Description

[Detailed Description of the Invention] The present invention relates to a purification device for an ornamental pond for colored carp, goldfish, etc.

Traditionally, when ornamental fish such as Nishikigoi and goldfish were kept as pets in ponds set up in home gardens or schools, the water in the pond, which was initially clear, turned green-blue due to the growth of algae caused by sunlight. In addition, excrement from Nishikigoi and goldfish, undigested feed, etc. settle and accumulate at the bottom of the pond tank, and each time these ornamental fish grow, the water becomes cloudy. The pond water must be frequently replaced and cleaned, which is extremely troublesome and tends to remain in the above state for a long period of time.A relatively simple device can easily purify a large amount of pond water. I realized that there was a need for a device that could do this. Therefore, in the present invention, the septic tank is formed from a cobblestone filtration chamber, a storage chamber, and a sludge settling chamber, and the cobblestone filtration chamber and the storage chamber are divided into left and right by a partition plate, and the bottom end of the partition plate is A communication port is formed through which the treated water flows submerged, and the cobblestone filtration chamber and sludge settling chamber are divided into upper and lower sections using rostres, and a cobblestone layer is formed between the cobblestone filtration chamber and the storage chamber, and the sewage, sludge, etc. of the ornamental pond is formed. This was done to purify the ornamental pond by pumping up the water and pouring it into the boulder filter chamber.

An embodiment of the present invention will be described with reference to the attached drawings. 1 is an ornamental pond for Nishikigoi, goldfish, etc. installed in a home garden or school; 2 is a depression formed in the bottom of the tank of the ornamental pond; 3 4 is a square box-shaped FRP septic tank buried in a suitable location around the ornamental pond 1; 4 is a partition plate that partitions the septic tank 3 into left and right sections; the left side is a cobblestone filtration chamber 5 for sewage, sludge, etc.; The right side thereof is a storage chamber 6 for treated water, and the volume ratio of the cobblestone filtration chamber 5 and the storage chamber 6 is about 7:3 or 8:2, and the total size is about 1 m ³ . 7 is a layer of cobblestones spread over the bottom of the cobblestone filtration chamber 5, and 8 is a cobblestone layer spread over the top of the cobblestone filtration chamber 5.
Place cobblestones of about 20 to 50 mm at height 7 of cobblestone filtration chamber 5.
It has accumulated to about 80%. 9 is a triangular pyramid-shaped sludge settling chamber formed at the bottom of the rostre 7,
A sludge drainage pipe 11 is connected to one side of the lower sloped bottom 10 and raised up to the ground level. 12 is a layer of cobblestones piled up in the storage chamber 6; 13 is a communication port formed at the lower end of the partition plate 4 through which treated water flows submerged; 14 is an inflow gutter for the supernatant liquid at the upper end of the storage chamber 6; 15 is one end A return pipe for treated water connected to the inflow gutter 14 and having its other end facing the ornamental pond 1; 16 is wastewater having one end input into the depression 2 of the ornamental pond 1 and the other end facing the cobblestone filtration chamber 5;
The sewage in the ornamental pond 1 is pumped by the pump 17 connected to the introduction pipe 16, which is an introduction pipe for sludge, etc.
Pump up and feed sludge, etc.

After scooping up colored carp, goldfish, etc. from the ornamental pond 1 and transferring them, the feeding pump 17 is activated to draw up sewage, sludge, etc. from the ornamental pond 1 and pour it into the cobblestone filter chamber 5. This inflowing sewage percolates through the cobblestone layer 8 laid in the cobblestone filtration chamber 5,
The sludge is washed down through the gaps in the roistle 7 and gradually deposited on the inclined bottom 10 of the sludge settling chamber 9.
In addition, the treated water from which sludge and dirt have been removed by permeating through the cobblestone layer 8 flows submergedly through the communication port 13 at the lower end of the partition plate 4 and flows into the storage chamber 6. By gushing out the layer 12 from the bottom to the top, a better purified supernatant liquid is obtained. This is made to flow into the ornamental pond 1 again from the inflow gutter 14 via the return pipe 15. By repeating such purification work repeatedly, the water in the ornamental pond 1 is gradually purified, and the dirt and sludge in the wastewater naturally settles from the rostol 7 and is deposited in the sludge settling chamber 9. It will be done. When the purification process is completed, the tip of the introduction pipe 16 is inserted into the drain pipe 11, and the sludge is pumped up by the feed pump 17 and discharged from the other end of the introduction pipe 16 to the outside. By carrying out such treatment work appropriately while monitoring the degree of contamination of the ornamental pond 1, the ornamental pond 1 can be kept clean at all times and a good breeding environment can be ensured.

In the above case, the rostrum 7 at the bottom of the cobblestone filtration chamber 5 was laid approximately horizontally, but it can also be supported tilted upward to the left with the communication port 13 side lowered to facilitate submergence of the treated water. . Furthermore, the septic tank 3 of the present invention is buried underground so as not to damage the surrounding scenery.

The present invention, as mentioned above, is installed at appropriate locations around the ornamental pond 1.
A septic tank 3 made of FRP is buried, and the septic tank 3 is divided into left and right sections with partition plates 4, one of which is used as a cobblestone filtration chamber 5 for sewage, sludge, etc., and the other is used as a storage chamber 6 for treated water. , the rostol 7 is placed at the bottom of the cobblestone filtration chamber 5, and the top of the rostol 7 is
Cobblestones with a stone diameter of about 20 to 50 mm are placed in the cobblestone filtration chamber 5-7.
A cobblestone layer 8 is formed by piling up to about 80%,
A sludge settling chamber 9 is formed in the lower part of the rostol 7,
A sludge drainage pipe 11 is connected to the lower inclined bottom 10 of the sludge settling chamber 9, and the other end of the sludge drainage pipe 11 is raised up to the above ground level, and the lower end of the partition plate 4 has the following features: A communication port 13 through which the treated water flows submergedly from the cobblestone filtration chamber 5 to the storage chamber 6 is formed as an opening, and the aforementioned storage chamber 6
A cobblestone layer 12 is formed by piling up boulders, and an inflow gutter 14 for the supernatant liquid is formed at the upper end of the storage chamber 6, one end of the treated water return pipe 15 is connected to the inflow gutter 14, and the other end is connected to the inflow gutter 14. into the ornamental pond 1, one end of the introduction pipe 16 for sewage, sludge, etc. is introduced into the ornamental pond 1, the other end is made to face the cobblestone filtration chamber 5, and the sewage, sludge, etc. from the ornamental pond 1 is introduced into the introduction pipe 16. Since the ornamental pond purification device is constructed by connecting a feed pump 17 that pumps up water, it is possible to purify the ornamental pond in a timely manner while constantly monitoring the sewage situation, which is very important for ornamental fish enthusiasts. It's convenient. Further, the overall structure of the device is extremely simple, and therefore it brings about various effects such as being able to easily and quickly purify a large amount of pond water using a simple device.
