DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contaminated water purification pile for purifying contaminated water in lakes, rivers, oceans or the ground.

[0002]

2. Description of the Related Art Conventionally, as a method for enhancing the natural purification power of river water, for example, there is a method described in Japanese Patent Application Laid-Open No. 6-248625. This method of enhancing the natural purification of river water is based on soil,
By embedding a tubular material filled with a filler consisting of sand, stone, shells, activated carbon or a mixture thereof, into a riverbed or embankment with a part of its tip protruding into the water by a suitable length into the water An attempt was made to artificially disturb the water flow of a river, thereby preventing the accumulation of sediment on the riverbed or the water-contacting portion, thereby enhancing the natural purification power of the river.

[0003]

However, in order to purify a river with the above-mentioned tubular material, a certain amount of water flow must be provided. Therefore, in places where there is no water flow, such as near the shore of a river or in a lake or marsh, there is a need for natural purification. It cannot be strengthened.

Further, any filler made of soil, sand, stone, shells, activated carbon or a mixture thereof can filter impurities in water, but has no function of decomposing organic substances as pollutants. Further, when these tubular members are arranged near the shore, the landscape is easily damaged.

Accordingly, the present invention is capable of purifying contaminated water from lakes, marshes, rivers, etc., regardless of the presence or absence of water flow, as well as functioning as a pile for revetment, water control, and the like, and does not impair the landscape. It is intended to provide a contaminated water purification pile.

[0006]

A contaminated water purification pile according to the present invention has a pile main body 5 made of metal having a bottomed cylindrical shape equipped with a lid 6 for opening and closing an upper end opening 5e. A purifying material mounting plate 5b made of a wire mesh or the like is provided at a required position in the main body 5 according to the depth of a lake, a river, or the like.
The purifying material 2 to which the microorganisms for purifying the contaminated water is attached is placed on the purifying material placing plate 5b, and a plurality of transparent materials are provided only on the peripheral wall 5c of the pile body 5 facing the purifying material 2. Hole 5d
Are formed over the entire circumference.

The microorganisms in the pile body 5 gradually decompose the pollutants such as organic substances contained in the contaminated water around the pile body 5 while going in and out of the pile body 5 through the through holes 5d. To purify.

[0008]

Embodiments of the present invention will be described with reference to the drawings. B is a contaminated water purification pile according to the present invention, which houses a purification material 2 in a bottomed cylindrical pile body 5 having an open upper end and a bottom plate 5a fixed to the lower end, as shown in FIG. It is made.

The pile body 5 is made of a known metal, and is formed slightly longer depending on the depth of a lake, a river, or the like where the pile body 5 is to be installed.

In the pile main body 5, a wire mesh 5b, which is a purifying material mounting plate on which the purifying material 2 is mounted, is disposed at a required position near the water surface or near the water bottom, and the peripheral wall 5c has a purifying material. A plurality of through-holes 5d are formed in a predetermined pattern such as a grid pattern, a staggered pattern, etc. over the entire circumference only in a portion facing the material 2. Reference numeral 6 denotes a lid for opening and closing the upper end opening 5e of the pile main body 5 so that the purifying material 2 and microorganisms can be put into the pile main body 5.

As the purifying material 2, it is preferable to use a material capable of easily propagating microorganisms described below and adsorbing pollutants such as organic substances contained in contaminated water.
Specifically, in addition to fibers such as polyvinylidene chloride, polypropylene, and vinylon, for example, non-woven fabric, activated carbon, charcoal,
Gravel, algae, aquatic plants and the like may be used. In any case, the surface area should be increased so that microorganisms can be easily attached.

Microorganisms decompose pollutants such as organic substances contained in contaminated water, and are, for example, aerobic or anaerobic, and these can be used as appropriate according to the environment. The aerobic thing is made to adhere to.

As shown in FIG. 2, the contaminated water purification pile B is a known glue with a bottom plate 5a grounded on a water bottom 4a in order to revet a bank 4 along a shore such as a lake or a river. It is mixed and installed side by side for each required number between fastening piles (not shown). In addition, you may make it use only the contaminated water purification pile B, without mixing with a well-known gluing pile.

On the shores of lakes, marshes, rivers, etc.,
The microorganisms adhering to the purifying material 2 enter and exit the inside and outside of the pile body 5 through the through holes 5d of the contaminated water purification pile B,
It gradually decomposes polluting substances such as organic substances contained in surrounding contaminated water, thereby purifying the contaminated water. Further, the polluting substance is also adsorbed by the purifying material 2, and contaminated water can be purified by the adsorbing action.

The present invention can be modified as follows. In the above description, an example of purifying contaminated water from a lake, a river, or the like has been described. However, the contaminated water purification pile may be buried in the soil to a required depth to purify groundwater.

Although the contaminated water purification pile has been described as one for revetment of lakes, marshes and rivers, it can be used as a pile for water control, for example. Further, it may be used as a pier of a pier, a eight bridge, or the like.

Further, in the pile main body, the same purifying material mounting plate as the above-mentioned purifying material mounting plate is formed in multiple stages at required intervals, and the purifying material is mounted on each of the purifying material mounting plates. It may be structured.

Furthermore, as the above-mentioned contaminated water purification pile, a bottom plate formed flat is exemplified, but the bottom plate may be made to project downward in a conical shape.

[0019]

According to the first and second aspects of the present invention, the pile main body is made of metal having a bottomed cylindrical shape equipped with a lid for opening and closing the upper end opening. At the required position according to the water depth of rivers, etc., a purifying material mounting plate made of wire mesh etc. is arranged, and on the purifying material mounting plate, a purifying material with microorganisms that purify contaminated water is mounted. In addition, a plurality of through-holes are formed only on the peripheral wall of the pile body facing the purification material, so lakes, rivers, rivers, etc. A purifying function can be added, so that it is not necessary to provide a facility for purifying contaminated water separately from the piles, so that construction costs can be reduced and the scenery is not impaired.

In addition, since microorganisms adhering to the purifying material enter and exit the pile body to decompose the polluting substance contained in the contaminated water, it is possible to purify the contaminated water regardless of the presence or absence of a water flow. it can.

Since the purifying material is formed of a material that adsorbs the pollutant causing substances such as organic substances contained in the contaminated water, the purifying material itself can also adsorb the pollutant causing substances and contribute to the purification of the contaminated water.

Since a plurality of through holes are formed only on the peripheral wall of the pile main body facing the purifying material, microorganisms can easily enter and exit.

Since the lid for opening and closing the pile body is attached to the upper end opening of the pile body, it is possible to easily insert and replace the purifying material into the pile body, or insert and replace microorganisms.

According to the second aspect of the present invention, in addition to the above-mentioned common effects obtained by the first and second aspects of the present invention, the purifying material is placed according to the depth of a lake, a river or the like where the pile body is installed. The plates are arranged in multiple stages, and the purification material is placed on some or all of the respective plates, so that the purification material can be placed at any height according to the depth of lakes, rivers, etc. Can be located.
