Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage groove for purifying water which can purify the water flowing through a drainage channel.

[0002]

2. Description of the Related Art Conventionally, polluted wastewater is sent to a treatment plant where it is purified, or its water quality is purified by passing the wastewater from a drainage channel through a separate gravel purification channel. Things are used. That is, sewage water treatment is generally conducted before purification by being guided to a sewage treatment plant from a drainage channel. However, construction of a sewage treatment plant requires a large construction cost and site. Currently, its penetration rate is still low.

[0003] Also, a method of purifying water between gravels and a method of purifying water by forming a biofilm by placing a polyhedron in a water tank has been studied, and in this case, these methods are also applied to a separate site other than the water channel. It is necessary to install sewage facilities and introduce sewage from drainage channels, and this study essentially has the problem that a separate site is required for the facilities as described above. According to this, there is a problem that sludge or the like accumulates after a certain period between purification bodies, for example, gravel, and it becomes necessary to perform back washing, and the back washing has to be performed artificially.

[0004]

SUMMARY OF THE INVENTION According to the present invention, water purified by installing various types of water purifiers in a drainage ditch is used as it is without providing a separate treatment facility for purifying wastewater. Provided is a water purification purifying drain which can be discharged and can economically purify water without performing backwashing.

[0005]

SUMMARY OF THE INVENTION A drainage groove for water purification according to the present invention has a depth greater than the depth of a normal U-shaped drainage groove, and has sedimentation pits at the bottom at appropriate intervals. In the deep U-shaped drain, the appropriate height and width slightly smaller than the inner width,
A rectangular hollow lattice-shaped box-shaped framework having an appropriate length is installed internally so that it can be locked, and a buoyant water purification body is installed in the hollow portion of the box-shaped framework, and on the upper surface thereof. It consists of a drain for water purification with a float body, and furthermore,
As a water purification body, a biofilm body in which a large number of fiber strings are arranged in the vertical direction, a floating polyhedral sphere formed by intersecting a circular strip of appropriate width and thickness vertically and horizontally, or a cylindrical body Floating body polyhedral cylindrical body formed by covering both ends of a pipe with a circular band of appropriate width and thickness at right angles to the surface of the pipe and separating the space with a plate at appropriate intervals In some cases, the deep U-shaped drainage groove is formed of a water purification purifying drainage formed of porous permeable concrete.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a drainage gutter for water purification according to an embodiment of the present invention; FIG. FIG. 3 is a side sectional view showing a use state at the time of flooding, and FIG. 2 is an enlarged front sectional view of FIG.
FIG. 4 is an enlarged front sectional view of FIG.

First, the water purification purifying drain has a depth U which is approximately twice as deep as a normal U-shaped drain, and is provided at the bottom in the length direction as appropriate. The sedimentation basins 2 are provided at intervals L (for example, 5 m to 10 m). Next, half of the depth, that is, H
1 and 2, a rectangular hollow lattice-shaped box-shaped framework 3 having a height of H / 2, a width slightly smaller than its inner width, and an appropriate length A (for example, A = L-several meters) is shown in FIGS. It is internally provided so as to be locked by a moist chain or the like indicated by reference numeral 4.

The lattice-shaped box-shaped framework 3 is formed by lining an appropriate mesh 7 inside the lattice-shaped frame 3 or by using a suitable material such as a perforated plate having an infinite number of appropriate holes in a hollow lattice shape. It shall be. Next, a buoyant water purification body, for example, a pumice 5 as in this embodiment of FIG. 1 is provided in the hollow portion of the box-shaped framework 3 and a float body 6 (for example, (Hollow body or foam).

The deep U-shaped drain 1 having the above structure
Is covered with an outer lid 8. In the water purification purifying drain of the present invention having the above-described configuration, the box-shaped framework 3 is used in the case of the flat water shown in FIG.
Since there is not enough water to float as a whole, the wastewater is purified while purifying the water quality while flowing through the gap in the pumice 5 of the water purification body. However, at the time of flooding as shown in FIG. Since the water purification body such as the box-shaped framework 3 and the pumice stone 5 also rises to a position above the U-shaped drain ditch 1, the lower half section does not hinder the expected drainage amount.

Further, at the time of flooding, fine sediment accumulated between the water purification bodies such as the bottom of the deep U-shaped drainage channel 1 and individual pumice stones 5 at the time of flat water can be washed naturally. It can be settled in the basin 2 and removed separately as appropriate. In the above embodiment, the pumice stone 5 is provided inside the hollow portion of the box-shaped framework 3 as a water purification body. However, as shown in FIG. This is a water purification body formed by a plurality of biofilms arranged at intervals, and exerts the same function as that of FIG.

Further, as shown in FIG. 6, as shown in the side view of FIG. 7 and the bird's-eye view of FIG. 8, a floating body multifaceted by forming circular strips of appropriate width and thickness to intersect vertically and horizontally. The spherical body 11 is provided inside the net 7 in the box-shaped framework 3, and the float body 6 is provided on the upper surface thereof, which is used for water purification.

Further, as shown in FIG. 9, as shown in the side view of FIG. 10 and the bird's-eye view of FIG. 11, both ends of a hollow pipe are covered, and an appropriate width is set at right angles to the surface of the pipe. A circular band-like body having a thickness is adhered, and a floating polyhedral cylindrical body 12 that is formed by dividing the space by a plate-like body at an appropriate interval and floats entirely in water is provided inside the box-shaped framework 3. This is an example in which a water purification body is used, and has a structure in which the water purification body can be rotated.

Next, FIG. 12 shows the depth U described in FIG.
The drainage ditches for water purification according to the present invention, which are composed of the
FIG. 6 is a front sectional view showing an application example of burying in the riverbed 14 of No. 3 and introducing water of the river 13 to purify the water.

Further, FIG. 13 shows that when the contaminated settlement drainage or the like is discharged into the river 13 or the like through the gutter pipe 16 in the embankment 15, the deep U-shaped drainage groove 1 of the water purification purifying drain of the present invention is made porous. This is an application example in which the deep U-shaped drain ditch 1 is formed along the embankment 15 by being formed of permeable concrete. It flows down under the ground, passes through the gravel and sand layer 17 in the riverbed 14,
The water is secondarily purified and joins the water of the river 13.

[0015]

The use of the water purification purifying drain according to the present invention described above enables the water purification function to be exhibited and accumulated in the deep U-shaped drain provided on the site of the currently used drain. The backwash of the sludge can be naturally performed at the time of flooding, and the wastewater can be economically purified without separately providing a wastewater treatment facility.
