Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lake purification apparatus for purifying lakes including polluted yacht harbors and marinas.

[0002]

2. Description of the Related Art Conventionally, in lakes and marshes including marinas and yachts harbors (in this specification, marinas and yachts harbors are also included in lakes and marshes), pollutants that are submerged or floating therein are removed by dredging or the like, Alternatively, in order to suppress the growth of phytoplankton such as blue powder, water is introduced from a river to a lake at a certain position and then returned to the river from another position in the lake to generate a flow. There is a movement to purify. However, the former is direct, but as pollution is progressing, it is necessary to do this continuously, and in that sense the economic burden is very large, and in addition, the problem of dumping dredged sludge is also a problem. is there. The latter requires a large amount of work, and the economic burden is extremely large.

[0003]

As described above, since a simple and economical lake purification device has not been provided yet,
In the present invention, a lake purifying apparatus that can purify a lake efficiently and economically with a small apparatus by developing a device that utilizes a purifying action by bacteria and is capable of automatic operation. It is intended to be provided.

[0004]

The gist of the present invention is to mount a plurality of ceramic cylinders on the upper and lower surfaces of a support box, and to attach a float to the support box to float the ceramic cylinders on the surface of a lake. In addition, the lake purifying device has wire rods that are connected to anchors arranged on the bottom of the lake in the support box.

Since the support box holds the ceramic cylinder, the size and shape of the support box is not limited to a particular one. It is in the shape of a rectangular parallelepiped and has sufficient strength so that it will not be easily damaged even by strong waves. For example, a partition frame or the like is arranged inside to reinforce the framework. The material is not limited to a particular material. The diameter and length of the ceramic cylinder can be freely determined. The material is diatomaceous earth, but other ceramics are not inconvenient. Further, it is preferable that the above-mentioned ceramic cylinder is formed to be porous. It is a good idea to prepare the conditions that are favorable for the growth of microorganisms.
The geometry of the float is also not limited to a particular one. Any material may be used as long as it has a buoyancy capable of floating the support box holding the ceramic cylindrical body, has sufficient strength against waves and does not easily corrode.
For example, plastics or rustproof metal can be used. Needless to say, those which do not adversely affect microorganisms are suitable.

The wire may be a chain or rope which does not easily corrode, and has sufficient strength to prevent the floating support box from moving. Of course, it is also necessary to have a sufficient length to allow the support box to float. The above wire is
Join the upper ends of the branch wires to the bottom four corners of the support box,
The lower end of the main wire is suitably connected to the upper end of the main wire, and the lower end of the main wire is suitably connected to an anchor arranged at the bottom of the lake. The anchor is simply submerged or buried at the bottom of the lake.

[0007]

Since the present invention is constructed as described above, it can be installed in a lake, swamp, marina, yacht harbor or the like where pollution has progressed to purify it. When the lake is also used as a fish farm, as a result, the target fish can be grown well and can be obtained deliciously. Prepare a suitable number of lake purification devices according to the size and depth of the lake, and install these lake purification devices at appropriate intervals. The anchor to which the wire is connected is submerged or buried in the bottom of the lake, whereby the floating position of the lake purification device connected to the upper end of the wire is determined.

The lake purification apparatus floats on the surface of the lake by the float, and as described above, floats within a certain range by the wire connected to the anchor. Since the plurality of ceramic cylinders have favorable growth conditions for microorganisms, aerobic bacteria and the like grow, thereby decomposing various pollutants in lake water and proceeding with purification. This lake purification device vibrates or oscillates in various directions with waves that are constantly generated on the lake surface due to the influence of wind, etc.
When it rises, it comes in contact with air and takes it in, promotes the growth of bacteria, promotes the diffusion of nutrients and metabolites of bacteria in the ceramic cylinder by the impact or vibration of strong waves, and removes the frog. Do it. In this way, bacteria can grow well in the ceramic cylinder and a stable ecosystem can be created. As described above, this lake purification device is extremely economical because it can be operated unattended by utilizing the natural power of waves.

Further, with this apparatus, the ammonia component, which is stress on the fish in the lake, is oxidized to form nitrate radicals.
It reduces the stress on fish and causes a large amount of zooplankton to grow. However, it has a great effect on the growth of delicious fish. Furthermore, the nitrate radicals generated as described above promote the supply of oxygen to the lake bottom, while the large-scale growth of zooplankton as described above has a function of suppressing the growth of phytoplankton, and As a result of activation, the growth of cyanobacteria, water-bloom, etc. is suppressed, and as a result,
It makes the water transparent, promotes ecological complexity of the lake, prevents desertification of the lake bottom, that is, the water moves to the transparent side as a condition for vegetation growth on the lake bottom. In this way, diatoms flourish, the water becomes clearer, and the fish become more delicious.

The condition is changed to the transparent one. In this way, diatoms flourish, the water becomes clearer, and the fish become delicious.

[0015]

According to the present invention, pollutants in lakes and marshes can be decomposed and purified by bacteria that adhere to and multiply on ceramics cylinders, and a support box on which they are fixed floats on the lake surface by a float. By vibrating or oscillating due to the waves generated on the surface of the lake, air is favorably taken in, promoting the diffusion of nutrients and metabolites of bacteria on the surface of the ceramic cylinder and in the pores, and It promotes proliferation and facilitates frog detachment. That is, it can be driven by the natural force called wave energy, and the lake can be purified very economically. In the present invention, the ammonia content is further oxidized to form nitrate radicals, which reduces stress in fish and allows zooplankton to multiply. Further, the nitrate root promotes the supply of oxygen to the bottom of the lake, and the growth of zooplankton has a function of suppressing the growth of phytoplankton. As a result, the water becomes transparent, diatoms flourish, the water becomes cleaner,
Fish is delicious.
