Description

TECHNICAL FIELD [0001] The present invention relates to a multi-stage non-point pollutant abatement apparatus for a bridge capable of collecting oil components,

The present invention relates to a device for preventing contaminants accumulated on a surface of a bridge from flowing into a river, and more particularly, to a device for preventing contaminants, particularly oil contaminants And to prevent the environmental pollution of water resources by preventing the water from flowing into the river.

Until now, it has been the policy direction of the main water quality management to prevent contamination of water quality through disposal of point pollutant sources such as sewage, wastewater and livestock manure which are easy to generate and track pollution sources.

However, as urbanization progresses, land use becomes more diverse and advanced, and nonpoint source pollution increases. Therefore, water quality management centering on the above point pollution source has a limitation in preventing pollution of water resources.

Non-point pollution source refers to a pollutant source that flows into public waters such as rivers due to effluent flowing out during rainfall through various land use forms. It is not easy to manage and dispose of, and pollutants generated from such non- It is known that the water quality of the water source is very influential.

Especially, pollutants accumulated on the pavement of roads and bridges contain a large amount of various heavy metals such as zinc and lead, which are generated by vehicles, and measures against such pollutants are very urgent.

Various methods and apparatuses have been developed to prevent non-point pollutants from flowing into rivers and the like. One example of such an apparatus is disclosed in Korean Patent Registration No. 10-1339617, entitled " have.

As shown in FIG. 1, the non-point pollution remediation apparatus includes an initial storm collector pipe 20 and a subsequent storm drain pipe 22 branched from and connected to the lower portion of the catch 12 of the bridge slab 10; A non-point polluted water purification tank (230) (26) capable of collecting an initial storm discharged through the initial storm collector pipe (20) to a predetermined height; A non-point pollution filter device (30) installed inside the non-point polluted water purification tank (230) (26) to filter foreign matter contained in the initial rainwater and discharge the foreign matter to the bridge water pipe (14); An excellent directional valve (52) for determining the discharge flow path of the rainfall introduced from the catching hole (12) to selectively flow either the initial storm collector pipe (20) or the subsequent rainfall drain pipe (22); A water level sensing means (40) for sensing a level of an initial storm that has flowed into the non-point polluted septic tank (230) (26); And a valve motor 50 for operating the superior directional valve 52 according to an electrical signal of the water level sensing means 40 to determine the discharge passage for the initial storm and the subsequent rainfall.

In the above-mentioned prior art non-point pollution purification apparatus, when there is no rainfall, the motor control device rotates the valve motor 50 to rotate the forward directional valve 52 to the forward position, and the subsequent rainfall- (22) is closed with the upper direction inlet valve (52) and the early stage collector pipe (20) is connected to the catching port (12). When the rainfall occurs in this state, the initial rainwater passes through only the early stormwater collector pipe 20, flows into the non-point polluted water purification tank 230 (26), purified through the non-point pollution filter device 30 and then sent to the bridge water pipe 14 The detection switch 42 is turned on in accordance with the rising of the level of the water level detecting means 40. When the temperature of the non-point polluted tank 230 is lower than the predetermined level, And the subsequent rainfall water pipe 22 is connected in a straight line direction with the catching port 12 so that the subsequent rainfall is transmitted to the non-point polluted water purification tank (not shown) 230) 26 directly to the bridge drain pipe 14 through the subsequent rainfall drain pipe 22. [ At this time, the operating state of the outward direction valve 52 is continuously maintained for a set time in anticipation of the time period during which the rain is continuously lowered, so that the outflow directional valve 52 opens the subsequent rainfall drain pipe 22 for a predetermined time.

This prior art non-point pollution cleaner is positive in that it can efficiently remove pollutants by purifying only the initial pollutants having a relatively high pollutant concentration during rainy days. However, the initial pollutant discharge pipe 20 and the subsequent rainwater discharge pipe 22 are made by the superior directional valve 52 which moves back and forth by the operation of the valve motor 50 so that the malfunction of the valve motor 50 or the directional valve 52 causes malfunction This malfunction can not exclude that the initial storm having a high concentration of pollutants can be sent to the subsequent rainfall drain pipe 22 rather than the early water collecting drain pipe 20 and the initial rainwater drain pipe 20 and the non- It is not easy to collect pollutants such as refuse settled on the bottom of the tank (230) 26 and to clean the non-point pollution filter device (30) The use of electrical energy for the operation of 50 is increasing the problem to break down maintenance costs and durability.

Furthermore, the prior art non-point pollution cleaner can only remove particulate pollutants, and can not remove pollutants such as oil components such as oil leaked from the vehicle, thereby limiting environmental pollution.

The non-point pollutant abatement apparatus of the present invention is connected to a water discharge pipe (P1) provided in a drain port of a bridge, and includes a separation pipe (100) And a purifier 200 for discharging the purified water to the drain pipe P2.

The non-point pollutant abatement apparatus of the present invention is capable of efficiently purifying pollutants of various shapes in a multi-stage system. The separation pipe 100 is a part having a purification function in one step, And the like, from the storm.

5 is a cross-sectional view for explaining the structure of the separation pipe 100 and a partial perspective view thereof.

The separation pipe 100 is composed of a vertical linear pipe 110 and a slant pipe 120 branched downward from the linear pipe 110 as shown in FIG.

That is, in the separation pipe 100, the large volume contaminants are introduced into the collection vessel 210 of the purification apparatus 200, which will be described later, through the slant pipe 120, To another portion of the purifier 200 through the purifier 110.

To this end, the separation tube 100 is provided with a screen filter 131 for preventing such large volume contaminants from passing therethrough. 5 (a), the screen filter 131 is installed on the linear straight pipe 110 having a lattice-like net structure, and most preferably, l) to traverse the straight pipe 110.

Therefore, when large volume contaminants such as vinyl are introduced into the separation pipe 100 together with the rainwater, the rainwater passes through the screen filter 131 and falls into the straight pipe 110 in the downward direction. However, 131), and then slid down to the slanting pipe (120).

At this time, anti-sticking vanes 132 having a wedge sectional shape inclined downward can be further provided on the upper surface of the clean filter at regular intervals.

The anti-adhesion vane 132 prevents the contaminants from adhering to the screen filter 131 due to the sliding action against the filtered contaminants, thereby inducing smooth movement of the anti-adhesion vane 132 to the inclined pipe 120 without interfering with the flow of the excellent flow.

The high and high volume contaminants that have passed through the straight pipe 110 and the slant pipe 120 of the separation pipe 100 are moved to respective portions of the purification device 200, A collection tank 210 for collecting large volume contaminants introduced through the vertical pipe 120, a water storage tank 220 for removing oil components from the stormwater introduced through the linear pipe 110, A purifier 230 and a housing 240 for housing the collection tank 210, the water storage tank 220 and the purification tank 230 and discharging the discharged stormwater to the drain pipe P2.

The collection vessel 210 is a part that collects large volume contaminants by the screen filter 131 installed in the separation tube 100 and allows the contaminants to be taken out to the outside. And one side of the side surface is exposed to the outside air as shown in FIG. 3, and the open / close door 211 is installed on the exposed side so that the collected contaminants can be easily taken out to the outside.

The inner space of the collection tank 210 may be used as a pollutant collection space. Preferably, however, the inner space of the collection tank 210 may include a retrievable dust bag 213, It is preferable that contaminants can be contained in the contaminant collecting bag. To this end, a ring (not shown) may be further provided on the inner wall of the collecting container 210 so as to hang the contaminant collecting bag.

On the other hand, as the large volume contaminants filtered by the screen filter 131 move to the slanting pipe 120, some rainwater flows into the slanting pipe 120 together with the contaminants. As a result, It is preferable that the filter is made of a material and a structure that can be dewatered by filtering the contained particulate pollutants.

In addition, the lower end of the sidewall of the collection tank 210 or the bottom plate may further include an excellent discharge port 212 for discharging the rainwater introduced together with the large volume of contaminants. The discharge port 212 may be provided with a filter, It is also possible to form fine discharge ports 212 by piercing them with fine holes. The storm that has passed through the storm drain 212 flows to the drain pipe P2 through the discharge pipe 241 provided at the lower part of the housing 240. [

As the heavy volatile contaminants are removed, the stormwater flowing through the straight pipe 110 is temporarily stored in the low-temperature and high-temperature water tank 220, and is subjected to a two-stage purification operation in which contaminants of oil components and large particle contaminants are removed.

As shown in FIG. 4 (a), the bottom of the storage tank 220 is divided into a first settling portion 221 for collecting large particle contaminants so as to be collected, And an oil pocket portion 223 for collecting contaminants of the oil component in the upper portion.

In other words, large particle contaminants that have a specific gravity larger than that of water are deposited on the first settling portion 221 located at the bottom, while contaminants of an oil component having a specific gravity smaller than that of water float on the surface of the superior, 223).

The separation action of these contaminants becomes more effective when a vortex is formed in the stormwater in the storage tank 220. To this end, the purifier 200 may further include a non-powered vortex generator.

A screw pipe 140 having a screw 141 for generating a vortex is extended and a lower end of the screw pipe 140 is passed through a side wall of the water storage tank 220 The water flowed into the softened straight pipe 110 is allowed to flow into the water storage water flow tank 220 while rotating on the screw 141 to prevent the water stored in the water storage tank 220 from flowing into the water storage tank 220 ) To generate a vortex.

The vortex generated in this way facilitates the separation of liquids having different specific gravity so that light oil component contaminants can be efficiently collected in the upper oil pocket portion 223.

The oil pocket portion 223 located at the upper portion of the water retention tank 220 has a ceiling formed in a stepped shape with two steps and is divided into a first pocket portion 223a having a large height and a second pocket portion 223b having a small height . An overflow hole 224 is formed in the second pocket portion 223b.

The initial storm having a high concentration of pollutants flows through the low-temperature and high-pressure circulation tank 220 to a purification tank 230, which will be described later, and is subjected to a purification process by adsorption and filtration at the next stage.

However, when the amount of stormwater flowing into the water storage tank 220 becomes greater than the amount of water flowing into the septic tank 230, it can be said that the state of the initial storm is almost complete, .

The overflow hole 224 formed in the second pocket portion 223b is formed in such a manner that the latter is discharged from the housing 240 immediately after passing through the septum 230 without passing through the septic tank 230. [ And flows to the drain pipe (P2) through the pipe (241).

In this case, a ring-shaped downward protruding protrusion 224a may be further provided on the outer circumference of the overflow hole 224 so that contaminants of the oil component collected in the second pocket portion 223b are not discharged together. In order to improve the collection ability, the first and second pocket portions may further include an adsorbent 224b.

Large particle contaminants with large and heavy specific gravity are precipitated downward and deposited on the first settling portion 221 located at the bottom in spite of the occurrence of the vortex. The first settling portion 221 efficiently accumulates the contaminants, It is preferable that the structure is made of the same material.

For example, the first settling portion 221 is formed in a funnel shape by inclining the bottom plate of the water storage and flow tank 220 downward, and a first contaminant carry-out pipe 222 is provided at a lower portion thereof. In addition, the first pollutant takeoff pipe 222 is provided with an on-off valve 222a.

Therefore, the pollutants collected in the funnel-shaped first settling portion 221 are opened by opening the on-off valve 222a, and when the water contained therein is poured to the outside through the first pollutant take-out pipe 222, So that the removal and cleaning of contaminants in the water storage tank 220 becomes very easy.

At this time, a stopper (not shown) is formed on the outer surface of the first pollutant take-out pipe 222, and the pollutant discharged from the first pollutant take-off pipe 222 can be more easily treated have.

The initial rainwater flowing into the water storage trough 220 flows into the water purification tank 230 after heavy sedimented particles and light oil components are filtered. In the water purification tank 230, Particulate contaminants, such as suspended particles, are filtered together with particle contaminants.

A first induction pipe 225 is installed in the upper part of the water storage tank 220 and a second induction pipe 231 and purified purified water discharge pipe 241 are connected to the purification tank 230 And the first induction pipe 225 and the second induction pipe 231 are communicated with each other through the communicating pipe 226. The discharge pipe 232 is connected to the first induction pipe 225 and the second induction pipe 231,

Therefore, the small particle contaminants floating due to the formation of the vortex move to the septic tank 230 via the first induction pipe 225, the communication pipe 226 and the second induction pipe 231 together with the storm.

The lower end of the second induction pipe 231 is located up to the lower portion of the bottom of the purifier 230 and the outlet pipe 232 is connected to the outlet pipe 241, As shown in Fig.

Accordingly, the rainwater discharged from the second induction pipe 231 is upwardly moved in the interior of the purification tank 230 and is drawn into the discharge pipe 232. In the present invention, the rainwater passes through the purification unit 233 Whereby the three-stage purifying action by adsorption and squeezing can be performed.

The purification unit 233 includes a biochip charging unit 233a and an upper filter unit 233c as shown in FIG. 4 (b). Therefore, the rainwater discharged from the lower end of the second induction pipe 231 passes through the biochip-filled part 233a to primarily allow the suspended matter to be adsorbed by the biochip, and then is struck by the three-dimensional filter of the filter part 233c After removing the small particle contaminants, it is transferred to the discharge pipe 241 through the discharge pipe 232.

The discharge pipe 232 may have a plurality of inlet holes formed therein and then be embedded in the filter. In this case, however, the outlet pipe 232 passes only in the horizontal direction of the filter, There is a problem.

Therefore, the lower end of the filter portion 233c is connected to the upper end of the discharge pipe 232, so that the water can pass through the filter portion 233c by a sufficient depth to maximize the effect of purifying by the filter desirable.

At the upper and lower portions of the biochip filler 233a, a separation prevention network 233b is provided. The detachment prevention network 233b prevents the biochip from being displaced and lost during the cleaning process of the excellent or during the internal cleaning process for maintenance.

Most of the heavy particles having a larger specific gravity than the water introduced along with the storm are settled in the first settling portion 221 of the water storage tank 220 as described above, 225, and 231 to the purified water tank 230.

The remaining heavy particles that have not been precipitated in the first settling portion 221 and thus flowed into the purified water tank 230 are settled in the purified water tank 230. In the lower portion of the purified water tank 230, ), As well as a structure for allowing the precipitated particle contaminants to be easily taken out to the outside can be provided.

A second settling portion 234 having a downwardly inclined shape is formed on the bottom plate 234 and a second settling pipe 235 is provided below the second settling portion 234, Off valve 235a is installed in the take-out pipe 235, the lower part of the purifying tank 230 can be constituted.

Of course, it is possible to simplify the treatment of the contaminants discharged from the second pollutant take-out pipe 235 by forming a catch on the outer surface of the second pollutant take-out pipe 235 and hanging the pollutant collecting bag thereon.

FIG. 6 is a general view of the process of removing the non-spot pollutants contained in the initial rainwater through the water storage tank 220 and the purified water tank 230 as described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious that it will be possible to carry out various modifications thereof. It is therefore intended that such modifications are within the scope of the invention as set forth in the claims.
