2. Description of the Related Art While environmental pollution is becoming more serious due to abundant life, various countermeasures for environmental pollution are being taken. Among them, water is used in a wide range of fields from hardness purification treatment of drinking water to wastewater treatment. Attempts are being made to purify. As a means for purifying the water, purification is mainly performed in a septic tank, and the main method is to add chemicals such as a polymer coagulant to raw water to coagulate impurities, and to aggregate the coagulation layer, filtration layer, aeration layer, and activated carbon. Various purifying devices such as treatment are widely used.

The subject of water quality treatment is rivers, lakes, ponds, reservoirs, springs, drains, drains, artificial rivers, canals, canals, aquaculture ponds, garden ponds, golf course ponds, pools, and biotopes. There is a pond, etc., and as a means for purifying these water quality, it is usual to deal with simply replacing dirty raw water with clean water, and as another method, the raw water is circulated through the purification device to remove impurities. A purification method and a means for adsorbing impurities by introducing into a raw water a tubular container or a tank filled with a purification deodorizing material such as activated carbon or charcoal are used.

[0004]

However, in any of the above-mentioned methods of the prior art, rivers, ponds, lakes, swamps, etc. under natural conditions have different amounts of water and mixed amounts of sludge substances and different sludge depending on the region. The water quality varies greatly depending on the components, the inflow of domestic wastewater, impurities from ornaments, oil, etc., and the inflow of organic and inorganic substances due to the soil environment of the land, etc., until the water is completely purified. However, the above-mentioned various methods or treatment methods require a very long time until the purification treatment is completed, and further there is a problem that the purification efficiency is poor.

In the embodiment shown in FIG. 1, the buoyant body 4 is a floating plastic in which air is injected into hard plastic such as polypropylene. this is,
Urethane, which has a lower bulk specific gravity than water, or styrene foam can be used instead. The pipe 5 extending from above the buoyant body to the purification material serves as an inlet for the enzyme solution and the bacterial solution.

In FIG. 2, the wind turbine 6 is attached to the water purification system constructed in FIG. 1 to inject air and oxygen into raw water that is deficient in oxygen due to eutrophication. A wind turbine 8 including a base structure 8 including a plurality of large blades, pulleys, and an air injection bag is installed in the upper center of the buoyancy body 7. This windmill 8 can be replaced by a commonly used windmill,
When the wings rotate due to the wind, the internal pulleys rotate in tandem,
When the rod attached to the pulley moves up and down, the air injection bag that connects the rod and the upper part expands and contracts, and when it expands it takes in outside air into the bag and when it contracts it sends air to water. Then, since natural energy is used as a power without using energy such as electricity, such a structure is desirable.

Inhabit plants 11 such as
The structure where the roots of these plants come into contact with raw water.

When a water turbine is mounted, as shown in FIG. 3, oxygen is supplied by flowing water into raw water in which the amount of oxygen supply is insufficient due to eutrophication. A structure 12 for supporting a water turbine is erected in the upper center of the water purification system of FIG. 1, and the center of the water turbine is connected to the upper part of the structure. If there is no flow of water in a pond or swamp, connect a windmill and let the wind hit

This eliminates unevenness in water quality purification and purifies the water as a whole, thereby purifying at a stable rate.

Next, a method of using the water purification system will be described. The water purification system shown in Fig. 1, Fig. 2, and Fig. 3 is put into ponds and swamps. While the water purification system floats on the surface of the water surface by a buoyant body, the purification material floats on the surface of the water stably due to the weight of the water that enters the water and sinks into the water. After the introduction, organic substances, nitrogen compounds, etc. are decomposed and adsorbed by the purification material and the attached plant, but when the reduction of the purification rate is observed, the enzyme solution or the bacterial solution is injected into the inlet to promote the purification. To inject an enzyme solution or a bacterial solution into a water purification system suspended in a pond or a swamp, go to a water purification system by boat or ship, or
The water purification system is carried out by pulling the water purification system to the lake shore with a string, but it is effective to extend the injection port to the lake shore to avoid the trouble of work.

The present invention is constructed as described above and has the following effects. INDUSTRIAL APPLICABILITY The present invention is to purify water quality by having a plurality of water purification systems composed of purification materials scattered in appropriate positions in water such as ponds and swamps, and synergizing with the ecosystem function of ponds and swamps. .

Further, since the power of the water turbine and the wind turbine is natural energy, it is possible to purify the water quality in an environment-friendly manner without emitting carbon dioxide unlike the electric energy using fossil fuel. The windmills and waterwheels that have existed since ancient times are familiar to people, and even if they are scattered around a pond or a swamp, they do not disturb the landscape, but rather create a landscape that is more familiar to people.

Further, plants such as aquatic plants, algae, and water moss installed in the water purification system not only adsorb and decompose nitrogen, nitrogen compounds, phosphoric acid, potassium, and organic substances in the raw water, but also by photosynthesis of the plants. It absorbs carbon dioxide and discharges oxygen, and also acts as an air purifier. At its roots, it becomes a habitat for small fish and shrimps, which creates a new food chain.
