In this way, the pollutants leaked from the catchment surface of the building or the air are transported to the drainage by rainfall, and then flowed into rainwater or sewage receiving, and then discharged to sewage pipes.

In this case, when the sewage system is a confluence type, contaminants are introduced into the sewage treatment plant and treated, but when the contaminants introduced into the sewage system include heavy metals, a separate treatment means for removing them is required. There is a problem that is a big burden for sewage treatment.

In addition, sewage discharged from homes or factories is introduced into the sewerage system as well as the drainage of the building, and the sewage is further increased in the sewage treatment apparatus because the pollutant is contained therein.

On the other hand, when the sewage system is a classification, the pollutant is not treated, but is introduced into the surrounding water as it is, and thus the pollutant flowing into the water causes eutrophication or acts as an endocrine obstacle and adversely affects the ecosystem. There is a problem that causes various water pollution, such as itch.

Accordingly, the present invention has been proposed to solve the above problems, and collects various pollutants deposited on the building catchment surface by rain with rain water, and absorbs or filters the pollutants by using a mat. Excellent drainage treatment system and treatment method for removing floating pollutants contained in building drainage by filter media to reduce burden on sewage treatment and reduce water pollution caused by inflow of pollutants The purpose is to provide.

Looking at the detailed configuration of the building storm water drainage treatment device, as shown in Figure 1, the rainwater inlet 110 is formed on the upper side and the rainwater outlet 120 is formed on the other side of the rainwater Receiving tank 100; The rainwater tank 100 is provided at the upper side and flows only to the lower side of the rainwater tank 100 when the rainwater flowing from the inlet 110 is less than a predetermined amount, and thereafter divided into the upper and lower sides when the rainwater increases. A cover 200; A first partition member 300 extending downward from one side of the cover 200 to partition the rainwater flowing from the inlet 100 to the lower side at the bottom; And a second partition member 400 extending downward from the other side of the cover 200 so as to partition the rainwater flowing from the first partition member 300 at the bottom thereof. And a contaminant treatment means 500 provided between the first compartment member 300 and the second compartment member 400 to remove contaminants from the influent water therethrough.

Here, the porous plate member 600 is further provided on the upstream side of the pollutant treatment means 500 along the rainwater flow direction and partitioned with a plurality of through holes 610 to allow rainwater to flow therethrough.

The rainwater container 100 is formed to be inclined so that its bottom portion is increased along the flow direction of the sewage, and further includes a recessed portion extending to the outer lower side of the maintenance tank 310 to be described later.

In addition, between the second compartment member 400 and the storm water container 100 is further provided with a contaminant filter adsorption means 700 for removing the contaminants.

Therefore, a maintenance tank 310 is formed between the one side portion of the rainwater container 100 and the first compartment member 300, and between the first compartment member 300 and the second compartment member 400. The treatment tank 410 is formed, and the filling tank 710 is formed between the other side portion of the rain water receiving tank 100 and the second partition member 400.

The cover 200 may be detachably installed.

In addition, the contaminant treatment means 500 is a porous material made from a fibrous material extracted from wood, and has a mat shape capable of removing not only floating solids but also organic contaminants and heavy metal contaminants.

In addition, a specific functional group may be applied to the surface of the mat-shaped contaminant treatment means 500 in order to increase the treatment efficiency for the contaminant. The pollutant treatment means 500 may be installed perpendicular to the direction in which the inflow water is supplied, or may be installed in an inclined form.

Contaminant filtration adsorption means 700 located in the filling tank 710 is made of a mesh cloth having a predetermined mesh (mesh), the inside is filled with a filter medium for removing the contaminants by filtration or adsorption. As the filter medium, a material having high adsorption of hydrophobic substances and the like and easy to disturb disturbance cleaning and light specific gravity, for example, fine pieces of expanded polypropylene, and the like, in addition to activated carbon, loofah, mosquito net and ring race ) And the like can be used.

The outlet 120 through which the rainwater flowing to the upper side of the cover 200 is discharged, and the rainwater flowing from the filling tank 710 is discharged from the pollutant treatment, is flush with the inlet 100 of the rainwater receiving tank 100. It is provided to be positioned below, so that the discharge of the treated water is made naturally, taking into account the frictional loss of each portion of the flow path to the outlet 120.

In this embodiment, in order to form the maintenance tank 310, the processing tank 410 and the filling tank 710 of the rain tank 100, each of the predetermined components using a connecting pin or a metal connecting mechanism. The structure is integrated into a rectangular or circular shape, but the maintenance tank 310, the treatment tank 410 and the filling tank 710 of the rain water tank 100 can be formed in one tank It is a fact of the vagina.

The outlet 120 is connected to a drainage passage 122 for draining the drain pipe or artificial wetland 121 buried around the building.

In the storm water receiving tank 100, it is preferable that the block for forming the maintenance tank 310, the treatment tank 410 and the filling tank 710 is made of a block made of concrete, which is a drainage treatment device In order to facilitate the construction and shorten the construction period.

Here, the storm drainage treatment apparatus according to the present invention may not have a passage for guiding the inflow of water to the upper side. In other words, the maintenance tank 310 is installed in the storm water drainage conduit of the building, and has an inner space with an open top; A treatment tank 410 partitioned from the maintenance tank 310 by a first partition member 300, the lower portion communicating with the maintenance tank 310, and having an inner space having an upper portion open; A filling tank 710 partitioned from the processing tank 410 by a second partition member 400, the lower part communicating with the processing tank 410, and having an inner space having an upper portion open; A mat (500) mounted in the treatment tank (410), which is a pollutant treatment means for first removing contaminants contained in the contaminated water passing through the treatment tank (410); Contaminant filter adsorption means (700) mounted in the filling tank (710) and filled with a medium for filtering and adsorbing contaminants contained in the contaminated water passing through the mat (500); And a cover 200 for opening and closing the maintenance tank 310, the processing tank 410, and the opening of the filling tank 710.

Referring to the building excellent drainage treatment apparatus according to the present invention configured as described above are as follows.

Particles contained in the exhaust gas generated by the driving of auto bodies, especially diesel engine cars, and environmental pollutants such as dust, factory smoke, dust, etc. due to abrasion of asphalt, first due to abrasion of tires When the water is deposited on the surface and is carried by drainage through rainfall to reach the side opening, the contaminated water including the contaminant is introduced into the maintenance tank 310 through the inlet 110 of the water well tank 100.

The contaminated water introduced into the maintenance tank 310 passes through the lower side of the first partition member 300 and passes through the pollutant treatment means 500 of the treatment tank 410 through the porous plate member 600. do.

The pollutant treatment means 500 primarily filters and removes various environmental pollutants such as organic pollutants and heavy metal pollutants, as well as floating solids contained in the contaminated water.

The treated water treated by the pollutant treating means 500 passes through the filling tank 710 to remove contaminants by filtration or adsorption by the media filled in the pollutant filtering adsorbing means 700 of the filling tank 710. .

The treated water passing through the filling tank 710 is drained to the drain pipe or artificial wetland 121 through the drainage passage 122 through the outlet 120 of the rainwater receiving tank 100.

Solids such as sand or mud that do not pass through the contaminant filtration adsorption means 700 of the filling tank 710 in the series of wastewater treatment are precipitated on the bottom surface of the filling tank 710, and the Solids removed from the contaminant treatment means 500 are also precipitated on the bottom surface of the treatment tank 410. At this time, contaminants are adsorbed to the precipitated solids such as sand or mud, and the solids adsorbed to the contaminants flow down the inclined bottom surface of the rainwater receptacle 100 to the maintenance tank 310. It enters and deposits in the deposit.

Briefly referring to the operation of the storm drainage treatment apparatus of the present invention, the pollutants deposited on the catchment surface of the building are sequentially transported by the building drainage according to the rainfall, for example, when there is a rainfall of about 5-14 mm. Almost all of the water flows into the drainage system. At this time, after the rainfall is introduced into the maintenance tank 310, the rainfall is introduced into the treatment tank 410, the contaminant removal process is properly performed in the treatment tank 410, if the rainfall continues after that In the building drain with a low content of pollutants flows into the maintenance tank (310).

As such, it is necessary to effectively carry out the pollutant removal treatment in the initial rainfall stage. For this reason, the volume of the flow path including the maintenance tank 310 and the treatment tank 410 of the present invention can continue to flow into the building drain while discharging the treated water through the outlet 120 at least in the initial rainfall stage. Is set.

By the way, when there is a lot of rainfall per hour, the maintenance tank 310 is filled with inflow water during the rainfall, the building drainage may not be able to flow in, in this case, excess water (14mm or more) is covered ( It flows on the upper side of the 200 and is discharged directly from the outlet 120.

Since the waste water discharged in this way does not pass through the treatment tank 410 and the filling tank 710, the pollutant removal process is not performed. However, since the removal process of the pollutants deposited on the catchment surface of the building by the storm drainage treatment is almost completed in the initial rainfall stage, the amount of the pollutants in the building drainage by the subsequent rainfall is small. Therefore, the subsequent drainage is discharged immediately without passing through the pollutant treatment means 500 or the pollutant filtration adsorption means 700, and the drainage having almost no pollutants is discharged.

On the other hand, by setting the volume of the flow path large, it is possible to discharge all of the building drainage through the pollutant treatment means 500 and the pollutant filter adsorption means 700 even if the rainfall is large. This increases the difficulty in terms of installation space and construction costs.

Therefore, in the present invention, the removal of contaminants is actively performed for the building drainage during the initial rainfall stage with a high content of contaminants, and some of the contaminants are considered in consideration of the low content of contaminants for the subsequent building drainage. It is configured not to pass through the treatment means 500 and the contaminant filtration adsorption means 700, thereby miniaturizing the entire apparatus and reducing the construction cost.

In addition, in this embodiment, since the cover 200 is in the state which partially shielded the upper side of the maintenance tank 310, the said maintenance tank 310 is filled with inflow water, and the outflow excellent in a building is more excellent. When the abnormality does not enter, excess water flows through the upper surface of the cover 200. Therefore, there is no fear that the contaminated water in the maintenance tank 310 is agitated, and the sediment deposited on the lower portion thereof is swept up and discharged.

If the contaminant removal process is continued as described above, the sediment containing the contaminant is deposited in the bottom of the treatment tank 410 and the filling tank 710 to the bottom of the maintenance tank 310. For this reason, it is necessary to perform maintenance and repair regularly. In this case, first remove the cover 200, and then observe the deposition state of the precipitate through the opening of the maintenance tank (310). When it is determined that the deposit needs to be removed, a separate suction tube (not shown) is put into the maintenance tank 310 to suck and remove the precipitate by the suction action of the suction tube.

When removing the contaminants deposited in the treatment tank 410 and the filling tank 710 without moving to the maintenance tank 310, the pollutant treatment means 500 and the pollutant filtration adsorption means 700 is removed. After the separation from the treatment tank 410 and the filling tank 710 to the outside, a suction tube (not shown) is introduced to suck and remove by the suction action of the suction tube. In addition, the separated pollutant treatment means 500 and the pollutant filtration adsorption means 700 may be cleaned, and again installed in the treatment tank 410 and the filling tank 710 to resume the pollutant removal process.

Brief description of the storm drainage treatment method by the storm drainage treatment device as described above is as follows.

First, the first step of the initial excellent inflow into the rainwater tank having an inlet and outlet for the rainwater inflow and outflow on both sides; A second step of guiding the initial rainwater flowing into the lower side of the rainwater container; A third step of sequentially removing various environmental pollutants contained in the rainwater guided to the lower side of the rainwater container according to the flow progress direction of the rainwater; And a fourth step of discharging the contaminant-treated water to an outlet of the storm water tank.

Here, the fifth step of discharging a part of the rainwater through the upper side of the rainwater tank to the outlet when the rainwater flows into the lower portion of the rainwater tank after the initial rainwater flows in the second step; It may further include.

In addition, the third step, the sixth step of removing the suspended solids, organic contaminants and heavy metal contaminants through a porous material made from a fibrous material; And a seventh step of forming a mesh cloth having a predetermined mesh and filtering and adsorbing the contaminants through a material filled with a medium for removing the contaminants by filtration or adsorption therein.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

As described above, the building drainage treatment apparatus and treatment method according to the present invention can reliably handle the reduction of pollutants including heavy metals in the combined sewerage system, thereby reducing the burden on sewage treatment, and In the food sewage system, pollutants can reduce various water pollution which adversely affects the ecosystem, such as eutrophication or endocrine obstruction.

In addition, the present invention, the removal process of the pollutants contained in the initial rainwater is mostly completed in the initial rainfall stage, and since the amount of pollutants in the building drainage due to the subsequent rainfall is reduced to a minimum amount, the direct discharge By setting the volume of the maintenance tank, treatment tank, and filling tank to a minimum, it is possible not only to miniaturize the entire storm drainage treatment apparatus, but also to reduce the installation space and to reduce the construction cost.

In addition, the present invention, since the cover partitioning the upper and lower parts of the rain water tank is detachably provided, there is an effect that can easily identify and remove the precipitated state precipitated on the bottom of the rain water tank.

In addition, the present invention is installed on the lower side than the inlet so that the treated water from which the contaminant has been removed can be naturally discharged from the outlet, thereby simplifying the discharge of the treated water without using a pump or the like. have.

In addition, the present invention, the contaminant treatment means for removing the contaminants and the contaminant adsorption filtration means is installed detachably, there is an effect that can be easily cleaned or replaced.
