The present invention relates to a sedimentation basin in a water treatment plant, such as a rectangular secondary sedimentation basin in a sewage treatment plant, and more particularly, because the inflow water is prevented from flowing from side to side in the sedimentation basin, while preventing a decrease in sedimentation rate due to the inflow flow, By maintaining the inflow of the sedimentation basin by a constant to prevent the sludge from being pushed to the end of the sedimentation basin relates to a water treatment plant sedimentation basin to prevent sludge contamination or injury.

In the physical or biochemical treatment of water treatment facilities, such as water treatment plants and sewage treatment plants, influent (treated water) is stored for a period of time or flowed at a low flow rate so that solid contaminants, such as sludge (sludge) Sedimentation process, also called sedimentation pond, is called settling pond.

On the other hand, such sedimentation basin is usually divided into primary sedimentation basin and secondary sedimentation basin according to the target solid contaminants, the primary sedimentation basin plays a role of pretreatment for primary treatment and biological treatment, secondary sedimentation basin for biological treatment The main purpose is to separate the sludge generated by the treatment and the treated water.

Therefore, in the secondary sedimentation basin, such as sewage treatment plant, sludge transported from the bioreactor is precipitated, and such precipitated sludge is usually removed from the sedimentation basin by transferring it to the sludge hopper using a sludge collector which scrapes the bottom of the sedimentation basin. .

On the other hand, secondary sedimentation sites of known conventional sewage treatment plants differ depending on the construction conditions, but the depth reaches approximately 3-4 m, the length (long side) is at least 50-70 m, and in the case of a rectangle, the length is 3- It is a large structure about five times as large as a concrete structure. Therefore, such sewage treatment plant sedimentation basin is called a rectangular gravity sedimentation basin.

However, in the secondary sedimentation basin, a stone jaw supporting the movement of the sludge collector across the center of the structure (see '120' in FIGS. 1 and 2) is erected, and the overflow port ('130' in FIG. Pillars (see '140' in Figures 1 and 3) are erected, and at the ends of the sedimentation basin, there are overhangs (see '130' in Figures 1 and 2) respectively.

By the way, the sedimentation basin to precipitate the sludge on the bottom through the gravity sedimentation separation occurs depending on the depth, for example, the water temperature and the water temperature in the deep portion of the sedimentation basin is different.

That is, since water on the surface of the water receives sunlight, the temperature of the water is higher than that of the inner deep portion, and this temperature difference affects the density flow in the sedimentation basin, and this density flow causes the flow of water in the sedimentation basin into turbulent state. Therefore, it is known to prevent precipitation in the sedimentation basin.

In particular, in the case of the secondary sedimentation basin of the known sewage treatment plant, the inflow water flows freely from side to side based on the sill, in the center of the rectangular structure, only the posts are provided in the longitudinal direction.

Therefore, sedimentation of the sludge is prevented by the flow of sludge in the left and right flow of the inflow water in the sedimentation basin of the water treatment plant, in particular, the sewage treatment plant.

Accordingly, the applicant of the present invention installs a partition wall in the middle of the sedimentation basin of the sewage treatment plant to block the inflow of water from the sedimentation basin to increase the sedimentation efficiency, as well as to reduce the width of the sedimentation basin in half, and the width-to-width ratio in half. By increasing the ratio of, the sedimentation basin was proposed to increase the sedimentation efficiency while inducing the influent sedimentation path uniformly.

On the other hand, the applicant of the present invention to increase the sedimentation efficiency by increasing the sedimentation efficiency by uniformly flowing the influent water flowing into the sedimentation basin using the rectifying wall even if the quantity of inflow water flowing into the sedimentation basin is not constant for each time period, while the amount of water rapidly increases As a result, an improved settling basin is proposed to install a rectifying wall to prevent the sludge from being pushed.

The present invention has been proposed in order to improve the conventional problems as described above, and its object is that the inflow of the inflow water from the sedimentation basin is prevented from falling, while preventing the decrease in the settling rate due to the inflow of the inflow water. It provides a water treatment plant sedimentation basin that keeps the sediment inflow constant so as to prevent sludge from being pushed to the end of the sedimentation basin.

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

1 to 3 show the overall configuration of the water treatment plant sedimentation basin 100 according to the present invention, in particular, the rectangular secondary sedimentation basin in the sewage treatment plant in an overall configuration diagram, a front view and a plan view.

Therefore, hereinafter, the secondary sedimentation basin of the sewage treatment plant will be described. The configuration related to the sedimentation basin will be described with reference numeral 100 units, and the partition and rectifying walls, which are the characteristic constitutions of the present invention, will be described with reference numerals of 10 units.

For example, as shown in Figures 1 to 3, with reference to the secondary sedimentation battery 100 of the sewage treatment plant of the present invention, the rectangular concrete structure 110, that is, the floor and the associated with the primary sedimentation basin 100 ' A hopper comprising a structure 110 forming a side wall, and the sediment sludge treated by the sludge collector (not shown) moving along the bottom of the structure at the inflow side of the structure 110 ('110a' of FIG. 1). ) Is provided.

In addition, as shown in Figure 2, in the center of the structure 110 of the secondary sedimentation basin 100 of the sewage treatment plant of the present invention, the bottom 120 to guide the movement of the sludge collector driven to both sides of the sedimentation basin is integrally integrated It is provided.

In addition, the pillars 140 are arranged at regular intervals such that the overflow port 130 is long along the center of the sedimentation basin structure along the ridge 120 of the secondary sedimentation basin 100 of the sewage treatment plant.

Secondary sedimentation basin 100 of the sewage treatment plant of the present invention having such a structure, the partition wall 10 provided to prevent the flow of inflow in the longitudinal direction of the sedimentation basin structure 110, and the inlet water to the inlet of the sedimentation basin structure At the same time characterized in that it comprises a rectifying wall (30) provided to allow a constant inlet.

Therefore, in the secondary sedimentation basin 100 of the sewage treatment plant of the present invention, since the partition 10 is constructed vertically across the center of the sedimentation basin structure, since the length of the width is generally divided into two, the width ratio is long, that is, the width Since the ratio of and length is enlarged, the flow of the influent flows very stably, in particular because the influent does not flow from side to side based on the stone wall 120, the precipitation efficiency is very high.

Meanwhile, the structure of the partition wall 10 of the present invention will be described in more detail as follows.

First, an example of the partition wall 10 according to the present invention is illustrated in FIGS. 4 to 6, and another example of the partition wall 10 according to the present invention is illustrated in FIG. 7.

That is, as shown in Figure 4, the partition wall 10 of the present invention, the panel member constructed vertically in the longitudinal direction of the structure to block the left and right flow of the inflow across the center of the sedimentation basin structure 110 and , The panel fixing means 14 for constructing the structure of the panel member is characterized in that.

5 and 7, the panel member in the partition 10 of the present invention may be provided as the hollow panel 12a of FIG. 5 or the uneven panel 12b of FIG. 7. Alternatively, it is also possible to use panels of integral plates that are not shown in separate figures.

On the other hand, the hollow panel 12a, as shown in FIG. 5, can be used both the panel having a hollow portion integrally formed with the hollow portion during molding or forming a hollow portion by joining the uneven panel and the plate.

Alternatively, it is preferable to use a shock resistant hollow panel 12a that withstands water pressure, but as shown in FIG. 7, an uneven panel 12b having increased structural strength or an integral plate having an increased thickness as a single piece may be used.

Next, the panel fixing means 14 of the partition wall 10 of the present invention, as shown in Figures 5 to 7, by connecting and fixing the unit panels (12a) (12b) to be assembled, vertically and horizontally A panel fixture 16 constituting one partition wall, and a structure fixture 18 for fixing the panel members to the structure.

In this case, as shown in FIGS. 5 to 7, it is also preferable to further construct a panel upper fixing body 20 on the panel member upper end of the partition wall 10.

In addition, the barrier panels 12a and 12b are corrosion resistant and synthetic resin products, but have increased strength of polyethylene (PE), sheet molding compound (SMC), glass fiber (glass) reinforced plastic (FRP, GRP), and polycarbonate. (Poly-Cabonate) or Polyurethane (Poly-Urethan) can be produced.

In addition, the panel fixture 16 of the panel fixing means 14 of the partition 10, the panel fixture 18 and the upper fixture 20 of the panel may be fastened to the panel member and the bolt B1, or 110) That is, it may be used as the 'L' or 'C' shaped steel, etc., which is anchored to the bottom of the structure, the stone wall 120 or the wall outlet 140 (B2).

For example, as shown in FIG. 5 and FIG. 6, the structure fixing body 18 of the panel to be installed on the stone jaw 120 is constructed by abutting the 'L' shaped steel as an anchor B2 and the panel 12a in the space therebetween. 12b) is inserted into the bolt, and the pillar 140 may be anchored (B2) by the construction of the 'C' shaped steel 18 to be fastened as a bolt (B1).

5 and 7, the upper fixture 20 may also be firmly constructed by covering the top of the panel using 'C' shaped steel.

At this time, as shown in Figures 5 to 7, each of the fixtures 16, 18, 20 is any one of corrosion-resistant glass fiber reinforced resin, stainless steel, epoxy coated structural steel, aluminum It is desirable to fabricate and prevent corrosion.

On the other hand, as shown in Figure 1, it is preferable that the partition wall 10 of the present invention is formed at least higher than the overflow port 130 in a portion where the overflow port is not disposed in the sedimentation basin.

For example, if the bulkhead is lower in the part where there is no overflow opening, the inflow of sewage may occur.

Next, FIGS. 8 and 9 illustrate the rectifying wall 30 provided in the secondary sedimentation basin 100 of the sewage treatment plant according to the present invention.

For example, the rectifying wall 30 of the secondary sedimentation basin of the sewage treatment plant of the present invention is constructed such that the panels 34 provided with holes 32 form one or more rectification walls across the sedimentation basin width direction. The hole 32 has a structure in which a rectifying hole forming tool 38 for forming a separate rectifying hole 36 is fastened.

In this case, as shown in FIG. 9, in the rectifying wall 30 of the present invention, the rectifying hole forming hole 38 connects the fastening jaw portion 38a and the rectifying hole fastened to the wall surface of the panel hole 32. The rectifying hole forming portion 38b inserted into the panel hole and extending to be formed is integrally formed, and the rectifying hole forming portion is provided in a conical shape in which the inner diameter decreases (D1-> D2) from the water inlet side to the outlet side.

Therefore, as shown in FIGS. 1 and 9, the rectifying wall 30 of the present invention engages a separate rectifying hole forming hole 38 in the panel hole, and the inflow water flows out to the sedimentation basin side through the rectifying hole 36 therein. However, since the rectifying hole 36 has a shape in which the inner diameter is reduced, it provides the following advantages.

For example, as shown in Figure 9, the secondary sedimentation basin 100 of the sewage treatment plant having a rectifying wall 30 of the present invention, since the internal diameter of the rectifying holes 36 is reduced at the exit side, the inner diameter at the rectifying hole entrance side Since (D1) flows out through the reduced inner diameter (D2) in a wide state, vortices are severely generated in the outflow portion, and such vortices increase the biocoagulation rate of sludges such as fine flocs (FLOC), so that precipitation is smoother. To be implemented.

In addition, a large amount of nitrate nitrogen generated in the biological reactor in the previous stage is introduced into the sedimentation basin 100 during sewage treatment. The nitrate nitrogen introduced into the sedimentation basin is deoxygenation when oxygen-free and organic substances are supplied. There is a risk of being discharged into the atmosphere as nitrogen gas throughout.

Therefore, when there is no rectifying wall as in the present invention, the time varies, but when the inflow increases instantaneously, the sediment is pushed toward the end of the sedimentation basin by the amount of the inflow, and the pushed sediment, that is, the sludge collector (not shown) Since it takes a long time to move to the hopper 110a, the organic matter may be discharged by the self-decomposition phenomenon that the sludge itself decomposes, and the anoxic conditions of the sedimentation basin cause the denitrification of the nitrate nitrogen introduced. To cause denitrification in the secondary settling basin.

At this time, the generated nitrogen gas is caused to rise with the sludge, in which case the injured sludge is leaked to the overflow port 130 as it is.

However, in the case of the sedimentation basin 100 of the present invention, since the rectifying wall 30 is provided in the sedimentation basin structure, even if the amount of inflow is rapidly increased, the inflow into the sedimentation basin is constantly adjusted, so that the sludge is pushed toward the end of the sedimentation basin. Loss does not occur.

Moreover, since the surface load ratio which suppresses the rise of the sludge settled in the sedimentation basin is increased, sludge sedimentation efficiency is raised.

As described above, the rectifying wall 30 of the present invention is disposed at least one at the inlet side of the sedimentation basin, and is disposed not to interfere in view of the sludge collector's movement path (specifically, a chain movement path for collector operation). to be.

Meanwhile, as shown in FIGS. 8 and 9, the rectifying wall 30 provided in the sedimentation basin 100 of the sewage treatment plant of the present invention is also the same as the partition wall 10 described above. The unit panels having the silver holes uniformly arranged may be constructed as one rectifying wall with the panel fixture 40 vertically and horizontally.

In addition, the panels may be constructed to cross the structure width direction through the structure fixing body 42.

In this case, as shown in FIG. 9, the panel upper fixture 44 may be further constructed at the upper end of the panel 34 of the rectifying wall 30.

The panel 34 of the rectifying wall has a plate shape in which holes 32 are formed, but is corrosion resistant and is a resin product, but polyethylene (PE), sheet molding compound (SMC), and glass fiber (glass) have increased strength. ) It can be made of reinforced plastic (FRP, GRP), polycarbonate (Poly-Cabonate), polyurethane (Poly-Urethan).

8 and 9, the panel fixture 40 of the rectifying wall 30, the structure fixture 42 and the upper fixture 44 of the panel are the panel member and the bolt B1 like the partition wall. To be fastened or to be constructed with an 'L' or 'C' shaped steel, which is anchored to the structure 110, ie, the bottom of the structure 120 and the fixing body (or the overflow hole column) of the partition 10, or the like. Can be.

For example, as shown in FIGS. 8 and 9, the structure fixture 42 of the panel constructed on the bottom of the structure 110 is constructed by facing the 'L' shaped steel as the anchor B2 and installing a panel ( It is also possible to fasten the bolts by inserting 34 and anchoring the 'C' shaped steel (not shown) to the fixtures of the pillars 140 or the partition walls 10 between the pillars.

8 and 9, the upper fixture 44 may also be firmly constructed by covering the top of the panel using 'C' shaped steel.

At this time, each of the rectifying wall fixtures 40, 42, 44 of the present invention is made of corrosion resistant glass fiber reinforced resin, stainless steel, epoxy coated structural steel, aluminum to prevent any corrosion It would be desirable.

Next, FIG. 10 illustrates a baffle 50 additionally provided in the water treatment plant sedimentation basin, that is, the sewage treatment plant secondary sedimentation basin 100.

For example, as illustrated in FIGS. 10A and 10B, as described above, the density flow is generated according to the temperature difference of the water in the sedimentation basin. In particular, the partition wall of the present invention installed across the wall or in the middle of the sedimentation basin structure 110 ( It is known that flow flotation of sludge along 10) occurs more easily.

Therefore, in the sedimentation basin structure 110 and the baffle 50 provided on the partition 10 of the present invention, as shown in FIG. 10A, the sludge S rides on the structure wall or the partition 10 due to the density flow. Injury (the path of S ') blocks inflow into the overflow port 130 in advance.

As a result, the baffle of the present invention is disposed in the path that is easy to rise of the sludge, serves to block the rise of the sludge (S) and to change the sludge flow path (S ') to the bottom of the settling basin.

The baffle 50 of the present invention as shown in FIG. 10b shows the construction structure in detail.

That is, the baffle 50 of the present invention has a plurality of triangular frames 52 provided with a plurality of spaced along the settling basin structure 110 and the partition wall 10 and the slanted sludge guide surface 52a of the frame 52. It consists of a baffle plate (54) elongated and attached along.

At this time, the frame 52 is fixed to the structure as an anchor bolt (B2) made of a material such as 'C' section steel, or the panel fixture 16 of the partition 10 and the panel of the structure fixture 18 of the panel It is preferably a triangular shape that is connected to the fixing means 14 or the upper fixing body 20, the lower portion is flat and one side is inclined sludge guide surface 52a.

In addition, the baffle plate 54 may be a corrosion-resistant rubber plate that extends long in the frame and is installed along the bulkhead of the structure part (both sides of the string) and the central partition.

Accordingly, as shown in FIGS. 10A and 10B, the floating path S ′ of the sludge S that easily floats along the sedimentation density oil along the wall or the partition 10 of the structure 110 is a baffle plate of the baffle 50. In line 54, the sludge is smoothly settled at the center of the settling basin.

At this time, although schematically shown in Figure 10b, the baffle 50 of the side wall of the structure is formed in the elongated hole 130, the support portion (concrete structure) is a long hole in the treatment water passes at a predetermined interval is formed long in this portion Can be.

As described above, according to the sedimentation basin of the water treatment plant of the present invention, the inflow of the inflow water is prevented from flowing left and right in the sedimentation basin to prevent precipitation decrease due to the inflow of the inflow.

In addition, even if the inflow of the influent water in the inlet environment, for example, the inflow water amount by time, the inflow of the inflow water to the settling basin is constant to solve the problem of the sludge being pushed to the end of the sedimentation basin.

As a result, the water treatment plant sedimentation basin of the present invention, in particular, the longitudinal secondary sedimentation basin of the sewage treatment plant, provides an effect of greatly improving the sedimentation efficiency.
