DETAILED DESCRIPTION
[0019] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.
[0020] It can be understood that, although the functional modules are divided in the device schematic diagram, and the logical sequence is shown in the flowchart, in some cases, the steps shown or described can be performed in a manner different from the module division in the device or the sequence in the flowchart. The terms "first", "second", etc. in the specification, claims or above-described drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.
[0021] Traditional water treatment processes are difficult to deeply degrade pharmaceuticals and personal care products, endocrine disruptors and persistent pollutants. At present, hydrogen peroxide oxidation, ozone oxidation, Fenton oxidation and other advanced oxidation processes are mainly used to generate hydroxyl radicals to degrade pollutants in water, but single advanced oxidation process technology is often limited by low hydroxyl radical yield and low organic matter mineralization. In order to enhance the removal of pollutants by oxidants, ultraviolet radiation is widely used in advanced oxidation process. At present, the ultraviolet reactor mainly uses fixed lamp tube combined with straight-through or baffle flow channel, but there is a "near-lamp area dose too high, far-lamp area dose insufficient" radial gradient, which restricts the removal efficiency of light-sensitive pollutants and microorganisms. At the same time, in the advanced oxidation system coupled with ozone, the traditional configuration will cause low ultraviolet-water contact efficiency due to uneven light field distribution, insufficient ultraviolet dose in short flow area, etc., which limits the yield of hydroxyl radicals, thereby reducing the efficiency of wastewater treatment.
[0022] Based on this, the embodiment of the present application discloses a spiral flow channel type ultraviolet light reactor based on LED lamp strip and a water treatment method. By opening the spiral extending first and second flow guide grooves on the base, the water flow path can be extended to make the pollutants contact with the oxidant more fully. The centrifugal force and secondary flow generated by spiral flow will form turbulent flow, enhance mass transfer and reduce boundary layer thickness to avoid reaction dead zone. In addition, by setting the first ultraviolet LED lamp strip on the inner wall of the first flow guide groove and the second ultraviolet LED lamp strip on the inner wall of the second flow guide groove, the optical path can be shortened to reduce the loss of light energy in water transmission, and high-density free radicals can be generated by exciting the oxidant, thereby effectively improving the efficiency of wastewater treatment and water quality purification.
[0023] In the first aspect, with reference to Figure 1 and Figure 2 , Figure 1 the structure schematic diagram of the spiral flow channel type ultraviolet light reactor based on LED lamp strip provided by the embodiment of the present application, Figure 2This is a partial schematic diagram of a spiral flow channel ultraviolet reactor based on LED light strips, provided in an embodiment of this application.
[0024] It is understood that the spiral flow channel ultraviolet reactor based on LED light strips includes a base 100, a first ultraviolet LED light strip, and a second ultraviolet LED light strip 310. The base 100 is provided with a first guide channel 200 and a second guide channel 300. The first guide channel 200 extends spirally toward the center of the base 100, and the second guide channel 300 extends spirally away from the center of the base 100. The first guide channel 200 and the second guide channel 300 are connected at the center of the base 100 for guiding the flow. The first guide channel 200 and the second guide channel 300 are connected at the center of the base 100. An inlet is provided on one side of the outer wall of the base 100, and an outlet is provided on the other side of the outer wall of the base 100. The first guide channel 200 is connected to the inlet, and the second guide channel 300 is connected to the outlet. The water to be treated enters the first guide channel 200 through the inlet. Since the first guide channel 200 and the second guide channel 300 are connected at the center of the base 100, the water to be treated will switch from the first guide channel 200 to the second guide channel 300 at the center of the base 100, and then flow out from the outlet. A first ultraviolet LED light strip is set on the inner wall of the first guide channel 200, and a second ultraviolet LED light strip 310 is set on the inner wall of the second guide channel 300. By setting the first ultraviolet LED light strip on the inner wall of the first guide channel 200 and the second ultraviolet LED light strip 310 on the inner wall of the second guide channel 300, the optical path can be shortened and the loss of light energy in the water body transmission can be reduced. In addition, since the first guide channel 200 and the second guide channel 300 are spiral-shaped, they can effectively enhance the radial mixing of the fluid and generate disturbance, thereby increasing the probability of collision between microorganisms / pollutants and ultraviolet photons and free radicals, and strengthening the sterilization and pollutant degradation kinetics. In the advanced oxidation process technology, the water to be treated enters the first guide tank 200 through the inlet along with gaseous ozone or liquid hydrogen peroxide. The ultraviolet light emitted by the first ultraviolet LED lamp reacts with the gaseous ozone to form ultraviolet ozone catalysis and with the liquid hydrogen peroxide to form ultraviolet hydrogen peroxide, effectively increasing the yield of free radicals in the water to be treated.
[0025] It should be noted that the water inlet includes a first water inlet 110 and a second water inlet 120, and the first water inlet 110 and the second water inlet 120 are connected with the first flow guide groove 200 to form a Y-shaped structure, wherein the first water inlet 110 can be connected with the input pipeline of the water to be treated, so that the water to be treated enters the first flow guide groove 200 through the first water inlet 110, and the power line of the first ultraviolet LED lamp strip can enter the first flow guide groove 200 through the second water inlet 120 to provide the power required for the working of the first ultraviolet LED lamp strip. The water outlet includes a first water outlet 130 and a second water outlet 140, and the first water outlet 130 and the second water outlet 140 are connected with the second flow guide groove 300 to form a Y-shaped structure, wherein the first water outlet 130 can be connected with the output pipeline of the water to be treated, so that the water to be treated flows out of the second flow guide groove 300 through the first water outlet 130, and the power line of the second ultraviolet LED lamp strip can enter and exit the second flow guide groove 300 through the second water outlet 140 to provide the power required for the working of the second ultraviolet LED lamp strip.
[0026] It can be understood that the first flow guide groove 200 includes a first side wall and a second side wall, and the first side wall and the second side wall are oppositely provided with a first dovetail clamping groove, and the first ultraviolet LED lamp strip is arranged in the first dovetail clamping groove, and the light emitting end of the first ultraviolet LED lamp strip faces the opening of the first dovetail clamping groove. By arranging the first ultraviolet LED lamp strip on both sides of the first flow guide groove 200, the light emitting surface faces the center of the flow guide groove, the residence time of the pollutants is prolonged by using the low flow rate area on the inner side of the spiral, and the light shielding effect is reduced. The second flow guide groove 300 includes a third side wall and a fourth side wall, and the third side wall and the fourth side wall are oppositely provided with a second dovetail clamping groove, and the second ultraviolet LED lamp strip 310 is arranged in the second dovetail clamping groove, and the light emitting end of the second ultraviolet LED lamp strip 310 faces the opening of the second dovetail clamping groove. By arranging the second ultraviolet LED lamp strip 310 on both sides of the second flow guide groove 300, the light emitting surface faces the center of the flow guide groove, the residence time of the pollutants is prolonged by using the low flow rate area on the inner side of the spiral, and the light shielding effect is reduced.
[0027] Specifically, as the time of water treatment increases, the concentration of pollutants in the water to be treated will continue to decrease, the concentration of pollutants in the water to be treated is the highest when the water to be treated just enters the reactor, and the concentration of pollutants decreases after a period of water treatment, in addition, if the concentration of pollutants in the water to be treated is low, the ultraviolet light can cause the chlorine ions or bromide ions in the water to be over-oxidized, generating harmful by-products such as excessive chlorine consumption or bromate. Therefore, the first ultraviolet LED lamp strip can be divided into a first part and a second part, and the second ultraviolet LED lamp strip 310 can be divided into a third part and a fourth part, wherein the first part is close to the water inlet, the second part is close to the connection between the first flow guide groove 200 and the second flow guide groove 300, the third part is close to the connection between the first flow guide groove 200 and the second flow guide groove 300, and the fourth part is close to the water outlet. By adjusting the density of the lamp beads of the first part, the second part, the third part and the fourth part, the intensity of ultraviolet light at each location can be changed. For example, after the water to be treated enters the LED lamp strip-based spiral flow channel type ultraviolet light reactor from the water inlet, it will pass through the first part, the second part, the third part and the fourth part in turn, that is, the density of the lamp beads of the first part, the second part, the third part and the fourth part can be adjusted so that the density of the lamp beads of the first part is greater than that of the second part, and the density of the lamp beads of the third part is greater than that of the fourth part.
[0028] Specifically, the ratio of the density of the lamp beads of the first part to the density of the lamp beads of the second part is a first ratio, the density of the lamp beads of the second part is equal to the density of the lamp beads of the third part, and the ratio of the density of the lamp beads of the third part to the density of the lamp beads of the fourth part is a second ratio, wherein the first ratio is equal to the second ratio and the density of the lamp beads of the second part is equal to the density of the lamp beads of the third part. For example, the water flow path formed by the first flow guide groove 200 and the second flow guide groove 300 is divided into an inlet section, a middle section and an outlet section, wherein the water flow path lengths of the inlet section, the middle section and the outlet section are equal, the first part of the first ultraviolet LED lamp strip is located in the inlet section, the second part of the first ultraviolet LED lamp strip and the third part of the second ultraviolet LED lamp strip 310 are located in the middle section, and the fourth part of the second ultraviolet LED lamp strip 310 is located in the outlet section, if the first ratio and the second ratio are 0.5, and the density of the lamp beads of the first part is 0.4mm, then the density of the lamp beads of the second part and the third part is 0.8mm, and the density of the lamp beads of the fourth part is 1.6mm. In addition, the density of the lamp beads of the first part, the density of the lamp beads of the second part, the density of the lamp beads of the third part and the density of the lamp beads of the fourth part can be adjusted according to the length of the first ultraviolet LED lamp strip and the second ultraviolet LED lamp strip.
[0029] By setting high-density UV LED lamp beads in the inlet section, the DNA / RNA structure of microorganisms can be quickly destroyed, and a large number of active free radicals can be generated to react with the molecular structure of refractory organic matter by the photocatalyst. In the middle section, the concentration of pollutants is reduced, and at this time, the medium lamp bead density can be used to maintain the free radical concentration required for chain reaction, to ensure that the oxidation process continues and stabilizes. And it can avoid unnecessary energy consumption caused by high-density lighting throughout the process. In the outlet section, the main pollutants have been basically removed, and at this time, if too strong ultraviolet light is still applied, it may cause the chlorine ion or bromide ion in the water to be over-oxidized, generating harmful by-products such as excessive chlorine consumption or bromate. By using a lower lamp bead density, the final disinfection effect is ensured, the risk of bromate generation is reduced, and the biological safety is improved.
[0030] It should be noted that the outer wall of the first flow guide groove 200 and / or the second flow guide groove 300 is provided with a sampling interface 400, which can be externally connected to an online turbidity, UVT254, ORP, pH, and dissolved ozone probe.
[0031] It can be understood that the spiral flow channel type ultraviolet light reactor based on the LED lamp strip further includes a mixing device, the mixing device is installed on the first water inlet 110, and the mixing device is used to mix the water to be treated and the oxidant. The treated sewage and the oxidant are mixed by the mixing device and then enter the first flow guide groove 200 from the first water inlet 110. The mixing device is an online static mixer or a Venturi jet, and the oxidant is ozone or liquid hydrogen peroxide. When the oxidant is gaseous ozone, ultraviolet ozone catalysis is formed after being irradiated by the ultraviolet light emitted by the first ultraviolet LED lamp. When the oxidant is liquid hydrogen peroxide, ultraviolet hydrogen peroxide is formed after being irradiated by the ultraviolet light emitted by the first ultraviolet LED lamp. In addition, the oxidant can also be liquid chlorine, hypochlorite, peroxymonosulfate, peroxydisulfate, and peroxyacetic acid.
[0032] It can be understood that the bottom of the base 100 is provided with a support member for supporting the bottom disc, and the top of the base 100 is provided with a mounting groove 150 corresponding to the position of the support member. In some embodiments, a plurality of spiral flow channel type ultraviolet light reactors based on the LED lamp strip can be stacked to form a reaction tower. For example, the first spiral flow channel type ultraviolet light reactor based on the LED lamp strip includes a first base 100, and the second spiral flow channel type ultraviolet light reactor based on the LED lamp strip includes a second base 100. The bottom of the first base 100 is provided with a support member for supporting the bottom disc. Since the top of the second base 100 is provided with a mounting groove 150 corresponding to the position of the support member, the support member of the first base 100 can be correspondingly mounted in the mounting groove 150 of the second base 100, so that the first spiral flow channel type ultraviolet light reactor based on the LED lamp strip and the second spiral flow channel type ultraviolet light reactor based on the LED lamp strip are connected to each other to form a reaction tower.
[0033] Specifically, in some embodiments, the base 100 comprises a first region and a second region, the first region is provided with the first flow guide groove 200 and the second flow guide groove 300, and the second region is provided with the support and the mounting groove 150, wherein the second region is located on both sides of the first region.
[0034] It should be noted that the second water inlet 120 is also provided with a microporous plate, when the ozone generator or the micro-nano bubble aerator is connected with the second water inlet 120, ozone micro-nano bubbles with an average diameter of 4.5-45 μm can be generated to improve the dissolution efficiency of pollutants in the water to be treated. In addition, when the microporous plate covers the second water inlet 120, a power supply through hole for penetrating the power line of the first UV LED light strip can also be provided on the base 100 near the second water inlet 120.
[0035] Specifically, in some embodiments, the top of the first flow guide groove 200 and the second flow guide groove 300 is also provided with a sealing plate, so that the first flow guide groove 200 and the second flow guide groove 300 form a flow guide cavity.
[0036] In a second aspect, referring to Figure 3 , Figure 3 The specific flow chart of the water treatment method provided by the embodiments of the present application is applied to the spiral flow channel type UV reactor based on the LED light strip in the above embodiments, and the water treatment method comprises but is not limited to the following steps: Step S100, obtaining the pollutant concentration of the water to be treated; Step S200, adjusting the first working power of the first UV LED light strip and the second working power of the second UV LED light strip according to the pollutant concentration.
[0037] It can be understood that for different pollutant concentrations, different intensities of ultraviolet rays can be used to irradiate the water to be treated, for example, in the case of high pollutant concentration, the first working power of the first UV LED light strip and the second working power of the second UV LED light strip can be adjusted to produce sufficient free radicals for rapid oxidation; in the case of low pollutant concentration, the first working power of the first UV LED light strip and the second working power of the second UV LED light strip can be adjusted to reduce energy consumption, prolong the service life of the light strip, and realize precise matching of light dose and pollution load while ensuring treatment effect.
[0038] It should be noted that in some embodiments, the LED lamp strip based spiral flow channel type ultraviolet light reactor further comprises a water flow regulator for adjusting the water inflow rate. For different pollutant concentrations, the water treatment effect can be improved in the case of higher pollutant concentration and the water treatment efficiency can be improved in the case of lower pollutant concentration by adjusting the water inflow rate. For example, in the case of higher pollutant concentration, the water inflow rate can be reduced to enable the water to be treated to fully react with the oxidant, and in the case of lower pollutant concentration, the water inflow rate can be increased to improve the water treatment efficiency.
