A discharge pipe 22 communicating with 4 and 15 is a control panel for controlling electric equipment such as the pump 2, the blower 5, and the solenoid valves 9 to 12. The microorganism culture layer 7 is composed of an adherent and microorganisms attached to the adherend. Examples of the adhering body include zeolite, charcoal, bamboo charcoal, and vermiculite, which are present in nature, and chemically produced PVC-based, poly-based plastic, small containers for lactic acid beverages, plastic bottles, styrofoam, and the like. . The microorganisms attached to the adherent are aerobic microorganisms and facultative anaerobic microorganisms.

The operation of the water purification apparatus configured as described above will be described. The operation usually consists of a circulation operation and a cleaning operation. First, the normal circulation operation will be described.

An aerobic microorganism and a facultative anaerobic microorganism are present in the pond 1, and an aerobic microorganism and a facultative anaerobic microorganism are also present in the microorganism culture layer 7 in the water purification tank 6. These are attached to the above-mentioned attached body. When a bottle is used as an attachment, it is necessary to make a hole in the bottom so that water can pass through. In the case of a bottle-shaped adherend, aerobic microorganisms adhere to the outer peripheral surface, and facultative anaerobic microorganisms adhere to the inner peripheral surface. Pond 1 water contains bacteria, blue-green algae,
It contains organic matter such as plankton and scale (oxide film on the metal surface), and is unsuitable for use as agricultural water, water for breeding fish and shellfish, and drinking water for humans and livestock. At the beginning of the installation of the water purification device according to the present embodiment, the pond 1
Is generally considered to be in the state described above.

The water in the pond 1 is first absorbed by the pump 2 via the water inlet 3 and is discharged from the pump 2 to the magnetic water treatment unit 4. The water discharged to the magnetic water treatment unit 4 has its hydrogen bonds broken by the magnetic field in the magnetic water treatment unit 4 and becomes water composed of small clusters, that is, water that has been magnetized. By becoming magnetized water, water purification in the water purification tank 6 described later is promoted.

The blower 5 mixes the water discharged from the magnetic water treatment section 4 with air. For example, a volume 45 of air is mixed with a volume 55 of water. This air mixing promotes water purification by microorganisms described below. Water purification tank 6
The solenoid valves 9, 11 and the solenoid valves 10, 12 are disposed on the inlet side and the outlet side of the solenoid valve. In a normal circulation state, the inlet side solenoid valve 9 and the outlet side solenoid valve 10 are open, and the inlet side solenoid valve 11 and the outlet side solenoid valve 12 are controlled to be closed, and the water into which the air is mixed is injected from below the water purification tank 6,
As the time elapses, the water surface moves upward, and eventually reaches the position of the outlet side solenoid valve 10, that is, the position of the return pipe 14. That is, the contaminated water moves from the bottom to the top in the microbial culture layer 7 of the water purification tank 6, and returns to the pond 1 from the return port 16 via the solenoid valve 10, the return pipe 14, and the discharge pipe 16a. The water returned to the pond 1 is also absorbed from the water inlet 3 by the pump 2. The contaminated water moves from the bottom to the top in the microbial culture layer 7 in 60 seconds to 80 seconds, whereby the organic matter contained in the water is treated by the microorganisms, and the scale changes to a state in which the scale is easily treated, for example, a slurry. .

By continuously performing the normal circulation operation as described above, the water in the pond 1 circulates through the water purification device and is gradually activated and purified. Such water becomes delicious water when used as drinking water, and does not form scale even when used for piping. The water treatment capacity in the normal circulation operation is such that the pond 1 is emptied in 3 to 5 days when the treated water is not returned to the pond 1.

The cleaning operation is performed when it is detected that an organic substance or scale is excessively adhered to the adhered body. This is for recovering the purifying action by discharging the organic substances and the like attached to the adherends of the microorganism culture layer 7 to the pond 1. However, the microorganisms are returned to the pond 1 together with the organic substances and someday, the microorganisms are re-used. Therefore, there is no need to replenish new microorganisms, and there is no need for operations such as microbial exchange.

In the cleaning operation, the inlet-side solenoid valve 11 and the outlet-side solenoid valve 12 are controlled to be in an open state, and the inlet-side solenoid valve 9 and the outlet-side solenoid valve 10 are controlled to be in a closed state.

5. Return to the pond 1 from the return port 17 via the discharge pipe 17a. That is, the water injected into the water purification tank 6 flows down the microorganism culture layer 7 from above to below as high-speed flowing water. Thereby, the organic substances and the like adhering to the adhering body can be washed away, and the purification ability can be enhanced. The cleaning operation is
At first, the water in the pond 1 is also polluted, and the organic matter and the like easily adhere to the adhered body, so that it is considered that the water purification is frequently performed.

In this embodiment, the filter is not described at all. However, for example, a filter may be attached to the water inlet 3 to first filter the water and then discharge the water from the pump 2.

As described above, according to the present embodiment, the water in the pond 1 is circulated through the water purification device by continuously performing the normal circulation operation, so that the water in the pond 1 is gradually activated. And can be purified. In addition, since the washing operation is performed by changing the flow path in the water purification tank 6 as necessary, it is possible to remove organic substances and the like adhering to the adhering body and enhance the water purification ability. In this washing operation, the microorganisms are returned to the pond 1 again, so that an operation such as replenishment of new microorganisms is not required.
