Description

Stream type current circulation system and stream type current circulation management method {WATER FLOW SYSTEM AND WATER FLOW MANAGEMENT METHOD FOR RIVER}

The present invention relates to a water flow circulation system and a water flow management method in urban or urban streams, and more particularly, it is possible to increase the water resource circulation rate through efficient management of river maintenance water in the feng shui and dry season, and comfortable around the river. The present invention relates to a stream water flow circulation system and a water flow circulation management method capable of providing a hydrophilic space and a landscape space.

Most of the small and medium rivers in Korea have a large elevation difference in the upper part of the river, so the waterway slope is urgent, resulting in massive flooding due to the problem of securing the stream maintenance, which is the minimum flow rate required for the dry season, and the instantaneous discharge of river water during the flooding. There was a problem that caused damage.

In order to solve this problem, a water gate is formed in a stream, and the water is normally trapped so that a certain amount of water flows in a state in which a certain amount of water is trapped. Can be moved quickly.

However, since this is merely blocking the water for the beauty of the river, it does not control the flood control or the amount of water flowing through the river, but simply traps the water. Because of this, if there is no quantity of water and little water flows, fallen leaves, etc. accumulate on the bottom of the river, obstructing the flow of water, and the water does not flow and decays while standing in the river without supplying oxygen to the water. The accumulated sediment will decay over time, causing the water of the small rivers to die.

On the other hand, pollutants generally include point pollutants emitted from a defined and limited point source such as domestic sewage, industrial waste and livestock waste, agricultural land, grassland, forest land, construction sites, mines, logging sites, and wastes. Discharge areas can be divided into nonpoint pollutants emitted from a wide range of nonpoint sources, such as treatment plants, landfills, urban areas, roads and industrial sites.

Contaminants emitted from such pollutants are distributed in a wide variety of forms, including heavy metals, pathogenic microorganisms, organic compounds, radioactive materials, toxic substances and other salts.

These pollutants are usually swept away by rainwater and run into public waters and groundwater such as rivers, bays, lakes, and lakes, causing water pollution, and eventually destroying ecosystems. It is very damaging.

In case of point pollutants with a clear discharge point among these pollutants, a separate purification device or wastewater treatment facility is installed in homes, factories, livestock farms, etc., but some of the pollutants are purified. Not only is the discharge area wide, but also remains mostly on the surface of the earth, and it is the main cause of water pollution as it enters public waters or groundwater such as rivers, bays and lakes with rainfall during rainfall.

Therefore, in the past, apparatus type facilities or simple storage facilities are used to purify contaminants contained in rainfall runoff, but the cost is inferior to the treatment cost, and it is necessary to replace the system regularly. There was a downside to this being exhausted. In addition, the conventional facilities have most limitations on the stability and efficiency of treatment compared to the facilities, and are mainly piloted in very limited places such as large buildings, roads, and parking lots. There are limitations to treat rainfall runoff with various sources of pollution.

In addition, conventionally, some purification facilities are installed at riversides to treat water. However, these purification facilities are not only applicable to various pollutants because they are composed of layers of gravel and sand to remove the surface of rivers and to purify them. There is a problem that (gravel layer, sand layer) and the like are closed by soil. In addition, since a single ecosystem is formed by a single vegetation, such as grass, after covering the upper part, it is not in harmony with the river ecosystem and causes disconnection with the land ecosystem. Areas formed of such single ecosystems require excessive erosion during flooding, sedimentation and scour due to soil erosion, and require repairs by section. This problem is bound to be limited.

Korean Utility Model Registration Application No. 2004-21160 describes a "Backflow Purification System for Treating Effluents in River Water, Lake Water, and Wastewater Treatment Plant." This technology is designed to excavate a portion of a river's blisters and then stack several layers for purification, where the purified water flows along the surface and discharges into the stream. However, this technique also has the same problem as above.

Most rainfall runoff (non-point pollutant) treatment facilities currently being developed or applied have limitations that are used only during rainfall.In the case of facilities that directly purify existing river water, normal operation of the treatment facilities during rainfall As an impossible situation, its use has limitations.

Therefore, in order to achieve various purposes such as water supply, flood prevention, and hydrophilic space creation through rainwater management, we actively utilize small rivers where rainwater collects and flows around the city or downtown, along with management of rainwater quality. In connection with this, research is needed to develop watersheds and dimensions of rainwater, recycle water resources, and develop effective measures and systems in feng shui and dry seasons.

Therefore, the present invention has been proposed to solve the above-mentioned problems, and in the feng shui season to store in the storage tank, and in the dry season to be used as ecological maintenance water and landscaping water of the river to ensure continuous and efficient management of river water The purpose of the present invention is to provide a stream type water circulation system and a stream type water circulation management method that can increase the water resource circulation rate.

Pumping through pumping means to utilize as one; Supplying the necessary power to the filtration unit and the pumping means by at least one of a photovoltaic device or a wind turbine.

In the pumping step, it is preferable to detect and pump the level of the river and the level of the irrigation channel.

The permeable sidewalk block may have a storage space in which rainwater can be stored. In addition, in the water flow circulation management method of the present invention may be configured to back convey the rainwater stored in the storage tank to the water-permeable sidewalk block through the transfer pipe member.

In addition, inducing stormwater into the ground in the stream-type water flow circulation management method of the present invention reduces the inflow of the river during flooding, especially as the amount of penetration through the permeation block unit increases. In addition, the storage of rainwater in the storage tank secures the amount of storage during the feng shui season, and can also be utilized as the maintenance water for river maintenance or irrigation during the dry season, thereby increasing the water resource circulation rate and maintaining the river ecological environment.

The applicant of the present invention describes the theoretical simulation performed to predict the water circulation performance in the case of having the permeable sidewalk block (particularly the permeable sidewalk block of the second embodiment) according to the stream-type water flow circulation system described above. .

In this simulation, since the drainage performance of the water permeable sidewalk block of the present invention is almost an open space, there is no problem in the drainage of rainwater, and the amount of water in the grid space (repair space) stored by the eco-friendly superabsorbent composite ( Atmospheric water circulation performance was predicted against seasonal evapotranspiration of 480cc / 0.01㎡ (unit block 1EA).

The basic data of this simulation is as follows.

◆ Repair amount per block 1㎡ of the present invention = Repair amount of one block x 100

                                        = 480 cc / 0.01㎡ × 100

                                        = 48,000 cc / ㎡

                                        = 48 mm / m2

◆ Weather information for summer streams in downtown Seoul (July average) (Korea Meteorological Agency statistical data: 1971-2000 average)

Average temperature = 24.9 ℃, ground temperature = 26.8 ℃, average humidity = 79.8%, precipitation = 10.5㎜

Precipitation time = 126.7 Hr, evaporation rate = 3.6 mm, wind speed = 2.3 m / sec

◆ Weather information for spring and spring seasons in downtown Seoul (April and October averages) (Korea Meteorological Agency statistical data: Sang-dong)

Average temperature = 13.3 ℃, ground temperature = 14.1 ℃, average humidity = 62.8%, precipitation = 2.3mm

Precipitation time = 50.6Hr, evaporation rate = 3.2mm, wind speed = 2.5m / sec

The latent amount of evapotranspiration (ET0) is calculated by the following [Equation 1].

[Equation 1]

Latent Evaporation (ET0) = Kp × Epan

Where ET0 = latent evaporation (mm / day)

            KP = evaporation factor

            Epan = evaporation of the evaporator (mm / day)

At this time, the regression equation of the evaporation coefficient (Kp) of the non-greenery as in the road is as shown in [Equation 2].

&Quot; (2) "

Kp = 0.61 + 0.00341 × average relative humidity-0.000162 × wind speed × average relative humidity-0.00000959 × wind speed × buffer distance + 0.00327 × wind speed × Ln (buffer)-0.00289 × wind speed × Ln (86.4 × wind speed)-0.01061 × Ln ( 86.4 × wind speed × Ln (shock distance) + 0.00063 × (Ln (shock distance)) ² × Ln (86.4 × wind speed)

At this time, the buffer distance of the road is usually calculated as 50m.

The results of calculating the evaporation coefficients (Kp) by substituting weather data of summer and spring in [Equation 2] are as follows.

Summer Evaporation Coefficient (Kp) = 0.676902

Spring evaporation coefficient (Kp) = 0.619376

Subsequent calculations of latent evaporation (mm / day) for each of the summer and spring evaporation coefficients and meteorological data calculated in [Equation 1] are as follows.

Summer latent evapotranspiration = 0.676902 × 3.6 = 2.44 mm / day

Spring latent evapotranspiration = 0.619376 × 3.2 = 1.98 mm / day

Therefore, the permeable sidewalk block has 48mm / m2 of rainwater storage in rainy weather, and the water circulation is maintained at about 19.6 days in summer and 24 days in spring, considering seasonal potential evapotranspiration. It is thought that it will be possible to achieve heat island mitigation.

In conclusion, the present invention is excellent in preventing rainwater spillage by increasing the amount of rainwater supply to the ground while relieving the inconvenience of walking on the sidewalk in rainy weather due to its excellent rainwater permeability, and at the same time, it has high water absorption in the block. It was confirmed that it is a water circulation system with water storage system capable of circulating water to the atmosphere for about 20 days with the function of reducing the non-point pollution by the polymer composite.

According to the river water flow circulation system and the water flow circulation management method according to the present invention configured as described above, when the water flows in the fresh water in the storage tank in a clean state after the treatment process, and then when the water in the reservoir It can be used as ecological maintenance water and landscape water for rivers.

In this way, when the water is discharged, the water of the storage tank is discharged and discharged upstream to satisfy the level of the river. When the river level is satisfied, the discharged water flows to the waterside such as an irrigation channel formed near the sidewalk through a pumping means by the detection of a water level sensor or a water head detection sensor, or through an associated flow path by the water head. It is possible to create a space and to provide a hydrophilic space for simple foot soaking.

In addition, the present invention ecological maintenance water and landscaping water used during the dry season can be reused continuously except the loss by evaporation, etc. after joining the system downstream from the stream. The reason for such reuse is that the water can be reused through the process of re-introducing the water through the transfer pipe and removing the pollutant of the water.

In addition, the present invention can effectively manage the rainwater through the streams around the city, urban streams, or artificial parks or artificial rivers in the city, and the depletion of groundwater by linking with the storage facility unit that suppresses the runoff of rainwater and stores the rainwater Prevents and efficiently floods and drains rainwater, thereby increasing the rate of water circulation.

In addition, the present invention basically eliminates the inconvenience of using walkways around the river to maintain separation even when the ground subsidence combined with the water permeation function, and the water evaporation and the ground water to be released into the atmosphere through the capillary phenomenon By constructing a permeable block unit to provide a comfortable walkway and heat island mitigation function in urban streams. Herein, the present invention prevents re-injury of sediment settled on the bottom surface through rainwater storage unit of characteristic configuration, thereby reducing pollution of rainwater discharged, and prevents bacterial growth due to algae or bacterial contaminants contained in rainwater. Can inhibit or eliminate bacteria.
