Description

  The present invention is a floating island purifying apparatus that purifies polluted water in a closed system water area such as a pond, a moat, and a lake.

  Conventionally, the purification of polluted water in closed water areas such as ponds, moats, and lakes has been carried out by physical purification methods using coagulation sedimentation using chemicals or filtration devices using filter media. These methods have problems such as adverse effects on the environment and high initial costs, and are difficult to implement in practice.

  Moreover, in the conventional floating island type purification apparatus, since the apparatus for purifying water quality etc. is arrange | positioned on a floating island, the weight became heavy and the operation | work at the time of installation and a maintenance was difficult.

  In addition, research on water purification plants that absorb a large amount of these substances against eutrophication substances such as nitrogen and phosphorus in polluted water has been conducted, and many results of these experiments have been reported. However, in order to actually use it as a water purification device, the maximum amount that can absorb the causative substance is determined in proportion to the growth limit of these plants, and it is necessary to cut the plants. There are problems such as plant management due to fluctuations, and it has not been put to practical use.

  Also, water purification plants that absorb a lot of substances that cause eutrophication such as nitrogen and phosphorus, when planted in floating island type purification equipment, the roots are difficult to fix, and there is a risk of falling after planting It was difficult to keep plant growth stable.

  Also, in closed waters such as ponds, moats, and lakes, the degradation of water pollutants by microorganisms such as phytoplankton and zooplankton does not provide a breeding ground for the efficient propagation of these microorganisms. There is a problem in that stable water quality purification cannot be performed because sufficient air cannot be secured for these microorganisms to be active.

  The present invention has been made to solve such problems, and it is possible to reliably plant water purification plants at low cost without adversely affecting the environment, and to maintain plants of these plants and plants due to climate change. It is an object to provide a floating island type purification device in a closed water area that can reduce the labor of management and can stably purify water by microbial treatment.

Means for solving this problem are as follows.
The present invention is an apparatus used for purification of polluted water in closed water areas such as ponds, moats, and lakes, and planted water purification plants that absorb a large amount of substances that cause eutrophication such as shrike rush and broom. There is an upper part of the resinous skeleton body and a lower part of the resinous skeleton body that can efficiently propagate microorganisms involved in water purification, and the upper part and the lower part of this network skeleton body are joined to increase the strength. It is a floating island type purification device that is equipped with a frame. It does not use chemicals and filtration devices necessary for conventional coagulation sedimentation, and does not adversely affect the environment, and it is necessary to introduce an expensive purification device The initial cost can be reduced.

  In addition, the present invention does not include a device for purifying water quality, and uses a resinous network skeleton body and a resin reinforcing frame, so it is lightweight, and more buoyant than those made of metal. Since many can be obtained, installation and maintenance work can be easily performed.

  In the present invention, a water purification plant that absorbs a large amount of substances that cause eutrophication, such as shurogayatsuri and gypsophila, are planted on the upper part of the resinous reticulated skeleton, and the roots of these plants grow with the growth. It has become possible to keep the growth of these plants stably by being entangled with the reticulated skeleton and preventing the collapse of these plants.

  In addition, the present invention can be easily drawn to the lake shore by fixing the reinforcing frame covering the resin-made net-like skeleton to the lake shore, etc., so that it is used as a water purification plant. These plants needed to absorb nitrogen, phosphorus, etc., which cause eutrophication continuously, and management of these plants due to climate change was facilitated.

  Further, in the present invention, the lower part of the resinous reticulated skeleton body is a place suitable for the propagation of microorganisms such as phytoplankton and zooplankton, and these microorganisms propagate efficiently through the food chain and can stably purify water. It became a thing.

  In addition, the present invention provides an air supply device below the lower part of the reticulated skeleton body in order to more actively carry out the activities of microorganisms such as phytoplankton and zooplankton propagated in the lower part of the resinous skeleton structure. It became possible to forcibly supply air, and the activity of these microorganisms became active, and water quality purification could be performed more efficiently.

  Further, the present invention provides an air pipe for connecting the air supply device and the blower by installing a blower for sending air into the air supply device in a resin box provided in the center of the resin skeleton. This simplifies the process and makes it easier to perform installation and maintenance work.

  In addition, the present invention provides power supply for operating the blower by using a solar cell module or a wind power generator using natural energy such as sunlight or wind power installed on the top of the resin box. The electric wiring of the blower can be simplified, the work for installation and maintenance can be easily performed, and the running cost can be further reduced.

  As described above, according to the present invention, the water purification plant stably absorbs a large amount of substances that cause eutrophication and can stably perform water purification, and is involved in water purification. The microorganisms can be efficiently propagated by the resinous skeletal structure, and the activity of the microorganisms is activated by the air supply, so that the water purification by these microorganisms can be stably performed.

  Further, according to the present invention, since an expensive water purification device such as a filtration device is not used, the initial cost can be reduced, and a water purification method using chemicals such as coagulation sedimentation is not used, and sunlight, wind power, etc. Since power is supplied to the blower using natural energy, the running cost can be reduced.

  In addition, according to the present invention, the overall weight can be reduced by using resin as a material, and it can be fixed to a lake shore, etc., so that water purification plants can be easily pruned and plants can be managed by climate change. Also during installation and maintenance of the apparatus, the installation work and maintenance work can be easily performed because the apparatus is lightweight.
