Description

High efficiency non-point pollution abatement device

The present invention relates to a high-efficiency non-point pollution reduction device, and more particularly, rainwater flowing into a sedimentation tank is purified through a fiber filter and discharged, and a fiber filter that purifies the rainwater is automatically washed through a washing means. It is washed with a vacuum cleaner and used semi-permanently, thereby minimizing the cost, time, and manpower required for filter replacement compared to the conventional non-point pollution reduction device, thereby preventing inconvenience and uneconomical operation of the device, making the device convenient and convenient. It relates to a high-efficiency non-point pollution reduction device that can be operated economically.

Pollution sources generated in urban areas are largely divided into point pollution sources and nonpoint pollution sources. A point source is a source of pollution that has a specific discharge path that can be expressed as a single point, such as household sewage and factory wastewater, and is relatively easy to treat because the movement route is clear. It refers to an emission source that discharges water pollutants in an unspecified place, such as in an unspecified place (refer to the Water Quality and Aquatic Ecosystem Conservation Act).

Unlike point sources that are continuously generated at specific points, such as domestic sewage or factory wastewater, these non-point sources are scattered sources, and it is difficult to determine the exact outflow path and the inflow is non-continuous. In particular, it is difficult to collect pollutants because the outflow and discharge routes are not clearly distinguished, and the amount of pollutants generated and discharged depends greatly on weather conditions such as precipitation. In addition, types of nonpoint pollutants include soil, harmful bacteria, heavy metals, pesticides, and contaminants.

In addition, the importance of nonpoint pollution sources as a pollution source was not recognized because the outflow of nonpoint pollution sources is concentrated only during rainfall and the pollution sources are dispersed over a wide area. However, in the case of first-flush, where nonpoint pollutants from the surface of the earth are discharged in the early stages of rainfall, the runoff concentration of nonpoint pollutants is high, and especially in urban areas, there is a high possibility of containing toxic substances such as heavy metals, so appropriate control measures are required. have. In other words, the occurrence of nonpoint source discharge due to rainfall is very irregular, contains many kinds of non-decomposable nonpoint source pollution, and the amount of generated overload is large, that is, the flow rate fluctuation with time is large, and the concentration of nonpoint source pollution at the beginning of rainfall is large. has the characteristic of rapidly increasing.

Therefore, it is difficult to collect and treat pollutants such as soil, nutrients, and high-concentration heavy metals flowing out from non-point pollution sources along with rainfall. The habitat is destroyed and the aquatic ecosystem is disturbed.

In order to solve the above problems, the non-point pollution reduction device for purifying rainwater containing non-point pollution sources is to collect and purify foreign substances remaining in rainwater through a filter. The operation of the device is difficult and inconvenient because replacement cost, replacement time, and manpower are required, and there is a problem in that it is difficult to smoothly operate the device because it takes too much cost to operate and manage the device.

The present invention has been proposed to solve the various problems as described above, and its purpose is that the rainwater flowing into the settling tank is purified through a fiber filter and discharged, and the fiber filter that purifies the rainwater is automatically washed through a washing means. By making it semi-permanent, it minimizes the cost, time, and manpower required for filter replacement compared to the conventional non-point pollution reduction device, thereby preventing inconvenience and uneconomical operation of the device, making the device convenient and economical. It is to provide a high-efficiency non-point pollution reduction device that can be operated.

In addition, the fiber filter formed in the settling tank can very effectively collect and purify the foreign substances of rainwater through the dust collection induction means. to provide the device.

As shown in the figure, the high-efficiency non-point pollution reduction device 100 according to the embodiment of the present invention includes a settling tank 10 , a fiber filter 20 , and a dust collection guide means 30 .

1, the sedimentation tank 10 has a space in which rainwater is accommodated, an inlet 11 through which rainwater is introduced is formed at the lower portion, and an outlet through which purified rainwater is discharged at the upper portion. (12) is formed.

Here, the settling tank 10 is a structure through which the rainwater that needs to be purified is introduced, and it goes without saying that a device such as a pump may be installed at the inlet 11 for easy inflow of rainwater.

1 and 2, the fiber filter 20 is formed at the center of the settling tank 10 to divide the settling tank 10 into a lower space and an upper space, and the inlet 11 Collect foreign substances remaining in the rainwater flowing into the furnace.

Here, the fiber filter 20 is formed by stacking a plurality of skeins in a zigzag manner, and as shown in FIG. 3A , when the central portion is lifted upward by the dust collection guide means 30 to be installed later, the plurality of skeins are formed. As the voids of the fiber filter 20 are densely overlapped, the foreign substances remaining in the rainwater through the fiber filter 20 are effectively collected.

At this time, both ends of the fiber filter 20 are bound to the settling tank 10 and, of course, when the central portion of the fiber filter 20 is lifted, it is bent and deformed into a hat shape.

As shown in FIGS. 1 and 2 , the dust collection guide means 30 lifts the central portion of the fiber filter 20 fixed at both ends when rainwater flows into the inlet 11 of the settling tank 10 . By densely forming the pores of the fiber filter 20 to induce the foreign matter remaining in the rainwater to be effectively collected through the fiber filter 20,

One end is connected to the inlet 11 of the settling tank 10 , and the other end is positioned to face upward from the center of the settling tank 10 , and the rainwater flowing into the inlet 11 is directed above the center of the settling tank 10 . When rainwater is discharged through the elevating pipe 31 and the elevating pipe 31 and discharged through the elevating pipe 31, A lifting panel 32 formed in the shape of a hat so that it can be easily lifted by the elevating panel 32, and connected to the upper portion of the lifting panel 32 to support the lower center of the fiber filter 20, the lifting panel 32 and A long bar-shaped pressing rod 33 that elevates and descends together and is coupled and fixed to the settling tank 10 to support and fix the elevating panel 32 , while guiding the vertical elevating and lowering of the elevating panel 32 . It is configured to include a guide guide (34).

That is, when rainwater introduced into the inlet 11 of the settling tank 10 is discharged upward through the elevating pipe 31 of the dust collection guide means 30 as shown in FIG. 3A , the water pressure of the discharged rainwater As the compression rod 33 rises upward together with the lifting panel 32 by pressing and pressing the fiber filter 20, the pores of the fiber filter 20 are densely formed.

Therefore, since foreign substances remaining in the rainwater flowing into the inlet 11 of the settling tank 10 and passing through the fiber filter 20 are very effectively collected in the fiber filter 20, excellent purification of rainwater is performed.

Then, as shown in FIG. 3B , when the inflow of rainwater into the inlet 11 is stopped, the water pressure pushing up the lifting panel 32 is released, so that the lifting panel 32 naturally descends and returns to the pressing rod. The compression of the fiber filter 20 through (33) is released.

Here, the elevating panel 32 receives the guidance of the guide guide 34 to stably elevate and descend vertically.

In addition, as shown in FIGS. 1 and 2 , a plurality of branch holes 40 formed through the lifting panel 32 are further included.

That is, as shown in FIG. 3A , a portion of rainwater discharged to the lifting panel 32 is directly supplied to the fiber filter 20 through the branch hole 40 formed on the lifting panel 32 , so that the By guiding the rainwater flowing into the inlet 11 of the settling tank 10 to be evenly supplied and passed through the entire fiber filter 20, the efficiency of use of the fiber filter 20 can be maximized, thereby inducing effective purification of rainwater.

On the other hand, as shown in FIGS. 1 and 2, a washing means 50 for inducing semi-permanent use of the fiber filter 20 by removing foreign substances collected in the fiber filter 20; ,

The washing means 50 is located on the upper part of the fiber filter 20, and at the lower part of which a plurality of spray nozzles 51a for supplying air to the fiber filter 20 are formed, one or more cleaning pipes 51 and , a supply pipe 52 for guiding and supplying air supplied through the blower 53 to the cleaning pipe 51 , a blower 53 for sucking and supplying air to the supply pipe 52 , and the settling tank 10 . ) formed at the bottom of the cleaning pipe 51 and discharged to the fiber filter 20 through the air outlet 54 for discharging rainwater to the outside together with foreign substances falling off and falling from the fiber filter 20 is comprised of

That is, as shown in FIG. 3C , when a large amount of foreign matter is collected in the fiber filter 20 due to long-term use of the fiber filter 20 and cleaning of the fiber filter 20 is required, the washing means ( 50) by supplying air to the supply pipe 52 through the blower 53 to the fiber filter 20 through the spray nozzle 51a of the cleaning pipe 51 communicating with the supply pipe 52. It causes strong wind (air) to be expelled.

Then, due to the nature of the fiber filter 20 being formed of a plurality of skeins 21, the skeins 21 of the fiber filter 20 are strongly blown away by the wind force, and the foreign substances collected in the fiber filter 20 are separated. It descends, and the separated and descended foreign substances are discharged through the outlet 54 together with the rainwater contained in the lower part of the settling tank 10 so that the fiber filter 20 is easily washed.

Here, during the operation of the washing means 50 , the inflow of rainwater is blocked through the inlet 11 of the settling tank 10 , and the inflow of rainwater is blocked through the inlet 11 . Since the fiber filter 20 is prevented from being lifted by the dust collection inducing means 30 , the pores of the fiber filter 20 are maintained rather large, so that the cleaning means 50 is very effectively cleaned by the wind power.

On the other hand, it goes without saying that a pump capable of forcibly sucking and discharging rainwater together with foreign substances may be installed in the outlet 54 .

In the high-efficiency non-point pollution reduction device 100 of the present invention comprising the above components, the rainwater flowing into the settling tank 10 is purified through the fiber filter 20 and discharged, and the fiber filter for purifying the rainwater ( 20) is automatically washed through the washing means 50 so that it is used semi-permanently, thereby minimizing the cost, time, and manpower required for filter replacement compared to the conventional non-point pollution reduction device There is an effect that the device can be operated conveniently and economically by preventing damage and uneconomical operation.

In addition, the fiber filter 20 formed in the settling tank 10 can very effectively collect and purify rainwater foreign substances through the dust collection induction means 30, so that it can be reused by expanding the rainwater to various fields. It has the effect of overcoming the reuse limit of
