Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for treating road drainage, and more particularly to a device for treating road drainage constructed in a drainage system from an elevated portion of an expressway or an ordinary road.

[0002]

2. Description of the Related Art On a highway or the like, a large amount of exhaust gas is emitted from a traveling vehicle and these exhaust gases float in the space on the road or float in the surrounding space beyond the road. In particular, in rainy weather, the components contained in these gases are taken into rainwater and flow out of the road through a drainage system. The components contained in the exhaust gas include particulate matter (PM) and nitrogen oxides (NO _x ) from diesel vehicles, and these harmful substances are directly contained in the soil of roadside trees along the road. It becomes a factor that impedes the growth of street trees and a factor that pollutes the environment, as it is soaked in water and has an adverse effect, and flows out into rivers and the sea through drains.

[0003]

SUMMARY OF THE INVENTION In view of these matters,
Various methods have been proposed to try to achieve purification of exhaust gas by improving the exhaust gas outflow system on the vehicle side and the engine injection system, etc., but it is the current situation that it has not been widely implemented in practice and has not been effective. .

In view of the above situation, the present inventor takes an effective measure by changing the way of thinking and taking improvement measures on the road side for the improvement measures on the vehicle side which are slow in achievement speed and costly. The inventors have found out what can be done and have completed the present invention.

The present invention has been made to solve the above problems, and its purpose is to solve the pollution problem by effectively purifying harmful substances flowing out from the road in rainy weather with an inexpensive system. It is to provide a road drainage treatment device capable of processing.

[0006]

The above objects can be achieved by the inventions described in the claims. That is, the characteristic configuration of the road wastewater treatment apparatus according to the present invention is that a harmful substance purification material is provided in the middle of the drainage system from various roads including highways and general roads.

According to this structure, since the harmful substance purification material is provided in the drainage system from various roads including highways and general roads, the particulate matter (P
When harmful substances such as M) and nitrogen oxides (NO _x ) are mixed with rainwater and discharged outside the road, they will be collected by this purification material, cleaned and released. There is no danger of toxic substances flowing out into the soil where trees are planted or into rivers and the sea. Therefore, it is possible to prevent the harmful substances from being discharged to the outside of the road without waiting for costly improvement on the vehicle side. Note that the purifying material corresponds to various substances that do not adsorb and discharge harmful substances.

As a result, it is possible to provide a road drainage treatment device capable of solving the pollution problem by effectively purifying the harmful substances flowing out of the road in rainy weather by an inexpensive system.

The harmful substance purification material preferably has weathered reef-building corals.

According to this structure, the toxic substance purification material can be provided in large quantities and at low cost by specifying it as a weathered reef coral (produced in large quantities in Okinawa Prefecture, etc., also called coral sand). The coral makes the wastewater purification process extremely effective and harmless. The weathered reef coral has a fine porous property and is excellent in adsorbability for various fine particles and oil components in exhaust gas, which is convenient. Not only that, the weathered reefs that have been used and removed can be reused as soil pollution purification materials by laying them on the bottom of rivers or walls, and the coral minerals obtained through weathered reefs. If water is temporarily stored in a water tank and used for spraying on roadside trees, etc., it promotes the growth of plants, and if these mineral water is supplied to a negative ion generator installed around intersections, etc. It is also possible to generate and supply a large amount.

As a result, the wastewater purification treatment can be more effectively and sufficiently exerted by utilizing the weathered reef-building corals obtained from the natural world in large quantities and at low cost.

The harmful substance purification material is preferably formed as a cartridge.

According to this structure, it is easy to attach and detach, and it is convenient because it can be easily attached and replaced in the middle of the drainage system from various roads. It should be noted that it is more preferable to store the harmful substance purification material in the cartridge in the form of a honeycomb because the adsorption effect is enhanced.

It is preferable that the harmful substance purification material is mounted in the middle of a pipe extending from a road.

It is convenient to install a toxic substance purification material in the middle of a pipe extending from a highway or the like installed higher than an ordinary road because rainwater contaminated during the fall can be promptly purified. Good, and also when discharged from a road on the ground to the outside of the road, it is convenient to ensure the flow path of purified water.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a portion where the upper and lower lines of an elevated expressway are provided side by side. This expressway is configured by arranging a road stand 2 on an upright pedestal 1 and laying a road surface layer 3 on the road stand 2.

The roadbed 2 and the road surface layer 3 on the road on the right side in the drawing incline to the right by a few degrees, and the road on the left side in the drawing inclines in the opposite direction. A road drainage groove 4 is formed in a direction orthogonal to each other.
A water collecting treatment section 5 is formed on the opposite side of the drainage groove 4, and a drain pipe (trough) 6 which is a pipe is hung from the water collecting treatment section 5.

In the middle of each drain pipe 6, a cartridge 8 formed by containing powdered weathered reef-building coral is installed as shown in FIG. That is, the diameter of the drainage pipe 6 is set to a large-diameter portion 9 and an inspection window 10 is opened in the half-circumference thereof. 1
It is possible to open and close with one touch by 3.
A cartridge 8 having a tapered peripheral surface 8a at the lower end is dropped into the above-mentioned structure so that the cartridge 8 can be set. In this case, the tapered surface 8a is supported by the inner peripheral tapered surface 9a at the lower end of the large diameter portion 9 so as to be upright and concentric. By removing the lock 13 and opening the closing lid 11, the inside cartridge 8 can be seen through the inspection window 10, and the cartridge 8 can be grasped and taken out, or a new one can be replaced and set freely. There is. The cartridge 8 is formed in a honeycomb shape as viewed from above in FIG. 2, and has weathered reef-building corals mixed in the honeycomb wall. The honeycomb itself can be formed of non-woven fabric or the like. However, the shape of the cartridge 8 is not particularly limited, and may be such that the weathered reef coral is wrapped in a mesh or the like, and various shapes can be used as long as it can be stored in the drainage pipe 6. .

As shown in FIG. 1, a water receiving tank 16 is installed on the base 15 below the drain pipe 6, and the water receiving tank 16 is provided.
While the water is communicated with the drainage pipe 6, a cartridge 8 also having a honeycomb shape is placed in the water receiving tank 16, and the outlet pipe 17 is provided from the lower part of the water receiving tank 16.

In this case, it is desirable that the cartridge 8 be mounted in the lowest position as much as possible because it is easy to attach and detach. It should be noted that the cartridge 8 can be replaced by an open / close type water receiving tank 16 as shown in FIG. 2, or as shown in FIG. 1 (right side road), the cartridge 8 can be connected in series to form an opening / closing lid 19. When the handle 20 is opened, the puller 20 may be allowed to move in and out.

[Other Embodiments] (1) The water receiving tank may be configured as shown in FIG. In the embodiment shown in FIG. 3, a large-capacity water storage tank 22 is installed in communication with the drainage pipe 6. Since the water storage tank 22 temporarily stores the wastewater, the wastewater is purified by the weathered reef coral cartridge 8 in a sufficient time. At the same time, the wastewater is alkalized and subdivided as the minerals from the weathered reef coral elute, and the eluted minerals such as calcium, magnesium, and potassium are sprinkled by, for example, watering with a water conduit hose 25 equipped with a nozzle 24. The growth of trees such as roadside trees will be activated through soil modification. in this case,
The water from the water storage tank 22 can be sprinkled by water pressure, but a pump can be attached to enable forced injection. The replacement method of the cartridge 8 is as shown in FIG.
In addition to the opening / closing method through the opening / closing lid 19 described above, it is also possible to adopt a method in which the upper lid 26 provided in the storage tank 22 is opened so that it can be freely moved in and out through the stair steps. The upper lid 26 is not always necessary, and the upper portion of the storage tank 22 may be an open type at all times.

If purified water is sent as coral mineral water to, for example, a negative ion generator installed outdoors such as at an intersection or indoors, a large amount of negative ions are generated under ultrasonic vibration. -It will be effectively used to supply it. The weathered reefs that have these effects are extremely useful in that they are provided in large quantities at extremely low cost from the natural world such as the southern tip of Okinawa and are harmless.
