Description

Natural circulation tree filter box system

The present invention is a facility that can create a rainwater ecological storage facility to reduce the non-point pollutants generated in the impervious surface of the urban area, such as road area by using the urban infrastructure, it is possible to use the landscape trees, roadside trees, etc. that have been planted. In addition, it can be applied to the design of newly created urban areas, and after the installation of the facility, it can reduce the non-point pollutants generated in urban areas and roads, and the groundwater and soil storage rather than transferring the treated rainwater to sewer. The present invention relates to a natural circulating tree pollen filtration system with technology that helps to reduce peak flow rate and outflow volume, thereby solving groundwater exhaustion problems and preventing flood disasters.

Water pollutants that are unspecified in unspecified places according to urban development such as cities, roads, farmland, mountainous areas, and construction sites are called nonpoint sources of pollution due to urban development, and other pollutants such as industrial wastewater, livestock wastewater and other industrialized wastewater. In the case of the Han River region, about 30% of the pollutants generated are estimated by the Ministry of Environment. When such pollutants are treated through sewer pipes, existing facilities become larger than necessary, and when unspecified pollutants enter, it may be difficult to treat them.

Due to these problems, the Ministry of Environment is establishing multi-step measures to deal with non-point sources in three stages from 2004 to 2020. Currently, many companies are dealing with non-point pollution reduction technology. However, the conventional technology uses a point source treatment method such as industrial wastewater to discharge the non-point source generated quickly through the stormwater sewer pipe or storm pipe generated with the pollutant source, and water resource protection has been neglected.

In addition, due to urban development, the road paving rate is high (87.6% in Seoul, 2008), and it is difficult for rainwater to penetrate into the soil when it rains, and the amount is small even when it penetrates. Inundation of the city has to be walked and caused, and the damage caused by the economic and social losses, as well as the urban victims, is increasing over the years.

Therefore, it minimizes pollutant outflow loads at the same time and at the same time induces control of peak and total outflow during rainfall, and through this facility, non-point pollutants are treated to be close to the natural hydrological circulation structure before development. The objective is to minimize surface runoff, and to minimize the impact of pollution on nonpoint sources in discharged waters such as appeals due to nonpoint sources, rivers and sea areas.
These facilities may require technologies that minimize the size of the facility and preserve natural landscapes, reproduce their functions, and effectively reduce impervious surfaces.

Therefore, the present invention is designed to be installed in the basement by miniaturizing the non-point pollution reduction technology consisting of large units, and to process the rainwater to the groundwater by treating the treated rainwater in a natural circulation, the vegetation of the existing desolate urban environment in the ground portion Through the technology that can be transformed into a natural ecological space through the installation of facilities that can help improve the living environment of urban residents.

Due to urban development, the road paving rate (average paving rate of 87.6% in Seoul, 2008) is gradually increasing, and in the present situation where about 30% of all pollutants generated (estimated by the Ministry of Environment) is a nonpoint source, the existing nonpoint pollution reducing device Problems arising from the rapid rejection of rainfall runoff and large-scale engineering treatment concepts, namely damage to the natural environment resulting from the securement of large-scale treatment facilities, and increased loads and maintenance costs due to the inflow of unspecified contaminants. By treating the treated water (excellent) from the post-treatment process like industrial wastewater, the cost is increased, and the treated rainwater is sent to industrial infrastructure such as storm pipes and sewer pipes without being returned to nature. Increased runoff has caused secondary damage such as flooding and flood damage.

In order to solve the above problems, the natural circulation type wood pollen filtration system of the present invention is installed in areas where non-point pollution sources occur in urban areas such as parks and roadways, and the polluted rainwater is first passed through a screen to minimize contamination of media. In order to flow the rainwater that passed through the screen through the inlet, and to filter the rainwater slowly, the filter box was stacked with a wooden box with a water storage space that could be temporarily stored, and a filter filter that could exchange the stored rainwater. The pollutants contained are treated, and the treated rainwater flows back into the planting space and undergoes a process of natural purification through hardworking microorganisms.
Naturally purified rainwater is discharged to the ground through the rainwater discharge pipe or the lower discharge port, and the discharged rainwater is returned to the groundwater to become a natural circulation. In addition, the rainwater flowing into the natural circulation wood pollen filtration system of the present invention is designed to be introduced into the rainwater retention device through the rainwater connection pipe, and the rainwater flows in through the vegetation space of the wood pollen filtration system and the planting space of the rainwater retention device. The problem can be solved by applying a system with a structure that is naturally purified and returned to groundwater.
The existing patent, which is an eco-expandable tree box filter system for reducing road boiling point pollution, is similar to the natural circulation tree pollen filtration system, but the tree stream is installed on the side of the road and the rainwater flows through the inflow hole. It consists of a device that passes through the back drainage layer and discharges it through the catchment. This design is a modification of the filtration facility that processes the contaminated rainwater through the drainage layer, which causes problems such as poor performance when the incoming contaminants accumulate and clogging of the collecting holes. Problems may arise. In addition, because the media and vegetation soils are mixed when replacing the media, it is difficult to replace the media and there is no appendage space for freshwater drainage. There is no choice but to. Therefore, most of the rainwater generated is leaked to the outside, and the removal of nonpoint source around the road may not be smooth. In addition, the existing tree filtration non-point pollution reduction facility has the problem that it is difficult to replace the filter media by lifting the planted trees and replacing the media, and the replanted trees may die after the media replacement.

The natural circulation tree pollen filtration system of the present invention, which is a low impact development method, is a natural circulation tree that is activated with infrastructures such as flower beds, roadside trees, and ecological facilities, which are closely related to the existing living environment and easily seen from the surroundings. By replacing or improving the pollen filtration system and installing the minimum facility size for each section, it minimizes the pollutant outflow load according to the urban development and at the same time induces the control of the peak outflow and total outflow during rainfall. Through these facilities, non-point sources are treated so that they are close to the natural hydrological structure before they are developed. It is effective to maintain the rainfall-flow pattern of the state.

In order to achieve the above effect, a natural circulation type tree filtration system is installed in areas where non-point pollution sources occur in urban areas such as parks and driveways, and the polluted rainwater is first passed through the screen to minimize contamination of the media. Contaminants contained in rainwater through a filter box in which the rainwater that has passed through the rainwater flows in through the inlet to temporarily fill the rainwater, and the filter that stacks the media that can exchange the stored rainwater. The purified rainwater should be introduced into the planting space and install the system with the process of natural purification once again through the hardworking microorganisms. Some are discharged to the ground through storm drains or storm drains. Excellence is restitution to groundwater is a natural cycle.

In addition, the natural circulation wood pollen filtration system of the present invention can be used alone, but can be formed in a number of combinations with a plurality of natural circulation wood pollen filtration system, in this combined system is excellent through the excellent connection pipe excellent rain It is designed to be introduced into the retention device, and the rainwater that is introduced is purified through the filtration filter, and part of it can be the nutrient for plant growth through the planting space of the tree pollen filtration system and the planting space of the rainwater retention device. Contaminants can be achieved by applying a system having a structure in which the pollutants are naturally purified and the rainwater is returned to the groundwater.

Hereinafter, described in detail by the accompanying drawings an embodiment of the present invention as follows.

1 is a perspective view of a natural circulation wood pollen filtration system according to the present invention, Figures 2 to 5 are installation diagrams for each use, Figure 6 is a natural circulation wood pollen filtration system and rainwater retention device according to the present invention It is an installation view and a perspective view which showed the combination.

As shown in Figures 1 to 6 and representative diagrams, when rainwater occurs in the area where the non-point source of the city occurs, the initial rainfall of 5mm of rainfall after the rainwater having the highest concentration of pollutant is generated. Initial rainwater is collected and flows along the boundary of the roadway. Rainwater is discharged to sewer and stormwater according to the existing drainage system. The rainwater discharged in this way can not be returned to groundwater, resulting in groundwater depletion, and in some cases, the peak discharge can lead to secondary damage such as flooding. In order to solve this problem, the natural circulating wood pollen filtration system of the present invention installed at the boundary between the driveway and the sidewalk serves as a landscape by planting the upper part, and the underground part is equipped with a facility for treating polluted rainwater and draining it underground. have. As shown in FIG. 1, the natural circulation type of wood pollen filtration system of the present invention can represent the configuration of each component as follows. When rainwater occurs in a contaminated area, rainwater enters the inlet 11 of the crate 10. At this time, when a contaminant (garbage, etc.) enters the facility, since secondary pollution such as odor may occur due to anaerobicization in a closed space, a screen net 12 is installed inside the inlet 11 to easily remove the pollutant in advance. And the screen net 12 is easy to remove and easy to maintain.

The initial rainwater flowing into the inlet 11 is introduced into the water filling space 20 located between the wooden box 10 and the filtration filter 30, which does not secure sufficient fresh water space in the existing non-point pollution reduction facility. It is a method to solve the problem that only a small amount of initial rainwater is introduced and the rest is bypassed and discharged as there is no space for storage. The facility for efficiently removing substances and minimizing rainwater discharged by depletion of non-point pollution reducing facilities to maximize the discharge of rainwater to groundwater can be referred to as the appendage space 20 of the tree pollen filtration system of the present invention. .

The initial rainwater introduced into the appendix space 20 is contaminated with various pollutants such as tire dust, road dust, and heavy metals in the road, which occur in urban areas. The contaminant is reduced by passing through the filtration filter 30 filled with the filter medium 31 having an excellent effect of adsorption. Filtration filter 30 is a structure of a material that can be prevented from oxidation as a stainless steel square structure, and can put the filter media (31) by placing a laminated space inside the rim, and the stacked filter media (31) are packaged in individual packaging and easily It is composed of a structure that can be installed and dismantled, and the inside and outside of the filter filter 30 is provided with a filter perforated plate 35 so as to separate the vegetation soil 33 and the water filling space 20, the water filling space 20 and the compartment Was separated. Here, the filter medium 31 is a porous material used for filtration and is used for filtering or adsorbing impurities in water, and various kinds are used in existing water treatment facilities.
In the natural circulation type wood pollen filtration system of the present invention was used a pearlite or zeolite product having a good effect of filtration and adsorption of contaminants, this product has been proved effective in removing the pollutants and using ready-made products that can be easily purchased in Korea In the future, the tree protection plate 13 on the upper side of the wooden box 10 was opened to facilitate maintenance and replacement of the media 31. Non-point pollution reduction facility using such media (31) is a method that is widely used in existing facilities. However, the existing tree filtration facility that does not independently install the filtration filter 30 has a problem that the installation of the facility at the time of replacement of the filter medium (31) by placing the filter medium (31) in the lower part of the tree, If it is necessary to replace the filter medium 31, after lifting the wood to replace the filter medium may cause problems such as dead wood after replanting the lifted tree.
In addition, some conventional products are said to treat the pollution by installing wood chips, etc. on the top of the planting space 32 of the wooden box, the main functions of wood chips are to suppress the evaporation of moisture, to prevent ground erosion, to reduce the amount of sunlight transmitted As a suppression of the surrounding weeds, it is more meaningful as a landscaping material than water purification, and some of the roles of pollutants due to the growth of microorganisms are eliminated, but its role is insufficient.
In this way, the wood pollen filtration system of the present invention passes through the filtration filter 30 filled with the filter medium 31 rather than the conventional simple stacking method of the filter medium, and the rainwater is reduced in the vegetation soil of the wooden box 10 (33). ) Is partially absorbed in the planting space 32 is supplied to the tree or super-downstream planted in the planting space 32, and part is passed through the gravel layer 34, rainwater discharge pipe 14 shown in Figure 2 or the wooden box (shown in Figure 3) 10) is pitched underground through the lower outlet 15 of the lower back to the groundwater.
The lower discharge type shown in Figure 3 has been applied to a number of existing natural type non-point pollution reduction facilities, but the majority was a method of discharging the treated water by forming a plurality of holes rather than a fully open type. In this method, after a long time, the blockage of the hole proceeds and there is no leakage. In the tree pollen filtration system of the present invention, the bottom outlet of the wooden box 10 is applied by completely opening the lower part by applying the same method as planting a tree in nature to solve this problem.
The natural circulation wood pollen filtration system of the present invention having such a configuration can be independently installed, but excellent rain treatment can be used, but it is also possible to use a plurality of wooden boxes as shown in FIG. As it is possible to make a rainwater retention device 40 that can store rainwater in the middle of the wooden box 10, it is also possible to configure a complex system that can store and process a large amount of rainwater. In FIG. 6, the rainwater retention device 40 receives the rainwater that enters through the rainwater inlet 11 of the plurality of inlets 41a, 41b, and 41c and the wooden box 10. Some of the stored rainwater is supplied to the vegetation, such as the ultra-low stream planted in the planting space 44 of the rainwater retention device 40, and a portion of the rainwater stored in the wooden box through the rainwater connection pipe (44a, 44b) Inflow to the (10) is introduced into the appendage space 20 of the wooden box (10).
The rainwater introduced into the wooden box 10 is supplied to the wood planted in the planting space 32 of the wooden box 10, the rest is the lower outlet 15 or rainwater discharge pipe 14 of the wooden box 10 The rainwater is sent underground. As described above, the natural circulation wood pollen filtration system of the present invention is configured to circulate rainwater generated into groundwater through the wood pollen filtration system. The rainwater retention device 40 specified in FIG. 6 can be installed in an area in which the tree pollen filtration system of the present invention cannot be installed, or in an area in which flower beds are formed, by sufficiently securing the water filling space 42. Do. 7 is an exemplary view of a combination of a wooden box and a staying device, and a natural flower garden is formed by forming a flower bed at the top.
