DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram showing a water purification device according to the present invention. The water purification device of the present invention includes a solar cell 1 for solar power generation, a wind power generation device 2, a diesel power generation device 3, a rectifier 4,
Battery 5, inverter 6, and water wheel (stirring means) 7
1, an air compressor (aeration means) 8, a water purification product 9, and a control unit 11. In addition, in this embodiment, it is used for treating the sewage generated in the housing complex, but it is of course also possible to use it for the purification of clean water in small and medium lakes and reservoirs.

The solar cell 1 is attached to an appropriate place, for example, a portion of the main body of the device where sunlight can be easily received, and the battery 5 and the battery 5 via the rectifier 4A, the switch (normally closed) 10A and the control unit 11. It is connected to the inverter 6. Further, in this solar power generation, since power is not generated at night, the control unit 10A may be configured to automatically perform the connecting / disconnecting operation of the switch 10A. In addition to the above, the solar cell may be installed, for example, at a portion of the wind turbine generator 2 that is likely to receive sunlight, the pillar portion 2B, or the like to save the installation space.

The wind power generator 2 is adapted to perform wind power generation operation within a constant wind speed range day and night.
When the wind speed exceeds a certain level, the blades of the wind turbine are closed to prevent the wind turbine from being damaged. Even in the wind turbine generator 2, the rectifier 4 is used in the same manner as the solar cell.
B, switch (normally closed) 10B and control unit 1
It is connected to the battery 5 and the inverter 6 via 1. Further, if the area where the wind power generator is installed is a place where a constant wind speed constantly blows throughout the year, it is not necessary to particularly perform solar power generation. The wind turbine generator may be a vertical wind turbine generator 2 '(a combination of Darrieus type and Savonius type) as shown in FIG.

The diesel power generator 3 is composed of a diesel engine 3A and a power generator 3B, and is connected to the battery 5 and the inverter 6 via a rectifier 4C, a switch (normally open) 10C and a controller 11. Has been done. The diesel power generator may be directly connected to the air compressor (aeration means) without a rectifier.

Each of the rectifiers 4A to 4C is adapted to convert an alternating current sent from each power generator into a direct current.

The battery 5 is adapted to appropriately charge the battery 2 with electric power supplied from various power generators at any time, and exceeds, for example, the amount of electric power supplied to the motor for the water turbine 7 and the motor for the compressor 8. When such an amount of electric power is generated and the amount of charge in the battery drops below a certain level, surplus electric power is also sent to the battery 5 side,
It is designed to charge.

The inverter 6 converts a direct current into an alternating current in order to supply it to the motor for the water turbine 7 and the motor for the air compressor 8, and is connected to each of these motors.

The water turbine 7 is rotated by a motor (not shown) mounted on a levitation body 7A that floats on the surface of the waste water in the purified water tank 12, and the waste water is constantly mixed to prevent the accumulation of the waste water. At the same time, it is designed to prevent the concentration of the microorganisms (such as bacteria) (such as bacteria that are decomposed into the wastewater) in the wastewater.

The air compressor 8 is equipped with a motor and a blower, and constantly feeds fresh oxygen-containing air into the wastewater through an aeration pipe 8A whose tip extends into the wastewater to supply oxygen to microorganisms such as bacteria. It is like this.

The water purification product 9 directly decomposes the waste,
Or, a natural organism or an inorganic substance that indirectly promotes is used, and in this example, specifically, microorganisms such as bacteria that survive in wastewater or in sludge settled under the wastewater. And soil fungi, plant compounds such as plant phenols (eg, lignin and tannin), and fine stones such as feldspar and quartz are used.
Alternatively, for example, soil fungi taken out from mountain sand or the like may be used. The microorganisms used for this water purification product are not limited to aerobic microorganisms, and, of course, anaerobic microorganisms may be used as long as they decompose filth, but in this case, oxygen is particularly supplied. No air compressor is required because it does not have to be.

Therefore, according to this embodiment, the apparatus is operated by solar power generation or wind power generation, which is clean and requires almost no running cost, except in the case of no wind at night. There is no risk of contaminating.

Next, the water quality water purification method according to the present invention will be described. FIG. 2 shows a water quality water purification apparatus to which the water quality water purification method according to the present invention is applied. In this purified water purification apparatus, the drive mechanism M portion is the drive portion M in the first embodiment (FIG. 1) is used. In addition to this, the water quality inspection unit 13 and the control unit 14 are used.
A pulley driving motor (dropping means) 16 around which the conveyor belt 15 is stretched, and natural purified stones such as vegetable phenol or finely pulverized quartz or feldspar (other than this, for example, taken out from mountain sand or the like) Water purification product of soil bacteria etc.) 17
And a box 18 for expropriating. In addition, although it is used for the water purification of the lake 19 in this embodiment, it may be applied to the water purification in a septic tank such as a river, a farm or an apartment house.

The water quality inspecting means 13 uses an appropriate sensor that chemically detects an appropriate substance to be inspected and converts it into a predetermined signal when the substance exceeds a preset concentration. The output is connected to the input of the control unit 14.
The water quality inspection may be performed by an operator at any time (for example, water is collected at regular intervals and chemically inspected), but in that case, the control unit 14 is particularly necessary. (For example, a timer may be used instead).

When the water quality inspection means 13 detects the deterioration of the water quality, the control section 14 outputs a control signal to the motor 16 and operates for a time corresponding to the degree of contamination.

Therefore, according to this embodiment, in the lake 19 containing the wastewater to be purified, the water purification product 17 made of plant-derived phenol or fine-grained natural purified stone such as quartz or feldspar is added. It can be added at any time when water pollution progresses beyond a certain concentration.

[0023]

As described above, according to the present invention, when purifying purified water or the like, that is, when the purified water is decomposed by using microorganisms such as bacteria, such microorganisms are used. In order to create a good environment for the activities of the above, aeration means and agitation means are provided, and the electric power for operating these drive means is basically generated and supplied by using natural energy. A water purification device with less waste can be provided. Therefore, according to the present invention, there is little environmental damage, there are few restrictions on the place of installation, and no operating cost is required. Therefore, the present invention is particularly suitable for cleaning sewage in an apartment house such as an apartment.

Further, according to the present invention, in purifying purified water, not only microorganisms such as bacteria are used, but other than this, for example, natural stones such as quartz and feldspar, which are finely divided, and lignin and tannin are used. Since it is possible to purify water by actively using water purification products in nature such as plant-derived phenols as a purification means,
A water purification device and a water purification method that are not likely to damage the natural environment can be provided at low cost.
