Description

TECHNICAL FIELD [0001] The present invention relates to a non-point pollution reduction facility for a non-point pollution control facility,

The present invention relates to a non-point pollution abatement facility, and more particularly, to a non-point pollution abatement facility having a power-type non-point pollution abatement facility which is capable of backwashing a filter medium to remove foreign substances in the rainwater, .

The pollutants originating from the urban areas are classified into point pollutants and nonpoint pollutants. Point pollution sources can predict the location and time of pollution due to pollution such as waste water in factories, but non-point pollution sources are sources of pollutants exposed to the ground surface during rainfall, There are features that do not. The nonpoint source is characterized by the concentration of runoff at the beginning of rainfall.

Nontoxic pollutants included in the initial rainfall are introduced into the public waters to cause contamination of rivers and lakes, and also penetrate into the underground and become a factor causing contamination of groundwater resources. Therefore, the pollutants that are introduced together with the initial rainwater must be discharged to the discharge water through purification and purification processes.

There are a variety of early storm water treatment systems, such as a storage type such as artificial wetland, a filtration type such as filtration tank, and a device type such as a swirl treatment device, Each of the processing apparatuses has advantages and disadvantages.

1 includes a sedimentation tank 10, a filtration tank 20, a storage tank 50, a congestion water discharging means, a reverse conveying unit, and an aeration unit as a filtration type. Solid foreign matters such as soil and coarse particles are precipitated and separated in the sedimentation tank 10 of the non-point pollution source treatment apparatus, and fine solid impurities or floating matters in the precipitate treated in the filtration tank 20 are filtered and adsorbed . The filtrate treated in the filtration tank 20 flows into the storage tank 50 and stays, and is discharged to the outside through the discharge pipe 55.

A baffle plate (15) is installed inside the settling tank (10). The sedimentation tank 10 has a space of a certain size formed therein. An inflow pipe (11) is installed on the upper side of the sidewall of the settling tank (10) so that storm can be introduced into the settling tank (10). The baffle plate 15 is vertically installed in the sedimentation tank 10. The lower end of the baffle plate 15 is formed to be spaced apart from the bottom of the settling tank 10. The baffle plate 15 relaxes the flow of the fluid and improves the settleability of the foreign matter.

Soils, sand, heavy metals, and the like, which are foreign matter having a relatively large specific gravity and flow into the sedimentation tank 10 through the inflow pipe 11 at the time of rainfall, are precipitated at the bottom of the sedimentation tank 10, Etc. are mixed with the rainwater and flow into the filtration tank 20.

The rainwater flowing out from the settling tank 10 in the filtration tank 20 passes through the filter material accommodation chamber in which the fluid phase filter material 27 is accommodated, and the remaining foreign matter is removed. The filtration unit 20 includes a diaphragm 21 for partitioning the interior of the filtration tank 20 into a first space unit and a second space unit, and a filter material accommodation chamber accommodating the fluid phase filter material 27. The filtration tank 20 is installed at the rear end of the settling tank 10. The filtration tank 20 and the settling tank 10 are separated by a partition 19. The partition wall 19 is formed with an excellent moving hole 18 so that the storm can be introduced into the filtration tank 20 from the settling tank 10. A screen for removing foreign substances is provided in the fine movement hole (18). The bottom 29 of the filtration tank 20 is formed at a position higher than the bottom of the settling tank 10, while the upper surface of the filtration tank 20 is the same as the upper surface of the settling tank 10. The diaphragm 21 is vertically installed inside the filtration tank 20 and divides the inside of the filtration tank 20 into two spaces. The diaphragm 21 is divided into a first space 31 forming a downward flow which flows in through the fine moving hole 18 and a second space 31 forming an upward flow by flowing in the first space 31. [ (33). A connection hole 22 is formed in the lower portion of the partition wall 21 so that the rainwater can flow into the second space portion 33 from the first space portion 31.

The filter material accommodation chamber accommodating the fluid phase filter 27 is provided on the upper side of the second space portion 33. The filter media compartment is composed of an upper net 23 and a lower net 25 to limit the flow range of the fluid media 27. The upper and lower webs 23 and 25 are made of a net structure so as to block the flow of the high-phase filter medium 27 and allow the high-quality flow to pass therethrough. The fluid filtering medium 27 is accommodated between the upper net 23 and the lower net 25. The fluid filtering medium 27 flows through the space defined by the upper net 23 and the lower net 25 and filters out the rainwater. In addition, the fluid phase filter 27 is excellent in adsorbing ability and can effectively remove colloidal suspended solids. The microorganism can be fixedly used in the fluid phase filter material 27. The fluidized media (27) should have a large surface area and be able to flow with the flow of water. Therefore, the fluid phase filter material 27 is preferably a porous structure having a specific gravity of 0.4 to 0.8 and a pore size of 10 to 50 PPI (pores per inch). As the material of the fluid phase filter having such characteristics, a network type polyurethane foam having a light and porous structure can be used. The fluid phase filter 27 may be formed in various shapes. For example, a shape such as a sphere, an ellipse, or a square. Unlike the example shown in FIG. 1, the filter media storage chamber may have a plurality of unit cartridges arranged at regular intervals. In this case, the unit cartridges are formed in the shape of a quadrilateral tube, and the fluid image filter can be accommodated in the unit cartridges. It is needless to say that the unit cartridge is made of a net so that water can be flown in and out. And the filtration treated water flows into the storage section 50 while passing through the filter media storage room. For this purpose, a fine movement hole 45 is formed on the upper side of the partition wall 40 separating the filtration tank 20 and the storage portion. The bottom of the storage section 50 is formed at a lower position than the bottom of the filtration tank 20 and is formed at the same position as the bottom of the settling tank 10. [ The stormwater flowing into the storage tank (50) is discharged to the outside through the discharge pipe (55). The discharge pipe (55) is provided on the upper side of the side wall of the storage part (50). Therefore, when the level of the rainwater flowing into the storage section 50 reaches the height of the discharge pipe 55, it is discharged to the outside.

On the other hand, a cleaning means capable of backing up the filter media is required to prevent the foreign matter from adhering to the surface of the fluid phase filter material 27 to prevent the filtration efficiency from being lowered. To this end, the present invention comprises a venting portion and a reverse conveying portion. Air is blown out from the lower portion of the filter material storage room to thereby remove the foreign matter adhered to the fluid filter material 27. [ An air supply pipe 83 connected to the air compressor 80 and extending to the inside of the filtration tank 20 and an air supply pipe 83 installed in the air supply pipe 83 to receive the filter media And an injection nozzle 85 for spraying air.

The injection nozzle 85 is disposed below the lower net 25 and spaced downward. The high-pressure air injected through the injection nozzle 85 collides with the fluid phase filter 27, thereby removing the foreign matter adhering to the surface. The reverse transit section injects stagnant storms into the interior of the filtration tank 20 in the storage tank 50 to desorb the foreign substances adhering to the fluidized media 27. This reverse feed has the function of cleaning the filter media and functioning to reverse the stagnant storm to the filtration tank. A pump 90 provided in the storage tank 50 and a spray pipe 95 provided above the filter material storage chamber are connected to the discharge port of the pump 90 and the other end is connected to the discharge pipe 95 (Not shown). A pump (90) is installed at the bottom of the reservoir (50) to pump the congestion water stagnated in the reservoir (50). The injection pipe 95 is connected to the connection pipe 93 and is installed above the filter material storage room. The high-pressure stagnant water sprayed through the spray tube 95 can effectively remove foreign matters adhered to the surface of the fluid phase filter material 27. When the inflow of stormwater through the inflow pipe 11 is stopped, stagnant storms in the settling tank, the filtration tank and the storage section are filtered and discharged to the ground.

A first opening and closing member 101 installed in the first drainage passage for opening and closing the first drainage passage and a drainage tank 60 provided below the filtration tank 20, A second opening and closing member 105 installed at the second drainage passage for opening and closing the second drainage passage, a water spraying pipe 65 connected to the second drainage passage and extending into the drainage tank 60, And a porous pipe 67 installed at the filtering unit 70 and connected to the ground at the bottom. The first drainage passage is formed in the partition 19 so as to be close to the bottom 29 of the filtration tank 20. Therefore, the stagnant water level of the settling tank 10 is opened or closed.

The discharge tank (60) is installed below the filtration tank (20). The bottom of the discharge tank (60) is formed at the same height as the bottom of the settling tank (10). The discharge chamber (60) is also separated from the settling tank (10) by a partition (19) separating the filtration tank and the settling tank. A second drainage passage is formed in the partition wall 19 so that a stagnant storm can be introduced into the discharge vessel 60 in the sedimentation tank 10. And the second drainage passage is formed at a position lower than the first drainage passage. And the second opening and closing member 105 is provided in the second drainage passage. The water spray pipe (65) is connected to the second drainage line and extends into the discharge tank (60). A plurality of holes are formed in the water spray pipe (65). When the second drainage passage is opened by the second opening and closing member 105, the stagnant stagnant water in the settling tank 10 is sprayed into the discharge tank 60 through the spray pipe 65.

A filtering unit 70 for filtering stagnant water introduced into the discharge tank 60 is installed in the discharge tank 60. The filtering unit 70 is formed by laminating a plurality of filter media having different particle sizes. A mixture of sand and a carrier is mixed on the bottom of the discharge tank 60 to form a first filter layer 71 and a second filter layer 73 is formed on the first filter layer to form a second filter layer 73. On the second filter layer, The third filter layer 75 may be formed.
