In the drawings, FIG. 2 includes the A-A cross section of FIG. 1, but is not limited thereto. FIG. 3 also includes the B-B cross section of FIG. 1, but is not limited thereto.

As shown in Figures 1 to 3, the rainwater penetration and storage promotion device using the bottom-up filtration of the present invention is largely, the initial effluent separation device for separating and infiltrating the initial effluent, the filtration tank for filtration of the effluent and the filtered filtrate It consists of a reservoir for the storage of water.

The initial outflow separation device may be, for example, an inlet port 1, a filter network 2, an initial outlet control floating valve 3, an initial outlet reservoir 5, an initial outlet drain 4, an initial outlet drain valve 9. ) And an initial outflow separation tank (not shown).

The size of the initial outflow separation tank can be adjusted variably, and thus the initial outflow time and the initial outflow flow rate can be adjusted.

On the other hand, the filtration tank, when the outflow is continued beyond the set initial outflow flow rate, the effluent is introduced, the effluent water from the bottom of the filtration layer 6 from the bottom up as the level of the effluent is increased As a bottom-up filtration tank to pass through, the filter material of the filtration layer uses crushed stone and / or sand.

On the other hand, a penetration hole 8 is formed in the lower portion of the upward filtration tank to naturally penetrate the storage water in the filtration tank.

In addition, the filter of the filter layer 6 is injected by the washing water injected from the upper portion of the filter and drained to the lower portion of the filter, the washing water storage tank 12 for storing the washing water after the washing is provided, washing water after washing An upward filtration tank washing water drain valve 11 for controlling the inflow of the washing water storage tank 12 is installed, and an upward filtration tank washing water storage tank drain valve 10 for controlling the drainage of the washing water collected in the storage tank 12 is provided. .

Next, the stormwater permeation and retention promotion method using the bottom-up filtration according to the present invention will be described in detail with reference to FIGS.

First, the effluent including the pollutants and impurities in the watershed generated during the rainfall is introduced through the inlet (1) in the state containing the floating substances and impurities.

Among the impurities contained in the effluent water, the impurities having a large size and directly affecting the filtration are filtered out from the filter network 2.

That is, by effectively separating the impurities and other substances included in the outflow generated initially through the filter network (2) can minimize the impact on the water quality of the storage water.

Then, the effluent after passing through the filter net 2 is collected in the storage tank 5 of the initial outflow separator.

And, the outflow water collected in the storage tank (5) is sent to the initial outflow separation tank (not shown) by the operation of the initial outflow drain valve (9) through the initial outflow drain port (4), the initial outflow separation It penetrates into the basement underground (S1).

On the other hand, when the amount stored in the storage tank 5 reaches the operating range of the initial outflow control floating valve 3, the valve 3 is operated.

That is, if the outflow is continued in excess of the set initial outflow flow rate, the flow rate stored in the storage tank (5) correspondingly rises, and the initial outflow control floating valve (3) is operated by the rise, thereby The outflow amount of is introduced into the filtration tank including the upward filtration layer (6).

As described above, by controlling the size of the initial outflow separation tank variably, it is possible to control the initial outflow time and the initial outflow flow rate. Exclusion is possible.

The effluent flowing into the filtration tank passes through an upward filtration layer 6, in particular, an upward filtration layer 6 composed of aggregate and / or sand as the level of water gradually increases, thereby obtaining a water quality improvement effect. There is (S2).

As such, when the upward filtration layer which is responsible for the filtration function is composed of a multilayer structure of crushed stone and sand, maintenance is easy and economical. In particular, it is possible to effectively reduce the SS of runoff generated in the watershed, such as riverbeds and school grounds.

In addition, the upward filtration layer 6 is capable of washing the filter through a structure in which the washing water is injected from the upper part of the filter and drained downward.

After the washing is completed, the washing water is collected by a separate up filtration tank washing water storage tank 12 capable of storing the washing water by the up filtration tank drain valve 11, and the storage tank 12 by the up filtration tank washing water storage tank drain valve 10. Drain the wash water collected from).

As such, according to the structure in which the washing water is drained separately after the filter is washed downward in the upper part of the filtration tank, the filtration effect of the filter layer can be maintained for a long time, is easy to maintain, and minimizes the cost of maintenance such as the replacement cost of the filtration layer material. As a result, economic benefits can be expected.

On the other hand, the storage water in the filtration tank that is not filtered through the infiltration hole, which is a fine discharge hole located in the lower part of the upward filtration tank, penetrates into the basement at this time. Determine the natural penetration (adjustment of the area ratio of the penetration hole to about 0.5% or less), and make sure that the amount stored by the impact of the penetration hole is not affected during rainfall.

Therefore, if the rainfall period of 1 to 2 days is continued, the flow rate inside the upflow tank can be naturally drained, and the flow rate excluded by the discharge hole does not affect the storage amount because the flow rate is slow during rainfall. .

The filtered water passing through the upward filtration layer 6 is stored in the storage tank through the filtered water drain 7 (S3).

After the initial effluent separation process according to the present invention, the effluent containing the high concentration of pollutants generated during rainfall can induce continuous infiltration during the initial effluent separation process, and then, when the water level increases, that is, the effluent volume increases, the filtration tank In particular, it can be introduced into the bottom-up filtration tank to prevent the water quality of the stored water from being stored, and furthermore, if the outflow is continuously generated, infiltration and storage can be performed in parallel, so that it can be continuously infiltrated and stored from the outflow point. Do.

In particular, according to the present invention, it is excellent in reducing the SS, a water quality indicator that is a problem in runoff from riverbeds and sports grounds consisting of soil, and initial rainfall occurring in watersheds with large pavement areas in urban areas. It is highly useful because it can separate and handle the pollution degree contained in.

According to the present invention, the groundwater level and the utilization of the reservoir channel are secured by infiltrating and storing the excellent runoff water generated in the area where the main material of the watershed, such as the river site and the school ground, is composed of soil and the area where the runoff is concentrated in general urban areas. Can be enabled. In addition, according to the present invention there is a good construction and economical properties of the material required.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Therefore, the scope of the utility model registration claims attached will include such modifications or variations that fall within the spirit of the present invention.
