Description

Description: TECHNICAL FIELD The present invention relates to an improvement of a water purification device.

[Prior art] Conventionally, in gardens and park ponds, etc., the water quality is purified,
In order to further increase the transparency of water, a sand filtration tank is provided in a part of a water channel to remove dust floating in water.

[Problems to be solved by the invention]

However, according to the structure in which the sand filtration tank is simply provided, clogging is likely to occur and the filtration function is easily lost. Especially in summer, there is a drawback that blue berries are generated due to eutrophication and the filtration function is lost early.

Therefore, conventionally, medicine is sometimes used to exterminate blue water, but in pond such as gardens and parks, carp and goldfish are often kept for appreciation, so depending on the type of medicine,
Alternatively, carp and goldfish may be killed when the amount of the medicine exceeds a predetermined amount.

[Object of the Invention] The present invention has been made in view of the above points, and can remove dust floating in water, can prevent the occurrence of blue water, and furthermore, carp and goldfish can be removed by chemicals. An object of the present invention is to provide a water purification device capable of increasing the transparency of water without dying.

[Means for solving the problem]

The present invention has the following configuration to solve the above-described problem. That is, a filtration tank is provided at the upper part of the water purification device main body, provided with a water network at the top and a net body at the lower part, a filter medium is laminated between the water network and the net body, A germicidal lamp storage tank that is arranged at the latter stage of the filtration tank and irradiates the water sent from the filtration tank with ultraviolet rays, and a treated water that is arranged at the latter stage of the germicidal lamp storage tank and is treated by the germicidal lamp storage tank. It is composed of a treated water storage tank for storing water.

Then, the treated water in the treated water storage tank is sent to pond water by a pump, and a part of the treated water is directly returned to the filtration tank.

[Action]

According to the water purification device described above, the water to be treated falls naturally into the filtration tank from the water flow network, the suspended bacteria contained in the water are filtered, and the water in the filtration tank is naturally sent to the germicidal lamp storage tank by water pressure. Blue water is exterminated by the flow and ultraviolet rays from the germicidal lamp, and organic substances contained in water are decomposed and removed.

In addition, part of the treated water sent to the treated water storage tank circulates through the pond outside the water purification device main body and flows again into the filtration tank, and further, part of the treated water in the treated water storage tank is transferred to the filtration tank. The particles which are directly refluxed and pass through the filter tank are treated again with the filter medium, and activated water which is oxidized by ultraviolet rays or ozone generated from an ultraviolet lamp is mixed with impurities in the water between the filter tanks. Contact reaction causes COD and BOD to be easily oxidized and decomposed. Then, the remaining water enters a garden or a park pond, and after that, circulates again into the filtration tank and is treated.

〔Example〕

 The present invention will be described below with reference to FIG.

In the figure, reference numeral 1 denotes a water purification device main body, which is embedded in a pond such as a park or a garden. Reference numeral 16 denotes a filtration tank disposed in the water inflow portion of the water purification device main body 1, which is provided with a water passage network 17 at an upper end portion and a net body 3 at a lower portion. Reference numeral 2 denotes a filter material which is formed by laminating a large number between the water flow network 17 of the filter tank 16 and the net body 3, and is formed of, for example, yarn in a ball shape. 4 is the inside of the water purification device main body 1,
The submersible pump tank formed adjacent to the filtration tank 16, the submersible pump 5 provided inside the submersible pump tank 4, and the submersible pump tank 6 formed inside the water purification device main body 1 and adjacent to the submersible pump tank 4. A germicidal lamp storage tank, 7 is a germicidal lamp storage tank 6
The ultraviolet sterilization lamp is housed in, for example, 12 ultraviolet sterilization lamps of 65 watts.
If 12 UV-sterilizing lamps of 65 watts are housed, the pond can handle about 700 tons of water.

Reference numeral 8 denotes a treated water storage tank formed inside the water purification device main body 1 and adjacent to the germicidal lamp storage tank 6, and reference numeral 9 denotes a pump for pumping water from the treated water storage tank 8, which is a park or the like. It is configured to send the treated water to a garden pond. Reference numeral 10 denotes a pipe having one end connected to a pipe connected to the pump 9 and the other end arranged at the upper end of the filtration tank 16 for filtering a part of the water treated by the filtration tank and the ultraviolet sterilizing lamp. It is configured to return to the tank. When a part of the treated water is returned to the filtration tank, the activated water reacts with impurities in the filtration tank to further promote water purification.

11 is a stopper provided at a desired position of the pipe 10,
The amount of water returned to the filtration tank 16 is adjusted.

Reference numeral 12 denotes a plug connected to a pipe connected to the water pump 9, which is configured to regulate the amount of water to be sent to a park or garden pond. Reference numeral 13 denotes a water discharge nozzle provided below the mesh body 3 of the filtration tank 16, and reference numeral 14 denotes an air diffuser provided below the water discharge nozzle 13, which injects air. When the filter medium 2 contains dust, clear water is injected from the water discharge nozzle 13,
In addition, air is injected from the air diffuser 14 to the filter medium 3 so that the filter medium 2
It is configured to remove dirt. Dust separated from the filter medium 2 is discharged to the outside of the water purification device main body 1 by the submersible pump 5.

According to the water purification device, the water to be treated from the pond of a garden or a park to the inside of the filtration tank 2 falls naturally from the water flow network 17 and the suspended matter contained in the water is filtered.

Further, the water in the filtration tank 2 flows into the germicidal lamp storage tank 6 by water pressure. When the flowing water is irradiated with ultraviolet rays, the water in the pond and the like is exterminated and the organic matter contained in the water is decomposed and removed, thereby promoting the growth of carp and goldfish in the pond.

Further, the treated water sent from the water pump enters a pond in a garden or a park, circulates again into the filtration tank 2, and is treated again with the filtration tank and ultraviolet rays.

〔The invention's effect〕

According to the present invention, as described above, water in a garden or park pond is treated with a filtration tank and ultraviolet light, and the treated water enters the pond, circulates again into the water purification device, is treated and treated again. Part of the waste water is configured to be directly recirculated to the filtration tank, so that the water is reliably treated, and the activated water reacts with impurities in the filtration tank to further promote water purification. effective.

In addition, ultraviolet rays from an ultraviolet sterilizing lamp exterminate blue water and increase the transparency of water. Further, the organic matter contained in the water is decomposed and removed by the ultraviolet rays from the ultraviolet sterilizing lamp, which has the effect of promoting the growth of carps and goldfish in gardens and park ponds.
