Description

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

The present invention relates to an initial excellent non-point pollution treatment apparatus for separating and purifying the initial excellent water containing a large amount of non-point pollutants during rainfall.

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 reach 44.5% of nonpoint sources, indicating that nonpoint sources have a significant effect on water pollution. The watersheds of the four major watersheds are similar to the Geum, Nakdong, and Youngsan rivers. It is expected to show a pattern. 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 maintenance costs are rising.

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 provide an initial excellent non-point pollution treatment apparatus according to the present invention for separating and purifying the initial excellent water to reduce water pollution.

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; A first screen provided above the initial excellent separation part and separating foreign matters; A non-point pollution purification unit equipped with a filter agent for filtering non-point contaminants contained in the rainwater by receiving rainwater separated from the first screen of the initial excellent separation unit; More rainwater is introduced than rainwater discharged by the non-point decontamination unit, and when the excess capacity of the non-point decontamination unit is exceeded, the rainwater is continuously stored and induced. An initial excellent catchment expansion unit for supplying the non-point pollution purification unit; It is achieved by the initial excellent non-point pollution treatment device, characterized in that it comprises a; block to block the rainwater supply from the initial excellent separation unit when the excellent storage capacity of the initial excellent water collection expansion unit.

According to the initial excellent non-point pollution treatment apparatus according to the present invention, since only the initial excellent water is separated / purified from each storm 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.

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

The initial excellent non-point pollution treatment apparatus according to the present invention is composed of an initial excellent separation unit 10 and a non-point pollution purification unit 20, and the non-point pollution purification unit to separate and purify a large amount of initial excellent water. Although the initial excellent catchment expansion unit 30 may be further provided near (20), it is preferable to provide the non-point pollution purification unit 20 and the initial excellent catchment expansion unit 30 in one space.

Specific configuration of the present invention, the initial excellent separation unit 10 provided on the inner surface of the rain receiver 100 corresponding to the direction in which the rainwater 300 is introduced;

A first screen 11 provided at an upper portion of the initial excellent separation unit 10 to separate foreign substances;

Non-point pollution purification provided with filter agent 22 (eg, sand) for filtering rain-point contaminants contained in rainwater by receiving rainwater separated from the first screen 11 of the initial excellent separation unit 10. Part 20;

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 the water 20;

It may include; a blocker for blocking the rainwater supply from the initial rainwater separating unit 10 when the rainwater storage capacity of the initial rainwater collecting unit 30 is exceeded.

Here, the non-point pollution purification unit 20 separates the second screen 21 for separating 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 blocking It is preferable to comprise a floating port 52 attached to one side of the plate 51, the upper portion of the initial excellent water collecting expansion portion 30 and the non-point pollution purification portion 20 is removable and can be opened and closed the cover 90, 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. 1, the initial excellent separation part 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 to the outside (as shown in FIG. 1). 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 1, 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 1 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 part 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 until the initial excellent catchment expansion unit 30 is exceeded). Case) the inlet pipe 41 is blocked.

On the other hand, the rainwater receiving unit 100 and the top of the non-point pollution purification unit 20 can be opened and closed as shown in FIG. Therefore, foreign matters accumulated on the first screen 11 and the second screen 21 can be easily cleaned.

The present invention may be configured as shown in FIG. Figure 4 is consistent with most of the configuration of Figure 1, 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 part is the same structure as the structure of the blocking part of FIG. That is, it has an action force to open the inlet pipe 41 normally, and if the force of the buoyancy is greater than the action force to open the inlet pipe 41 blocks the inlet pipe 41. Therefore, as shown in FIG. 4, 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 that the rainwater continuously flows into the non-point pollution purification unit 20. However, when the rainwater exceeds the storage capacity of the initial excellent separation unit 10 as shown in the bottom of Figure 4, the excess water blocking unit is the excess water blocking unit because the force of buoyancy is greater than the action force to open the inlet pipe 41 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 over, the rainwater of the initial rainwater separation unit 10 gradually dries and then only flows in. The configuration of the 54 to open the pipe 41 is increased than the force of the buoyancy to open the inlet pipe 41 to the original position.

Unexplained sign 401 is boundary stone, 500 is India.

On the other hand, the present invention increases the amount of movement to the non-point pollution purification unit 20 of the rain containing a non-point source by forming a plurality of communication pipes (62, 62a, 62b) in the partition wall 61 as shown in FIG. This can help to increase the initial cleanup throughput.

Although the present invention has been described in connection with the preferred embodiment, those skilled in the art will be able to easily make various changes and modifications without departing from the essential characteristics of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation, and the true scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the equivalent scope are included in the present invention.
