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

As shown in FIG. 1, a wastewater treatment facility according to the present invention basically includes a wastewater treatment unit 1A in which wastewater generated by construction works such as rivers, lakes, canals, and the like is purified. Can be configured.

The wastewater treatment unit 1A can take various structures depending on the wastewater purification treatment method, the wastewater treatment capacity, and the like.

For example, polluted water generated in construction, civil engineering works, etc., is usually turbid by soil or organic material rather than contaminated by chemicals.

Therefore, in this case, the wastewater treatment unit 1A may have a more preferable method of precipitating and treating sludge (S) such as soil and organic substances from the wastewater by precipitation.

Furthermore, it may be more preferable that the sedimentation wastewater treatment unit 1A precipitates sludge S from the wastewater in multiple stages. Preferably, as shown in Figure 1, the sewage water treatment unit (1A) of the sedimentation method is the initial sedimentation step (A) for sedimentation and sedimentation by activating the sludge (S) by the influent water flow, and the water flow In the stabilization state of the sludge (S) in the rectification step (B), and the sewage water purified by the sedimentation method, that is, the discharged step (C) in which the treated water is discharged in an overflow (flow) method It may be provided to treat the effluent. Here, the discharge step (C) may be further provided with a filter medium (60) for adsorbing and filtering the sludge (S) from the treated water is overflow discharged.

On the other hand, the wastewater treatment facility according to the present invention may further include a mechanical equipment (1B) so that the wastewater can be purified more easily and efficiently by the above-mentioned wastewater treatment unit (1A).

The mechanical equipment 1B may be configured in various ways according to the method for purifying wastewater and the wastewater treatment capacity.

One of the mechanical equipments 1B includes a pump 4 for pumping the wastewater by power so that the wastewater can be introduced into the wastewater treatment unit 1A quickly and easily from the river 2, the lake, the canal, or the like. Can be configured.

In addition, as the mechanical equipment 1B, a coagulant supply unit 6 may be configured to supply a coagulant for agglomeration of the sludge S so that the coagulation of the sludge S may be more activated in the initial precipitation step (A). have.

The coagulant supply unit 6 is connected to the effluent treatment unit 1A to guide the inflow of the effluent so that the coagulant is rapidly mixed with the effluent so that the coagulation of the sludge can be performed quickly and actively ( It may be more preferable to connect with 10).

In this case, the mixed water and the coagulant mixed with each other, such as inline mixer (inline mixer) for mixing the water and the flocculant before entering the waste water treatment unit (1A) so that the mixed well and the coagulant ( Can pass 7).

Also, as the mechanical equipment 1B, a by-pass 8 for returning the polluted water pumped by the pump 4 back to a river, a lake, a canal, or the like, may be configured to control the amount of the influent water. Can be.

In addition to the dirty water purification treatment, the mechanical equipment 1B may be configured in various ways.

Hereinafter, the wastewater treatment unit described above will be described in more detail with reference to FIG. 2.

The wastewater treatment unit may basically include a treatment tank 20 having a treatment space 23 in which sludge S in the polluted water is deposited while the wastewater remains.

In particular, the treatment tank 20 includes a side wall member 22 that forms a treatment space 23 for treating wastewater; The bottom surface of the side wall member 22 is covered, and the plane of the processing space 23 formed by the side wall member 22 by a flexible material so that at least a portion thereof can be easily inclined by the lower fill 100 or the pedestal ( 23 ') may be configured to include a; bottom member 24 is formed in a larger area than.

That is, when the bottom member 24 is unfolded flat without being inclined by the lower fill 100 or the pedestal as indicated by reference numeral 24A, in particular, referring to FIGS. It is wider than the plane 23 'and may be folded to an area corresponding to the plane 23' of the processing space 23 when inclined by the lower fill 100 or the pedestal.

Here, the bottom member 24 may be inclined in any form.

As a preferred example, as shown by the arrow B of Figs. 2 to 6, the bottom member 24, by the bottom fill 100 or the pedestal, both edges from the center portion along the effluent treatment direction (arrow L) It can take the form of inclined downward to both sides. In this case, the sludge S flows down to both edges along the dirty water treatment direction (arrow L).

As another example, as shown in FIG. 7, the bottom member 24 is inclined downward from both edges toward the center portion from both edges along the effluent treatment direction (arrow L) by the lower fill 100 or the pedestal. Can take the form. In this case, the sludge S flows down to the center portion along the dirty water treatment direction (arrow L).

Although not illustrated as another example, the bottom member 24 may be inclined in one direction or three or more directions by the lower fill 100 or the pedestal, and may be inclined in part. In addition, the bottom member 24 may take an inclined form in any form as long as it can facilitate the treatment of the sludge (S).

As the treatment tank 20 is configured as described above, sludge S in the wastewater is precipitated in the treatment space 23 of the treatment tank 20, and the precipitated sludge S forms an inclined surface of the bottom member 24. Therefore, it can flow down and be collected under the inclined surface of the bottom member 24.

Therefore, the sludge S in the processing space 23 can be collected on one side by the bottom member 24, so that the sludge S in the processing space 23 can be easily and quickly processed.

In addition, the sludge (S) is collected on one side by the bottom member 24 can be more easily aggregated and concentrated with each other, the sludge (S) moisture content is sharply lowered by the precipitation of a larger amount of sludge (S). Thus, the wastewater treatment efficiency can be very excellent.

Furthermore, at least a portion of the lower end 22A of the side wall member 22 may be inclined to correspond to the bottom member 24 inclined by the lower fill 100 or the pedestal.

Therefore, the bottom member 24 can be easily inclined by the lower fill 100 or the pedestal in the unfolded state without being wrinkled, and the side wall member 22 is bent or crushed as the bottom member 24 is inclined. It can prevent it from being supported.

In addition, the treatment tank 20 easily discharges and treats the sludge S deposited in the treatment space 23 of the treatment tank 20 according to the wastewater treatment, out of the treatment space 23 of the treatment tank 20. To this end, at least one sludge discharge part 21 may be provided.

That is, as the sludge discharge part 21 is provided, the sludge S is discharged through the sludge discharge part 21 even though the treatment tank 20 is not dismantled or an operator does not enter the treatment space 23 of the treatment tank 20. It can be easily discharged.

Such sludge discharge portion 21 may be provided anywhere in the treatment tank 20, but in particular by the inclined surface of the bottom member 24 in the portion corresponding to the lower side of the inclined surface of the bottom member 24 of the side wall member 22. Since sludge S is collected, it can be said that it is more preferable to be provided in this part.

In addition, the sludge discharge part 21 is preferably opened only when the sludge (S) discharged to prevent leakage of filthy water, for this purpose it may be provided to open and close by a zipper (zipper) or Velcro tape method or a valve may be provided. have.

Meanwhile, the treatment tank 20 is a flexible material such as a tent or a liner so that it can be disassembled and transported so that it can be unfolded or folded into a small volume for septic water treatment, such as a tent. It can be formed as. That is, the side wall member 22 of the treatment tank 20 may be more preferably formed of a flexible material together with the bottom member 24.

Accordingly, the wastewater treatment unit may take a disassembled and transported assembly and a mobile structure.

In addition, since the treatment tank 20 can take an integral structure composed of one member, such as a tent, rather than a detachable structure assembled and disassembled by a plurality of members, the assembling and dismantling of the treatment tank 20 is faster. It may be easily and easily made, and the airtightness may be sufficiently maintained so that filthy water is not leaked, and thus, an additional member such as an airtight material for the airtightness of the treatment tank 20 may not be required.

In addition, the flexible treatment tank 20 may have a tube structure that can be expanded or contracted.

Accordingly, during installation, the treatment tank 20 may be expanded by the expansion pressure to maintain the expanded shape in order to treat the sewage, and during dismantling, the treatment tank 20 may be contracted by the release of the expansion pressure. It can be easily folded into small volumes. At this time, the treatment tank 20 may be any method as long as it can be easily expanded and contracted, such as pneumatic or hydraulic pressure, hydraulic pressure, filler.

Meanwhile, the treatment tank 20 may have an open structure in which at least a portion of the upper surface is opened as well as the sealed structure, and in the latter case, the assembly / disassembly operation of the wastewater treatment unit may be performed as well as the treatment tank 20. It may be advantageous that the easier and purified water purification process can be easily identified with the naked eye.

Such a flexible treatment tank 20 is structurally weak to withstand the water pressure caused by the inflow of tainted water, and thus may be more preferably supported by the rigid frame 25.

That is, by the frame 25, the treatment tank 20 can maintain the shape for the wastewater treatment while withstanding the hydraulic pressure due to the inflow of the wastewater.

At this time, it may be more preferable that the frame 25 also takes the assembling and movable structure together with the treatment tank 20 as described above.

For example, the frame 25 is coupled to the upper end of the treatment tank 20, a plurality of edge members (25A) that can be connected to each other in a ring shape, and are installed on the outside of the treatment tank 20 It may be configured to include a plurality of supporting members (25B) connected to be detachable with a plurality of edge members. In this case, the plurality of frame members may be coupled to the treatment tank 20 to be detachable by being inserted into the insertion portion provided at the upper end of the treatment tank 20. Such a frame 25 may be formed of various materials, such as plastic, aluminum, steel, depending on the water pressure.

The treatment space 23 of the treatment tank 20 may include a plurality of partition members that divide the treatment space 23 so that the filthy water can be treated in multiple stages, as shown by arrow A of FIG. 2. have.

That is, the plurality of partition members may be configured to include a porous rectifying wall 30, and the partition wall 50 so that the filthy water can be treated in the order of the precipitation step, rectification step, discharge step described above with reference to FIG. have.

First, the porous rectifying wall 30 may be provided to partition the initial settling space (23A) and the rectifying space (23B), the flow of muddy water from the initial settling space (23A) to the rectifying space (23B), of course, rectification In order to stabilize the flow of the space 23B and to prevent the movement of the floating sludge S in the initial settling space 23A, a plurality of holes 30A through which filthy water passes may be formed.

Here, although not shown, the porous rectifying wall 30 may be provided so that the filthy water can flow only through a plurality of holes, but as shown in order to prevent the overload of the filthy water by the porous rectifying wall 30. It may be more preferable to be provided as follows.

That is, the porous rectifying wall 30 may be provided at a predetermined height (for example, about 30 cm) from the bottom of the treatment space 23 to allow the flow of dirty water through the lower side of the porous rectifying wall 30. .

Alternatively, although not shown, the porous rectifying wall 30 is provided from the bottom of the processing space 23 to a predetermined height so as to contact the bottom of the processing space 23, and at least a portion of the lower end thereof is connected to the waste water for the flow of the dirty water. It may be provided to be flapping by.

In addition, the partition wall 50 partitions the rectifying space 23B and the discharge space 23C, and in particular, the flow of the filthy water toward the discharge space 23C is upwardly upward so that the effluent can be discharged as overflowed as described above. It may be provided to guide to.

To this end, like the porous rectifying wall 30 described above, the partition wall 50 has a predetermined height (eg, 30 cm) from the bottom of the treatment space 23 to allow the flow of dirty water through the lower side of the partition wall 50. Degree) can be provided with play. Alternatively, the partition wall 50 is provided to reach a predetermined height from the bottom of the processing space 23 to reach the bottom of the processing space 23, so that at least a portion of the lower end thereof can be fluttered by the tapping water for the flow of the tapping water. It may be provided.

The above-mentioned porous rectifying wall 30 and the partition wall 50 may be integrally coupled so as not to be separated from the treatment tank 20 by welding or sewing. Or in particular, as shown in 'A' of Figure 3 porous rectifying wall 30, the partition wall 50 is at least a part of the treatment tank (zipper 40 or Velcro tape method, etc.) for assembly, removable structure 20) to be detachably coupled.

In addition, the porous rectifying wall 30, the partition wall 50 may be formed of a flexible material for the assembly, movable structure with the treatment tank 20.

On the other hand, in the discharge space 23C of the treatment tank 20, a flow path 60A through which the discharged treated water passes is formed, and a filter medium 60 for adsorbing sludge S from the supernatant water passing through the flow path 60A is provided. Can be.

That is, the sludge S contained in the supernatant discharged from the discharge space 23C, in particular, the sludge S suspended in the form of fine particles is adsorbed and removed by the filter medium 60, so that the effluent water treatment efficiency is more excellent. Can be done.

Such a filter medium 60 is particularly provided so that the flow path 60A is inclined at a predetermined angle with respect to the vertical direction, so that the sludge S can be more effectively adsorbed.

The filter medium 60 may also be detachably coupled to the treatment tank 20 for the above-described assembly and mobile structure, and the filter medium 60 itself may also be formed in a flexible structure for the assembly and mobile structure, rather than a solid structure. .

In addition, the sewage water inlet 10 may be connected to the initial settling space 23A of the treatment tank 20 to guide the inflow of the wastewater, and the treated wastewater may be connected to the discharge space 23C of the treatment tank 20. That is, the discharge part 15 may be provided on the upper side of the treatment tank 20 to be discharged while the treated water overflows.

Here, it may be more preferable that the contaminated water inlet 10 is configured as follows, particularly with reference to FIGS. 8 to 10.

The end portion 12A of the processing space 23 side of the inflow pipe 12 may be provided anywhere, such as an upper portion, a lower portion, a central portion of the processing space 23, but is provided at a lower portion of the processing space 23. It may be more preferable as follows.

That is, since the sludge S is suspended in the case of fine particles, it is difficult to settle and settle because of flotation, so that the sludge S is agglomerated to form a mass of relatively heavy particles. Therefore, the contaminated water of the sludge S may be activated by the inflow of the wastewater by the inflow pipe 12 into the lower portion of the treatment space 23 in which the sludge S is settled and settled.

In addition, turbulent flow can be formed as one of the measures for activating the flocculation of the sludge (S), the filthy water is introduced into the water in the treatment space 23 by the inlet pipe 12 and treated by the inlet pressure of the filthy water. Sufficient turbulent flow can be formed by activating the sludge S precipitated and settled in the lower portion of the space 23.

As a result, the sedimentation and sedimentation efficiency of the sludge S is very excellent, and accordingly, the sewage water purification treatment efficiency is very excellent.

Here, it is more effective that the end portion 12A of the processing space 23 side of the inflow pipe 12 is provided at a lower position as close to the bottom surface of the processing space 23 as possible, but if it is too low, the processing space 23 The sedimentation, sedimentation sludge (S) due to the weight of the sewage water may be hindered or turbulence may be reduced, it is more preferably provided to be spaced a predetermined height from the bottom surface of the treatment space (23) Can be.

Further, in order to further activate turbulent flow, the end portion 12A of the processing space 23 side of the inflow pipe 12 has a processing space 23 toward the upper side thereof, as shown in FIG. 8 and FIG. 10. At least one hole 12B may be formed so as to form an upward flow as it flows into the backplane.

On the other hand, the contaminated water inlet 10 is particularly shown in Figure 9, so that it can be rotated by the contaminated water flowing into the processing space 23 from the inlet tube 12, of the inlet tube 12 The cap 14 may further include a cap 14 installed at the end portion 12A of the processing space 23 and having at least one hole 14A communicating with the inflow pipe 12.

That is, as the cap 14 is rotated by the inflow of the wastewater, the turbulent flow may be more activated as the wastewater flows into the treatment space 23 while forming the upflow as well as the rotational flow from the inflow pipe 12. have.

Here, the number and shape of the holes 14A of the cap 14 may be variously designed to form a rotational flow, and the cap 14 may be rotated by the inflow force of the tap water as a non-powered drive. As shown in FIG. 9, the wing 14B may be further provided to more smoothly rotate the cap 14 due to inflow into the wastewater.

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.
