Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention purifies polluted swamps and closed water bodies such as river stagnation by using the sewage purifying action of reeds, and prevents the occurrence of blue-green algae based on eutrophication. In addition, the present invention relates to planting for water purification, which is used for allowing microorganisms to inhabit and aquatic organisms such as fish and shellfish to proliferate.

[0002]

2. Description of the Related Art In recent years, revetment works have been widely carried out to prevent storm and flood damage, and safety from storm and flood damage has been maintained. As a result, the purification function of water quality is also lost, and the pollution of water quality in closed water areas in particular progresses. ing.

In order to solve this problem, various proposals for purifying water quality and improving the landscape have been made. For example, a method of planting willows in wetlands to achieve greening, a method of planting river willows, shoves, etc. directly in water to create forests in shallow water ahead of the shoreline, a raft with a low specific gravity such as styrene foam A floating island method is known in which a container filled with soil is attached, and herbs such as willow, iris, and shrub are planted.

[Problems to be solved by the invention]

[0004] However, the above-mentioned conventional method has many problems and has not been widely used. For example, the method of planting willows in the above-mentioned wetlands is based on drought during the growing season in lakeside wetlands, etc., and when the water level falls, the upper germinated and elongated roots of the stem in the full season are exposed to the top and die. Problem.

[0005] The method of planting herbs such as irises and shoves directly in water is extensive and requires a great deal of labor and cost to plant these herbs on the waterside. In addition, these herbs die in the fall. In order to eutrophize the water quality by falling down and decaying in the water, it is necessary to go to the waterside every year at the end of these growths and perform reaping work on a poor scaffold, and the labor of a strong young man There is a problem that it is necessary and that the cost is high.

On the other hand, the floating island method of planting willows, irises, and shoves cannot purify water in soil filled in a container such as polystyrene foam attached to a raft, so that water purification cannot be expected. As a result, fine segregated substances are gradually released by the action of wind, rain and waves, which may become garbage on the water, deteriorating the surrounding environment, and damaging the landscape.

An object of the present invention is to solve the above-mentioned problems by purifying polluted swamps and stagnation of rivers by using reed sewage purifying action of reeds. It is an object of the present invention to provide a plant for water purification that is used to prevent the occurrence of algae based on nutrients, to inhabit microorganisms, and to allow aquatic organisms such as fish and shellfish to propagate.

The present inventor has found that reeds are plants having extremely high sewage purification ability, and that the reeds can grow while elongating their roots under conditions that can be called hydroponic cultivation.
In a location separate from lakes and rivers, that is, in factories, filling containers with fillings, planting reeds and fixing them in fillings, creating plantings, transporting them to their destinations, The present invention has been completed by obtaining a plant for water purification, which is simple and has a very high sewage purification ability that only requires floating.

[Means for Solving the Problems]

[0009] That is, the present invention provides a plant for purifying water by filling a charcoal into a container having an open top structure and having an opening on a wall surface or a bottom surface or both, and installing reed roots on the charcoal. Is provided.

BEST MODE FOR CARRYING OUT THE INVENTION

[0010] The container is filled with charcoal as an essential component, and the charcoal used is preferably carbonized coniferous wood. As the filling material for the container, in addition to charcoal, those usually used for planting are used.

One method of obtaining a plant for purifying water according to the present invention is to insert a charcoal rod into a container having an opening on a wall surface or a bottom surface or both,
Next, lump charcoal is put in the gap between the rod-shaped charcoal, and then granular charcoal is charged. Needless to say, only lump charcoal, only granular charcoal, bar charcoal, or other filler may be used. Put the reed roots there. It may have stems or just roots. A preferred method is to take reeds, cut the stalks, wash with water to remove mud, and bury them in charcoal. From there, lump charcoal, granular charcoal, powdery charcoal, or the like is appropriately put, and if necessary, the container is immersed in water using a filler other than charcoal, such as soil, and allowed to stand. Fertilization may or may not be applied. Therefore, in the present invention, planting reeds may have stems or only roots, but it is necessary to plant reed roots. If the reed roots are kept in the water in the above way, they will take root and the charcoal will take root inside. As described above, the container used in the present invention has a shape as shown in FIGS. 1, 3, and 4 that is easy to use and is conveniently formed of resin, but may be a basket. It may be a container made of timber, or a net. In any case, any material can be used as long as it is open at the top and can store a combination of bar-shaped charcoal, bar-shaped charcoal, granular charcoal, and powdered charcoal.

The plant for purifying water according to the present invention can be used while standing in water. However, a frame made of timber or, preferably, a frame of an aluminum pipe on the surface of anodized aluminum is formed into a floating body. It is preferable that the water-purifying plant be installed so as to be slightly lower than the water surface. The water purification plant according to the present invention suspended on the floating body may be moored with an anchor, or may be connected to the shore with a rope if it is near the shore. When installed in this manner, the roots grow and shoot in 3 to 4 months, and the plant for water purification according to the present invention starts to exhibit its function.

When charcoal is used as a filler, the growth of reed roots is convenient, and when coniferous charcoal is used as a filler, the reed roots are fully developed in a short period of time, buds appear, and so-called reeds are formed. Become.
As the charcoal used in the present invention, any charcoal obtained by burning wood to charcoal can be used. Those obtained by carbonizing coniferous bamboo such as cedar and cypress are preferable. These have provisional conduits and have the property that reeds can easily spread their roots. Bincho charcoal, which is baked at 1200 ° C or higher, can also be used.

The present invention will be described more specifically with reference to the drawings. FIG. 1 is a perspective view of a container according to the present invention. This container 1 has a large number of openings 2 from the wall surface to the bottom surface.
Is provided. Further, in order to fix the container 1 to the floating body 7, the holes 3 for fitting into the container fixing projections 8 are provided.
Are provided in the container 1. FIG. 3 is a perspective view of another example of the container according to the present invention. Thus, the wall surface may be entirely open. Further, as shown in FIG. 4, the containers may be continuous.

FIG. 2 is a perspective view of a container 1 filled with charcoal, planted with reed roots, and kept in water so that the upper surface thereof is slightly below the water surface, and after 4 months. The roots of the reeds 5 are rooted on charcoal, and reed buds emerge from the floor 4 and grow on grass. The container 1 has a floating body 7 as shown in FIG.
It is set as shown in the side view. Figure 2 shows each container

The plant for water purification according to the present invention can be produced in a factory and can be easily transported.
Even in closed water areas in town, where water depth is large and aquatic plants do not grow, or where aquatic plants do not grow due to revetment work, it can be easily installed and water can be easily purified. In the fall, when the reeds die, if they are burned as they are, they will come out of the water and the dead reeds will burn. Grows, and is effective as a plant for water purification.

In the purification of water quality, charcoal alone has a certain degree of water purification action. However, in water areas where blue water is generated,
Eyes close and lose their effect immediately. However, in the plant for water purification according to the present invention, the purifying action of reeds and the purifying action of charcoal act synergistically, and it is presumed that the reeds prevent bud clogging of charcoal, but the effect remains. Even in a closed water area where there is blue-green algae and foul odor, blue-green algae disappear and the water is purified.

In the plant for water purification according to the present invention, when the containers are placed apart from each other as shown in FIG. 6, small fish are buried there, and small fish are hidden from large ferocious fish such as a black bath. By moving the plant for water purification, the water in the plant for water purification can be forcibly exchanged, and the purification action can be effectively promoted. Small fish can also enter and exit the container from the trench 2 of the container 1, eat microbes and plankton near the roots of reeds, and also eliminate skin diseases, fungi, and white mold from here. Can be.

In the plant for water purification according to the present invention, reeds grow in summer, and as a result, it is possible to prevent a rise in temperature in a closed water area.
