Abstract

The present invention relates to a selective treatment device for rainfall runoff, opening and closing the first and second outflow holes perforated in the downstream wall on both ends of the lever rotatably installed on the downstream wall of the water collection tank and having a specific gravity smaller than water. The first and second opening and closing plates are provided, and the second opening and closing plate is heavier than the first opening and closing plate, so that the buoyancy received from the water is increased, so that the rainfall outflow water level in the collection tank or the rainfall runoff level in the collection tank is not set. If it is below, the second opening and closing plate descends due to the weight difference with the first opening and closing plate to close the second outflow hole, the first opening and closing plate is raised to open the first outflow hole, and the rainfall runoff is transferred to the non-point pollutant treatment facility. When the rainfall outflow water level in the sump is above the set value, the second open / close board floats due to the buoyancy difference from the first open / close board and opens the second outlet hole. As the first opening and closing plate descends, the first outflow hole is closed, and the rainfall runoff that flows into the sump is bypassed to the rainwater pipe through the second outflow hole and is not transferred to the nonpoint pollutant treatment facility through the first outflow hole. It is possible to reduce the load on pollutant treatment facilities and to miniaturize nonpoint pollutant treatment facilities.

Description

Selective treatment apparatus for storm water runoff

The present invention relates to an apparatus for selective treatment of rainfall effluent, and more specifically, initial rainfall effluent containing a large amount of nonpoint pollutants and rainfall effluent after a predetermined time has passed since the initial rainfall containing a small amount of nonpoint pollutants below a reference value. The present invention relates to an apparatus for selective treatment of rainfall effluent, which can be transported through different routes to reduce the load on non-point pollutant treatment facilities.

In general, rainfall runoff contains nonpoint pollutants and is then discharged through rain pipes after treatment through a nonpoint pollutant treatment facility.

The initial rainfall runoff contains a large amount of nonpoint pollutants, and the rainfall runoff after a certain time has elapsed since the initial rainfall (hereinafter referred to as 'rainfall runoff since the initial stage') includes nonpoint pollutants below the standard value.

In this way, the initial rainfall runoff containing a large amount of nonpoint pollutants and the initial rainfall runoff containing subpoint pollutants below the standard value are all treated through a nonpoint pollutant treatment facility and discharged through rainwater pipelines. A large load is placed on the treatment facility, and a problem arises in that the non-point pollutant treatment facility needs to be large in order to cope with such a load.

Therefore, in recent years, rainfall runoff has been treated by non-point pollutant treatment facilities and discharged through rainwater pipelines, and since rainwater runoff has been discharged directly through rainwater pipelines without going through non-point pollutant treatment facilities. Research on non-point pollutant treatment facilities capable of selective treatment is being actively conducted.

Conventional non-point pollutant treatment facilities capable of selective treatment of rainfall runoff have a bypass wall installed at the inflow portion of the rainfall runoff at the non-point pollutant treatment facility, and when the inflow level is lower than that of the bypass wall. The amount of rainfall outflow water flowing into the inlet is treated and discharged. When the water level of the inflow part is higher than the bypass wall for the inflow, the rainfall outflow introduced into the inlet is bypassed and discharged through the bypass wall.

However, in the conventional non-point pollutant treatment facility capable of selective treatment of rainfall runoff, when the inflow level is higher than the bypass wall for bypass, some rainfall runoff that flows over the overflow wall is discharged through the bypass path, Some rainfall runoff is treated and discharged, which does not alleviate the load on nonpoint pollutant treatment facilities.

Accordingly, an object of the present invention is to treat the initial rainfall runoff in a non-point pollutant treatment facility by treating the rainfall runoff to either the non-point pollutant treatment facility or rainwater pipe according to the incoming rainfall runoff level, and the rainfall after the initial runoff is It is possible to reduce the load on non-point pollutant treatment facilities by allowing them to be discharged immediately without going through the non-point pollutant treatment facility, and to provide a selective treatment device of rainfall effluent water that can reduce the size of the non-point pollutant treatment facility.

It provides a selective treatment device of rainfall runoff.

The first and second opening and closing plates are fixedly installed at both ends of the lever.

Guide guide holes are formed at both ends of the lever, and the first and second opening and closing plates guide guides guided to the guide holes are provided to protrude, and the downstream wall guides the first and second opening and closing plates to move up and down linearly. A guide rail is provided.

Selective treatment apparatus for rainfall runoff according to the first embodiment of the present invention, as shown in Figs. 1 and 2, the water collecting tank (10) comprising an upstream wall (11) and a downstream wall (12); An inlet pipe 20 connected to an upstream wall 11 of the sump tank 10; First and second outlet holes 31 and 32 drilled left and right in the downstream wall 12; A lever (40) whose middle portion is rotatably supported between the outlet holes (31, 32) of the downstream wall (12); It is provided on both ends of the lever 40 and comprises opening and closing plates (50, 60) for opening and closing the first and second outlet holes (31, 32).

The sump 10 is a place where rainfall runoff is collected, and its size may be determined according to rainfall characteristics for each region.

The inlet pipe 20 may be connected to the lower or upper portion of the sump (10) according to the installation site characteristics of the selective treatment device of rainfall outflow water according to the present invention.

The first and second outlet holes 31 and 32 may be directly formed in the downstream wall 12 of the water collecting tank 10, but may be formed by a pipe embedded in the downstream wall 12. .

The lever 40 is rotatably supported by a central shaft 41 whose intermediate portion is fixed to the upstream wall 11. The central shaft 41 may be directly fixed to the upstream wall 11, but it is preferable to fix the bracket 42 to which the central axis 41 is fixed to the upstream wall 11 as shown in the example.

The lever 40 and the first and second opening and closing plates 50 and 60 are integrally formed. 43 is a shaft hole which is drilled in the middle portion of the lever 40 so that the central shaft 41 is fitted.

The first and second opening and closing plates 50 and 60 may be configured such that the second opening and closing plate 60 is the first opening and closing plate when the rainfall outflow water does not flow into the sump tank 10 or when the rainfall outflow water level in the sump tank 10 is lower than or equal to a predetermined value. Dropping by the difference in weight with (50) to close the second outflow hole 32, the first opening and closing plate 50 is raised to open the first outflow hole 31 to the rain runoff water to the non-point pollutant treatment facility In addition to being transported

When the rainfall outflow water level in the sump 10 is greater than or equal to the set value, the second opening and closing plate 60 floats due to the buoyancy difference with the first opening and closing plate 50 to open the second outflow hole 32 and open the first opening and closing plate ( 60 is lowered to close the first outflow hole 31, and the rainfall outflow water flowing into the sump tank 10 is bypassed through the second outflow hole 32 to the rain pipe and the boiling point through the first outflow hole 31. The weight and buoyancy that can be received in water are configured differently so that they are not transported to the pollutant treatment plant.

That is, the first and second opening and closing plates 50 and 60 are formed of a material having a specific gravity smaller than that of water, and the weight of the second opening and closing plate 60 is higher than that of the first opening and closing plate 50. Configure the buoyancy to be greater.

The first and second opening and closing plates 50 and 60 may be made of the same material or different materials, and as a result, the second opening and closing plate 60 may be formed of the first opening and closing plate 50 in terms of weight and buoyancy. Configure it to be larger.

Specifically, the volume of the second opening and closing plate 60 is larger than the first opening and closing plate 50 so that the second opening and closing plate 60 is larger than the first opening and closing plate 50 in terms of its weight and buoyancy. You can do that,

As illustrated, the second opening and closing plate 60 includes the second opening and closing plate 60 as the opening and closing plate portion 61 and the weight / buoyancy increasing member 62, and the first opening and closing plate 50 is the opening and closing plate portion. The second opening and closing plate 50 may be configured to have the same size as that of 61, so that the second opening and closing plate 50 is larger than the first opening and closing plate 50 in terms of weight and buoyancy by the weight / buoyancy increasing member 62.

The first outlet 31 is connected to the reaction tank 80 constituting the non-point pollutant treatment facility, the second outlet 32 is connected to the bypass channel 90. The reactor 80 is filled with the filter medium 81, and the rainfall runoff water filtered by the filter medium 81 is configured to discharge the overflow wall 82 by overflow.

Hereinafter, the operation of the selective treatment device of rainfall runoff according to the present embodiment.

The first and second opening and closing plates 50 and 60 are fixed to both ends of the lever 40 whose middle part is rotatably supported by the central shaft 41 fixed to the downstream wall 12 of the water collecting tank 10. Since it is provided, when one of the opening and closing plates 50 or 60 is raised, the other opening and closing plate 60 or 50 is lowered.

When the rainfall outflow water does not flow into the sump (10) or the rainfall outflow water level in the sump (10) is below the set value, as shown in (a) of FIG. 2, the second opening and closing heavy than the first opening and closing plate 50 The plate 60 is lowered to close the second outlet hole 32, and the first opening and closing plate 50 provided at the end of the lever 40 on the side opposite to the second opening and closing plate 60 is raised to 1 The outflow hole 31 is opened so that the rainfall runoff flows into the sump tank 10 is introduced into the non-point pollutant treatment facility, that is, the reaction tank 80 through the first opening and closing plate 50 and treated by the filter medium 81. After being discharged by overflowing the overflow wall 82, the bypass through the second outflow hole 32 does not occur.

Therefore, in this case, the rainfall runoff flowing into the water collecting tank 10 is transferred to the non-point pollutant treatment facility through the first outflow hole 31, and then discharged.

On the other hand, when the rainfall outflow water level in the sump (10) is above the set value, the second opening and closing plate 60, which is subjected to greater buoyancy than the first opening and closing plate 50 is raised to open the second outflow hole (32) On the opposite side of the second opening and closing plate 60, the first opening and closing plate 50 provided at the end of the lever 40 is lowered to close the first outflow hole 31 so as to flow into the water collecting tank 10. Rainwater runoff is bypassed to the bypass channel 90 through the second outlet hole 32 and is not transferred to the non-point pollutant treatment facility through the first outlet hole 31.

Therefore, in this case, the rainfall runoff flowing into the collection tank 10 is not treated in the non-point pollutant treatment facility, and is discharged to the rainwater pipe through the second outlet hole 32 and the bypass channel 90.

As a result, when the water level in the sump (10) is below the set value, the rainfall runoff is transferred to the non-point pollutant treatment facility and discharged after the non-point pollutant is processed, and when the water level in the sump (10) is above the set value, the rainfall outflow is non-point pollution Since it is not transferred to the material treatment facility and discharged as it is through the bypass channel 90, the load of the non-point pollutant treatment facility can be minimized, and the non-point pollutant treatment facility can be miniaturized.

It further comprises a guide rail (71, 72) for guiding the first and second opening and closing plate (50, 60) to move up and down linearly.

In the selective treatment apparatus of rainfall runoff according to the present embodiment, when the first and second opening and closing plates 50 and 60 are lifted and operated, the central axis 41 is positioned according to the positions of the first and second opening and closing plates 50 and 60. ) And the distance between the guide pins 51 and 63. The guide pins 51 and 63 are guide holes 44 and 45 for guiding the guide pins 51 and 63 at both ends of the lever 40, respectively. The lowering operation of the boards 50 and 60 will not cause any trouble.

In addition, the first and second opening and closing plates 50 and 60 are connected to the lever 40 by the guide holes 44 and 45 and the guide pins 51 and 63 to open and close the first and second openings. Although the plates 50 and 60 are rotatable, the guide rails 71 and 72 fixed to the downstream wall 12 are linearly moved up and down by the first and second opening and closing plates 50 and 60. The first and second opening and closing plates 50 and 60 are operated precisely between the opening and closing positions because they are guided.
