It includes a vertical tube 33 to be installed.

In addition, a plurality of connection pipes 32B communicating with the inner tank 32 are provided on the separated lower space of the inner tank 32, and the outer tank 31 has rainwater from the rainwater collecting tank 20 to the inner tank 32. The inlet 31A for supplying the water and the discharge pipe 31B for supplying the water stored between the outer tank 31 and the inner tank 32 to the storage tank 40 are provided.

At this time, the safety net (31A ') is installed on the upper side of the inlet (31A) to promote the safety of the operator when the cleaning operation to remove the contaminants accumulated in the inner tank (32).

In addition, a plurality of storage plates 34 are horizontally installed on the inner side surface of the outer tank 31 and the outer side surface of the inner tank 32 so as to alternately spaced apart from each other at predetermined intervals. As the flow of water stored in the settling tank 30 is suppressed, precipitation of pollutants is naturally induced more.

In addition, the internal tank 32 is induced so that the contaminants contained in the initial rainwater and rainwater from the initial rainwater collection tank 10 and the rainwater collection tank 20 do not relatively accumulate in the deep side of the settling tank 30, and thus the inner When cleaning the contaminants accumulated in the upper surface of the inner tank 32, only the main cleaning can remove most of the large contaminant particles.

The storage tank 40 is configured to store water supplied from the settling tank 30 and the storage tank 40 by being embedded in a predetermined depth in the ground for a predetermined time.

The storage tank 40 has a storage tank 41 having a predetermined length up and down as shown in FIG. 5, and a storage tank which will be described later by using a pump 44 to store water provided on an upper surface of the storage tank 41. A supply pipe 42 for supplying to the side 50, and a discharge pipe 43 for discharging a predetermined amount of water through a sewer pipe (not shown) when the water stored in the storage tank 41 is filled to a predetermined level or more. .

The discharge pipe 31B of the settling tank 30 is connected to the other side of the upper portion of the storage tank 40, and the filter 45 having a predetermined thickness is formed in the internal space of the storage tank 41 between the discharge pipe 31B and the pump 44. Is installed, whereby only the water passing through the filter 45 is supplied to the reservoir 50 through the pump 44.

Herein, the filter may be one selected from a hollow fiber membrane filter or a reverse osmosis filter, or a hollow fiber membrane filter and a reverse osmosis filter may be used simultaneously.

The storage tank 50 is installed on the ground and is configured to supply and store water from the rainwater collection tank 20 and the storage tank 40.

As shown in FIG. 6, the storage tank 50 has a storage tank 51 in which a space is formed so as to store a predetermined amount of water therein, and an inlet port 52 provided at both sides of the upper portion of the storage tank 51. And an outlet 53.

A hole of a predetermined size (not shown) is formed in the upper surface, and a cover 54 covering the hole is provided in the upper portion thereof.

In addition, a pump 55 is installed in the storage tank 51, and the water stored in the storage tank 51 through the pump 55 is appropriately supplied for the purpose of living water used for crop cultivation or toilet bowl. Will be.

Here, the aeration device 60 may be further installed inside the storage tank 51 to prevent contamination of stored water.

The aeration device 60 is located in the inner lower side of the storage tank 51, as shown in Figure 7, the nozzle portion 61 is formed with a plurality of holes (not shown) radially along the outer surface, and Located in the upper portion of the nozzle unit 61 is a suction pipe 62 for sucking water above the nozzle unit 61 and supplying it toward the nozzle unit 61, and one end of the suction pipe 62 is connected to a high pressure It includes an air hose (63) for supplying compressed air of the air compressor (64) connected to the air hose (63).

When the high pressure compressed air is generated through the air compressor 64 and supplied to the suction pipe 62 by the above configuration, the high pressure compressed air is supplied to the nozzle unit 61 in the suction pipe 62 and discharged to the flow rate discharged. As a result, the water around the suction pipe 62 is sucked into the suction pipe 62, whereby numerous air bubbles are generated while being discharged to the outside through a plurality of holes in a state where the compressed air and the water of high pressure are mixed with each other.

At this time, the upper portion is opened between the nozzle part 61 and the suction pipe 62 to prevent air bubbles from immediately flowing back into the suction pipe 62 and to circulate the water stored in the storage tank 51 evenly. Guide member 65 is installed.

Air bubbles discharged through the nozzle unit 61 by the guide member 65 are guided upward of the storage tank 51 through the guide member 65, and the water at the upper side of the guide member 65 is suction pipe. As the number of air bubbles are generated while circulating below the guide member 65 through 62, the water is stored in the storage tank 51 to be contaminated as it is stored for a long time.

In addition, an ozone sterilizer (not shown) is further installed inside the storage tank 51, whereby bacteria and the like contained in the water may be sterilized.

As described above, in the present invention, the initial rainwater and the rainwater are separately stored, and the stored initial rainwater can be used for various purposes, such as crop cultivation or living water, because the contaminants are removed through several steps. Done.

In addition, it is possible to easily clean the contaminants accumulated in the initial excellent water tank, rainwater collection tank and sedimentation tank, so that the initial water and rainwater treatment capacity is secured for a long time.

In the above description, for the convenience of description, the preferred embodiments have been described with reference to the drawings and the components shown in the drawings. However, this is one embodiment according to the present invention. It should not be construed that the scope of the right should be construed, and that the simple substitution of a configuration having the same function as the change to the various shapes predictable from the description of the invention is within the range that can be changed by those skilled in the art. It will be very self explanatory.
