount of dissolved oxygen in the water increases, the decomposition of organic matter by aerobic bacteria becomes active, and water purification progresses. [Example J] A specific example of the present invention will be shown below, but the present invention is not limited thereto. Area at average water level: 100s'', deepest part: 5cm, volume: 500cm
At the bottom of the pond in KJ, 5clI of saproplastic mud had accumulated. Ten light sources were installed so that the entire water surface of this pond was irradiated with 1,000 lux of light, and the light was irradiated continuously at night, on rainy days, and during the day on cloudy days6. After the rows started to decrease, the saproplastic sludge completely disappeared, the water became clearer, and no more saproulic sludge was produced. [Effects of the Invention] As explained above, the water purification method of the present invention can purify water by simply installing a light source, and once the light source is installed, light irradiation can be continued. Since the water is constantly purified, there is no need to worry about the quality of the water deteriorating, and it is very simple and economical since it only requires electricity.
