[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pesticide removing device for a golf course, which prevents pesticides scattered on a golf course from flowing out with rain.

[0002]

2. Description of the Related Art Generally, as a pesticide removing device on a golf course, there is one described in Japanese Utility Model Application No. 4-50204. The pesticide removing device in this golf course will be described with reference to FIGS. 5 and 6.

Reference numeral 1 in the figure is a water collecting basin, which is buried near the green or the like. A drain pipe 2 from the green is connected to the water collecting basin 1. A pesticide removal device 3 is arranged below the drain pipe 2 in the water collecting tank 1. A drain pipe 4 for discharging the wastewater from which the pesticide has been removed by the pesticide removal device 3 to the outside is connected to the lower part of the water collecting basin 1.

The pesticide removal device 3 is a removal tank 6 in which three layers are stacked.
It consists of The removing tank 6 is composed of a cylindrical container. The removal tank 6 is filled with an agricultural chemical adsorbent substance 7 such as activated carbon. On the upper side of the removing tank 6, there is fitted a perforated plate 9 in which through holes 8 having a predetermined diameter are formed vertically and horizontally at predetermined intervals.

[0005]

However, in the above-mentioned conventional pesticide removal device 3, since the removal tanks 6 are stacked in three stages, the vertical dimension becomes large. Therefore, the size of the water collecting basin 1 must be increased, and a deep hole must be dug when it is buried in the golf course. As a result, there is a problem that working efficiency is deteriorated and that construction cost is increased due to the height difference between the drain pipe 4 and the draining pond.

Further, in the above-mentioned pesticide removing device 3, since the drainage from the drainage pipe 2 is constructed so as to be sequentially transferred from the uppermost stage of the removing tank 6 stacked in three stages to the lower removing tank 6, In the removal tank 6, foreign substances such as sand are removed and pesticides are also removed. As a result, the uppermost removing tank 6 is clogged earliest, but at this time, the lower removing tank 6 is not clogged yet. As a result, even if the lower removal tank 6 is not clogged, the need for maintenance occurs,
There is a problem that running costs increase.

The present invention has been made in view of the above-mentioned problems, and it aims to reduce the running cost by suppressing the size in the vertical direction to reduce the construction cost and efficiently removing foreign matters and pesticides. An object is to provide a pesticide removal device in a field.

[0008]

[Means for Solving the Problems] In order to solve the above problems, a first invention is a pesticide in a golf course which is buried in a golf course and takes in wastewater containing a pesticide, removes the pesticide from the wastewater and discharges it to the outside. In the removal device, a drainage pipe that takes in wastewater, a first removal tank that is connected to the lower side to remove pesticides while flowing drainage from the lower side to the upper side, and in parallel to the first removal tank It is characterized in that it is configured of a second removing tank which is disposed and removes pesticides while flowing the drainage from the upper side from the upper side to the lower side.

A second aspect of the invention is characterized in that the upper part of the second removing tank is provided with a perforated plate for evenly dispersing the drainage water from the first septic tank and dropping it in a raindrop shape.

A third aspect of the present invention is characterized in that the first and second removing tanks each include a cartridge filled with a pesticide removing material.

[0011]

According to the first aspect of the invention, the wastewater taken in from the drainage pipe flows into the first removing tank from the lower side thereof, spreads in the entire area in the first removing tank, and slowly moves to the upper side. The wastewater that has moved to the upper side in the first removal tank flows into the upper side of the second removal tank, and moves from the upper side to the lower side in the second removal tank. As a result, the pesticide can be efficiently removed.

According to the second aspect of the invention, since the drainage from the first septic tank is evenly dispersed and dripped in the form of a raindrop with the perforated plate provided on the upper side of the second removal tank, the drainage is discharged from the second removal tank. It can be slowly flushed within the entire area, further improving pesticide removal efficiency.

According to the third aspect of the invention, since the cartridge filled with the pesticide removing material is provided inside, the replacement work is easy and the maintenance when the pesticide removing function is deteriorated is facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front vertical cross-sectional view showing the pesticide removing apparatus of this embodiment, FIG. 2 is a plan view showing the pesticide removing apparatus with its lid and the cartridge of the first removing tank removed, and FIG. 3 shows the pesticide removing apparatus. The right side view and FIG. 4 are left side views of the pesticide removal device.

The pesticide removal device 10 according to the present embodiment is particularly buried near the green of a golf course or the like, takes in wastewater containing pesticide, removes the pesticide from the wastewater, and discharges it to the outside. . Reference numeral 11 in the figure is a drainage pipe, into which wastewater such as rain that has fallen on the green is introduced. Reference numeral 12 is a first removal tank, which takes in wastewater and removes pesticides from the wastewater. The drainage pipe 11 is connected to the lower end of the first removal tank 12, and the drainage flows from the lower end into the first removal tank 12. In the first removal tank 12, the pesticide is removed while flowing the waste water from the lower side to the upper side.

A barbed support frame 14 is attached to the lower portion of the first removal tank 12. The support frame 14 is attached to the bottom surface of the first removal tank 12 with a predetermined dimension (approximately the diameter dimension of the drain pipe 11). This makes the first
A foreign matter removal space 12A is formed by the bottom of the removal tank 12 and the support frame 14.
Is formed. The foreign matter removing space 12A stores foreign matter such as sand that has flowed into the first removing tank 12 together with the drainage so that it does not flow into the cartridge 15 described later.

A cartridge 15 is loaded in the first removing tank 12. The cartridge 15 is placed on the support frame 14. A 2 mm square stainless mesh 16 is interposed between the support frame 14 and the cartridge 15. The stainless net 16 removes relatively large foreign matter (2 mm or more) flowing into the cartridge 15. The cartridge 15 is for facilitating replacement due to deterioration of the pesticide removal function, and is filled with a pesticide removal material such as activated carbon inside.

Reference numeral 18 is a second removing tank connected to the first removing tank 12. The second removing tank 18 is formed integrally with and in parallel with the first removing tank 12. That is, the entire lid 1
It is formed as one tank body 20 covered by 9,
A central portion of the tank body 20 is partitioned by a partition plate 21 into a first removing tank 12 and a second removing tank 18. An upper end of the partition plate 21 is slightly vacant between the partition plate 21 and the lid body 19, and this part serves as an inflow passage 22 for allowing waste water to flow from the first removing tank 12 to the second removing tank 18. As a result, in the second removing tank 18, the pesticide is removed while flowing the wastewater passing through the first removing tank 12 from the upper side to the lower side.

The upper part of the second removing tank 18 has a perforated plate support frame 2
The eye plate 26 is attached in a state of being supported by 5.
The perforated plate 26 is composed of a flat plate having a large number of small holes 27. The diameter of the small hole 27 is set so that the drainage drops like a raindrop (for example, a diameter of about 4 mm). The small holes 27 are provided longitudinally and laterally at equal intervals with a fixed size. As a result, the drainage is removed from the second removal tank 1
Disperse evenly in 8 and add little by little like a raindrop. The eye plate 26 is fixed by a fixing bolt 28 while being supported by the eye plate support frame 25.

In the second removing tank 18, a cartridge 30 similar to the cartridge 15 of the first removing tank 12 is loaded below the perforated plate 26. The cartridge 30 is supported by a support frame 31 whose bottom is raised, and a drainage space 18A is provided between the bottom surface of the second removal tank 18 and the cartridge 30. A stainless net 32 similar to the stainless net 16 of the first removing tank 12 is interposed between the cartridge 30 and the support frame 31.

A water drain window 33 is provided at the lower end of the second removing tank 18.
Are provided on the other three surfaces excluding the partition plate 21.
The drainage window 33 is a window for discharging the drainage that has passed through the cartridge 30 to the outside, and the height dimension thereof is the support frame 3
It is set lower than 1 and faces the drainage space 18A.
Drainage from the drainage window 33 flows into the pond via an external drainage pipe (not shown).

The pesticide removal device 10 configured as described above
Is buried in the vicinity of the green, etc. Since the pesticide removing device 10 has two removing tanks 12 and 18 arranged side by side so as to keep the size in the height direction low and has a compact structure, the embedding hole need only be shallow. That is, the pesticide removal device 1
A shallow burial hole corresponding to 0 is dug, and the pesticide removal device 10 is installed in this burial hole. Drain pipe 1 of pesticide removal device 10
1 and a drainage pipe (not shown) buried in a green or the like are connected. After embedding the pesticide removal device 10 in the hole, cover the exterior with artificial turf or the like to give consideration to the appearance. The height difference between the pond into which the waste water flows and the pesticide removal device 10 does not cause a problem because the burial hole is shallow.

The pesticide removing device 10 operates as follows when it is buried in the vicinity of the green.

When a large amount of water overflows in the golf course, such as when a large amount of rain falls in a short time, this drainage flows into the drainage pipe buried in the green or the like, and the drainage pipe of the pesticide removing apparatus 10 is discharged. It flows through 11 and flows into the first removal tank 12.

In the first removing tank 12, drainage flows from the drain pipe 11 into the foreign matter removing space 12A on the lower side. In this space 12A, something heavier than water such as sand or stainless steel net 1
A foreign substance of a size that cannot pass 6 is accumulated.

The drainage that has passed through the stainless steel net 16 slowly flows through the entire area of the cartridge 15 from the lower side to the upper side, and the pesticide is adsorbed by the pesticide removing material inside.
The wastewater that has passed through the cartridge 15 has an inflow passage 22.
Through the second removal tank 18. This second removal tank 1
In 8, the drainage first flows into the eye dish 26. The drainage is temporarily stored in the eye plate 26 and drops from the small hole 27 to the cartridge 30 below it in a raindrop shape. Then, the wastewater that drops like rain drops does not concentrate locally in the cartridge 30, spreads over the entire area, and falls while flowing slowly. As described above, the pesticide removing material efficiently adsorbs the pesticide by causing the waste water to flow slowly throughout the cartridge 30. Thereby, the cartridge 15 of the first removal tank 12
The pesticides in the wastewater that could not be removed by the method are almost completely removed.

The drainage that has passed through the cartridge 30 flows out from the drainage window 33 at the lower end to the outside and flows into the pond through the external drainage pipe.

When replacing the cartridges 15 and 30, the artificial grass and the like are removed, the lid 19 is removed, the used cartridges 15 and 30 are taken out, and new cartridges 15 and 30 are loaded.

As described above, since the pesticide removing device 10 is constructed by arranging the first removing tank 12 and the second removing tank 18 side by side and keeping the vertical dimension low, the pesticide removing device 10 is compact. When the golf course is buried in the golf course, the burying hole can be made shallow, and the construction cost can be reduced. The height difference between the pond and the drainage is not a problem.

Since the pesticide removing device 10 has a simple structure and does not have an electric part, the device can be manufactured at a low cost, there are almost no failures, and the device reliability is high.

Further, in the pesticide removing device 10, the wastewater after the foreign substances are removed in the foreign substance removing space 12A is slowly flowed through the entire regions of the cartridges 15 and 30 to efficiently remove the pesticide. Will be able to.

Further, the cartridge 1 of the first removing tank 12
5 and the cartridge 30 of the second removal tank 18 are not extremely different in the reduction rate of the pesticide removal function, and both of them similarly deteriorate in function. Therefore, the replacement time of one of the cartridges 15 and 30 does not become extremely short, and as a result, the replacement time of the cartridges 15 and 30 can be extended, and the running cost can be reduced.

Further, when the pesticide removing function is deteriorated,
Since the cartridges 15 and 30 are replaced, the replacement work becomes easy.

[0034]

As described above in detail, the pesticide removal device for a golf course of the present invention has the following effects.

(1) Since the first removing tank and the second removing tank are arranged side by side and the size in the vertical direction is kept low to make the apparatus compact, the construction cost can be reduced.

(2) In the pesticide removal device, wastewater is slowly flowed from the lower side to the upper side in the first removal tank and from the upper side to the lower side in the second removal tank, so that the pesticide is removed. It can be removed efficiently.

(3) Since the drainage from the first septic tank is evenly dispersed and dripped in the form of a raindrop with a perforated plate provided on the upper side of the second removal tank, the drainage is more efficient in the second removal tank. Can be spread over the entire area and slowly flowed, and the pesticide removal efficiency can be further improved.

(4) Since the pesticides are efficiently removed while slowly flowing over the entire area in the first removal tank and the second removal tank, the pesticide removal function in each removal tank declines on average, and the replacement time Can be extended. As a result, the running cost can be reduced.

(5) Since the cartridge having the pesticide removing material filled therein is used, the replacement work is easy and the maintenance when the pesticide removing function is deteriorated is facilitated.
