Description

{Initial precipitation treatment system with Non-point Source Pollutants}

The present invention relates to a non-point pollution initial good treatment system, and more particularly, it relates to a pollution-free initial pollutant treatment system capable of reducing environmental pollution by discharging an excellent initial concentration of 5 mm to 10 mm to a sewage treatment plant, Because it does not send all stormwater to the sewage treatment plant, it does not need any additional expansion to increase the treatment capacity of the sewage treatment plant. It provides a budget saving effect, and the opening / closing means for managing the initial storm to be sent to the sewage treatment plant The present invention relates to a non-point pollution initial excellent treatment system capable of storing the date and time sent to the sewage treatment plant in a database and systematically managing the date and time.

Nonpoint pollutants are also commonly referred to as non-specific pollutants, cotton pollutants, and mobile pollutants.

Unlike a point pollution source having a specific discharge path, a nonpoint pollution source refers to a place or area that generates nonpoint pollutants through an unspecified discharge path, such as urban road drains or agricultural drainage.

Non-point pollutants are pollutants that come out along with surface runoffs when they are exposed to rain. These include fertilizers, pesticides, soil sprinkling plants, housing spills, traffic pollutants, dust and garbage in urban areas, Water, and air pollutants.

In general, initial rainfall from non-point sources includes various pollutants, bacteria, and bacteria, and more and more contaminants will emerge in the future.

Non-point pollution abatement facilities that reduce such non-point pollutants are largely divided into natural facilities and equipment-type facilities.

Equipment type facilities are divided into vortex type, screen type, filtration type, etc. Such apparatus type facilities are installed in the middle of the gut pipe and rainwater is flowed in when rainfall, so that the pollutants are removed and discharged.

This type of facility should be installed in the basement so that it should be connected to the gutters, and the pollutants collected at the bottom of the facility should be periodically sucked into the vacuum cleaner and dredged.

Periodic dredging requires a large amount of manpower and a work vehicle, and when the cleaning cycle is missed, the collected pollutants are washed away by the decaying or subsequent rainfall, and the role of the nonpoint pollution abatement facility becomes unclear.

It is estimated that the pollutants nitrogen (N) and phosphorus (P) causing eutrophication of rivers and lakes are 75% and 50% of total pollution loads, respectively.

In addition, non-point pollutants are increasing rapidly year by year, causing difficulties in the management of the water supply of the government and promotion of river purification projects.

In particular, non-point pollutants in urban areas are representative outflows from combined sewer effluents (CSOs), roads, sidewalks, parking lots, etc. that flow out through combined sewer pipes, As the impermeable layer increases, the high concentration eigenvalue flows into the river in a short time during rainfall.

As a result, there is a risk that the river ecosystem will be destroyed due to the loss of function of river water which should be used as ecological water and hydrophilic water. Therefore, in order to improve the river water quality and river ecological environment, Non-point pollutants generated during purification and rainfall should be treated simultaneously.

However, since the conventional techniques have a complicated structure, the apparatus is complicated and requires a large installation and maintenance cost, and the durability of the apparatus is poor. Therefore, the structure of the processing apparatus is simplified while the processing efficiency is improved And it is necessary to develop the technology for treatment of nonpoint pollutants.

FIG. 1 is an overall configuration diagram of a non-point contaminated initial good treatment system according to a first embodiment of the present invention.

FIG. 2 is a general configuration diagram of the non-point pollution initial good treatment system according to the first embodiment of the present invention, viewed from another angle.

1 and 2, the non-point pollution initial good treatment system includes an excellent pipe 100, a living sewage pipe 200, a collector 300, a water level measuring device 400, an opening / closing means 500, (600), and a rainwater sensing control device (700).

Fig. 1 is a schematic configuration diagram as viewed from above, and Fig. 2 is a schematic configuration diagram as viewed from a side.

Conventional new city sewer system uses polluted living sewage and stormwater using different conduits, and rainwater is sent to charger and contaminated living sewage is sent to sewage treatment plant.

However, the initial 5 ~ 10mm of rainwater has a high pollutant concentration, which causes serious contamination of the river when it is immediately sent to the river.

However, when all rainwater is sent to the wastewater treatment plant, it exceeds the treatment limit, and it should be expanded to increase the treatment capacity of the sewage treatment plant.

Accordingly, in the present invention, a system for treating rainwater having an initial concentration of 5 to 10 mm with a high concentration of contaminants has been proposed through the above-described structure.

In the following, the constituent means described above will be specifically described.

The gutter tube (100) is connected to the river and is configured to introduce the storm into the river (110).

At this time, the catch 120 is formed at one side of the gutter.

In addition, the living sewage pipe 200 is connected to the sewage treatment plant 210 to introduce the domestic sewage into the sewage treatment plant.

In addition, the collecting unit 300 is formed below the collecting hole 120 of the excellent tube to temporarily store and store the initial excellent flowing through the collecting hole 120.

At this time, as shown in FIG. 2, the lower part of the water collecting part 300 is formed to be inclined so as to be inclined in one direction, so that foreign substances naturally included in the initial water gathering are collected in the filter material.

The dust collector 300 is formed of high-strength concrete to have a predetermined thickness, thereby preventing breakage of the filter medium and the water level measuring device formed in the internal space from external impacts.

As shown in Figs. 1 and 2, the water level measuring apparatus 400 is installed inside the water collecting unit to measure the water level.

At this time, mutual signals are exchanged through wired or wireless communication to provide the water level sensing signal to the rainwater sensing control device.

The water level measuring apparatus is installed in the inside of the water collecting compartment. For example, the water level measuring apparatus includes means for detecting the water level in the cylindrical cover (for example, Electrode rod) is positioned so as not to be influenced by a malfunction caused by pollutants flowing into the collection tank.

1 and 2, the opening / closing means inserting opening 130 is formed at one side of the excellent tube (a position spaced apart from the catching opening 120 by a predetermined distance) . That is, the opening / closing means is positioned in the opening / closing means insertion port 130.

At this time, the opening / closing unit 500 is installed at one side of the initial storm drain pipe 600 at a position spaced apart from the condensate collecting unit 500 so as to be opened or closed according to a control signal of the rainwater detection control unit. A control signal is received from the rainwater detection control device through wired or wireless communication to perform an opening or closing operation according to a control signal (an open signal, a closing signal) of the sensing control device.

Although the opening / closing means 500 is preferably an on-off valve, the present invention is not limited to the ON / OFF valve. Any means that can be opened or closed by the control signal of the rainwater detection control device 700 is applicable.

1 and 2, one side of the initial storm drain pipe 600 is connected to the opening / closing means 500, and the other side is connected to the living sewage pipe 200.
When the opening / closing means is opened, the initial stormwater flowing into the initial storm drain pipe 600 flows into the living sewer pipe 200, .

The rainwater sensing control apparatus 700 of the present invention provides an open signal to the opening / closing means 500 when acquiring a water level sensing signal (first, second and third water level sensing signals) from the water level measuring apparatus 400 And opens the opening / closing means 500 to introduce the initial storm that flows into the grate 100 into the initial storm drain pipe 600. Thereafter, the initial stormwater flowing into the initial storm drain pipe 600 flows into the sewage treatment plant 210 through the domestic sewer pipe 200.

In addition, the rainwater detection control apparatus 700 counts the water level rise time according to the water level detection signal, sets the opening time of the opening / closing means 500 according to the counted water level rise time, 500 to close the opening and closing means 500 to block the stormwater flowing into the storm drain pipe 100 from flowing into the living sewage pipe 200 through the initial storm drain pipe 600.

The initial storm means the initial 5 ~ 10mm rainfall at the time of the initial rainfall.

Therefore, it is necessary to judge whether the initial rainfall is good at the time of heavy rainfall, to judge the initial rainfall in the continuous rainfall where the rainfall of 5 mm drops two days ago and the rainfall of 5 mm drops today, and whether to send the determined rainfall to the sewage treatment plant or to the river The rainwater detection control apparatus is configured to determine the rainwater detection apparatus.

In addition, according to an additional aspect, the present invention further includes a runner jaw 800 inside the water collecting pipe immediately adjacent to the opening / closing means 500, thereby preventing the initial storm from flowing into the river.

In other words, a lot of stormwater flows into the stormwater tube 100 in a short time. In this case, most initial stormwater flows into the stormwater system, but some initial stormwater is excessive.

If the opening / closing means 500 is opened, the initial storm that has passed the storm drainage will flow into the sewage treatment plant through the initial storm drainage pipe 600. However, if the opening / closing means 500 is closed, the initial stormwater flows into the river. In order to keep this initial storm for a while, a twin tuck 800 is constructed.

Therefore, in order to temporarily prevent the early storm from being collected in the storm water pipe until the opening of the opening and closing means and to prevent the storm water from flowing into the river, the ridge tuck 800 is formed at a height of, for example, about 5 cm to 15 cm will be.

Further, according to another additional aspect, as shown in Fig. 2,

A collecting outlet pipe 900 formed on the bottom of the collecting compartment to discharge the initial storages stored in the collecting compartment 300 to the sewage disposal plant through the initial storm drainage pipe 600 or the living sewage pipe 200, and,

A filter medium 910 formed to filter the initial rainwater on the underside of the water collecting pipe to which the water recovery pipe is connected,

And a filter net 920 formed in the collecting port to primarily filter the initial storm that flows into the collecting net.

The initial storm that has been stored in the storm collector 300 through the storm drain pipe 900 is discharged to the outside of the storm sewer (sewage treatment plant or the ground) naturally over time.

Then, the filter medium 910 is used to filter the initial rainwater discharged to the collection pipe.

For example, a filter medium such as gravel, sand, zeolite, activated charcoal, crushed stone and the like is laid on the collecting floor so that the pollutants contained in the initial rainwater are firstly filtered and discharged to the collecting discharge pipe.

Further, the filter net 920 is characterized by primarily filtering the initial storm that flows into the catching port.

FIG. 3 is a schematic view of a level measuring apparatus 400 for a non-point contaminated initial good treatment system according to the present invention.

As shown in Fig. 3, the water level measuring apparatus 400 includes:

A plurality of air holes (410) formed around the outer surface of the water level measuring apparatus at regular intervals;

A plurality of water holes (420) formed around an outer surface of the level gauge to induce a smooth flow of water;

A plurality of electrode bars 430 formed at different lengths in the water level measuring apparatus and sensing the water level;

And a water level measurement processing unit 440 connected to one side of the electrode and generating a water level sensing signal according to the water level sensed by the electrode and providing the water level sensing signal to the rainwater sensing controller.

Specifically, the water level measuring apparatus has, for example, a cylindrical bar-shaped outer appearance, and a plurality of air holes 410 are formed at regular intervals along the outer surface.

The air hole 410 is for allowing the initial rainwater to flow into the water level measuring apparatus 400.

Specifically, the electrode rod 430 sensing the water level is installed inside the water level measuring apparatus 400. Therefore, it is possible to detect the water level by the electrode when the initial storm stored in the water collecting system is introduced into the cylindrical bar-shaped water level measuring apparatus.

The air hole 410 is for a smooth introduction of the initial clearance into the cylindrical bar-shaped level gauge.

The water holes 420 are formed around the outer surface of the water level measuring device to induce a smooth flow of water to the inside and the outside of the water level measuring device.

Specifically, at least a pair of water holes of the plurality of water holes 420 are formed in the same horizontal position on the level measuring apparatus so that the initial storages can flow smoothly through the inside and outside of the water level measuring apparatus.

That is, as shown in Fig. 3, the water holes 420 are formed in a pair of water holes A and B at the same horizontal position on the cylindrical rod-shaped water level measuring apparatus.

This is because the electrode of the present invention can detect the level of water by a certain amount of water flow, and the water hole 420 is a structure for guiding the smooth flow of water to the inside and the outside of the water level measuring apparatus.

As shown in FIG. 3, by forming the water holes A and B on the same horizontal line, it is possible to provide a smooth flow velocity to the inside and the outside of the water level measuring apparatus.

In addition, the size of the water holes is formed larger than the size of the air holes to induce the flow of water.

The plurality of electrode rods 430 are for detecting the level of the initial rainwater in the collecting column,

A first electrode rod 431 formed vertically;

A second electrode rod 432 spaced apart from the first electrode rod by a predetermined distance and formed to be longer than a length of the first electrode rod;

And a third electrode rod 433 spaced apart from the second electrode bar by a predetermined distance and formed to be longer than the length of the second electrode bar.

As the initial storm flows into the stormwater collector 300, the level of the initial stormwater stored in the stormwater collector 300 rises, and the third electrode rod having the longest length first detects the initial stormwater, The second electrode rod senses the water level, and finally the first electrode rod senses the water level.

The water level measurement processing unit 440 provides a water level sensing signal to the rainwater sensing control unit when sensing the water level by the electrode. When the water level of the first electrode is sensed, the first water level sensing signal is transmitted to the rainwater sensing control unit. When the level of the second electrode is detected, the second level sensing signal is transmitted to the rainwater sensing control device, and when the level of the third electrode is sensed, the third level sensing signal is transmitted to the rainwater sensing control device.

On the other hand, as shown in Fig. 8, the rainwater detection control apparatus 700 of the present invention includes:

An open signal providing unit 710 for providing an open signal to the opening and closing means 500 when acquiring the level sensing signal from the level measuring apparatus 400;

A user opening time setting unit 720 for setting the opening time of the opening / closing means according to the setting of the user;

A water level proportional opening time setting unit 721 for setting the opening time of the opening / closing means in proportion to the rising time of the initial storm that flows into the house correction;

A period proportional opening time setting unit (722) for setting an opening time of the opening / closing means in proportion to a period from a previous last rainfall occurrence time to a current rainfall occurrence time;

An open time selection unit 723 for selecting any one of the open time set by the user open time setting unit 720, the water level proportional open time setting unit 721, and the period proportional open time setting unit 722 as the open time;

And a closed signal providing unit 730 for providing a closing signal to the opening / closing means 500 when the opening time selecting unit 723 elapses the selected opening time.

The open signal providing unit 710 provides an open signal to the open / close means 500 when the level detecting device 400 obtains the level detecting signal, and the opening / closing means 500 is opened by the open signal The initial storm flowing in the storm sewer 100 flows into the sewage treatment plant through the initial storm drain pipe 600.

The water level sensing signal includes first, second and third water level sensing signals transmitted from the water level measuring device 400 every time the first, second, and third electrodes of the water level measuring device 400 detect the water level.

The level sensing signal used to provide the opening signal to the opening and closing means 500 may be a first level sensing signal, a second level sensing signal, or a third level sensing signal depending on the user's setting.

That is, the open signal providing unit 710 provides an open signal to the opening and closing means when acquiring any one of the first, second and third water level sensing signals.

The user opening time setting unit 720 is for setting the opening time of the opening / closing means according to the setting of the user, and is a means for the user to set the opening time in accordance with the scene situation.

Information about the open time set by the user is stored in the initial good management database 760.

The water level proportional opening time setting unit 721 is a means for setting the opening time of the opening / closing means in proportion to the rising time of the initial storm that flows into the water collecting system.

To this end, the water level proportional opening time setting unit 721 starts counting the time of receiving the second water level sensing signal transmitted when the water level is sensed by the second electrode, and when the water level is sensed by the first electrode, The counting is terminated upon receipt of the detection signal.

Then, the water level proportional opening time setting unit 721 sets the opening time of the opening / closing means in accordance with the counted time, and the setting is a setting of the opening / closing means opening time proportional to the counted time.

For example, if the rise time of the water level is long, the opening and closing means opening time becomes proportionally longer. That is, when the rising time of the number of the initial storages stored in the collection is small, the opening / closing means is opened for a long time.

Conversely, if the rise time of the water level is short, the opening and closing means opening time is also shortened proportionally.

More specifically, when the water level rises at the position L1 where the second electrode rod 432 of FIG. 4 is in the position where the second electrode rod 432 can sense the water level (at this time, the water level measuring apparatus 400 is at the second water level The water level proportional opening time setting unit 721 starts time counting and sets the water level proportional opening time setting unit 721 to the water level control unit 700. The water level proportional opening time setting unit 721 starts the time counting, The time counting is ended.

At this time, when the counted time, that is, the time taken until the water level rises from L1 to L2 is T, the opening / closing valve opening time is determined in proportion to T (seconds).

For example, if 0 <T ≤ 5, the valve opening time is set to 1 minute. If 5 <T ≤ 10, the valve opening time is set to 2 minutes. If 10 <T ≤ 15, the valve opening time is set to 3 minutes.

The unit of T value in the above example is seconds, and the valve opening time of 1 minute, 2 minutes and 3 minutes according to the illustrated T can be changed according to the on-site conditions.

The opening time of the opening / closing means may be set in proportion to a period from the immediately preceding rainfall occurrence point to the current rainfall occurrence point.

The term proportional opening time setting unit 750 sets the opening time of the opening / closing means in proportion to the period from the last rainfall occurrence point to the current rainfall occurrence point .

That is, if the period from the last rainfall occurrence to the present rainfall occurrence is long, the open time of the open / close valve becomes longer, and if the period from the last rainfall occurrence time to the present rainfall occurrence time is short, will be.

As shown in FIG. 5, when the date from the last rainfall occurrence point to the current rainfall occurrence point is D, the open / close valve opening time is determined according to the D value.

For example, as shown in FIG. 5, when the previous rainfall occurrence time point is D1, the current rainfall occurrence time point is D2 or the previous rainfall occurrence time point is D2, the current rainfall occurrence time point is D3, or the previous rainfall occurrence time point is D3, When the time is D4, the period of D1 to D2 is 11 days → the valve opening time is 5 minutes, the period of D2 to D3 is 6 days → the valve opening time is 2 minutes, the period of D3 to D4 is 2 days → valve opening time The opening time of the opening / closing means is set in proportion to the period from the time of the last rainfall occurrence to the time of the current rainfall occurrence such as 1 minute.

That is, if the period from the immediately preceding rainfall occurrence time to the present rainfall occurrence time is ΔD, if the open / close valve opening time is 1 minute and 5 ≦ ΔD <10, then the open / close valve opening time is 2 minutes and 10 ≦ ΔD &Lt; 20, the open / close valve opening time is set to 5 minutes.

The opening / closing valve opening time value according to the above-mentioned? D can be set to be changeable according to the on-site condition.

The open time selection unit 723 selects any one of the open time set by the user opening time setting unit 720, the water level proportional open time setting unit 721, and the period proportional open time setting unit 722 as the open time .

That is, the user opening time setting unit 720, the water level proportional opening time setting unit 721, and the period proportional opening time setting unit 722 set their respective opening times.

The user must select one of the open time set by the user open time setting unit 720, the water level proportional open time setting unit 721, and the period proportional open time setting unit 722 as the final open time, 723).

The closing signal providing unit 730 closes the opening and closing means 500 to the opening and closing means 500 when the opening time selected by the opening time selecting unit 723 has elapsed, So that the storm flows into the river 110.

In addition, according to yet another additional aspect, the rainwater detection and control apparatus 700 further includes a rainfall meter 770.

When the rainfall amount measured by the rainfall amount meter 770 reaches a predetermined target rainfall amount value, the rainwater detection control device 700 immediately provides an open signal to the opening / closing means to open the opening / closing means.

On the other hand, according to still another additional aspect, the rainwater detection control apparatus 700 includes:

An initial good management database 760 storing the open time information set by the user, the open time information matched to the water level rise time, and the target rainfall amount information.

The open time information matched with the water level rise time may be table information that matches the counted water level rise time and the corresponding open time.

The target rainfall amount information is a rainfall flow rate value used by the rainwater detection and control device 700 to immediately provide an open signal to the opening and closing means when the rainfall reaches the target rainfall amount value measured by the rainfall amount meter, The control device 700 firstly immediately opens the opening / closing means by providing an opening signal to the opening / closing means.

In addition, the time of occurrence of the level value set in the house correction at the beginning of the rainfall, the opening date and time of the opening and closing means, and the like can be stored in the initial excellent management database 760.

According to yet another aspect of the present invention, the non-point pollution initial good treatment system of the present invention may further comprise a pollution judging means (1000) on one side of the initial poor discharge pipe (600).

The pollution determining means 1000 measures the degree of contamination of the initial stormwater flowing into the sewage treatment plant through the initial storm drainage pipe 600. When the measured degree of contamination of the initial stormwater is equal to or less than the set reference contamination value, Lt; / RTI &gt;

That is, even if the initial opening of the sewage treatment plant through the initial storm drain pipe 600 is not so severe, even if the set opening time has not elapsed, the opening / closing means 500 is closed, 110). &Lt; / RTI &gt;

In this case, the opening / closing means 500 is not closed even when the closing signal due to the elapse of the set opening time is received from the rainwater detection control device 700, and is closed when receiving the closing signal from the pollution judgment means 1000 .

That is, the pollution judging means 1000 prevents unnecessary pollution from flowing into the wastewater treatment plant, and at the same time, the pollution judging means 1000 prevents the contaminated initial pollution from flowing into the open / 500 from being closed.

As a result, according to the present invention, initial rainfall (an excellent initial concentration of 5 mm to 10 mm with high concentration of pollutants) having a nonpoint source occurring at the beginning of rainfall occurs at the beginning of rainfall is sent to the sewage treatment plant, By closing the opening and closing means of the city, it is possible to reduce the environmental pollution by discharging the clear storm to the river. Since only the initial storm having the nonpoint pollution source is sent to the sewage treatment plant, there is no need to additionally increase the capacity of the sewage treatment plant. .

Also, by storing information on precipitation forecasts for each day of the Meteorological Agency, the time of occurrence of the water level value set in the house modification at the beginning of rainfall, the opening date and time of opening and closing means, etc. in a database and systematically managing the opening time, So that it can exhibit an effect of being operated in a flexible manner.
