Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to a laboratory organic wastewater degradation device. Background Art

[0002] In postgraduate entrance examination and testing laboratories in universities and research institutes, the organic wastewater generated every day needs to be regularly collected by full-time personnel and equipment and centrally treated. According to statistics, this type of wastewater is generally collected and treated once every two weeks or longer. However, some highly hazardous organic wastewater needs to be treated as soon as possible to avoid causing harm during the process of stacking and storing.

[0003] After searching for the Chinese patent with the publication number CN118145851A, a laboratory wastewater treatment device and method are disclosed. The laboratory wastewater treatment device includes a device body, universal wheels provided at the four corners of the bottom of the device body, a wastewater treatment component provided in the inner cavity of the device body for filtering wastewater, a cleaning component provided on the wastewater treatment component, and a linkage component provided on the cleaning component. This laboratory wastewater treatment device can perform primary filtration treatment on large impurity particles in the wastewater through a primary filter plate, reduce the load of subsequent treatment, protect the normal operation of the device, and then effectively degrade the organic waste in the wastewater by adding an oxidant to the wastewater, converting the organic waste into inorganic products or substances that are easier to treat, reducing the concentration of organic matter in the wastewater, reducing environmental pollution, and making the wastewater easier to be treated or discharged subsequently.

[0004] However, the existing technology has the following deficiencies:

[0005] In the existing technology, there is a method of mixing wastewater with ozone water and then treating the wastewater through ultraviolet light source catalysis. This method requires the wastewater and ozone water to come into contact with a nano-filter, using the nano-filter as the reaction substrate. However, when this technology is used, since the ultraviolet light source is set in the wastewater, some substances in the wastewater are likely to remain on the surface of the ultraviolet light source after the reaction, affecting the irradiation of the ultraviolet light source on the wastewater and ozone water. Secondly, the mixing between ozone water and wastewater is likely to be uneven, resulting in insufficient reaction between the two and affecting the degradation effect. Summary of the Invention

A plurality of elastic members are installed inside the sealing seat.

[0018] The present invention provides a laboratory organic wastewater degradation device through improvement. Compared with the prior art, it has the following improvements and advantages:

[0019] Firstly: Through the setting of the driving mechanism, when the wastewater and ozone water are mixed inside the filtering barrel, the driving motor can be started. The driving motor drives the first gear to rotate. The first gear meshes with the transmission gear ring for transmission. Thus, the nano-channel filter screen can be driven to rotate by the transmission gear ring. The rotation of the nano-channel filter screen can make the contact between the wastewater and ozone water and the nano-channel filter screen more sufficient, improving the reaction speed. The nano-channel filter screen drives the stirring blades to rotate. The rotation of the stirring blades can stir and mix the wastewater and ozone water inside the treatment barrel. At the same time, the rotation of the transmission gear ring can drive the second gear to rotate. The second gear drives the driving shaft to rotate. Since the driving shaft is threadedly connected to the transmission block, the rotation of the driving shaft will cause the transmission block to drive the movable sleeve to move back and forth on the ultraviolet light source. The movable sleeve moving back and forth on the ultraviolet light source can clean the surface of the ultraviolet light source, avoiding the situation that impurities in the wastewater adhere to the ultraviolet light source and affect the illumination of the ultraviolet light source.

[0020] Second: With the setting of the flushing mechanism in the present invention, when the movable sleeve moves downward, the movable sleeve drives the piston rod to move. The piston rod then drives the piston block to move downward inside the piston tube. Under the action of suction, the wastewater and ozone water at the middle position inside the treatment barrel are sucked into the inside of the piston tube through the water inlet hole. At the same time, due to the setting of the water outlet hole, the wastewater and ozone water below the treatment barrel are also sucked into the inside of the piston tube. However, since the inside of the water outlet hole gradually becomes smaller from the inside to the outside, the amount of wastewater and ozone water entering the piston tube through the water outlet hole is much less than that entering through the water inlet hole. As the movable sleeve moves upward, the piston block also moves upward inside the piston tube, thereby squeezing the wastewater and ozone water inside the piston tube. At this time, the wastewater and ozone water inside the piston tube will be discharged from the inside of the piston tube through the water outlet hole and the water inlet hole. Due to the shapes of the water inlet hole and the water outlet hole, the amount of wastewater and ozone water discharged from the piston tube through the water outlet hole is greater than that discharged through the water inlet hole, so that the wastewater and ozone water above the filter barrel can be transferred to the lower part inside the treatment barrel, further improving the contact between the wastewater and ozone water and the nano-channel filter screen, enhancing the mixing effect of the wastewater and ozone water, and further enhancing the reaction effect.

[0021] Third: With the setting of the sealing plate in the present invention, when the wastewater inside the filter barrel is sent into the treatment barrel through the wastewater delivery pipe, the wastewater squeezes the sealing plate, causing the sealing plate to move and leave the inside of the wastewater delivery pipe. At this time, the wastewater can enter the treatment barrel. The sealing plate drives the sealing block to move inside the water inlet seat, and at this time, the water inlet seat can be opened, and the ozone water inside the ozone generator can enter the treatment barrel through the water inlet seat, thus achieving the effect of automatically adding ozone water when discharging wastewater, and at the same time, the mixing ratio between the wastewater and ozone water can be adjusted.

[0022] Fourth: In the present invention, when the wastewater is drained, the pressure-sensitive switch activates the electric control valve, and then clear water can be sent into the filter barrel through the clear water inlet pipe. The clear water enters the inside of the clear water delivery pipe. Since the clear water delivery pipe is located inside the sealing sleeve, under the action of pressure, the clear water delivery pipe moves downward, so that the water spraying port on the clear water delivery pipe corresponds to the water spraying port on the sealing sleeve. At this time, the clear water inside the clear water delivery pipe can be sprayed into the filter barrel through the water spraying port, and the inside of the filter barrel can be cleaned at this time.

Detailed implementation manners

[0035] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] The present invention provides a laboratory organic wastewater degradation device through improvement. The technical solution of the present invention is as follows:

[0037] As Figures 1 to 9 shown, an embodiment of the present invention provides a laboratory organic wastewater degradation device, including a bottom plate 1, a filtering barrel 2 and a treatment barrel 3. The bottom plate 1 is a rectangular plate, and both the filtering barrel 2 and the treatment barrel 3 are hollow cylindrical structures. The filtering barrel 2 is fixedly installed on one side of the top of the bottom plate 1, and the treatment barrel 3 is arranged on the other side of the top of the bottom plate 1. A base 11 is fixedly installed on the top of the bottom plate 1, and the treatment barrel 3 is installed inside the base 11. An ozone generator 4 is fixedly installed on the top of the treatment barrel 3. The ozone generator 4 is a hollow cylindrical structure, and the ozone generator 4 is communicated with the inside of the treatment barrel 3. A wastewater inlet pipe 5 communicating with the inside of the filtering barrel 2 is fixedly installed on the top of the filtering barrel 2, and the wastewater inlet pipe 5 is used to send wastewater into the inside of the filtering barrel 2. Two electrode blocks 6 are installed inside the ozone generator 4, and a tap water inlet pipe 7 is installed on the top of the ozone generator 4. The tap water inlet pipe 7 is used to send tap water into the inside of the ozone generator 4. The two electrode blocks 6 are respectively an anode and a cathode. After the electrode blocks 6 are powered on, the electrode blocks 6 can electrolyze water molecules to generate hydroxyl radicals and ozone with strong oxidizing properties at low voltage, that is, turn tap water into ozone water. A nanochannel filter screen 8 is arranged inside the treatment barrel 3. The nanochannel filter screen 8 is a nanotube synthesized by electrochemical anodic oxidation treatment on a titanium mesh with TiO2 (or doped with other elements). Two ultraviolet light sources 9 are installed at the middle position inside the filtering barrel 2. When the wastewater and the ozone water enter the inside of the treatment barrel 3 together, the wastewater and the ozone water are mixed. The ultraviolet light sources 9 are started. Under the irradiation of the ultraviolet light sources 9, the wastewater and the ozone water flow through the surface of the nanochannel filter screen 8, and the harmful molecules in the wastewater will be degraded into CO2, H2O or other low-risk small molecules. A drain pipe 10 is fixedly installed at the bottom of the treatment barrel 3, and a valve is installed on the drain pipe 10. When the wastewater is treated, it can be discharged through the drain pipe 10 from the inside of the filtering barrel 2;

[0038] The interior of the treatment barrel 3 is provided with a driving mechanism and a flushing mechanism. The driving mechanism includes a driving motor 12, a first gear 13, a transmission gear ring 14, a second gear 15, a driving shaft 16 and a transmission block 18. The driving motor 12 is fixedly installed on the top of the bottom plate 1. The first gear 13 is fixedly installed on the output end of the driving motor 12, and the first gear 13 is located inside the treatment barrel 3 and the base 11. The transmission gear ring 14 is fixedly installed on the bottom wall surface of the nano-channel filter screen 8. The transmission gear ring 14 is of an annular structure, and the transmission gear ring 14 meshes and drives with the first gear 13. The second gear 15 is embedded and movably installed inside the treatment barrel 3. The second gear 15 is of a circular structure, and the second gear 15 meshes and drives with the transmission gear ring 14. The driving shaft 16 is of a structure with a reciprocating lead screw. The driving shaft 16 is fixedly installed at the center of the top of the second gear 15. An activity sleeve 17 is sleeved on the ultraviolet light source 9. The activity sleeve 17 is of a hollow cylindrical structure, and the inner wall of the activity sleeve 17 fits against the side wall of the ultraviolet light source 9. The transmission block 18 is a block of a rectangular structure. The transmission block 18 is fixedly installed on the two activity sleeves 17. The two activity sleeves 17 are fixedly connected through the transmission block 18. The driving shaft 16 penetrates upward through the upper and lower wall surfaces on one side of the transmission block 18 and is threadedly connected to the transmission block 18. A plurality of stirring blades 24 are fixedly installed above the inner wall of the nano-channel filter screen 8. The stirring blades 24 are blocks of a rectangular structure, and the top of the stirring blades 24 is a slope. Through the setting of the driving mechanism, when the wastewater and the ozone water are mixed inside the filtering barrel 2, the driving motor 12 can be started. The driving motor 12 drives the first gear 13 to rotate. The first gear 13 meshes and drives with the transmission gear ring 14. Then, the nano-channel filter screen 8 can be driven to rotate through the transmission gear ring 14. The rotation of the nano-channel filter screen 8 can make the contact between the wastewater and the ozone water and the nano-channel filter screen 8 more sufficient, improving the reaction speed. The nano-channel filter screen 8 drives the stirring blades 24 to rotate. The rotation of the stirring blades 24 can stir and mix the wastewater and the ozone water inside the treatment barrel 3. At the same time, the rotation of the transmission gear ring 14 can drive the second gear 15 to rotate. The second gear 15 drives the driving shaft 16 to rotate. Since the driving shaft 16 is threadedly connected to the transmission block 18, the rotation of the driving shaft 16 will cause the transmission block 18 to drive the activity sleeve 17 to move back and forth on the ultraviolet light source 9. The movement of the activity sleeve 17 back and forth on the ultraviolet light source 9 can clean the surface of the ultraviolet light source 9, avoiding the situation that impurities in the wastewater adhere to the ultraviolet light source 9 and affect the illumination of the ultraviolet light source 9.

[0039] The flushing mechanism includes a piston tube 19, a piston block 20 and a piston rod 21. The piston tube 19 is of a hollow cylindrical structure and is fixedly installed below the interior of the treatment barrel 3. The piston block 20 is a circular block with the same size as the interior of the piston tube 19, and the piston block 20 is movably installed above the interior of the piston tube 19. The piston rod 21 is of a "T" shape and is fixedly installed on the top of the piston block 20, and the piston rod 21 penetrates through the top wall surface of the piston tube 19. The top of the piston rod 21 is fixedly connected above the two movable sleeves 17. A plurality of water inlet holes 22 are formed in the top wall surface of the piston tube 19. The water inlet holes 22 are circular holes that gradually become smaller from top to bottom. A set of water outlet holes 23 are formed on both the upper and lower sides of the side wall of the piston tube 19. The water outlet holes 23 are circular holes that gradually become smaller from inside to outside. Through the setting of the flushing mechanism, when the movable sleeve 17 moves downward, the movable sleeve 17 will drive the piston rod 21 to move, and the piston rod 21 will further drive the piston block 20 to move downward inside the piston tube 19. Under the action of suction, the wastewater and ozone water at the middle position inside the treatment barrel 3 will be sucked into the interior of the piston tube 19 through the water inlet holes 22. At the same time, due to the setting of the water outlet holes 23, the wastewater and ozone water below the interior of the treatment barrel 3 will also be sucked into the interior of the piston tube 19. However, since the interior of the water outlet holes 23 gradually becomes smaller from inside to outside, the amount of wastewater and ozone water entering the interior of the piston tube 19 through the water outlet holes 23 is much smaller than the amount entering through the water inlet holes 22. As the movable sleeve 17 moves upward, the piston block 20 will also move upward inside the piston tube 19, thereby squeezing the wastewater and ozone water inside the piston tube 19. At this time, the wastewater and ozone water inside the piston tube 19 will be discharged from the interior of the piston tube 19 through the water outlet holes 23 and the water inlet holes 22. Due to the shapes of the water inlet holes 22 and the water outlet holes 23, the amount of wastewater and ozone water discharged from the interior of the piston tube 19 through the water outlet holes 23 is greater than the amount discharged through the water inlet holes 22, so that the wastewater and ozone water above the interior of the filter barrel 2 can be transferred to below the interior of the treatment barrel 3, thereby further improving the contact between the wastewater and ozone water and the nano-channel filter screen 8 and enhancing the mixing effect of the wastewater and ozone water, and further enhancing the reaction effect.

[0040] A water pump 25 is fixedly installed on the bottom plate 1. A water suction pipe 26 is fixedly installed on the input end of the water pump 25. The water suction pipe 26 is communicated with the inside of the filter barrel 2. A waste water delivery pipe 27 is fixedly installed on the output end of the water pump 25. The waste water delivery pipe 27 is communicated with the upper part inside the treatment barrel 3. The waste water inside the filter barrel 2 is sent into the inside of the treatment barrel 3 through the water pump 25 after being filtered. An inlet seat 28 is fixedly installed above the inside of the treatment barrel 3. The inlet seat 28 is of a "T" - shaped structure. The inlet seat 28 communicates the inside of the treatment barrel 3 and the ozone generator 4. A sealing block 30 is movably installed inside the inlet seat 28. The sealing block 30 is of a hollow rectangular structure. The sealing block 30 seals the inside of the inlet seat 28. A sealing plate 31 is fixedly installed on one side of the inside of the waste water delivery pipe 27 close to the inlet seat 28. The sealing plate 31 is a circular plate. The sealing plate 31 seals the inside of the waste water delivery pipe 27. The sealing plate 31 is fixedly connected to the sealing block 30. A movable rod 32 is fixedly installed on the sealing block 30. The movable rod 32 penetrates the side wall of the inlet seat 28. A first spring 33 is sleeved on the movable rod 32. Through the setting of the sealing plate 31, when the waste water inside the filter barrel 2 is sent into the inside of the treatment barrel 3 through the waste water delivery pipe 27, the waste water will squeeze the sealing plate 31, causing the sealing plate 31 to move and leave the inside of the waste water delivery pipe 27. At this time, the waste water can enter the inside of the treatment barrel 3. The sealing plate 31 drives the sealing block 30 to move inside the inlet seat 28. At this time, the inlet seat 28 can be opened, and the ozone water inside the ozone generator 4 can enter the inside of the treatment barrel 3 through the inlet seat 28, thus achieving the effect of automatically adding ozone water when discharging waste water;

[0041] Above the inside of the treatment barrel 3, there is a mixing chamber 29 located below the inlet seat 28. The mixing chamber 29 is communicated with the inside of the inlet seat 28. The mixing chamber 29 is of a hollow cylindrical structure. An inlet port 34 is opened at the top of the mixing chamber 29 corresponding to the position of the waste water delivery pipe 27. The inlet port 34 is a circular hole. A circular hole is also opened at the middle position of the bottom of the mixing chamber 29. A mixing blade 35 is movably installed in the middle of the inside of the mixing chamber 29. A fixing rod 36 is fixedly installed above the inner wall of the nano - channel filter screen 8. The fixing rod 36 is fixedly connected to the mixing blade 35. When the nano - channel filter screen 8 rotates, the nano - channel filter screen 8 can drive the mixing blade 35 to rotate through the fixing rod 36. The waste water discharged from the waste water delivery pipe 27 will enter the inside of the mixing chamber 29 through the inlet port 34. At the same time, the ozone water inside the inlet seat 28 will also enter the inside of the mixing chamber 29. At this time, the rotation of the mixing blade 35 can preliminarily mix the waste water and the ozone water, and then it can enter the inside of the treatment barrel 3 through the circular hole at the bottom of the mixing chamber 29. A diversion seat 37 is fixedly installed below the mixing chamber 29. The diversion seat 37 is of a frustum - shaped structure that gradually becomes larger from top to bottom. The pre - mixed waste water and ozone water discharged from the mixing chamber 29 will flow onto the surface of the nano - channel filter screen 8 after being diverted by the diversion seat 37.

[0042] An adjustment groove 38 is provided inside the sealing block 30. An adjustment block 39 is movably installed inside the adjustment groove 38. The adjustment block 39 is a "T"-shaped block. An electric push rod 40 is fixedly installed inside the adjustment groove 38. The output end of the electric push rod 40 is fixedly connected to the adjustment block 39. When the electric push rod 40 is started, the electric push rod 40 can drive the adjustment block 39 to move inside the adjustment groove 38, thereby adjusting the internal size of the sealing block 30, so that the amount of ozone water entering the mixing chamber 29 through the sealing block 30 changes, and then the mixing ratio between the wastewater and the ozone water can be adjusted.

[0043] A filtering mechanism is arranged inside the filtering barrel 2. The filtering mechanism includes a filtering seat 41, a filter plate 42, a mounting block 43, a reset rod 44 and a second spring 45. The filtering seat 41 is a hollow annular structure, and the top of the filtering seat 41 is inclined. The filter plate 42 is movably installed below the inside of the filtering seat 41. The wastewater entering the filtering barrel 2 will fall into the inside of the filtering seat 41 and then be filtered by the filter plate 42. The mounting block 43 is a rectangular block, and the mounting block 43 is fixedly installed on the inner wall of the filtering barrel 2. The reset rod 44 is a cylindrical structure, and the reset rod 44 is fixedly installed on the filtering seat 41, and the reset rod 44 penetrates through the upper and lower wall surfaces of the mounting block 43. The second spring 45 is sleeved on the reset rod 44. When the wastewater impacts the filter plate 42, the filter plate 42 will drive the filtering seat 41 to move downward, so that the reset rod 44 moves on the mounting block 43 and compresses the second spring 45. When the filtering is completed, the second spring 45 will release the elastic force to drive the filtering seat 41 and the filter plate 42 to reset, and then the filter plate 42 can be vibrated to shake out the impurities blocked inside the filter plate 42 to avoid blockage of the filter plate 42;

[0044] A pressing plate 46 is movably installed below the inside of the filtering barrel 2. The pressing plate 46 is a circular plate with the same size as the inside of the filtering barrel 2. An installation spring rod 47 is fixedly installed inside the filtering barrel 2. The installation spring rod 47 penetrates through the upper and lower wall surfaces of the pressing plate 46. The water extraction pipe 26 also penetrates through the upper and lower wall surfaces of the pressing plate 46. A rectangular opening communicating with the inside of the water extraction pipe 26 is provided below the side wall of the water extraction pipe 26. When the wastewater passes through the filtration, it will squeeze the pressing plate 46, causing the pressing plate 46 to move downward. When the pressing plate 46 moves to expose the opening below the water extraction pipe 26, the wastewater can be sent into the inside of the treatment barrel 3 through the water extraction pipe 26. A clean water inlet pipe 48 is installed at the top of the filtering barrel 2. The clean water inlet pipe 48 is communicated with the inside of the filtering barrel 2. The other end of the clean water inlet pipe 48 is connected to an external water source. An electric control valve 49 is installed on the clean water inlet pipe 48. A pressure sensing switch 50 is installed below the inside of the filtering barrel 2. The pressure sensing switch 50 is electrically connected to the electric control valve 49;

[0045] A sealing seat 51 is fixedly installed at the top of the filter barrel 2. The sealing seat 51 is of a hollow cylindrical structure. The bottom of the clear water inlet pipe 48 is located inside the sealing seat 51. A clear water delivery pipe 52 is movably installed below the inside of the sealing seat 51. The clear water delivery pipe 52 is a cylindrical pipe. A sealing sleeve 54 is fixedly installed on the top wall surface inside the filter barrel 2. The sealing sleeve 54 is a cylindrical pipe. The clear water delivery pipe 52 is located inside the sealing sleeve 54. Both the clear water delivery pipe 52 and the sealing sleeve 54 penetrate through the upper and lower wall surfaces of the filter plate 42. A vortex blade 53 is movably installed inside the clear water delivery pipe 52. A plurality of water spray nozzles 55 are provided on both the clear water delivery pipe 52 and the sealing sleeve 54, and the water spray nozzles 55 on the clear water delivery pipe 52 intersect with the positions of the water spray nozzles 55 on the sealing sleeve 54. A plurality of elastic members 56 are installed inside the sealing seat 51. The elastic members 56 are of a hollow structure. When wastewater enters the inside of the filter barrel 2, the downward movement of the pressing plate 46 will trigger the pressure-sensitive switch 50. When the wastewater is drained out, the pressure-sensitive switch 50 will activate the electric control valve 49, and then clear water can be sent into the inside of the filter barrel 2 through the clear water inlet pipe 48. The clear water enters the inside of the clear water delivery pipe 52. Since the clear water delivery pipe 52 is located inside the sealing sleeve 54, under the action of pressure, the clear water delivery pipe 52 will move downward, so that the water spray nozzles 55 on the clear water delivery pipe 52 correspond to the water spray nozzles 55 on the sealing sleeve 54. At this time, the clear water inside the clear water delivery pipe 52 can be sprayed into the inside of the filter barrel 2 through the water spray nozzles 55, and at this time, the inside of the filter barrel 2 can be cleaned. When not cleaning, the sealing sleeve 54 can seal the clear water delivery pipe 52 to prevent wastewater from entering the inside of the clear water delivery pipe 52.

[0046] Specific implementation steps: When the wastewater and the ozone water enter the inside of the treatment barrel 3 together, the wastewater and the ozone water are mixed, and the ultraviolet light source 9 is started. Under the irradiation of the ultraviolet light source 9, the wastewater and the ozone water flow through the surface of the nano-channel filter screen 8, and the harmful molecules in the wastewater will be degraded into CO2, H2O or other low-risk small molecules. When the wastewater is treated, it can be discharged from the inside of the filter barrel 2 through the drain pipe 10.

[0047] Through the setting of the driving mechanism, when the wastewater and the ozone water are mixed inside the filter barrel 2, the driving motor 12 can be started. The driving motor 12 drives the first gear 13 to rotate. The first gear 13 and the transmission gear ring 14 are in meshing transmission. Furthermore, the nano-channel filter screen 8 can be driven to rotate by the transmission gear ring 14. The rotation of the nano-channel filter screen 8 can make the contact between the wastewater and the ozone water and the nano-channel filter screen 8 more sufficient, improving the reaction speed. The nano-channel filter screen 8 drives the stirring blade 24 to rotate. The rotation of the stirring blade 24 can stir and mix the wastewater and the ozone water inside the treatment barrel 3. At the same time, the rotation of the transmission gear ring 14 can drive the second gear 15 to rotate. The second gear 15 drives the drive shaft 16 to rotate. The drive shaft 16 is threadedly connected to the transmission block 18. The rotation of the drive shaft 16 will make the transmission block 18 drive the movable sleeve 17 to move back and forth on the ultraviolet light source 9. The movement of the movable sleeve 17 back and forth on the ultraviolet light source 9 can clean the surface of the ultraviolet light source 9, avoiding the situation that impurities in the wastewater adhere to the ultraviolet light source 9 and affect the illumination of the ultraviolet light source 9;

[0048] At the same time, through the setting of the flushing mechanism, when the movable sleeve 17 moves downward, the movable sleeve 17 will drive the piston rod 21 to move. The piston rod 21 then drives the piston block 20 to move downward inside the piston tube 19. Under the action of suction, the wastewater and the ozone water at the middle position inside the treatment barrel 3 will be sucked into the inside of the piston tube 19 through the water inlet hole 22. At the same time, due to the setting of the water outlet hole 23, the wastewater and the ozone water below the treatment barrel 3 will also be sucked into the inside of the piston tube 19. However, since the inside of the water outlet hole 23 gradually becomes smaller from the inside to the outside, the amount of wastewater and ozone water entering the inside of the piston tube 19 through the water outlet hole 23 is much smaller than the amount entering through the water inlet hole 22. As the movable sleeve 17 moves upward, the piston block 20 will also move upward inside the piston tube 19, thereby squeezing the wastewater and the ozone water inside the piston tube 19. At this time, the wastewater and the ozone water inside the piston tube 19 will be discharged from the inside of the piston tube 19 through the water outlet hole 23 and the water inlet hole 22. Due to the shapes of the water inlet hole 22 and the water outlet hole 23, the amount of wastewater and ozone water discharged from the inside of the piston tube 19 through the water outlet hole 23 is greater than the amount discharged from the water inlet hole 22. Thus, the wastewater and the ozone water above the filter barrel 2 can be transferred to the lower part inside the treatment barrel 3, further improving the contact between the wastewater and the ozone water and the nano-channel filter screen 8, enhancing the mixing effect of the wastewater and the ozone water, and further enhancing the reaction effect.
