Description

Treatment System using Ultra Density Filter for Separation Solid and Oil from Water}

The present invention relates to a wastewater and a solids and oil-water separation treatment system using a polymer filter, more specifically, the high-density polymer is a non-point contaminant such as oil components and suspended solids contained in the wastewater flowing into the wastewater treatment plant or storm pipe After polyethylene particles are used, they move together between the surface and the space of a cylindrical filter, and coalesce to increase particle size. Solids of SS (Suspended solids) components are removed by sedimentation to the bottom by gravity, and oil components float on water. The present invention relates to a wastewater and rainwater solids and oil-water separation treatment system using a polymer filter to be separated by.

In general, oil-water separation facilities and non-point pollution reduction facilities (initial water treatment facilities) for separating oil or water contained in water from oil components and nonpoint pollutants flowing into wastewater treatment plants or storm pipes are It is used to remove by the difference in specific gravity of oil and water, and by the Stokes' law based on the specific buoyancy (gravity) difference of oil and water mixture and the flow of the mixture according to the buoyancy.

The removal method by the specific gravity difference between oil and water is to fix the contaminated water containing oil into the treatment tank and settle. Accordingly, since oil is lighter than water, it floats on water and condenses. It is removed by separation into the liquid phase.

However, this method is relatively easily separated when the oil droplet size is 1 mm or more, but oil droplets with a diameter of 1 to 1.5 µm that are finely divided through the flow of the fluid take a long time to separate flotation and thus have a high efficiency. Falls.

In addition, the method of removing by stokes' law based on the specific buoyancy (gravity) difference of the flowing water and the flow of the mixture according to the buoyancy is to install the effective contact area by installing several horizontal plates or parallel inclined plates in the treatment tank. COALESCING PLATE PACK type, which spreads the contaminated water containing oil components through a combination of polypropylene (POLY PLOPHYLEN) corrugated or egg-shaped plates in multiple stages.

However, in such a method, when used for a long time, viscous sludge combined with oil components and suspended solids is deposited between the bonded multi-stage corrugated board or egg board, thereby preventing the passage of fluid.

This disruption of the fluid flow delays the oil / water separation treatment, which in turn leads to a decrease in treatment efficiency. In particular, the conventional oil-and-water separation media can perform the oil-water separation function only on the light oil having a low viscosity of the oil. However, if the viscosity is high, such as grease, bunker C oil, animal oil, etc. stuck between the multi-stage corrugated or egg plate to block the plate coalescence pack, there is a problem that the versatility can not be performed because the oil and water separation function can not be performed.

As described above, the two oil-water separation methods have a disadvantage in that the treatment efficiency decreases, and in order to increase the treatment efficiency as the treatment efficiency decreases, the area of the oil-water separation treatment facility becomes large and the cost of construction of the treatment facility is high. There is this.

In addition, when the amount of contaminants accumulated in the treatment tank reaches a certain amount due to the delay of oil / water separation treatment, the filter network is blocked and the influent contaminants are overflowed, and the inflow of backwater occurs, thereby losing the normal treatment function.

The present invention is to solve the above-mentioned problems, the purpose is to efficiently remove the solids of SS components and oil components by using a polymer filter formed of a cylindrical structure having a small weight compared to the volume surface area using a high-density polymer polyethylene material The present invention provides a wastewater and rainwater solids and oil / water separation treatment system using a polymer filter capable of separating from water.

Another object of the present invention is economical because it is possible to remove the solid matter and oil and water separation only by the physical action of the polymer filter, the filter is only by spraying high-pressure air or water in the state that the filter is filled in the filter cylinder when cleaning the filter The present invention provides a wastewater and rainwater solids and oil / water separation treatment system using a polymer filter that can be easily removed to deposit solids.

The present invention for achieving the above object has a first treatment tank for storing the treated water containing an inlet for the inflow of treated water and an outlet for discharging the treated water and containing oil components and non-point source materials, and the first It is formed by filling the polymer filter in the filter cylinder which is installed on the outlet side of the treatment tank and is capable of penetrating the treated water, and removes the solids from the treated water passing through the filter cylinder to drop to the bottom of the first treatment tank, oil component A solids remover which floats and is discharged through the outlet together with the treated water, an inlet connected to the outlet of the first treatment tank, and a discharge port for discharging the treated water, and a second treatment tank for storing the treated water flowing into the inlet; And a polymer filter in the filter cylinder which is installed at the inlet side of the second treatment tank and is capable of penetrating the treated water.

The system is characterized.

In addition, the present invention has a discharge port connected to the inlet of the first treatment tank and the inlet through which the treated water flows in, and stores the treated water introduced from the inlet to remove solids from the treated water to the bottom to remove and float the floating and oil components Characterized in the wastewater and rainwater solids and oil-water separation treatment system using a polymer filter further comprising a pretreatment tank to separate.

In addition, the present invention has a inlet connected to the outlet of the second treatment tank and a discharge port for discharging the treated water, a third treatment tank for storing the treated water introduced from the inlet, and the treatment is installed in the treatment tank and introduced through the inlet It is characterized by the wastewater and rainwater solids and oil-water separation treatment system using a polymer filter further comprising a nonwoven filter for removing heavy metals and water-soluble oils from water.

In addition, the present invention is to set the water level of the pre-treatment tank, the first to the third treatment tank gradually lower so that the treated water is separated from the wastewater and the solids and oil water of the wastewater using a polymer filter that is induced in a non-powered flow from the pretreatment tank to the third treatment tank. It is characteristic of the processing system.

In addition, the present invention is the polymer filter is made of an ultra-high molecular weight polyethylene material, is formed of a hollow cylinder having a diameter of 14 ~ 30mm, 50 ~ 85cm in length, 0,01 ~ 0.08mm in thickness, the length of the cylindrical body It is characterized by the wastewater and rainwater solids and oil-water separation treatment system using a polymer filter configured to elastically deform and restore the outer shape of the cylindrical body by the external force acting on the cylindrical body formed by the spiral cut in the direction.

In addition, the solids remover of the present invention is filled with a polymer filter in the range of 80 to 85% of the total volume of the filter cylinder, the upper and lower parts of the filter cylinder on the discharge side of the back is closed by the respective closed length, respectively, The closed length of is characterized by wastewater and sewage solids and oil-water separation systems using polymer filters equal to 1/4 of the total height.

In another aspect, the present invention is characterized in the wastewater and the excellent solids and oil-water separation treatment system using a polymer filter formed by communicating the first and second cylinders in which the filter cylinder of the solids remover is inclined with respect to the flow direction of the treated water.

In addition, the present invention is characterized in that the wastewater and the excellent solids and oil-water separation treatment system using the polymer filter formed in a rounded shape in which the through portion forming the treated water inlet and outlet of the filter cylinder becomes narrower in the direction in which the treated water flows.

In addition, the present invention is produced to float between the surface of the oil layer and the surface of the surface of the treated water stored in the second treatment tank to rise and fall in accordance with the increase and decrease of the water level, and rises in accordance with the water level of the treated water The waste water and the excellent solids and oil-water separation treatment system using a polymer filter further includes an oil discharge blocking device made of a guide body for guiding the descending floating body to the discharge port to close the discharge hole when the floating object is lowered. have.

According to the wastewater and the excellent solids and oil-water separation treatment system using the polymer filter of the present invention, the solids of the SS component from the treated water by the polymer filter formed of a cylindrical structure having a small weight relative to the volume surface area using a high-density polymer polyethylene material Removal of oil and separation of oil components improves solids removal and oil / water separation performance.So, it is possible to remove solids and oil / water separation only by physical action by polymer filter. It is easy to maintain and economical because it does not need a separate power unit, and it is excellent in versatility because it shows its effects on various kinds of oils.

In addition, according to the present invention, as the cylindrical body of the polymer filter elastically deforms and restores during solids removal and oil / water separation, the floating of coalesced oil components becomes smoother while moving between the surface and the space of the cylindrical body. Falling to the bottom is more smooth, so that the oil separation and solids removal performance is further improved.

In addition, the polymer filter used in the solids remover and oil / water separator of the present invention, since the elastic deformation and the restoring action of the cylindrical body shakes off the solids attached to the surface of the cylindrical body, thereby minimizing the adhesion of the solids, and thus the weight of the polymer filter. Minimizing this increase prevents the polymer filter from sinking to the bottom and losing its function.

In addition, the polymer filter of the present invention has a cylindrical configuration to remove solids attached to the surface of the cylindrical body only by high pressure injection of air or water without having to take it out of the filter cylinder during washing, and by the pressure of air or water to be injected By repeating the elastic deformation and restoring action of the cylindrical body, the attachment is more effectively removed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a cross-sectional view of the treatment system of the present invention from the front, and FIG. 2 is a plan view, and as shown, the treatment system of the present invention includes a first treatment tank 10 for removing solids from treated water and oil from the treated water. A second treatment tank 20 for separating the components, the pretreatment tank 30 for pretreating the treated water flowing into the first treatment tank 10, and the treatment introduced from the second treatment tank 20. A final third treatment tank 40 for removing heavy metals and water-soluble oils from water is further provided.

The pretreatment tank 30 includes an inlet 31 through which the treated water flows and a discharge port 32 for discharging the treated water into the first treatment tank 10. The pretreatment tank 30 floats the various floats and oil components contained in the treated water by storing the introduced treated water, and solids of the SS component are deposited to the bottom.

Therefore, the pretreatment tank 30 primarily removes the solids such as the suspended solids and the sludge including the oil components from the treated water before the solids removal and oil-water separation treatment.

The first treatment tank 10 includes an inlet port 11 connected to the outlet port 32 of the pretreatment tank 30, and an outlet port 12 for discharging the treated water. Therefore, the first treated water from the pretreatment tank 30 is introduced through the inlet 11 and stored.

The first treatment tank 10 is for removing solids from the treated water. A solids remover 50 is provided on the outlet 12 side to remove solids from the treated water and separate oil components.

The solids remover 50 includes a filter cylinder 51 made of a perforated plate having a plurality of through holes 51a so that the treated water can pass therethrough, and the polymer filter 52 is placed in the filter cylinder 51. It is configured by filling. The polymer filter 52 removes solids from the treated water passing through the filter cylinder 51 and separates oil components.

The material of the polymer filter 52 is made of ultra high molecular weight polyethylene (ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE) with a molecular weight of 9 million or more.

Generally, the properties of ultra high molecular polyethylene are known to be high in abrasion resistance, impact resistance and self-lubricating property, strong in chemical resistance and weather resistance, non-toxic and non-absorbing, and have electrical insulation and high frequency characteristics.

In addition, the structure of the polymer filter 52 is formed as a hollow cylindrical body 52a of an irregular shape having a diameter of 14 to 30 mm, a length of 50 to 85 cm, and a thickness of 0,01 to 0.08 mm as shown in FIG. By minimizing the weight compared to the volume surface area, it is possible to float in water.

If the size of the polymer filter 52 is larger than the size described above, the weight is greater than the specific gravity of the water, so that it does not float in the water and sinks, thereby preventing the oil-water separation and the solids removal function. On the contrary, if the size is made too small, the surface area is small and the oil-separation performance and the solids-removing performance are lowered. If the weight is too light, the polymer filter 52 is completely suspended above the surface of the water, which also lowers the oil-water separation efficiency.

In addition, the polymer filter 52 is formed with a cutout 52b spirally cut in the longitudinal direction of the cylindrical body 52a. The cutout 52b is elastically deformed when the external force due to the flow pressure of the fluid to the cylindrical body 52a or the close contact force between the adjacent polymer filters 52 is elastically deformed, and the external force is removed. The outer shape of the cylindrical body 52a performs a function to elastically restore.

The elastic deformation of the cylindrical body 52a is, for example, the bending or bending deformation along the direction of the external force, as shown by the virtual line (a) of FIG. In addition, a portion subjected to an external force, such as the portions indicated by b and c in FIG. 5, is eccentrically deformed with respect to the central axis X-X according to the direction of action of the external force.

It is preferable that the helical cutout 52b is formed to have an inclination angle θ of 45 degrees with respect to the central axis X-X of the cylindrical body 52a. When the inclination angle θ of the cutout 52b is smaller than 45 degrees, the elastic force of the cylindrical body 52a is so weak that the cylindrical body 52a is easily deformed even at a small external force. You may not. In addition, when the inclination angle of the cutout 52b is greater than 45, on the contrary, the elastic force of the cylindrical body 52a is so strong that the degree of elastic deformation of the cylindrical body 52a may be too small or not elastically deformed.

The packing density in which the polymer filter 52 is filled in the filter cylinder 51 of the solids remover 50 is 80 to 85% of the volume of the filter cylinder 51 in a natural state without external pressure, and thus the polymer filter 52 according to the flow rate. ) To ensure the fluidity of. The filling density of the polymer filter 52 set as described above forms a space between the polymer filter 52 and the polymer filter 52 which are formed while the polymer filter 52 has a close interval therebetween, and this space flows through the treated water. It is a flow path. In addition, a hollow flow path of the cylindrical body 52a forms a flow path through which the treated water flows.

Therefore, when the treated water in the first treatment tank 10 passes through the filter cylinder 51 of the solids remover 50, the oil component moves between the surface and the space of the polymer filter 52 made of a high density polymer polyethylene material. While coalescing. When the size of the coalesced oil droplets increases, it floats and flows toward the outlet 12, and the solids of the SS component are dropped by gravity to be removed from the bottom of the first treatment tank 10 through the lower portion of the filter cylinder 51.

At this time, since the polymer filter 52 is formed with a spiral cutout 52b in the longitudinal direction of the cylindrical body 52a, when the external force due to the flow pressure of the fluid or the adhesion between the adjacent polymer filters 52 is applied, The outer shape of the cylindrical body 52a repeats the elastic deformation and restoration as shown in FIGS. 4 and 5. This elastic deformation action facilitates the floating of the coalescing oil component while moving between the surface and the space of the cylindrical body 52a, and shakes off the solid attached to the surface of the cylindrical body 52a, thereby preventing the attachment of the solid. Minimized, it is more smooth to drop the solids to the filter cylinder 51 lower.

6 and 7, as shown in Figs. 6 and 7, the upper and lower parts of the filter cylinder 51 are closed by predetermined lengths by the cover parts 53 and 54, respectively. L) corresponds to one quarter of the total height, respectively.

Therefore, as shown in FIG. 6, in the state where the surface of the first treatment tank 10 is low, the polymer filter 52 is filled in the filter cylinder 51 at a volume ratio of 80 to 85%. Although the space portion is formed in the upper portion, the oil suspended in the space portion by the cover portion 53 of the upper side can be prevented from being discharged toward the outlet 12.

As shown in FIG. 7, when the number of treatments in the first treatment tank 10 increases and the water surface becomes high, the polymer filter 52 floats and a space portion is formed in the lower portion of the filter cylinder 51, but the lower cover portion The treated water not treated by 54 can be prevented from being discharged toward the discharge port 12.

8 and 9 are perspective views of the solids remover 50 viewed from the inflow side (front side) and the discharge side (back side), wherein the solids remover 50 is inclined with respect to the flow direction of the treated water. It is comprised by connecting 50A and 50B. Therefore, the treatment area can be increased by increasing the passage area of the treated water.

10 shows a through hole 51a of the filter cylinder 51. As shown in FIG. 10, the circumferential portion 51b of the through hole 51a is formed in a rounded shape, and the diameter thereof becomes narrower in the direction in which the treated water flows. It is composed. Therefore, the treated water passing through the filter cylinder 51 is easily guided to the through hole 51a and at the same time increases the flow rate when passing through the through hole 51a to smoothly flow the treated water.

Referring back to FIGS. 1 and 2, the second treatment tank 20 includes an inlet 21 connected to the outlet 12 of the first treatment tank 10 and an outlet 22 for discharging the treated water. It receives and stores the treated water from which the solid matter is removed from the first treatment tank 10 through the inlet 21.

In the second treatment tank 20, the oil component is separated from the treated water, and an oil / water separator 60 for separating the oil component from the treated water is provided at the inlet port 21.

The oil / water separator (60) includes a filter cylinder (61) made of a perforated plate having a plurality of through holes (61a) so that the treated water can pass therethrough. The filter cylinder (61) has a solids remover (50). As described above, the polymer filter 52 is filled with the same volume ratio.

The polymer filter 52 separates the oil component from the treated water passing through the filter cylinder 61 and floats it on the water surface. The oil / water separation function by the polymer filter 52 is the same as described above, and thus a detailed description thereof will be omitted.

FIG. 11 shows a through hole 61a formed in the filter cylinder 61 of the oil / water separator 60. As shown in the figure, the periphery of the through hole 61a is similar to the through hole 51a of the solids remover 50. As shown in FIG. 61b is formed in a round shape, and the diameter becomes narrower in the direction in which the treated water flows. Therefore, the treated water passing through the filter cylinder 61 is easily guided to the through hole 51a, while increasing the flow velocity when passing through the through hole 61a to smooth the flow of the treated water.

Referring back to FIGS. 1 and 2, the third treatment tank 40 is connected to the outlet 22 of the second treatment tank 20, and an inlet for introducing the treated water treated in the second treatment tank 20 ( 41) and a discharge port 42 for discharging the treated water, and stores the treated water introduced from the inlet 41.

The third treatment tank 40 is for finally removing the heavy metal and water-soluble oil from the treated water, non-woven filter 70 made of a non-woven fabric of geo-textile grade in the third treatment tank (40) Is installed. Therefore, the treated water flowing into the inlet 41 is discharged through the outlet 42 after the heavy metal and the water-soluble oil are removed by the nonwoven fabric filter 70.

The pretreatment tank 30 and the first to third treatment tanks 10, 20, and 40 having such a configuration gradually set the water level gradually in the order of flow of the treated water, and thus, from the pretreatment tank 30 to the third treatment tank 40. It is desirable to induce a non-powered flow of treated water.

In addition, the present invention is provided with an oil discharge blocking mechanism 80 in the second treatment tank (20). As shown in FIGS. 12 and 13, the oil discharge blocking device 80 is made of a material and weight that can float between the surface of the oil layer OR and the water surface WF which floats to the surface of the stored treated water. There is provided a floating body 81 to rise and fall according to. The floating body 81 is guided to the guide body 82, the guide body 82 guides the floating body 81, which rises and falls according to the level of the treated water, to the outlet 22 to the floating body 81 When the fall of the outlet 22 is to be closed.

Therefore, as shown in FIG. 13, since the floating body 81 is spaced apart from the outlet 22 in the state where the second treatment tank 20 has a high water level, the treated water may be discharged by opening the outlet 22. In addition, when the water level of the second treatment tank 20 is gradually lowered, the floating body 81 is guided to the guide body 82 and gradually lowers, so that the water level is lower than the outlet 22 as shown in FIG. When the floating body 81 closes the outlet 22 before the oil in the oil layer OR is discharged through the outlet 22, the oil can be prevented from being discharged to the outlet 22.

Although the present invention has been described only with respect to the embodiments described, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such modifications or changes will fall within the scope of the appended claims. .
