Contamination of golf club funds or reservoirs is caused by fertilizers, pesticides, and contaminants in livestock farms, which often cause eutrophication of golf club funds or reservoirs. Eutrophication refers to a phenomenon in which abnormal growth of red tide or plankton occurs due to the increase of nutrients in freshwater due to decomposition of organic matter by microorganisms.

Since eutrophication destroys the ecosystem of golf course funds or reservoirs and kills all living organisms in freshwater, various methods to prevent eutrophication have been attempted in various ways. For example, chemicals and flocculants are used to remove contaminants. The method of flocculating or sedimenting, the method of floating contaminants using pressurized air, the method of improving water quality using microorganisms, the method of removing nutrients using aquatic plants, etc. Common features include temporary effects, but long-term effects are difficult to expect, costly, and water purification efficiency drops significantly with the season.

As a conventional technique for purifying water using aquatic plants, registered utility model 20-202650, registered utility model 20-255250, patent registered 10-438351, registered utility model 20-0363057, etc. Water purification method and apparatus using the same, the main contents of them are the floating body for floating artificial aquatic islands on the water and the outer surface made of metal material such as stainless steel, which is connected to this floating body and has square or various shapes. It is composed of a base mesh formed on the inner side of the frame and the outer frame, a mesh pad (net mesh mat) positioned to support aquatic plants, and a porous adsorbent layer in the mesh pad layer or above or below the mesh pad. The first is the mobilization of cranes for the installation of large outer frames and internal structures. Expensive and often cause damage in the hurricane or winter, when the replacement or repair of damaged and replacement deulmyeo complex and expensive are facing the problem of the addition processing of secondary waste. In addition, there is a drawback that only the part where the aquatic island is placed is purified because the standing water such as golf club funds, ponds, and lakes is not in motion.

Patent No. 10-0478443 is a water purifying bag composed of a water stacking box, a water box, a water purifying bag, etc. in a predetermined section of a bypass stream connecting upstream and downstream of a water barrier formed by blocking a river or a river. Is a method of purifying the water quality contaminated by the water purification material in the water purification bag placed in the water supply box while the upstream water passes through the inside of the water supply box stack as a bag formed of fine pores. 0353509 is a water purification device for local small rivers.The charcoal is inserted into the synthetic resin case with mesh or numerous holes to connect several cases in a line according to the width of the stream, and the connection is fixed between the left and right shores fixed to the stream. Alternatively, the water purification method is to fix the contaminated water as it passes through the charcoal on the floor. As a clogging phenomenon in which foreign matter adheres to the water purification bag and the mesh body formed by 1, it has a disadvantage in that it obstructs the flow of water and cleans the blocked portion every time. In addition, the large and small foreign objects on the surface and inside of the charcoal sticks to the charcoal, so that the charcoal does not function properly or needs to be replaced quickly, and it is easily damaged by water or trees or stones floating upstream during flooding. There is a problem in using for a long time.

Therefore, it has been developed a water purification method for golf club funds that can be easily installed while solving the problems appearing in the prior art and minimizing the installation cost. In other words, TN (phosphorus), TP (nitrogen), chlorophylla, turbidity, BOD (biological oxygen demand) and COD (chemical oxygen demand), which are euthanasia-causing substances such as golf club funds, park reservoirs, ponds, and fishing grounds, where water does not move It is a technology that provides a water purification method that can remove the SS (floating substances), odor, etc. at a simple and low cost, and can be used for a long time and can be used for a long time.

In order to achieve the above object, such as a golf course pond or a park reservoir where water is standing, the water depth is 1m to 3m and the water does not move and consists of a device for purifying with charcoal and aquatic plants while moving the standing water.

First, the mesh body (1) into which char can be put in accordance with the depth of the water, and the mesh planting bag and the mesh body (1) capable of planting aquatic plants are fixed on the side and top of the mesh body (1) without flowing in the water. It consists of a fixed link that allows the mesh (1) containing the char to be connected to each other so that the water circulating without passing through the charcoal mesh (1) to send far away to the other side water circulation motor (13) Is the basic construct.

In more detail, Figure 1 is a mesh (1) and the mesh body (1) containing char as a water circulation underwater motor (13) containing the char is a main element of the present invention so that the char does not count out from the inside It consists of inner mesh and synthetic resin net to protect inner mesh on the outside and to hold the mold like cylinder and square shape. These meshes and synthetic resin networks can be easily and cheaply purchased on either side of the market. The upper part of the mesh body (1) consists of the upper plant pouch (3) so that the water plant (5) is soaked with sand and soil to settle the roots, and the submerged plant (1) side containing the charcoal (1) 6) It consists of side planting pockets (4) so that the roots can be seated, and the upper and lower corners of the charcoal meshes (1) are connected to each other so that the whole charcoal meshes (1) are not moved in water. It is composed. Purified plants (5) and submerged plants (6) grown in charcoal upper layer pouches (3) and side pouches (4) are fed with nutrients such as nitrogen and phosphorus adsorbed and concentrated in large quantities as eutrophication. It prevents excessive reproduction of algae such as green algae, and serves to primarily prevent foreign matter or suspended matter in the water from directly accessing the mesh body (1). In addition, fish or aquatic insects eat or decompose suspended solids that cling to aquatic plants to prevent clogging of the mesh (1), thereby enabling long-term water purification and providing spawning and habitat space for fish, aquatic insects, and birds. They also feed on algae in the water, preventing them from multiplying.

The contents inside the charcoal mesh body (1) sinks in water to prevent the phenomenon that the mesh body (1) containing charcoal in the lower part of the mesh body (1) enters into the water and does not sink in water and loses balance and floats. A certain amount of sand is laid to hold the center of gravity, charcoal is placed on it, and a certain amount of sand is placed so that aquatic plants can grow on the charcoal. The side planting bag (4) is mixed with a certain amount of sand and soil so that the submerged plants (6) can grow. Let's do it. The amount of sand that enters the mesh body (1) is appropriate for 5 ~ 40% of the capacity of the mesh body (1) depending on the depth of the water, charcoal 60 ~ 95% is appropriate. If the amount of sand is more than 40%, it is not preferable to reduce the water purification power. The charcoal used here is not specially used for wood charcoal, chaff charcoal, activated charcoal, granular, powder, etc., but it is appropriate to apply chaff charcoal in consideration of installation cost and purification rate in the place where water is accumulated like golf course fund. . Chaff charcoal is crescent-shaped as it is, so it has a lot of space, so clogging caused by foreign matter is much less than wood charcoal, and the cost is low and the water purification rate is very good.

1 is a case that keeps a constant distance from the water circulation underwater motor 13 and the water circulation underwater motor 13 and the charcoal mesh body 1 by the pipe and the water circulation underwater motor 13 to create a flow of standing water without moving and The water circulation underwater motor 13 is placed inside the case and the pipe connected to the water circulation underwater motor 13 is composed of small pipes at an angle of 30-45 degrees in the middle of the pipe to allow the flow of water to go forward and upward.

2 is a concentrated batch type water purification method in which the mesh body 1 containing charcoal is rotated around the water circulation submersible motor 13 around the mesh body 1 in consideration of the landscaping and aesthetics of the golf course fund. It can be connected in various forms such as radial, square, and triangle. Since the charcoal mesh body (1) is piled around the underwater motor (13) in all directions so that all the water passes through the charcoal when the underwater motor (13) absorbs water, the water quality is purified and transported far forward through the pipe or It is a method of moving water from bottom to top.

In addition, the aquatic plants growing in the upper side of the charcoal mesh (1) is aesthetically beautiful, and the submerged plants growing in the side planting pockets provide a place for fish to spawn and play.

In another embodiment, the water purifying principle is the same as the above method, but the charcoal mesh (1) according to the structure of the golf course fund or pond. Place 5-10 in a row. If it needs to be replaced due to the charcoal purification function, it is effective to bundle 5-10 charcoal mesh bodies (1) for the sake of collection, and it is effective to give the movement of standing water on both sides of the pond. 13) and pipe piping.

In addition, charcoal is placed directly below the top soil of the golf course fund, so water purification efficiency is more effective and long-term purification can be expected.

In an embodiment of the present invention, BOD (biological oxygen demand), COD (chemical oxygen demand), SS (floating material), TN for three months (2005.9-2005.11) targeting two funds of a golf course (Sunun Lake Golf Club) (Total Nitrogen), TP (Total Phosphorus), the water purification rate was 74% to 76% for BOD and COD, 90 to 92% for SS, 64% to 84% for TN, 34% for TP ~ 45% improvement. The results of measuring and analyzing the water quality applied to the golf course fund by the method according to the present invention are as follows.
