Abstract

PURPOSE:To effectively withdraw a suspended matter, and to remove a pollutant particle in a river by wiring a anti-pollution film on both sides of the window part of the river in a dam, lakes and marshes, and in a sea, in multiple, with almost the width of the river left. CONSTITUTION:On both sides of an inflow part 2 into which a river 1 of lake or sea, etc., flow, with the width of the river 1 left, an anti-pollution film 3 composed of a float 6, a sheet or mesh trailing film 5 is wired at a certain interval with one another, in multiple. By wiring the anti-pollution film 3 in a circular arc, effectiveness is improved. When the water of the river 1 flows into the sea and so on, a Karman's vortex and a labyrinth flow 4 are generated at the anti-pollution films on both sides. A suspended matter can be captured thereby even if the flow or flow velocity of the river 1 changes, and a particulate pollutant material in the river water is settled, whereby the river 1 is purified.

Description

[Detailed description of the invention] The present invention relates to a method for purifying rivers flowing into rivers, oceans, etc.

With the development of industry, rivers in various places have become polluted due to the flow of various types of wastewater and illegal dumping of various types of garbage.

In recent years, various methods have been proposed to improve these situations, but all have advantages and disadvantages, and no satisfactory method has yet been found.

The present inventor has completed the present invention as a result of various studies aimed at solving these conventional drawbacks.

That is, the present invention relates to a method for purifying a river at an inlet of a river, such as a lake or the sea, which is characterized by leaving approximately the width of the river at the inlet of the river and extending multiple anti-pollution films on both sides of the inlet.

Next, the method of the present invention will be explained with reference to the drawings, but the present invention is not limited to the following explanation.

Figure 1 is a situation diagram showing the parts where a river flows into the subway, the sea, etc., where 1 is the river, 2 is the inflow part of the river, and 3
is a multilayer anti-pollution membrane.

FIG. 2 is a further enlarged view of FIG. 1, showing the state of river inflow. In other words, when water from a river flows into the sea, etc., since there are multiple pollution prevention membranes on both sides of the river, Karman vortices and Laberins flows 4 are generated in the pollution prevention membranes, which causes the river to flow into the sea. Even if the flow rate and speed of the river changes, it captures suspended matter and settles fine particulate pollutants in the river water, cleaning the river for the same month.

According to the method of the present invention, since floating objects in rivers, etc. often flow along the banks of rivers, it is possible to effectively collect these floating objects and also remove pollutant particles in rivers as described above. can do.

The anti-fouling membrane used in the method of the present invention is, for example, composed of a hanging membrane 5 and a float 6 as shown in FIG.

FIG. 4 is a side view of FIG. 3, showing one set of two strips of hanging M5. FIG. 5 shows a plan view of FIG. 3, and by fixing the float 7 to a machete and forming the so-called float into a ladder shape, a two-line anti-fouling membrane can be constructed. reactor. If such anti-pollution membranes are spread in multiple layers at intervals of, for example, 10 to 20 mm, and a board or the like is laid on top of the ladder-type float, a floating pier can be created, making it possible to moor boats, etc. .

Furthermore, in the method of the present invention, it is preferable to spread the pollution prevention M8 in a mold on each multi-spread pollution prevention film as shown in FIG. 6, because the trapped floating matter can be collected when it is relatively fixed. .

The effect of the method of spreading the pollution prevention film in the method of the present invention can be further improved by spreading it in an arc shape as shown in FIG. Also, a pollution prevention membrane may be hung on a newly constructed floating pier.

The hanging membrane 5 used in the present invention can be in various forms such as a sheet shape, a perforated sheet shape, a net shape, and a slat shape.

As mentioned above, according to the method of the present invention, ships navigating from rivers to the sea can pass freely, and suspended matter and pollutants from rivers can be removed from many surfaces, so river purification is extremely effective. Be able to do this.

[Brief explanation of drawings]

Fig. 1 is a state diagram showing the case where a pollution prevention membrane is extended at the inflow part of a river, Fig. 2 is an enlarged state diagram of the river inflow part of Fig. 1, and Fig. 3 is an example of the pollution prevention film. FIG. 4 is a side view of FIG. 3, FIG. 5 is a plan view of FIG. 3, and FIGS. 6 and 7 are views of other pollution prevention films of the present invention. It is a state diagram of the river inflow part showing the expansion method.
