Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a water purification device.

(Prior Art) Conventionally, when purifying the water quality of a golf course or other artificial pond, or when trying to prevent the pollution of a water body with a large pollution load, a water purification device B as shown in Fig. 4 has been used. It is used.

This water purification device B includes a pressure water tank 10 and a rapid stirring tank 20.
, a slow stirring tank 30, and a solid-liquid separation tank 40, and the untreated water 50 of the water area C to be purified is placed in the pressure water tank 10.
is pumped up, the untreated water 5o is transferred from the pressure water tank 10 to the rapid stirring tank 2o, and the flocculant 6o is mixed and stirred, and the stirred water containing the flocculant '60 is transferred to the slow stirring tank 30. Furthermore, the water containing the flocculant 60 is transferred from the slow stirring tank 30 to the solid-liquid separation tank 4o to separate the scum 50a and the treated water 50b, and the scum 50a is removed by the scum scraper 7o into the scum storage section. 70a, and the treated water 5
0b was returned to the target water area to purify the water.

(Problems to be Solved by the Invention) However, since the water purification device described above is large-scale, there are problems in that it not only requires a large installation space but also increases cost.

The present invention has been made in view of the above problems, and its purpose is to provide an economical water purification device that does not require a large installation space.

(Means for achieving the object) The water purification device of the present invention for achieving the above object includes:
By providing rotating pipes equipped with water supply holes at the bottom of the water area to be purified so as to be able to rotate freely in a facing manner, and by drilling the water supply holes facing in opposite directions and supplying dissolved oxygen-rich water through the water supply holes. The present invention is characterized in that the turning pipe is turned.

(Function) According to the above configuration, when the dissolved oxygen-rich water is supplied into the polluted water from the water supply holes of the swirl pipe, the water supply holes face in opposite directions, so that the swirl The pipe slowly rotates within the water area to be purified by the water supply power of the rich dissolved oxygen water, and supplies the rich dissolved oxygen water to the bottom of the water and aerates it;
Purify water or prevent the progression of pollution.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Figure 1 shows the water purification device of the present invention installed in an artificial pond! FIG.

Water purification device A is located at the bottom of a golf course or other artificial pond M.
A rotating pipe 1 is rotatably attached to a support pipe 2 protruding from the bottom m, and the rotating pipe 1 rotates so as to be in contact with the bottom m for aeration.

The revolving pipe l is formed to a predetermined length with the end closed with a synthetic resin such as vinyl chloride, and water supply holes 1a are bored at appropriate intervals on the lower surface for supplying dissolved oxygen-rich water W into the polluted water. . A pair of rotary bodies 3 are linearly connected to the rotary body 3 which is rotatably attached to the support tube 2 at a rotary joint.

The water supply hole 1a is bored in the direction opposite to one of the rotating pipes 1 so that the rotating pipe 1 rotates when supplied with the rich dissolved oxygen water W, as shown in (1) and (2) in Fig. 3. There is.

Further, a floating body 1b is attached to the upper surface of the turning pipe 1 to facilitate turning.

Note that this swirl pipe 1 is not limited to a pair as described above,
It is also optional to provide them in a cross shape or radially.

Furthermore, if the turning radius of the swing pipe 1 is to be increased, a turntable should be provided at the center of the swing, or wheels with almost no underwater weight should be attached to the end of the swing pipe 1 to improve stability when turning. You can also do it.

The support pipe 2 supports the swing pipe 1, and is communicated with the swing pipe 1 via the rotating body 3, and has a water supply pipe 4 in the middle.
By connecting the swirl pipe 1, the rich dissolved oxygen water W is
It is intended to supply

Next, how to use this water purification device A will be explained.

First, the swing pipe l is connected from the water supply pipe 4 through the support pipe 2.
When the rich dissolved oxygen water W is supplied to the polluted water, the rich dissolved oxygen water W is supplied into the polluted water through the water supply hole 1a of the swirl pipe 1. Since this water is supplied from the water supply holes 1a facing in opposite directions, the revolving pipe 1 is slowly rotated by the water supply force, and rich dissolved oxygen water W is supplied to the bottom m to oxidize the bottom mud.

(Effects of the Invention) The present invention has the following effects by having the above configuration.

■ Almost all of the water purification equipment is installed submerged in water, so the installation location can be secured easily and reliably, and the scenery is not obstructed.

■ It is economical because the water purification device is operated using extremely little energy.

■ Because the water purification device has a simple structure, it can be easily installed and has fewer failures.

■ The rotation locus of the water supply hole of the revolving pipe draws a large number of dense concentric circles, so dissolved oxygen-rich water spreads throughout the bottom mud, promoting oxidation of the bottom mud.

■ The supply energy of dissolved oxygen-rich water causes moderate disturbance of the bottom mud, promoting the diffusion of oxygen molecules into the bottom mud and promoting oxidation over time.

■ Since the swing span is lightweight underwater, it is possible to install a long span. '■ Since the water purification device is extremely easy to move and disassemble, it can be used as a permanent or mobile device.
