Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upflow and non-residue processing apparatus for treating polluted water including rainfall runoff,

The present invention relates to a rainwater effluent treatment apparatus in a sewage treatment plant, and more particularly, to a rainwater effluent treatment apparatus in a sewage disposal plant, particularly in a construction site, an industrial complex, a road, and the like to remove rainwater (P) The present invention relates to an upflow and a non-residual treatment apparatus for treating a contaminated water including rainfall runoff which can prevent runoff from remaining.

Generally, water pollutants can be classified into point pollutants and nonpoint pollutants.

Point pollutants are constantly generated at relatively constant points such as domestic sewage, factory wastewater, and industrial wastewater, and there is no significant variation in their emissions during rainfall or non-rainfall, while non- Contaminants that run out along with runoffs are dust and waste in urban areas, fertilizers and pesticides sprayed on agricultural land, soil decay plants, housing spills, and air descent, which are released from large areas.

These non-point pollutants are difficult to predict and quantify because of the large changes in seasonal emissions, and are difficult to control due to weather conditions, topography, and geology.

Also, due to development projects, the impact of nonpoint pollution sources on water quality is increasing day by day.

In terms of pollutant management and reduction, many pollutants have been reduced due to the development of treatment methods and the construction of new wastewater treatment plants. However, the methods and apparatuses for treatment of nonpoint pollutants are still in short supply. It is difficult to improve the quality of water further by the centralized water quality policy. Due to the increase of the impervious rate of the region due to urbanization, the storm drainage characteristic of the region is changed and various pollutants from the water quality are discharged to the water system together with the rainwater runoff, It is necessary to actively manage stormwater runoff to improve water quality of rivers and lakes due to non-point pollutants.

Currently, the non-point pollutant removal system, which is widely used, has a method of precipitating suspended matters by causing a swirling flow in the rainwater flowing into the inside, and purifying the effluent of the precipitated precipitates through a filter material such as activated carbon.

However, the apparatus for removing non-point pollutants as described above has a problem that the treatment efficiency of pollutants is low and maintenance is difficult.

In particular, there is a problem that nutrients such as phosphorus (P) generated by the use of pesticides in paddy fields and fields can not be removed.

When the suction force is applied by the suction pump (not shown) connected to the pump suction port 433, the hollow shaft 432 is connected to the bell mouth 431, Is raised upward along the hollow shaft 432 and is discharged to the outside of the purging chamber 100.

On the other hand, a shaft fixing base 314 is installed on the second front and rear partitions 310 to prevent the hollow shaft 432 from moving.

The scum removing means 440 includes a vertical partition wall 441 installed between the second front and rear partition wall 310 and the third front and rear partition wall 410 and installed across the front and rear faces of the purge chamber 100, A connecting panel 442 having one end disposed at an upper end of the vertical partition wall 441 and the other end extending horizontally toward the second front and rear barrier ribs 310; And a perforated panel 443 having a plurality of through holes 443a.

The vertical partition wall 441 is connected to both the front and rear sides of the front surface of the purging chamber 100.

The perforated panel 443 is formed with a through hole 443a of a predetermined size so that the scum floating on the rain water runoff is caught in the through hole 443a.

The filtration part 500 is formed between the third front and rear partitions 410 and the right side surface of the purging chamber 100. An activated carbon filtering device 510 is installed to remove the filtered rainfall water from the purging chamber 100 Is discharged through the first outlet pipe (120).

A plurality of outlets 410a are formed in the front lower side of the third front and rear partitions 410 so that the rain water can be gradually raised from the lower side of the filtration part 500 to the upper side.

The activated carbon filtering apparatus 510 includes a mesh network 511 having both ends fixed to the inner surface of the second front and rear partitions 310 and the purging chamber 100, And activated carbon 512, Accordingly, the oil is removed while the second front and rear partition walls 310 are flowing, the sludge is removed through the sludge removal means 430, and the scum is removed while passing through the perforated panel 443 installed in the vertical partition wall 441 The rainwater runoff gradually flows upward and flows through the mesh net 511 of the activated carbon filtration apparatus 510 so that the foreign matter flows into the filtration unit 500 through the entrance 410a of the third front- And is purified while passing through the activated carbon 512. [

The outflow part 600 is formed between the filtration part 500 and the rear surface of the purging chamber 100 and is provided with a weir adjusting device 610 on the rear side of the third front and rear partitions 410, 2 is a place where the rainwater runoff is discharged through the discharge pipe 130. That is, the outflow part 600 includes a rear partition wall 520 installed at the rear side of the third front and rear partition wall 410, the right side inner side and the rear inner side of the purge chamber 100, and the rear part of the filtration part 500 ). &Lt; / RTI >

The rear side of the third front and rear partitions 410 is formed to be lower in height than the front side. That is, the third front-rear partition 410 constituting the filtration unit 500 is connected to the upper surface of the purge chamber 100. However, the third front-rear partition 410 constituting the outflow unit 600 The upper end is spaced from the upper surface of the purge chamber 100 by a predetermined distance and is formed at the same height as the second front and rear partition 310 and the vertical partition 441.

The reason why the height of the front side and the rear side of the third front and rear partition wall 410 are different from each other is that when the activated carbon filtering apparatus 510 of the filtration unit 500 increases the filtration pressure during the filtration of the rainfed water, And the water level of the rainfall runoff flowing into the third front-rear partition wall 410 becomes higher.

That is, since the rising water flow rate can not be kept constant, the rainfall effluent flows into the outlet portion 600 through the rear side of the third front and rear partition 410 having a low height, And the rainwater effluent flowing into the outlet 600 is discharged to the outside through the second outlet pipe 130 of the purge chamber 100.

The weir adjuster 610 includes a main body 611 installed on the upper surface of the purifying chamber 100, a shaft 612 which is vertically movable and fixed to the main body 611, And a weir 613 connected to the lower end of the shaft 612 and closely attached to the rear side of the third front and rear partition 410. The reason why the weir adjuster 610 is installed is that it is necessary to stagnate the rainwater in the purge chamber 100 for a while without discharging the rainwater to the outside of the purge chamber 100 through the third front and rear partitions 410 It is because.

That is, when toxic substances are contained in the rain water runoff or other deadly substances are mixed, the shaft 612 is raised to raise the weir, thereby widening the space where rainwater runoff can be stored.

A medicine injector 700 is further provided between the upper surface of the purging chamber 100 and the inflow section 200 with a medicine injector 720 for removing phosphorus contained in the rainwater runoff . A bottom partition wall 710 connected to an upper end of the first front and rear partition wall 210 is provided between the left side of the purge chamber 100 and the middle partition wall 330, A medicine dispensing part 700 is formed on the upper side.

The medicine introducing means 720 includes a medicine tank 721 in which medicine for removing phosphorus P is stored and a medicine dispenser 720 connected to the medicine tank 721 to move medicines for removing phosphorus and to which a solenoid valve 722a is installed A control unit 723 electrically connected to the solenoid valve 722a to open and close the solenoid valve 722a and a controller 723 for sensing the level of the rainwater runoff in the inlet unit 200, And a level sensor 724 for transmitting a level sensing signal to the level sensors 723 and 723.

The level sensor 724 is installed to measure the level of the rainwater flowing into the inflow section 200. More specifically, the level sensor 724 is installed on the rear side of the inflow section 200, The partition wall 230 is formed to have a predetermined height at the left side of the first partition wall 210 and the first front and rear partition wall 210. The rainwater effluent flowing into the inlet 200 is stored up to a predetermined height by the partition wall 230 The water level will rise. As the water level continues to rise, the rainwater runoff flows through the barrier ribs 230 to flow into the coagulated floccules 300.

Since the ball tap water level meter 725 installed in the medicine dispensing means 720 is widely used in other technical fields in the related art, a detailed description thereof is avoided here.

The lower surface of the purging chamber 100 is inclined downward at a predetermined angle from the rear side to the front side and a drain device 800 is installed on the front surface of the purging chamber 100, The runoff water flowing inward is discharged to the outside.

The drain device 800 is installed on the front side of the purge chamber 100 of the inlet 200, the agglomerate 300 and the foreign material removal unit 400, and a drain filter 810 is installed therein A drain chamber 830 in which a cover 820 having a plurality of through holes 820a formed on the upper side thereof is installed and a drain chamber 830 connected to the drain chamber 830 to receive the rainwater effluent flowing through the drain filter 810, And a drain pipe 860 in which a mesh network 840 having a built-in mesh network 840 is installed.

This drain device 800 prevents rainwater effluent remaining in the purging chamber 100 from being corrupted when the rainwater effluent treatment apparatus according to the present invention is not used for a long period of time have.

The drain pipe 860 of the drain device 800 is connected to a first discharge pipe 900 and the first discharge pipe 120 and the second discharge pipe 130 are connected to a second discharge pipe 910 The first discharge pipe 900 and the second discharge pipe 910 are connected to each other to be connected to each other and are discharged to the first discharge pipe 120, the second discharge pipe 130 and the drain pipe 860 Allow the rainwater runoff to be directed to one location.

The other end of the vertical partition 311 is connected to the vertical partition 311 of the intermediate partition wall 330 and the vertical partition 311 of the second front and rear partition wall 310, Rear partition wall 410 through the vertical partition wall 441 of the first and second front and rear partition walls 440 and 440, respectively. The reason why the late storm drain pipe 231 is installed is that the initial storm drainage water contains a large amount of contaminants but the latter storm drainage water does not contain much contaminants. Therefore, when the late storm drainage water flows into the inlet unit 200 It is not necessary to use various facilities according to the invention, for example, the drug dispensing means 720, the sludge removing means 430, the scum removing means 440, the drain device 800, and the like.

Accordingly, the late storm water is led to the outflow section 600 through the late storm drain pipe 231, and the latter storm drain water is discharged to the outside through the second drain pipe 130 and the second drain pipe 910 .

12 to 14, the integrated discharge pipe (TD, see Fig. 13), in which the first discharge pipe 900 and the second discharge pipe 910 are integrated, The flocculation unit AD and the dewatering unit SC are further disposed at the upper and lower ends of the drainage pipe so as to finally completely flocculate and remove the trace phosphorus component contained in the drain water.

At this time, as shown in FIGS. 12 and 13, the flocculating unit AD is fixedly installed on the support frame 12 with a rotary conductor 14. As shown in FIG.

A cylindrical fixing block 16 protrudes from the center of the rotating derivative 14, and a plurality of discharge holes 18 are formed on the bottom surface of the rotating derivative 14 at intervals in the circumferential direction.

In this case, the support frame 12 has a lattice shape so that the support frame 12 is not disposed below the discharge hole 18. Accordingly, the fallen object dropped through the discharge hole 18 is naturally drawn into the dehydration unit SC).

A rotary cylinder 20 is inserted around the rotary conductor 14. The rotary cylinder 20 is hollowed at the center and can be fitted to the rotary conductor 14, And a dam 24 is formed along the circumference of the outer circumference to form a wall so that an object charged into the inside can not escape out of the case, As shown in FIG.

In addition, a gear is formed on the outer surface of the dam 24 in a circumferential direction, and a driving gear 26 is coupled to the gear, and the driving gear 26 is connected to the rotary motor 28.

Accordingly, when the rotation motor 28 rotates, the driving gear 26 rotates and pushes the dam 24 in the radial direction. Therefore, the rotary cylinder 20 is rotated by the rotation of the rotary induction 14 as a rotating shaft.

At this time, a plurality of idle gears 30, which have the same gear shape as the driving gear 26 but are rotated in place without power, are further provided around the rotating cylinder 20 to rotate the rotating cylinder 20 more smoothly .

A plurality of through holes (PTD) (see FIG. 13) are formed in a part of the periphery of the rotary conductor 14, and a circumferential portion of the rotary cylinder 20 has a shape corresponding to the through hole PTD A discharge inducing hole (GTP) is further formed.

Therefore, the discharge inducing hole (GTP) can be maintained in a state of being in communication with the passage discharge hole (PTD) once per rotation of the rotary cylinder (20).

Since the through-hole PTD is always kept in a fixed position, a drain-guide plate 32 is provided at the top of the bottom of the rotary cylinder 20 at the point where the through-hole PTD is formed , And the discharge guide plate (32) is connected to the discharge guide cylinder (34) so that it can move up and down.

In particular, the discharge guide plate 32 is arranged so as to be able to guide falling bodies, which are rotationally moved in a plan view, in a tilted manner with respect to the radial direction of the rotary cylinder 20 as shown in FIG. 13, to naturally pass through the discharge passage PTD .

In addition, since the rotary cylinder 20 is designed to be rotated in a clockwise direction, an integrated discharge pipe (TD) is piped right above the passing discharge hole (PTD), and the interval between the integrated discharge pipe (TD) And the coagulant supply pipe (AP) is piped.

Therefore, the coagulant is injected immediately after the discharged water containing a small amount of phosphorus (P) is discharged, thereby aggregating phosphorus (P) contained in the discharged water.

At this time, the coagulant is a well-known coagulant usually containing aluminum and iron.

Further, a dispersing plate 40 is provided at a point opposed to the through-hole PTD in the radial direction.

The dispersion plate 40 is an inclined plate which becomes thicker toward the upper part and is firmly fixed on the fixed block 16 through the fixing rod 42. [

Therefore, the flocculant and the drain water which are moved while being agglomerated are hung on the dispersing plate 40 and spread evenly over the entire bottom surface of the rotary cylinder 20. In this process, unreacted phosphorus (P) The efficiency is increased, and the phosphorous (P) removal ability is improved.

A controller (CT) is installed on the adjacent side of the rotary cylinder 20 to remove all control devices such as the rotary motor 28 and the discharge guide cylinder 34.

Particularly, in order to increase the cohesion efficiency, the rotating cylinder 20 is rotated 2-3 times slowly after a predetermined amount of discharged water is discharged through the integrated discharge pipe (TD) So that the agglomerated agglomerates are controlled to be discharged into the discharge holes 18.

The process of discharging the agglomerated agglomerates to the discharge holes 18 according to this configuration is as follows.

When it is determined that cohesion is completed by rotating the rotary cylinder 20 2-3 times slowly, the controller CT operates the discharge guide cylinder 34 to lower the discharge guide plate 32.

Then, the discharge guide plate 32 blocks a part of the rotary cylinder 20 in an oblique shape as shown in FIG. 13, so that the coagulant which has been rotated along the rotary cylinder 20 is caught by the discharge guide plate 32.

At this time, when the passage discharge hole (PTD) and the discharge inducing hole (GTD) coincide with each other, the aggregate is discharged into the rotating induction 14, and when the discharging of the flocculation material is completed by repeating this process, The next discharge water is also discharged a certain amount.

Then, the agglomerate discharged into the rotary derivative 14 falls downward and is charged into the dewatering unit SC.

On the other hand, the dehydrating unit SC includes a presser 52 directly connected to the lower portion of the accommodating bag 50, as shown in Figs. 14 and 15. Fig.

The pressing unit 52 includes a pressing housing 52a connected to the discharge port of the accommodating table 50 and a pair of rollers 52a and 52b disposed at the lower portion of the pressing housing 52a for pressing the coagulated material flowing into the pressing housing 52a. And a roll rotation motor 52b for rotating the roll rotation motor (not shown).

A cylindrical screen 54 having a plurality of fine holes is provided below the compression housing 52a and a lower canister 56 is provided at a lower portion of the cylindrical screen 54.

That is, since the cylindrical screen 54 must be dewatered, the cylindrical screen 54 is seated in the cylindrical low water tank 56 so that the dewatered water can be collected and drained.

A drain port (58) is formed on the bottom surface of the reservoir (56).

A scraper driving motor 150 is fixed to the bottom of the bottom case 56 and a scraper 62 is fixed to the rotating shaft of the scraper driving motor 60.

The scraper 62 is preferably made of a synthetic resin having elasticity.

A dehydrated water outlet 70 is formed in a part of the circumference of the cylindrical screen 54 and a storage box BOX is provided in a lower part of the dehydrated water outlet 70.

Accordingly, since the falling object is swept by the scraper 62 rotated inside the cylindrical screen 54 and is rotationally compressed, the dewatering efficiency is increased. The dewatered dewatered water is discharged through the dewatering outlet 70, And is collected in a box (BOX).

Therefore, it is only necessary to collect the collected contents of the storage box (BOX) and recycle or separate them.
