Description

Non-point source treatment structure {APPARATUS FOR PURIFICATION NONPOINT POLLUTION SOURCE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of environment, and more particularly, to a non-point source treatment structure for efficiently purifying contaminated water contaminated by non-point source generated from road surface, construction site and the like.

Sources of pollutants are classified into point sources and nonpoint sources based on whether their outlets are specified in a specific location.

Non-point source is a case where the pollutant is discharged through the discharge port of a specific place, such as sewage treatment plant, wastewater treatment plant of industrial plant, livestock, manure, leachate and the like.

Non-point source is a case where the discharge port of pollutants cannot be specified, such as pollutants accumulated on the top of roads and bridges, fine dust such as vehicle exhaust gas and tires, and pollutants accumulated on the surface of construction sites such as road farmland For example, these pollutants are a representative cause of water pollution because it is introduced into the stream with rainwater (rain water) during rainy weather.

These nonpoint sources are non-specific pollutants as described above, and since most of them are washed and drained by rainwater, they are affected by weather conditions, environmental conditions, geology, and terrain, which are difficult to artificially control.

Therefore, the difference in daily nonpoint source drainage amount between the nonpoint source and the season is large, and prediction and quantification are very difficult.

In addition, the nonpoint source can be discharged sufficiently by a large amount of rain, so a large amount of nonpoint source must be treated at a time.

Therefore, as a countermeasure for treating a nonpoint source, there may be various methods. However, in the current situation, a nonpoint source is installed in a sedimentation method in which a nonpoint source, that is, drained with rain, is precipitated and then discharged. Is processing.

However, in the present situation, the sedimentation method can economically handle a large amount of nonpoint source, and it is easy to manage, maintain, and repair irregular and nonspecific point source, but it simply precipitates contaminated water contaminated by nonpoint source. Therefore, it has the following problems.

In other words. In order to effectively treat the nonpoint source, it is necessary to have a sufficient settling time, so that the nonpoint source takes a long time.

In addition, due to the flotation of fine sludge, the sludge caused by the agitation caused by the drainage of precipitated purified water or the inflow of contaminated water contaminated by nonpoint source, etc. have.

In addition, secondary sedimentation sources are generated due to prolonged sedimentation of the sludge, and there is a limit in purifying contaminated water sufficiently, and it is difficult to treat the precipitated sludge.

In addition, in order to discharge the precipitated sludge, the treatment of non-point source must be stopped from time to time, and a lot of time and cost are required for maintenance and repair due to discharge of the precipitated sludge.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a non-point source treatment structure that can more effectively treat the non-point source by the precipitation method.

The present invention to solve the above problems is the storage tank 10 having a settling space (10A) so that the contaminated water contaminated by non-point source can be discharged after precipitation; A scraper (20) installed in the settling space (10A) of the storage tank (10) to scrape the sludge (2) which is a non-point pollution source in the contaminated water; A filtration unit (30) installed to filter the sludge (2) and allow the filtered water to flow into the settling space (10A) of the storage tank (10); It presents a non-point source treatment structure comprising a; guide portion 40 for guiding the sludge 2 collected by the scraper 20 to the filtration unit 30.

The filtration unit 30 may be installed above the storage tank 10.

The filtration unit 30 may be installed at an inlet side of the inlet and outlet of the storage tank 10.

The filtration unit 30 includes a filtration tank 32 having a precipitation space 10A of the storage tank 10 and a filtration space 32A connected to the guide unit 40; And a filtration member 34 installed to be detachable from the filtration space 32A of the filtration tank 32 so as to filter the sludge 2.

The guide part 40 may include a pump 44 for pumping the contaminated water in the precipitation space 10A of the storage tank 10 to the filtration part 30.

The storage tank 10 may further include a dust chamber 50 in which the sludge 2 is collected by the scraper 20 and connected to the guide portion 40.

The dust chamber 50 may have an opening 52 through which the sludge 2 collected by the scraper 20 is introduced and can be covered by the scraper 20.

The storage tank 10 may be constructed by a precast method.

The storage tank 10 is assembled up and down to form a cavity having both ends opened, each of the upper and lower members (100, 110) are installed so as to be connected to each other along the opening direction of the cavity; And a pair of finishing members 120 covering the open both ends of the cavity formed by the upper and lower members 100 and 110, respectively, to form the precipitation space 10A.

At least one of the upper member 100 has a guide hole so that the guide portion 40 can be penetrated, and a filtrate hole to allow the filtrate to flow into the settling space 10A of the storage tank 10. Can be formed.

At least one of the upper members 100 may be integrally formed with a power pack member in which a driving unit for driving the scraper 20 is installed.

The storage tank 10 may further include at least one partition member 140 partitioning the precipitation space 10A.

The partition member 140 may have at least one opening to allow the polluted water to communicate.

The partition member 140 may be formed integrally with the upper member 100 and the upper partition wall portion 140A, and the lower member 110 may be manufactured integrally with the upper partition wall portion 140A and the partition member ( A lower partition wall portion 140B constituting the 140 may be included.

In the present invention, the sludge in the storage tank is precipitated, and the sludge in the storage tank is scraped and filtered by a scraper, so that the non-point source treatment by the precipitation method is very excellent.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the non-point source treatment structure according to the present invention, the storage tank 10 having a settling space (10A) so that contaminated water contaminated by the non-point source can be discharged after the precipitation process, and in the contaminated water The scraper 20 installed in the sedimentation space 10A of the storage tank 10 and the sludge 2 are filtered to collect the sludge 2 which is a non-point pollution source, and the filtered water is filtered out of the sedimentation space of the storage tank 10. It comprises a filtration part 30 provided so that it may flow into 10A, and the guide part 40 which guides the sludge 2 collected by the scraper 20 to the filtration part 30. As shown in FIG.

That is, basically, the sludge 2, which is a non-point pollutant of contaminated water, is precipitated in the sedimentation space 10A of the storage tank 10 so that the sludge 2 remains in the storage tank 10, and only the purified water is discharged after the sludge 2 is precipitated. To treat the non-point source.

Therefore, the contaminated water only needs to be contained in the sedimentation space 10A of the storage tank 10, so that a large amount of nonpoint source can be economically treated, and the treatment and management of irregular and nonspecific nonpoint source is easy. .

In addition, after the sludge 2 is collected by the scraper 20 to one side, the collected sludge 2 is caught by the filtration unit 30.

Therefore, as the sludge 2 is removed to some extent by the filtration unit 30 and precipitated in the settling space 10A, the non-point source treatment efficiency by the sedimentation method in the storage tank 10 is very excellent. have.

Specifically, as the amount of precipitation in the settling space 10A of the storage tank 10 is significantly reduced, it is possible to reduce the settling time, that is, non-point source treatment time.

In addition, since the fine sludge 2 may also be caught by the filtration unit 30 and the amount of precipitation is small, the decrease in precipitation rate due to the sludge 2 floating may be prevented.

In addition, since the sludge 2 precipitated in the storage tank 10 can be immediately discharged by the scraper 20 and the guide portion 40, the secondary pollution source can be prevented due to the long-term precipitation of the sludge (2). have.

In addition, for the discharge of the precipitated sludge 2, it is not necessary to stop the inflow and drainage of the contaminated water, it is possible to effectively reduce the time and cost of maintenance and repair due to the discharge of the precipitated sludge (2).

Furthermore, the filtration unit 30 only needs to filter the sludge 2 collected by the scraper 20, so that the required filtration capacity of the filtration unit 30 is smaller than that of the sedimentation water contaminated by the storage tank 10. to be. Therefore, as compared with the manner in which the whole contaminated water is filtered by the filtration unit 30, the treatment by the filtration unit 30 according to the present invention can further obtain the effect that it is quite economical.

In addition, since the filtration unit 30 filters only the sludge 2 collected by the scraper 20, the filtration capacity of the filtration unit 30 can be predicted over time, so that the filtration unit 30 is maintained, The effect of easy maintenance can be further obtained.

Here, the filtration unit 30 may be installed anywhere, but it is provided so that the contaminated water together with the guide unit 40 close to the inlet of the storage tank 10 first introduced into the settling space 10A of the storage tank 10. Is more effective.

That is, when the contaminated water flows into the settling space 10A of the storage tank 10 through the inlet of the storage tank 10, a considerable amount of the sludge 2 in the contaminated water by gravity is inlet and the storage tank 10 of the storage tank 10. Is precipitated at the inlet side of the storage tank (10) of the outlet portion of.

Therefore, the sludge 2 can be collected directly by the scraper 20 at the inlet side of the storage tank 10, and the collected sludge 2 can be guided to the filtration unit 30.

Therefore, since the sludge 2 can be collected and guided in the shortest moving path, the overall structure such as piping can be simplified, and the pumping capacity of the guide part 40 can be minimized.

In addition, when the sludge 2 floats due to contaminated water agitation by the scraper 20 or the like during the dust collection process of the sludge 2 by the scraper 20, the suspended sludge 2 is guided by the scraper 20. It is not easy to collect as 40. However, by collecting the sludge 2 directly at the inlet side of the storage tank 10 as described above, since the floating of the sludge 2 can be suppressed to the maximum, the efficiency of dust collection of the sludge 2 can be increased. And according to this, the sludge 2 can be collected at a time, the filtration efficiency in the filtration unit 30 is also improved, and the precipitation efficiency in the settling space 10A of the storage tank 10 can also be excellent.

In addition, the filtration unit 30 may be installed anywhere on the side, the bottom, and the upper side of the storage tank 10, but it is more effective to be installed above the storage tank 10 as shown.

That is, after filtration of the sludge 2 in the filtration unit 30, the filtered water can flow into the settling space 10A of the storage tank 10 by free fall. Therefore, since there is no need for a separate power source for flowing the filtered water into the settling space 10A of the storage tank 10, it is structurally simple and economical in terms of construction, maintenance, and maintenance.

Such a filtration unit 30 may take various structures, and as an example, the filtration tank 32 having the filtration space 32A connected to the settling space 10A of the storage tank 10 and the guide portion 40 as illustrated. ) And a filtration member 34 installed to be detachable in the filtration space 32A of the filtration tank 32 so that the sludge 2 can be filtered, thereby enabling a simple structure.

Here, the filtration tank 32 may be one or two or more, depending on the size of the storage tank 10, the position and the number of the inlet portion of the storage tank 10, one filter tank (32) 34) can be installed.

As described later, the filtration tank 32 may be more preferably manufactured by the precast method together with the storage tank 10.

As described above, when the filtration unit 30 is installed above the storage tank 10, the filtration tank 32 may have an opening 32B for filtering water at a bottom thereof so that the filtration water may fall freely. In this case, one or more openings 32B for filtering water may be formed in one filtration tank 32 according to the structure, number, and the like of the filtration member 34.

As described above, the filtration tank 32 may be formed with at least one guide hole 32D for connecting to the guide part 40.

In the filtration tank 32, an opening 32C for the filtration member may be formed on at least one of the side and the top surface to detach the filtration member 34.

As shown, in the case where the opening 32C for the filtering member is formed on the upper surface of the filtration tank 32, the sludge 2, the above filtered water, the contaminated water, etc. are not covered with the lid 32C. It may be more advantageous in terms of being able to prevent leakage. In addition, in general, the non-point source treatment structure is installed in the ground as an underground structure, as shown in the opening 32C for the filtering member on the upper surface of the filtration tank 32, for ease of desorption operation of the filtering member 34. It can be said to be more advantageous.

The filtration member 34 may be independently manufactured one by one and assembled in the filtration tank 32. However, as shown in the drawing, when a plurality of filtration members 34 are installed in one filtration tank 32, a plurality of filtration members (at a time) In order to facilitate maintenance and repair by the desorption operation of 34), the plurality of filtration members 34 installed in one filtration tank 32 may be manufactured to be integrated.

The filtration member 34 has a net structure so that the sludge 2 can be hung and water can pass therethrough. In this case, the filter member 34 may have any shape, but it may be more preferable to take a basket shape as follows. That is, the basket-shaped filtration member 34 may have a space in which the sludge 2 may be collected, and even if the filtered sludge 2 is collected, the filtered water may sufficiently pass through the upper portion of the filtration member 34. have.

On the other hand, the filtering member 34 may be further configured, such as a handle to be installed to be detachable to the filtration tank (32).

The guide part 40 may be configured to guide the contaminated water by non-power, such as free fall, but may be more preferably configured to pump the contaminated water by power for efficiency.

That is, the guide portion 40 includes a guide member 42 connecting the sedimentation space 10A of the storage tank 10 and the filtration unit 30, and a sedimentation space 10A of the storage tank 10 along the guide member 42. ) May include a pump 44 for pumping the contaminated water into the filtration unit 30.

Guide member 42 may be configured in various ways, such as a pipe, a hose, a distribution pipe.

The guide member 42 and the pump 44 may be configured in one or two or more depending on the size of the storage tank 10, the position of the sludge 2 collected by the scraper 20, the structure of the filtration tank 32, and the like. . In addition, two or more guide members 42 may be coupled to one pump 44, or two or more pumps 44 may be coupled to one guide member 42.

The scraper 20 is less efficient in collecting the suspended sludge 2, the amount of sludge 2 is settled at the bottom of the settling space 10A of the storage tank 10, the settling space of the storage tank 10 It may be more preferable to be configured to move while scratching the bottom of the settling space (10A) of the storage tank 10 to collect the sludge (2) precipitated on the bottom of (10A).

The scraper 20 may be configured with one or two or more according to the size of the storage tank 10, the structure, the number, the position of the guide portion 40, and the like, as shown in the drawing, as well as being moved along a straight path. It can be moved along various paths such as curved paths, straight lines and mixed paths of curves. However, simplifying the movement path of the scraper 20 can minimize the movement path of the scraper 20, and can scrape the sludge 2 deposited in the sedimentation space 10A of the storage tank 10 without missing. In addition, in view of minimizing the floating of the sludge 2 by the scraper 20, it may be more preferable to configure the scraper 20 to be moved along a straight path.

Such a scraper 20 is more preferably configured to move along the guide rail 22 installed on the bottom of the settling space 10A of the storage tank 10 to prevent shaking. At this time, the scraper 20 may be driven by various power sources according to the situation, such as hydraulic, pneumatic, mechanical.

On the other hand, in the settling space 10A of the storage tank 10, the sludge 2 is collected by the scraper 20, and the dust collecting chamber 50 connected to the guide portion 40 and the more precise guide member 42 is configured. Can be.

That is, since the sludge 2 is collected in a limited space called the dust collection chamber 50, the pump 44 of the guide portion 40 only needs to pump the sludge 2 in the dust collection chamber 50, so that the sludge 2 is sufficiently sludged even with a small capacity ( 2) can be pumped, the sludge 2 collected in the dust collecting chamber 50 by the guide portion 40 can be quickly guided to the filtration unit 30, the sludge guided by the guide unit 40 Since the density of (2) is considerably high, the filtration process by the filtration unit 30 can be performed quickly and effectively, even if agitation occurs in the dust collection chamber 50 due to the operation of the pump 44 of the guide unit 40. It is possible to obtain an effect that the sludge 2 can be prevented from floating into the settling space 10A of the storage tank 10.

Here, the dust collecting chamber 50 may take various structures. However, the sludge 2 guide by the pump 44 of the guide portion 40 is more effective in the closed space than in the open space. Therefore, it may be more preferable that the dust collecting chamber 50 is formed to have an opening 52 through which the sludge 2 collected by the scraper 20 is introduced and can be covered by the scraper 20.

The dust chamber 50 as described above may be installed anywhere. However, it is preferable to be provided at one edge of the storage tank 10 in terms of simplifying the movement path of the scraper 20 and preventing interference with contaminated water in the storage tank 10.

On the other hand, when the dust collection chamber 50 is installed at the edge of the storage tank 10 as described above, in order to avoid interference between the guide unit 40 and the scraper 20, the upper surface of the dust collecting chamber 50 is connected to the guide unit 40. At least one hole 54 may be formed.

On the other hand, the storage tank 10 is generally constructed as a large structure for the effective treatment of the non-point source, in this case it may be more preferable to be constructed by the precast method rather than on-site casting.

In other words, the precast method is a method in which a factory is manufactured in the form of a panel, a box, or the like beforehand and assembled in the field. Therefore, when the storage tank 10 is constructed by the precast method, each member of the storage tank 10 is manufactured in advance in the factory, so that equal quality control is possible, and the frequency of defects and repairs is significantly lowered. The construction is possible even at night, and because there is no need for a separate curing period, the construction period is short compared to the former on-site casting method has a very good advantage.

In addition, by the construction of the storage tank 10, etc. by the precast method, the size and shape of the storage tank 10, etc. can be adjusted in a fluid manner corresponding to the capacity of the storage tank (10).

As described above, the storage tank 10 constructed by the precast method may have various members in consideration of aspects such as fabrication and transportation, ease of construction, and structural stability.

As a preferable example, the storage tank 10 is assembled up and down so as to form a cavity having both ends opened, and each of the upper and lower members 100 and 110 are installed to be connected to each other along the opening direction (arrow L) of the cavity; The upper and lower members 100 and 110 may include a pair of finishing members 120 covering the opened both ends of the cavity to form the precipitation space 10A, respectively.

The upper and lower members 100 and 110 are assembled to be interlocked with each other by the concave-convex structure as shown, in particular, for easier, more robust and accurate assembly, as shown in FIG. 5 'F' and FIGS. 9 and 10. Can be. That is, the upper and lower members 100 and 110 may be formed of the concave-convex surface such as '凹', '凸', wave, etc., in contact with each other.

Of course, the upper and lower members 100 and 110 may be coupled to each other to be restrained by a fastening member such as an anchor bolt, an adhesive, a tension member, or the like, depending on the situation.

The plurality of upper members 100 may be assembled to be engaged with each other by an uneven structure as shown, in particular for easier, more robust and accurate assembly, respectively, as shown in FIG. 4 'E1' and FIG. . In other words, the plurality of upper members 100 may be formed of the uneven surfaces such as '凸' and waves that are in contact with each other. Of course, in particular, as shown in 'E2' of FIG. 4, 'E3' of FIG. 6 and FIG. 10, the plurality of lower members 110 may also be assembled to each other by an uneven structure.

In addition, the tension member 130 may be fixed to each member of the storage tank 10 in order to increase structural stability by restraining and prestressing each member of the storage tank 10. Here, in the storage tank 10, the tension member fixing groove 10B may be formed for ease of fixing the tension member 130.

Furthermore, the storage tank 10 may further include at least one partition member 140 partitioning the precipitation space 10A.

That is, as shown, a plurality of scrapers 20, a dust collecting chamber 50, a guide portion 40, etc. are installed in accordance with the size, structure, etc. of the storage tank 10, the interference caused by the driving of the plurality of scrapers 20 As a result, more agitation is generated in the settling space 10A of the storage tank 10 and the sludge 2 is more susceptible to flotation, so that the partition member 140 collects the sludge 2 effectively by the scraper 20. It may be more preferable that the precipitation space 10A is partitioned.

However, even when only one inlet portion or the outlet portion of the storage tank 10 is formed, the partition member 140 may include at least one opening 142 so that the contaminated water may be communicated in order to facilitate access of the contaminated water. It is preferable to be formed to have.

Such a partition member 140 may be manufactured integrally with the upper member 100 and the lower member 110 as shown. That is, the partition wall member 140 is formed integrally with the upper member 100 and the upper partition wall portion 140A, and the lower member 110 is made integrally with the upper partition wall portion 140A to form the partition member 140. It may be configured to include a lower partition wall portion 140B.

Of course, depending on the situation, the partition member 140 is manufactured separately from the upper member 100 and the lower member 110, the upper member 100 and the lower member (by the fastening member such as anchor bolt, adhesive such as epoxy, etc.) 110 may be assembled.

In addition, the storage tank 10 is a power pack member (powerpack member) in which the driving unit 24 may be built in at least one of the upper member 100 for the stable installation of the driving unit for driving the scraper 20 ( 150 may be formed. The power pack member 150 may be manufactured integrally with the upper member 100 or separately manufactured and assembled.

Meanwhile, at least one guide hole 104 is formed in at least one of the upper members 100 so that the guide part 40 can pass therethrough, and the filtered water can flow into the settling space 10A of the storage tank 10. At least one hole 106 for filtration is formed.

In addition, as shown in FIG. 11 or less, in the present invention, at least one stirring hole 20A is formed in at least one of the scraper 20 and the dust collecting chamber 50, and the guide portion 40 When the sludge 2 in the dust collecting chamber 50 is pushed by the opening and closing part 60 for opening the stirring hole 20A may be further included.

That is, when the sludge 2 in the dust collecting chamber 50 is pressurized by the guide part 40 in the state where the opening 52 of the dust collecting chamber 50 is covered by the scraper 20, the stirring hole ( When 20A) is opened, a flow toward the inside of the dust collecting chamber 50 may be generated through the stirring hole 20A by the pressure feeding force by the guide part 40.

Therefore, the flow causes agitation inside the dust collection chamber 50, and the sludge 2 in every corner of the dust collection chamber 50 is also placed under the influence of the pressure force of the guide portion 40 by this agitation. .

As a result, a dead zone in which the sludge 2 is not easily conveyed by the pressure of the guide part 40 in the dust collecting chamber 50 may be prevented, and the guide part 40 may be prevented. The sludge pumping efficiency can be maximized.

Here, the stirring hole 20A may be formed of both the scraper 20 and the dust collecting chamber 0, but is formed by the scraper 20 rather than the dust collecting chamber 50, and the structural simplification and the interference with the guide portion 40. It may be more preferable in terms of avoidance.

In this case, the number, size, shape, etc. of the stirring hole 20A may be determined according to the structure of the scraper 20, the dust collecting chamber 50, and the guide part 40.

Opening and closing part 60 may be implemented in various ways, such as a power method, a manual operation method by the power of the motor, etc., particularly shown by the non-powered interlocking method, that is, the stirring force 20A by the pressure of the guide unit 40 It is more preferable to be configured to open

That is, the opening and closing part 60 rotates toward the dust collecting chamber 50 by the cover panel 62 formed to cover the stirring hole 20A, and the cover panel 62 by the pressure force of the guide part 40. The hinge shaft 64 and the cover panel 62 are installed in the scraper 20 so that the stirring hole 20A can be opened so that the cover panel 62 can be rotatably installed in the stirring hole 20A. It may be configured to include a stopper 66 to limit the rotation to the opposite side of the dust chamber (50).

Accordingly, when the scraper 20 scrapes the sludge 2 toward the dust collecting chamber 50 as shown in FIG. 11, the sludge 2 is external to the cover panel 62 by the sludge 2 on the opposite side of the dust collecting chamber 50. The force acts, and at this time, the opening panel 62 is restrained by the stopper 66, so that the stirring hole 20A is closed by the opening panel 62, that is, the stirring hole 20A is closed. maintain.

On the other hand, in the state where the scraper 20 covers the opening 52 of the dust collecting chamber 50 and the pressure force of the guide portion 40 is formed inside the dust collecting chamber 50, the pressure of FIG. As shown by the dotted line, the cover panel 62 is rotated from the stirring hole 20A to the dust collection chamber 50 side by the pressing force of the guide part 40 about the hinge axis 64, thereby causing the stirring hole ( 20A) can be opened.

Of course, when the pressure force of the guide portion 40 is released, as shown by the solid line in FIG. 12, the cover panel 62 is returned, and the stirring hole 20A is closed again by the cover panel 62. .

At this time, the open panel 62 is rotated by the hinge shaft 64, such as the middle portion, the lower portion, the left and right sides, although not shown, the upper end is bound to the hinge shaft 64, as shown, the stirring hole ( 20A) can be engaged with the hinge shaft 64 wherever it can be opened and closed.

On the other hand, although the opening and closing portion 60 is not shown, when the pressing force of the guide portion 40 is not formed, the cover panel 62 may support the cover panel 62 by the elastic force in the direction in which the aperture hole 62A closes the stirring hole 20A. It may further include an elastic member such as a spring. That is, when the pressure force of the guide portion 40 is not formed, the closed state of the stirring hole 20A may be maintained more firmly by the elastic member, and the elastic member may be released when the pressure force of the guide portion 40 is released. By this, the cover panel 62 can be returned more quickly.

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
