Description

Light-based water treatment device and water quality management system including the same

The present invention relates to a light-based water treatment device and a water quality management system including the same.

Although the domestic water supply rate is high at more than 95%, rural areas and remote areas still rely on groundwater for living water, agricultural water or livestock water due to the urban concentration phenomenon. Currently, various reports on groundwater contamination are being submitted at home and abroad. Typically, 204 confirmed patients have occurred due to secondary contamination of vegetables by groundwater contaminated with E. coli (O157), of which 3 There are fatal accidents (US FDA, 2010) and 8922 patients and 10 deaths (European Food Safety Administration (ECDC) report, 2007) due to groundwater contaminated with Salmonella bacteria. In particular, in the case of secondary contamination of crops by contaminated groundwater, the problem is serious in that there is a risk of regional expansion (Natvig et al,. Appl. Environ. Microbiol. 68, 2737-2744, 2002). In addition to typical bacteria such as E. coli, Salmonella spp, S. aureus and bacillus cereus, recently, cases of contamination by various strains of bacteria including superbacteria have also been reported. (US FDA. 2017). Nevertheless, social awareness of groundwater contamination is lacking, and awareness of the problems and seriousness of contaminated groundwater, especially even in agricultural and livestock facilities, is lacking.

In addition, water purification facilities are also contaminated due to various causes, such as the Incheon tap water larvae pollution incident (2020) and the Nakdong River phenol pollution incident (1991), and it is difficult to ensure its safety.

On the other hand, recently, due to abnormal climates such as global warming, drinking water is a problem in remote areas, rural areas, fishing villages and some small towns. It is emerging as a representative survival task for the future.

In order to solve the problem of contamination of groundwater and water supply as described above, and to secure stable and safe quality water, various methods through water treatment are being used for water purification. Representatively, a method using a filter, a method through chemical treatment , a method using ozone and a method using a photocatalyst.

The method of using a filter is a water treatment technology by adsorbing pollutants on the filter surface using physical and/or electrical characteristics with respect to causative bacteria and chemical substances in polluted water. As the adsorbing material, zeolite or activated carbon is widely used, but zeolite or activated carbon has a problem of self-contamination because larvae can breed therein.

The method through chemical treatment is a method of water treatment using chlorine, etc., and is widely used in water facilities and swimming pools. However, there is a problem of causing vomiting or headache due to the drug, and there is a problem that the water contaminated by some larvae cannot be purified.

The method using ozone is a water treatment technology that induces bacterial death by using ozone generated through plasma treatment using laser or high voltage. Ozone, a type of active oxygen, has the advantage of having a high sterilization effect due to its high active energy, but expensive equipment and professional personnel are required to generate plasma, and the generated ozone causes vomiting and headache, and its lifespan Since it lasts from several hours to several days in the atmosphere, there is a problem in that the diffusion range is very wide.

In addition, the method of using a photocatalyst mainly utilizes an inorganic photocatalyst, and is a water treatment method that uses the activation energy of the inorganic photocatalyst to kill bacteria and decompose harmful chemicals. However, in the case of using the inorganic photocatalyst as described above, since most of the light absorption region of the material is in the ultraviolet region, sunlight cannot be utilized. There is a risk of contamination, and there is a problem in that it is difficult to recover the photocatalyst.

Therefore, there is no self-contamination and secondary pollution, it is reusable, it is possible to treat microorganisms such as chemicals as well as bacteria, and it is easy to expand and operate, and an economical water treatment device is required in terms of facilities and operation. .

In the present invention, the optical functional beads 70 filled in the flow path absorb light energy to generate active oxygen, and the generated active oxygen can decompose chemicals and harmful microorganisms present in the raw water to treat raw water.

The first flow path 40 is an empty space formed inside the housing 10 , and serves to receive raw water introduced through the inlet 20 until it is discharged to the outlet 30 . The raw water flows from the inlet to the outlet through the first flow path 40 , and at this time, the raw water is water-treated by the photofunctional beads 70 .

The inlet 20 serves to supply raw water containing microorganisms or harmful chemicals into the housing 10 . Accordingly, the inlet 20 may have a structure connected to a water collecting tank in which raw water is stored through a pipe or a hose.

The inlet 20 is formed at the end of the first flow path formed inside the housing, and may be connected by a fastener such as a flange or formed by a method such as welding.

A first flow path 40 through which raw water supplied through the inlet 20 can flow is formed in the housing 10 .

The housing 10 is preferably made of a material exhibiting light transmittance, and may be made of, for example, a photofunctional film or a photosensitizer alloy film. The photofunctional film may refer to a film in which a photosensitizer and a photocurable polymer resin are mixed. The photocurable polymer resin may include at least one selected from the group consisting of silicone, latex, polyurethane, and polyethylene terephthalate. The photosensitizer alloy film may refer to a film in which a photosensitizer is ester-bonded to a metal surface. The metal may include at least one selected from the group consisting of stainless steel, aluminum, magnesium, tin, titanium, tungsten, and nickel.

The photo-functional bead 70 may have an antibacterial action or a chemical decomposition action by a light source. Specifically, the photo-functional beads may be a material that generates active oxygen when irradiated with light, thereby killing microorganisms or decomposing chemicals.

The photofunctional bead 70 may include a polymer support and a photosensitizer.

The polymer support is polydimethylsiloxane, polyurethane, polyethylene terephthalate, polytetrafluoroethylene, polymethyl methacrylate (Poly (methyl methacrylate)), 2-hydroxy It may be at least one selected from the group consisting of hydroxyethyl methacrylate (poly(2-hydroxyethyl methacrylate)), poly(N-isopropyl acrylamide), chitosan hydrogel, and alginic acid hydrogel.

The polymer support serves as a support and a binder of the photofunctional bead, and may impart rigidity to the photofunctional bead.

The filling rate can be appropriately set in consideration of the contamination level of the raw water, the flow rate and flow rate of the incoming raw water, but when it exceeds the above range, there is a problem that the flow rate is too slow, and below the above range, there is a problem that the water treatment efficiency is lowered. .

In addition, the photo-functional bead 70 may have a protrusion formed on the surface. As described above, the photo-functional beads formed with protrusions on the surface provide a large surface area, thereby improving water treatment efficiency, and even when the flow rate and flow rate of raw water increase, the photo-functional beads formed on the surface engage the photo-functional beads with each other. It is possible to prevent the phenomenon that the photofunctional beads are tilted in the flow direction.

After mixing and stirring the photosensitive agent, the polymer support, the initiator and the surfactant, the photofunctional beads with protrusions formed on the surface as described above can be prepared by dropping the mixed solution into a liquid medium under light irradiation conditions.

In this case, a driving unit for rotating the support member 50 when raw water flows in the first flow path may be additionally included.

By rotating the support member 50, the contact area and contact time between the raw water and the optically functional bead 70 can be increased. In particular, when the flow rate of the raw water, the flow rate of the raw water, or the rotational speed of the central axis increases, the contact area and contact time between the raw water and the photofunctional bead increases, so that the water treatment efficiency can be improved.

In addition, as the support member 50 has a blade 60, the effect of increasing the contact area and contact time between the raw water and the photofunctional bead, as well as the photofunctional bead by the raw water is focused in the flow direction of the raw water. , it is possible to prevent a decrease in water treatment efficiency. In addition, by generating a vortex in the raw water, it can have the effect of increasing the water treatment efficiency.

In addition, due to the partition wall 80, the first flow path may be bent at a predetermined angle by three adjacent second flow paths along the flow direction, for example, the angle may be a right angle, in this case, the flow direction Accordingly, three adjacent second flow paths may have a 'c' shape.

When the partition wall 80 is formed as described above, it is possible to increase the water treatment time of the raw water inside the water treatment device, and it is possible to increase the water treatment efficiency by forming a vortex in the raw water.

The location and size of the partition wall are not limited, but may have, for example, a shape as shown in FIG. 2 .

Specifically, the housing has a first surface 81a forming a flow path and a second surface 81b facing the first surface, and in this case, the first partition wall extends from the first surface to the second surface side of the housing. 80a and a second partition wall 80b extending from the second surface to the first surface side may be included, and a plurality of the first partition wall and the second partition wall may be disposed.

In this case, since the first barrier rib does not contact the second surface and the second barrier rib does not contact the first surface, a plurality of second flow paths adjacent along the flow direction may be formed.

In addition, in the example shown in FIG. 2, only a form in which the partition wall 80 is added to the side surface of the housing is illustrated, but it is assumed that the partition wall is formed from the side surface of the housing as well as the upper or lower portion of the housing, or a combination thereof. It can also be easily derived.

In addition, the barrier rib 80 is preferably made of a material exhibiting light transmittance, and may be formed of, for example, a photofunctional film or a photosensitizer alloy film. The photofunctional film may refer to a film in which a photosensitizer and a photocurable polymer resin are mixed. The photocurable polymer resin may include at least one selected from the group consisting of silicone, latex, polyurethane, and polyethylene terephthalate. The photosensitizer alloy film may refer to a film in which a photosensitizer is ester-bonded to a metal surface. The metal may include at least one selected from the group consisting of stainless steel, aluminum, magnesium, tin, titanium, tungsten, and nickel.

In this case, the protrusion member 90 may form an acute angle with respect to the inner circumferential surface 82 of the first flow path 40 and the flow direction of the raw water. For example, the protrusion member may be formed at an angle of 0 to 85°, 10 to 70°, 20 to 60°, or 30 to 50° with the inner peripheral surface 82 with respect to the flow direction of raw water.

When the protrusion member 90 is formed as described above, a vortex is generated in the raw water to increase the contact area and time between the photofunctional beads and the raw water, and it is possible to increase the water treatment efficiency.

In the water treatment device 1 of the present invention, a light source irradiation device 95 may be provided inside the housing 10 . Since the photo-functional bead 70 can generate active oxygen in the sunlight range, it is possible to water treatment raw water using sunlight, but when sunlight is not available or inside the housing to increase water treatment efficiency A light source irradiation device 95 may be provided.

Preparation Example 1

10 g of ethanol as a solvent, 10 g of polyethylene terephthalate (PET) as a polymer support, and 10-Hydroxy pheophytin-A, 7 mM as a photosensitizer were stirred for 1 hour at 25° C. in the dark. To the stirred solution, 0.3 g of TPO (2,4,6-trimethylbenzoyldiphenyl phosphine oxide) and 0.2 g of a surfactant (F-477, 10%) were added as a photoinitiator, followed by stirring at 25° C. in the dark for 1 hour. Thereafter, it was placed in a vacuum oven and left for 2 hours at 45° C. in a dark room, after which the solvent was removed. The above solution was placed in a mold and irradiated with UV light to prepare photosensitive beads. The prepared photosensitive beads had an average diameter of 13 mm and a spherical shape.

Preparation 2

Polyethylene terephthalate (PET) 10g as a polymer support, 10-Hydroxy pheophytin-A, 7mM as a photosensitizer, 0.3g TPO (2,4,6-trimethylbenzoyldiphenyl phosphine oxide) as a photoinitiator, and a surfactant (F-477, 10%) After adding 0.2 g, the mixture was stirred for 1 hour at 25° C. in a dark room. Then, the solution was irradiated with UV and dropped into the aqueous solution with a dropper to prepare photosensitive beads having an average diameter of 13 mm and protrusions formed on the surface.

Experimental example

6 and 7, using Comparative Example 1, Example 7 without light irradiation, and Example 7 with light irradiation with respect to E. coli (FIG. 6) and Staphylococcus (FIG. 7), the flow rate and light amount were adjusted and the result of measuring the viable count is shown.

It can be seen that the slower the flow rate and the stronger the light irradiation amount, the lower the survival rate of E. coli and staphylococcus. Comparative Example 1 without photofunctional beads and support member and Example 7 without light irradiation are of E. coli and Staphylococcus aureus. The killing effect was insignificant.

In addition, E. coli, Staphylococcus aureus, MRSA (Methicillin-Resistant Staphylococcus (MRSA) Aureus), VRSA (Vancomycin-Resistant Staphylococcus Aureus), O-157 (atcc 700927), VRE (vancomycin-Resistance Enterococcus), PA (Pantoea agglomerans), PF (Pseudomonas fluorescens), PC (Pectobacterium carotovorum) and bisphenol A Viable count was measured. The results are shown in Table 2 below.

As shown in Table 2, in the case of Examples 1 to 9, it can be seen that the reduction of microorganisms and chemicals was significantly reduced compared to Comparative Examples 1 to 6.

In particular, in Examples 3 to 9 using Preparation Examples 2 and 3, the number of survivors was much less, which in the case of Preparation Example 1, despite the low flow rate, the photosensitive beads were tilted backward according to the flow of raw water. This is due to the decrease in water treatment efficiency.

In addition, it can be seen that the water treatment efficiency of Comparative Examples 3 to 6 in which the central axis is not formed, the blade is not formed on the outer surface, or the protruding wall is not formed.
