Description

Non-point source a contaminant purification system of first rain}

The present invention relates to an initial excellent non-point pollution treatment system for separating and purifying initial rainwater containing a large amount of non-point pollutants during rainfall, and preventing excessive rain from flowing into the river.

Water sources are largely divided into point sources and nonpoint sources. Point sources are mainly traceable to the origin and volume of livestock sewage from households or business areas, industrial wastewater from factories, and livestock wastewater from large livestock facilities. These relatively easy ones are the main targets for sewage treatment.

On the other hand, nonpoint source refers to drainage from agricultural drainage, mine wastewater, livestock wastewater of small livestock facilities, and rural sewage or forestry in rural areas without sewerage. These pollutants are less contributing to pollution and rely on natural treatment.

To emphasize, nonpoint sources are also referred to as non-specific sources, cotton sources, mobile sources, or other water sources. Unlike point sources that have specific discharge pathways, nonpoint sources are unspecified, such as urban road drainage or agricultural drainage. Point to a location or area that generates a nonpoint pollutant through an emission pathway.

Aquaculture aquaculture facilities, golf course facilities, transportation equipment, maintenance or junkyard facilities, concentrated aquatic products simple processing facilities, photograph processing facilities, etc., which have been renamed from `` specific facilities '' to `` other water pollution sources '' under the Water Quality Preservation Act; This includes other facilities such as product yards, product yards, and land quality change areas.

Nonpoint pollutants are mainly pollutants that are discharged along with surface runoff when it rains. Fertilizers, pesticides, soil erosions, barn spills, traffic pollutants, urban dust and garbage, residues of natural animals and plants It refers to water and air pollutants that fall on the ground.

Therefore, the rainwater discharged, including all pollutants, is in fact the main nonpoint source. Non-point pollutants are usually discharged only when there is a lot of rain, so they have a large difference in daily and seasonal emissions, difficult to predict and quantify, and are affected by weather conditions, geology, and terrain, which are difficult to control artificially. Therefore, emission standards are not systematically set.

As a result of the 'Non-point Pollution Research Service' (June 2000) on the upstream area of Paldang Dam, the main source of water for residents of the Seoul metropolitan area, as of the end of 1999, Pollutant loads generated from point sources such as industrial wastes and livestock wastes were 13,6509 tons per year, which is 80.4%, and 331 393t / year, which was 19.6%.

In addition, the total discharge load (BOD basis) is estimated to be 44.5% of nonpoint source, which indicates that the nonpoint source has a significant effect on water pollution. The similarities are found in the Geum, Nakdong, and Youngsan rivers. It is estimated to show. Therefore, as the regulations on point sources with regulatory standards have been strengthened and environmental foundations are expanded, the influence of nonpoint sources on water quality will gradually increase.

On the other hand, in such a problem, conventionally, as a measure to reduce pollution, road drainage in urban areas is to install a storage tank to settle and discharge pollutants caused by the initial rain, and discharged from farmland. • Agricultural drainage containing a large amount of pesticides has been installed with reservoirs, wetland purification facilities, and water plants to prevent direct entry into rivers.

However, this countermeasure reduces the efficiency of the non-point pollution treatment facility by continuously purifying the rainwater after a certain period of time when the concentration of pollutants is reduced. There was a problem that the maintenance cost was increased, and there was no function to cope with the flood because it could not control the amount of rainwater flowing into the river rapidly during heavy rains.

The present invention has been made to solve the above problems, the object of the present invention is to focus on the fact that the non-point pollutants included in the rainwater is reduced in the initial excellent, most non-point pollutants, It is to reduce the water pollution by providing an initial excellent non-point pollution treatment system according to the present invention for separating and purifying the initial excellent water.

In addition, another object of the present invention is to mitigate or prevent flooding through the rain tank and the drain pipe according to the present invention.

An object of the present invention as described above is the initial excellent separation unit provided on the inner surface of the rainwater receiver corresponding to the direction in which rainwater is introduced, the first screen provided on the initial excellent separation unit and separating the foreign matter, and the initial The non-point pollutant purification unit having a filter for filtering nonpoint contaminants contained in the rainwater by receiving the rainwater separated from the first screen of the rainwater separator and the rainwater flowing in from the rainwater discharged by the nonpoint pollution purification unit. In the case of exceeding the treatment capacity of the non-point pollution purification unit, the initial excellent catchment expansion unit which induces the rainwater that is continuously introduced and temporarily stores it and supplies the stored rainwater to the non-point pollution purification unit according to the rainwater discharge amount of the non-point pollution purification unit, and the initial Blocking unit to block rainwater supply from the initial rainwater separator when the stormwater storage capacity exceeds the stormwater storage expansion The initial boiling point and excellent contamination processing device comprising; A plurality of through holes are formed in an upper portion to form an overflow section, and one side of the drain pipe is connected to one side of the initial excellent non-point pollution treatment apparatus; It is achieved by the initial excellent non-point pollution treatment system comprising a; rain tank to accommodate the overflow section of the drain pipe, the interior is empty space and the lower part is opened to discharge the rainwater.

According to the initial excellent non-point pollution treatment system according to the present invention, since only the initial rainwater is separated / purified from each rainwater receiver, it is possible to reduce or eliminate the size of the final purification facility provided before sending rainwater to rivers, seas, and the like.

In addition, since the initial excellent non-point pollution treatment apparatus according to the present invention separates and purifies only the initial excellent and other rains are sent to the excellent receiver as it is, unnecessary purification treatment is not performed, thereby increasing the replacement cycle of various consumables required for purification. This improves the initial good purification efficiency and reduces the maintenance costs.

In addition, due to the configuration of the drain pipe and the rain tank according to the present invention during heavy rains can be discharged to some underground to reduce the amount of rainwater flowing into the river, etc., there is an effect that can be reduced or prevented floods.

Hereinafter, with reference to the accompanying drawings showing a preferred embodiment of the present invention will be described in detail.

More rainwater is introduced than rainwater discharged by the non-point pollution purification unit 20, and when the excess capacity of the non-point pollution purification unit 20 is exceeded, the rainwater is continuously stored and induces rainwater that is continuously introduced. An initial excellent catchment expansion unit 30 for supplying the stored rainwater to the non-point pollution purification unit 20 according to the rainwater discharge amount of 20;

An initial excellent non-point pollution treatment apparatus including a blocking unit to block supply of rainwater from the initial rainwater separating unit 10 when the rainwater storage capacity of the initial rainwater collecting unit 30 is exceeded;

A plurality of through grooves 71a are formed in an upper portion to form an overflow section L, and one side of the drain pipe 71 is connected to one side of the initial excellent non-point pollution treatment apparatus;

It includes; a rain tank (72) for receiving the overflow section (L) of the drain pipe (71), the interior is an empty space and the lower part is open to discharge rainwater.

Here, the overflow section (L) of the drain pipe (71) is shown in detail in Figure 3, the through groove (71a) is formed in the upper as shown in Figure 2 rainwater flowing from the initial excellent non-point pollution treatment device Excessive amount of is a role to discharge it, rainwater discharged through the through groove (71a) is moved to the lower side of the rain tank 72 is absorbed underground through the gravel layer (74).

In addition, the rain tank 72 has a closed cover on all surfaces except the lower surface of the rain tank 72 so that rainwater discharged through the through groove 71a of the drain pipe 71 is discharged only in the downward direction of the rain tank 72. It is preferable to include 82 (e.g., vinyl) and a nonwoven fabric 82, and to adjust the pressure in the rain tank 72 to improve the underground absorption rate of rainwater to improve the inside of the rain tank 72 It is preferable to have a pressure control tube 73 as shown in Figure 2 so that the air flows. At this time, the nonwoven fabric 82 is configured to prevent breakage of the airtight cover 82, and if there is another configuration to replace it, it is possible to replace it as well.

Meanwhile, the non-point pollution purification unit 20 separates the second screen 21 which separates the foreign matter contained in the rainwater again before the rainwater 300 introduced from the initial excellent separation unit 10 is supplied to the filter agent 22. It is preferable to have more,

The blocking unit is hinged to one end of the inlet pipe 41 which is a flow path of the rainwater 300 flowing from the initial excellent separation unit 10 to block or open the inlet pipe 41, and the It is preferable to comprise a floating port 52 attached to one side of the blocking plate 51, the upper portion of the initial excellent water collecting expansion portion 30 and the non-point pollution purification unit 20 is removable and can be opened and closed. The cover 90 may be provided, and the inner bottom of the initial excellent water collecting extension 30 may further include sediment receivers 63 and 64.

When explaining the configuration in more detail and the operation relationship at the same time,

As rainwater flows from the left side of the road 400 as shown in FIG. 6, the initial excellent separation unit 10 is mounted on the upper side of the inner side of the rainwater receiver 100 corresponding thereto. Then, unless it is a heavy rain, the initial rainwater is continuously introduced into the initial rainwater separating part 10, and the rainwater flowing through the inlet pipe 41 connecting the initial rainwater separating part 10 and the initial rainwater separating part 60. It flows into the initial excellent isolation unit (60).

At this time, the first screen surrounding one side of the inlet pipe 41 connected to the inner side of the initial excellent separation unit 10 in order to prevent the inflow pipe 41 from clogging due to the introduction of a relatively large amount of foreign matter into the inlet pipe 41. 11) Install.

On the other hand, the initial excellent isolation unit 60 is composed of a non-point pollution purification unit 20 and the initial excellent catchment expansion unit 30 to distinguish this from the inner wall of the initial excellent isolation unit 60 extending from the lower side to the upper portion Form 61.

Therefore, the initial rainwater introduced through the inlet pipe 41 is primarily introduced into the non-point pollution purification unit 20, and the rainwater exceeds the partition wall 61 when the capacity of the non-point pollution purification unit 20 is exceeded. The initial excellent catchment expansion unit 30 is moved.

Rainwater introduced into the non-point pollution purification unit 20 is purified while passing through the filter agent 22 provided at the bottom and discharged through the discharge pipe 42. In this case, the rainwater flowing into the non-point pollution purification unit 20 may include relatively small foreign matters even though the first screen 11 separates foreign matters, and thus, the foreign matters may accumulate on the filter 22. Then, the efficiency of the filter agent 22 is reduced, so that the rainwater is provided with the second screen 21 as shown in FIGS.

And the filter agent 22 of the non-point pollution purification unit 20 is configured to purify the non-point pollutants contained in the rainwater, such a configuration is less than the rainwater discharged into the rainwater is introduced into the control of the permeability coefficient after a certain time, It is saturated. Then the rainwater is moved to the initial excellent catchment expansion unit 30, as shown in Figure 6, the rainwater temporarily stored in the initial excellent catchment expansion unit 30 through the communication pipe 62 formed in the lower portion of the partition wall 61 Rainwater is introduced into the non-point pollution purification unit 20 because the initial excellent catchment expansion unit 30 and the non-point pollution purification unit 20 communicate with each other.

On the other hand, if it exceeds the excellent storage capacity to pass through the saturation state of the non-point pollution purification unit 20 to the initial excellent catchment expansion unit 30, as shown in Figure 6 by the blocking portion provided on the other side of the inlet pipe 41 Block rainwater inflow. The blocking part is composed of a blocking plate 51 mounted with a buoyancy float 52 on one side. The blocking plate 51 is hinged with the inlet pipe 41, but normally opens the inlet pipe 41. It is desirable to hinge to act.

Then, the blocking portion normally opens the inlet pipe 41, and if the buoyancy of the floating port 52 is greater than the action force to open the inlet pipe 41 (excellent storage capacity to the initial excellent catchment expansion portion 30 is exceeded) Case) the inlet pipe 41 is blocked.

The rainwater that has passed through the filter medium 22 in this way, or the rainwater that is overflowed from the initial rainwater separating part 10 and moved to the inside of the rain receiver 100 is moved to the drain pipe 71. And some of the movement of rainwater is moved into the rain tank 72 through the through groove (71a) formed in the overflow section (L) of the drain pipe 71 and some rainwater is outside (manhole, etc.) through the other side of the drain pipe (71) Is discharged to. On the other hand, since the rain tank 72 is only the bottom surface is open state rainwater moved into the rain tank 72 slowly penetrates to the basement through the gravel layer 74 is formed in the lower portion of the rain tank (72). The gravel layer 74 serves to prevent the partial settlement of the rain tank 72, and the rain tank 72 serves to fill the rainwater underground and at the same time fill some rainwater underground, thereby controlling the flood. Do it.

And when the rainwater that is moved into the rain tank 72 is more than the rainwater that penetrates underground, most rainwater is discharged to the outside through the other side of the drain pipe 71 as described above when the space of the rain tank 72 exceeds Therefore, when filling a larger amount underground, as shown in Figure 4 can be configured by stacking a plurality of rain tank (72). At this time, it is preferable that the drain pipe 71 penetrates the upper portion of the rain tank 72 located at the top of the stacked rain tanks 72 as shown in FIG. 4, and when the rain tanks 72 are stacked as shown in FIG. 4. It is preferable that the side and lower portions of the rain tanks 72 overlapping each other are not covered with the sealing cover 82 and the nonwoven fabric 81.

Meanwhile, the upper part of the rain catcher 100 and the non-point pollution purification unit 20 can be configured to be opened and closed as shown in FIG. 7, so that foreign matters accumulated on the first screen 11 and the second screen 21 are easy. Can be cleaned.

In addition, the present invention can install the first and second wells (91, 92) on both sides of the rain tank 72, which is to ensure the space to remove the foreign matter deposited in the interior of the drain pipe (71) , Upper portions of the first and second wells 91 and 92 may be configured to communicate with the ground, and the upper portion may be configured to be opened and closed through a lid (not shown).

In addition, the initial excellent non-point pollution treatment apparatus of the present invention may be made of a configuration as shown in FIG. Figure 7 is consistent with most of the configuration of Figure 6, the other configuration of the cover 90 that can open and close the top of the non-point pollution purification unit 20 and the initial excellent water collecting expansion unit 30 and the initial excellent separation unit The difference between the configuration of the excess water blocking portion provided on one side of the inlet pipe 41 on the side of (10) and the configuration of the sediment receivers 63 and 64 provided on the lower portion of the initial excellent water collecting expansion portion 30 is further added. .

The cover 90 prevents foreign matter or rainwater from being introduced directly into the non-point pollution purification unit 20 and the initial excellent catchment expansion unit 30. Therefore, the circumference of the cover 90 is preferably finished by rubber packing to ensure watertightness, and the sediment receiver 63 of the second screen 21 of the non-point pollution purification unit 20 and the initial excellent water collecting expansion unit 30 is provided. 64) is detachably configured for a cleaning request.

The excess excellent blocking unit is configured as the configuration of the 52 and 53, and the same configuration as the blocking unit of FIG. That is, it usually has an action force to open the inlet pipe 41, and if the buoyancy force is greater than the action force to open the inlet pipe 41 blocks the inlet pipe 41. Therefore, as shown in FIG. 7, when the water level S of the initial excellent separation unit 10 is about, the operation force to open the inlet pipe 41 is greater than the buoyancy force, so the rainwater continuously flows into the non-point pollution purification unit 20. However, when the rainwater exceeds the capacity of the initial excellent separation unit 10 as shown in the bottom of FIG. 7, the excess water blocking unit is larger than the inlet pipe ( Block 41) does not flow rainwater to the non-point pollution purification unit 20 anymore.

Such a structure no longer flows into the non-point pollution purification unit 20 except for the initial excellent water. In other words, if the rainfall continues, the initial excellent separation unit 10 continuously maintains the saturation state of the rainwater, so no further rainwater flows into the non-point pollution purification unit 20. Therefore, even if all of the initial excellent rain in the non-point pollution purification unit 20, the rain is no longer introduced into the non-point pollution purification unit 20, and when the rainfall is finished, the rainwater of the initial rainwater separation unit 10 gradually dries and then only the inlet pipe ( The configuration of the 54 to open 41 is increased than the force of the buoyancy to open the inlet pipe 41 to the original position.
