しなければならないという問題点があった。<Problems to be Solved by the Invention> However, in such a water purification method for driving an underwater fan, one end of the underwater fan is locked to a buoy installed on the water surface and an anchor installed on the bottom of the waterway. It has to be held on the surface of the water or in the water by the wire, which interferes with water traffic, and the position of the submersible fan is not stable due to the reaction force during operation, and it is impossible to obtain sufficient water flow generation effect. There was a problem. In addition, the movement of water in the horizontal direction is insufficient only with an underwater fan, the water diffusion area is narrow, and it is considerably large and consumes a large amount of energy in order to obtain sufficient water diffusion and flow velocity. There was a problem that I had to use.

The air sent from the device is discharged to the upstream side (water intake side) or the downstream side (water discharge side) of the drive device,
Generate colloidal air in the released water,
By diffusing this in water, the water is diffused and the flow velocity is increased as compared with the case where only the driving device is used, and the water in the water channel containing the organic sludge is purified by the aeration effect.

必要な量だけ圧送するようになっている。<Embodiment of the Invention> An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a water purification system of the present invention, and FIG. 2 is a sectional view of a water channel which actually adopts this water purification system. In the figure, 1 is a water channel formed between shores 2 and 3, and water flows in this channel 1 in a stagnant state. Reference numeral 4 denotes a drive device installed at a predetermined position at the bottom of the water channel 1. The drive device 4 is composed of an upstream water intake 5, a downstream water discharge port 6, an underwater fan 7, and the like. In addition, if necessary, instead of the submersible fan 7,
Jet type water discharge means can be used. The main body of the drive unit 4 is made of, for example, a concrete block or the like having water passage holes penetrating both ends thereof, or a steel pipe as a main component. Reference numeral 8 denotes a plurality of air supply nozzles as an air discharge device, which are arranged near the front of the water discharge port 6. The air supply nozzle 8 is connected to one end of an air supply pipe 9 laid at a position where it does not interfere with water traffic. The other end of the air supply pipe 9 is connected to an air processing machine 10 such as an air supply pump via a filter device (not shown). The air treatment machine 10 is installed on land (on the shore), and air for aeration is required for the air supply nozzle 8 through the air supply pipe 9 laid in the ground and at the bottom of the water channel 2. It is designed to pump only the amount.
次に、動作について説明する。Next, the operation will be described.
まず、この水質浄化システムを作動するにあたって、上
記駆動装置４の水中ファン７を駆動するとともに、空気
処理機10を作動して、空気を空気供給パイプ９を介して
空気供給ノズル８へ送給する。First, in operating the water purification system, the submersible fan 7 of the drive unit 4 is driven and the air treatment machine 10 is operated to supply air to the air supply nozzle 8 through the air supply pipe 9. .
このため、駆動された水中ファン７は、取水口５側から
駆動装置４の本体内を介して、放水口６へ水路の水を強
制的に送り出し、その放水口６付近に大きな水の流れを
作り、これによって水を水路１の上流側から下流側へ迅
速に流下するのを促進する。For this reason, the driven submersible fan 7 forcibly sends the water in the water channel from the water intake 5 side to the water discharge port 6 through the inside of the main body of the drive device 4, and causes a large flow of water near the water discharge port 6. This facilitates the rapid flow of water from the upstream side of the waterway 1 to the downstream side.
一方、上記空気供給ノズル８に送給された空気は、コロ

および増大するように作用する。従って、潮を干満とと

動交換が促進されるようになる。On the other hand, the air sent to the air supply nozzle 8 becomes colloidal air and is diffused into the water, and this is diffused by receiving the water flow from the driving device 4. Therefore, the arrival area of the air increases in the horizontal direction, and further acts to diffuse and increase this water flow. Therefore, fluid exchange with the water in the outer bay is facilitated with or without tidal tide.

る。<Effects of the Invention> As described above, according to the present invention, since the drive device for horizontally increasing the flow velocity of water in the water channel is provided at the bottom of the water channel, the flow velocity of water does not interfere with water traffic. Can be stably and reliably increased, and the effect of increasing the capacity of the drive device and facilitating its installation can be obtained. Further, since the air discharge device is provided on one or both of the upstream side and the downstream side near the drive device, the diffusion area of the sludge water can be expanded and the flow velocity of the water can be further promoted. As the water exchange becomes more efficient,
Purification of sludge water by aeration is performed, and the effects of increasing the dissolved enzymes and improving the respiratory environment of living organisms can be obtained.
