Description

Vegetation filtration system for early excellent treatment {Vegetative Filter For Primary Stage Rainwater Treatment}

The present invention relates to a vegetation filtration device for the initial excellent treatment, more specifically, by reducing the non-point pollution in the initial rainwater discharged from the road by using the side roads, central separation space, etc. The present invention relates to a vegetation treatment device for initial excellent treatment that does not require an installation space and can also help urban landscapes.

In particular, since the non-point pollutants included in the initial rainwater are filtered through the laminated filtration layer by stacking different materials to form a filtration layer, the initial rainwater treatment for preventing the pollution and contributing to the restoration of rivers and ecosystems It is about a vegetation filtration system.

In addition, the present invention relates to a vegetation filtration apparatus for initial excellent treatment, which is formed in a simple structure, which can reduce manufacturing and installation costs, and is easy to maintain and maintain by configuring two types of covers, distribution plates, and filter cases.

In general, sources of water pollutants can be classified into point sources and nonpoint sources. Point sources are continuously generated at a certain point such as domestic sewage, factory wastewater, and industrial wastewater. Non-point pollutants are pollutants that are discharged along with surface runoff during rainfall, while rainfall and rainfall in urban areas, fertilizers and pesticides applied to farmland, soil erosion, barn spills, and atmospheric drops. It means water, etc., and it flows out in a wide area.

These non-point pollutants are difficult to artificially control because of the large seasonal variation in emissions, difficult prediction and quantification, and being affected by weather conditions, terrain, and geology. In pollutant management and reduction, many pollutants have been reduced due to the development of treatment methods and construction of new sewage and wastewater treatment plants.However, methods and equipment for non-point pollutants are still insufficient. It is a reality that it is difficult to improve the water quality only by treatment-oriented water quality policy alone.In addition, due to the increase in the impermeability rate of the region, urban runoff characteristics change due to urbanization, and in terms of water quality, various pollutants are discharged into the water system along with the runoff water. Since it is a cause of water quality deterioration, active management of stormwater runoff is needed to improve the quality of rivers and lakes caused by nonpoint sources.

In addition, once non-point pollutants enter the surface or groundwater, it is difficult to manage them.Non-point pollutant treatment increases the processing cost and becomes more difficult as it is farther away from the pollutant. It is preferable to apply, but the conventional non-point pollutant treatment has a problem in cost and efficiency in the manner of collecting and treating contaminants at the end of the drain pipe.

In addition, LID (Low Impact Development) techniques have recently emerged to reduce nonpoint pollution. Since the introduction of the non-point source installation notification system in June 2012, a total of 322 development projects and workplaces have been reported to install nonpoint source sources. In March 2008, the Japanese survey highlighted problems such as maintenance and efficiency of non-point pollution reduction facilities. As a result, the necessity of research and research on the nature-friendly management method for the management of nonpoint source has increased. Especially, the LID technique that utilizes natural materials such as soil and stone and the penetration function for the management of nonpoint source is emerging. to be.

In order to solve the problems described above, a device for treating non-point pollutants of the initial excellent water has been proposed. In the Republic of Korea Patent Publication No. 10-0605267 "water treatment device" is discharged to the river through the sewage pipe, etc. A rainwater treatment device for separating contaminants from rainwater, which employs a structural separation system that combines swirl and filtration in a single device, with sediment deposited at the bottom of the device rising to form vortices. In order to prevent the re-injury of the sediment, which is a disadvantage of the swirl method, by applying the anti-floating means, the filtration tank equipped with the filtration means is separately installed to separate the vortex and the laminar flow forming tank capable of forming the laminar flow. Maximize the treatment efficiency of the bed, especially the flow path leading to laminar flow formation, and the laminar flow forming vessel disposed in the flow path It is proposed to form a boundary layer that blocks the mixing of vortices and laminar flows through the floe to block the sediment that rises along the flow path.

Such "excellent treatment device" is a complicated and difficult structure because the installation of the swirl method and the filtration method in the device, the rainwater that is introduced because it is the structure that is discharged by filtration as the rainwater that is initially introduced from the bottom gradually to the top. If it is less, rainwater flows into the device as it is, so rainwater is contaminated and there is a problem of environmental pollution due to odor.

Republic of Korea Patent Publication No. 10-0751534 "Continuous sedimentation filtration initial excellent treatment device" in the cylindrical shape is formed in the tangential direction of the inlet pipe communicating with the storm conduit, vortex flows into the inlet pipe to rotate the initial rain Joe; The outer periphery is formed to be inclined downward, and is fixedly installed through a plurality of flanges around the inner surface of the vortex tank, and the sedimentation material contained in the initial excellent water is formed through the precipitation guide formed by the inner circumference of the vortex tank and the outer circumferential portion of the vortex tank. A cone-shaped precipitation induction plate for inducing precipitation to cotton; A partition wall installed at an upper portion of the vortex tank and having a plurality of micropores formed therein to prevent the rise of precipitated material and allow the initial excellent water to pass therethrough; A filtration tank provided with a filtration layer for filtering excess precipitate and organic substances included in the initial excellent water passing through the partition wall; And an outlet for discharging the initial excellent water passed through the filtration tank to the outside.

Such a device is constructed by installing the vortex tank and the filtration tank at the same time, and there is a difficulty in maintenance and repair, and the device that the rainwater flows in is small because the rainwater that is initially introduced is gradually filtered from the lower part to the upper part. Rainwater introduced into the remains as it is there was a problem that the rainwater is polluted environmental pollution due to odor.

Accordingly, the present invention proposed to improve such a conventional problem is to apply the LID technique technology elements, which are emerging recently, to reduce the non-point pollution in the initial rainwater discharged from the road by using the side roads, median space, etc. It is to provide a vegetation processing device for a new type of initial excellent treatment that can help the landscaping of the city by not requiring a separate installation space by utilizing the existing space.
