The present invention includes an excellent collecting step (S 210) for receiving an initial storm containing non-point pollutants accumulated on the road surface or a road surface of a bridge or the like in the first manhole (110).

When rain is concentrated in a city or a city near the city in a short period of time, the rain containing the nonpoint pollutant accumulated on the road surface of a road or a bridge or the like flows into the surrounding manhole in the initial rainfall.

The present invention includes a first manhole 110 for collecting such initial storms.

The first manhole 110 is constructed of a first manhole 110 and a second manhole 110. In the first manhole 110, non-point pollutants such as dust accumulated on a roadside during a rainfall, vehicle exhaust gas, fine dust such as a tire, (112). Since the initial rainwater necessarily contains non-point pollutants, it is necessary to filter such non-point pollutants.

The present invention includes a primary filtration step (S 220) of initial rainfall in order to separate non-point pollutants in the initial rainfall from the first manhole (110) and move to the next step.

The primary filtration step (S 220) of the initial rainfall proceeds inside the first manhole (110). The initial rainfall that has entered the entrance 112 of the first manhole 110 drops downwardly after passing through the manhole 114 installed inside the first manhole 110. The strips 114 are primarily filtered by separating various leaves, paper, vinyl pieces, and other wastes contained in the initial rainfall.

The screen 114 divides the screen into a first storeroom 113 and a second storeroom 115. The initial storages which have not yet been filtered are collected in the first storeroom 113 divided by the strips 114 while the leaves are firstly filtered in the second storeroom 115 It is the part where the removed primary filtration excellence is filled.

It is preferable that the pull string 114 is installed in a detachable manner in order to be used in accordance with the use state of the first manhole 110. The first storey 113 and the second storerob 115 are separated from each other in the same first manhole 110 to form respective storage spaces. It is preferable to form the vertical filtration part 114a and the inclined filtration part 114b so that all the rainfall can be filtered. In the first storeroom 113, the non-point pollutant tends to increase as time passes. However, the change in the content of the non-point pollutant does not significantly change with time in the second storeroom 115 .

The second storeroom 115 receives the first filtered storm with relatively initial non-point pollutants removed and has a state before being transferred to the second manhole 130.

As the rainfall continues, the second storeroom 115 is gradually filled with fresh clean water, so it is necessary to discharge the first filtered storm to the outside. This need may be accomplished through the metrology sensor 116. The rainfall measuring sensor 116 senses a predetermined position while gradually rising from the bottom surface to allow the pollution isolation pipe 120 to start operating.

The present invention separates the heavy pollutants in the first filtered well in the process of transferring the first filtered wells from the first manhole 110 to the second manhole 130, Return to the manhole 110, and a second stage of filtration (S 230), which transports the second filtered wells with heavy contaminants removed to the second manhole.

The transfer and secondary filtration step (S 230) of the stormwater is performed in the first stage of filtration, in which leaves, paper, vinyl paper, and nonwoven fabric pieces having large or large surface area are removed from the initial rainfall.

It is preferable to use the pollutant separation pipe 120 installed between the first manhole 110 receiving the initial rainfall and the second manhole 130 connected thereto Do.

The pollutant separation pipe 120 connects the first manhole 110 and the second manhole 130 and transfers the rainwater of the first manhole to the inside of the second manhole 130, And simultaneously performs a function of secondly filtering out heavy contaminants contained in the inside.

The pollutant separation pipe 120 connects the first manhole 110 and the second manhole 130 so that the rainwater existing in the first manhole 110 can move to the second manhole 130 Which is embodied in the form of a cylindrical tube or a square or hexagonal tube whose exterior is closed and whose interior is hollow.

The pollutant separation pipe 120 is connected to the upper surface of the second manhole 130 from the bottom surface of the first manhole 110 so that the pollutant isolation pipe 120 is inclined at a predetermined angle . It is generally known that when the storm flows in the direction of the first manhole 110 from the first manhole 110 to the second manhole 130, the direction of the second manhole 110 is horizontal, .

The pollutant separation pipe 120 is a means for transferring the primary filtration storm of the first manhole 110 to the inside of the second manhole 130 in the inside thereof, (124). The endless track device 124 may be operated by a sensing signal of the metering sensor 116. The caterpillar device 124 can be operated by a motor (not shown), and its speed can be determined according to preset conditions.

When the caterpillar 124 is moved slowly, the first bucket 122 of the plurality of buckets 122 pierces the primary filtration well of the first manhole 110 and moves upward And the second bucket 122, the third bucket, the fourth bucket, and the like, in the same manner as described above, sequentially insert the primary filtration water of the first manhole 110 into the interior thereof and gradually move upward. At this time, when the pollutants having a large specific gravity come down to the bottom portion and the return point of the infinite orbit is turned, the pollutants which have flowed into the bucket 122 may be polluted And then descends downward by the bucket 122 inverted in the opposite direction to finally return to the second storer reservoir 115 of the first manhole 110, I will come.

In this case, since the remaining rainwater in the bucket 122 comes down together, the inside of the pollutant separation pipe 120 is cleaned. Accordingly, as long as the caterpillar 124 is operated, it is not necessary to separately clean or wash the inside of the pollutant separation pipe 120.

Further, when the pollutant separation pipe 120 is passed through, the rainwater finally delivered to the second manhole 130 forms an excellent secondary filtration. As a result, it can be seen that the rainwater collected in the second manhole 130 is excellent in the secondary filtration in which heavy contaminants are removed from the primary filtration rainwater.

The present invention is characterized in that the second filtered well is stored in the second manhole 130 to suit the surrounding environment and used later, or the water is directly or indirectly supplied to the surrounding soil 240).

The utilization of the ambient condition of the storm (S 240) may be performed by using the second manhole (130) having a constant volume and capacity, targeting the secondarily filtered stormwater through the pollutant separation pipe (120) .

The second manhole 130 includes a body portion 132 buried in the ground and forming a volume of a predetermined volume, an inlet portion 134 connected to an upper end of the pollutant separation pipe 120, And an excellent storage tank 136 storing the secondary filtration storm that has been received through the inlet 134. The second manhole 130 may further include a permeate tank 138 that discharges slowly to surrounding subterranean soil when the stormwater stored in the storeroom reservoir 136 exceeds a predetermined storage capacity or reaches a preset storage capacity have.

The storm reservoir 136 may be constructed as a concrete facility or a storage facility made of stainless steel as an internal space for storing storm water secondaryly filtered therein. The storage capacity of the storm reservoir 136 may vary depending on the volume of the inner space, but may be interlocked with the permeation tank 138, depending on the use of the storage facility.

The interlocking relationship between the superior storage tank 136 and the permeation tank 138 can be performed by adjusting the height of the water level control unit 139. When the height of the water level adjusting part 139 is set to be low, when the storage amount of the secondary filtration storages stored in the excellent storage tank 136 is relatively small compared to the case where the height of the water level adjusting part 139 is set high, ).

The permeation tank 138 allows the secondary filtration water supplied from the second manhole 130 buried in the ground to infiltrate directly or indirectly to the surrounding ground. The permeation tank 138 may be embodied by conventional techniques. To this end, sand, gravel, and caustic sludge are filled into the permeate tank 138 or other attached devices connected thereto to gradually infiltrate the secondary filtration storm into the surrounding soil.

The second manhole 130 can be utilized in various forms in consideration of characteristics of an area in which the initial rainwater treatment system of the present invention is buried.

When the initial rainwater treatment system of the present invention has a relatively flat surface and is used in the school grounds or in the basement of an apartment complex using a large amount of water in the vicinity, the second manhole 130 is used as an excellent reservoir . School playgrounds can store large amounts of excellence and then be used in students' restrooms, used to cultivate flower beds in schools, or to grow trees. In this case, the size of the excellent storage tank 136 can be further increased.

On the other hand, in the case of urban suburbs, it is possible to use it after storing the stored storm, but it can be used as a source of the ground water which is being drained in the surrounding underground. Since the permeation tank 138 for this purpose has been described above, it will not be described repeatedly.

The operation of the initial rainwater treatment system using the excellent manhole of the present invention will be described below.

When rainfall occurs in an urban area, the rainwater on the ground slowly flows, and the nonpoint pollutants accumulated on the ground are rinsed and flowed into the surrounding manhole, and then the rainwater continues to flow.

The initial rainfall including the non-point pollutants flows into the inlet 112 of the first manhole 110, and gradually increases from the bottom to the top. The initial rainwater that has flowed into the inlet portion 112 is filtered by the redrawing mesh 114 installed inside the first manhole 110 to filter paper, vinyl pieces, branches, and the like mixed in the initial rainfall.

The initial rainfall including the non-point pollutants is separated into two regions inside the first manhole 110 by the pulling wire 114. [ The first storer 113 may still contain paper, vinyl pieces, twigs, etc. mixed with the initial storages, while the second storeroom 115 may contain primary, It contains filtration excellence.

When the rainwater is continuously supplied to the first manhole 110, the rainfall measuring sensor 116 senses the rainwater. In accordance with the sensed signal, the control unit (not shown) The caterpillar device 124 existing in the vehicle is operated.

When the caterpillar 124 starts to move slowly, the plurality of buckets 122 accumulate inside the first manhole 110 and gradually move along the sloped surface. The primary filtration water of the inside of the bucket 122 descends to the vicinity of the bottom of the bucket 122 while the remaining primary filtration water is separated upward.

When the caterpillar 124 is slowly moved to the vicinity of the second manhole 130, the bucket 122 rotates while the secondary filtration surplus remaining in the second manhole 130 And the heavy pollutants in the vicinity of the bottom return to the first manhole 110 from the inside of the pollutant separation pipe 120 again.

Secondary filtration stormwater poured into the second manhole 130 is stored in the stor- age storage tank 136 and can be usefully used for domestic water. If necessary, it is sent to the permeation tank 138, It will supply moisture.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, The range is determined and limited.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the present invention.
