Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to an oil removal and slag skimming device for a sewage treatment plant. Background Art

[0002] In sewage treatment plants, a layer of grease and debris usually floats on the surface of the sewage. Existing treatment methods often use large-scale professional equipment such as deacidification tanks or flotation tanks. However, the above equipment often occupies a large area, has high engineering costs, and requires a large amount of labor to install, thereby increasing the cost of use.

[0003] The patent with the patent announcement number CN221607880U discloses an oil removal and skimming device for a sewage treatment plant, which relates to the technical field of sewage treatment, and includes a device body, a support leg arranged at the bottom of the device body, and a pre-filtering device arranged at the top of the device body, wherein the top of the pre-filtering device is fixedly connected with a liquid inlet funnel, a processing mechanism is arranged inside the device body, and a processing device is arranged at the top of the device body. The patent utilizes the cooperation between the filter plate and the oil absorption plate. Since the filter membrane and the oil absorption membrane are arranged inside the two, the introduced sewage can be filtered and oil can be absorbed. The clamping plate is then used to facilitate the replacement of the filter plate. Then, the cooperation between the push plate and the push rod is set to push the oil removal scraping plate, and then the absorbed oil residue on the surface of the oil absorption plate is scraped off, and it is pushed to the inside of the recovery box for recovery, thereby improving the utilization efficiency of the device.

[0004] However, the device still has some shortcomings: the device can remove oil and scrape wastewater, but the factory wastewater is prone to carry tiny iron filings. The tiny iron filings are easily caused to wear internal parts of the equipment during the sewage treatment steps such as stirring the sewage simultaneously. At the same time, the iron filings are easily oxidized and volatilized into harmful substances when mixed with sewage for a long time, thereby increasing the difficulty of sewage treatment. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an oil removal and slag skimming device for a sewage treatment plant, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an oil removal and skimming device for a sewage treatment plant, comprising a device body, a funnel is arranged on the top of the device body, a base is arranged at the bottom of the device body, a drain pipe is arranged at the center of the bottom of the device body, a material extraction component is arranged on the outer wall of the device body, and a disinfection component is arranged below the outer wall of the device body; An anti-wear device is arranged inside the main body of the device, a uniform device is arranged below the anti-wear device, and an efficiency-enhancing device is arranged inside the uniform device; The anti-wear device comprises a filter plate, the outer wall of the filter plate is fixedly installed above the inner wall of the device body, an electric rotating rod is rotatably installed at the bottom edge of the filter plate, the bottom of the electric rotating rod is rotatably connected to the bottom of the inner wall of the device body, a reciprocating spiral groove is opened above the outer wall of the electric rotating rod, a magnetic plate is arranged on the outer wall of the reciprocating spiral groove of the electric rotating rod, an oil-absorbing cotton block is fixedly installed on the top of the magnetic plate, a screw rod is rotatably installed inside the filter plate, the outer wall of the screw rod passes through and is threadedly connected to the inside of the magnetic plate, a plurality of stirring plates are fixedly installed above the outer wall of the screw rod, and sieve plates are slidably installed inside the plurality of stirring plates through springs, a plurality of vertical plates are equidistantly and fixedly installed on the top of the inner wall of the device body, the device body introduces sewage into itself through a funnel, and intercepts larger particle impurities in the sewage through the filter plate. At this time, the material extraction component passes through an external pipe Enter the inside of the device body and extract impurities, and start the electric rotating rod at the same time. When the electric rotating rod rotates, the reciprocating spiral groove on its outer wall drives the built-in card block of the magnetic plate, so that the magnetic plate can slide back and forth upward along the outer wall of the electric rotating rod and reset, and the magnetic plate drives the oil-absorbing cotton block to move synchronously. When the oil-absorbing cotton block moves upward, it contacts with the bottom of the filter plate to generate resistance and deform. When the sewage falls into the inside of the oil-absorbing cotton block, the deformation and squeezing of the oil-absorbing cotton block causes the sewage to be quickly discharged and fall; when the magnetic plate moves upward, it contacts the outer wall of the spirally connected screw rod, causing the screw rod to generate a rotating force and start to rotate, the screw rod drives the stirring plate to rotate, and the stirring plate drives the screen plate to move synchronously. When the screen plate revolves, it contacts the arc surface at the bottom of the vertical plate to generate resistance. At this time, the screen plate slides downward along the inner wall of the stirring plate through the resistance force of the vertical plate, and when the screen plate passes over the vertical plate, it is reset by the elastic force of the spring, and so on.

[0007] According to the above technical solution, the top of the oil-absorbing cotton block contacts the bottom of the filter plate, a plurality of the stirring plates are equidistantly distributed on the outer wall of the screw, and the bottoms of a plurality of the vertical plates are all located on the movement trajectory of the top of the screen plate.

[0008] According to the above technical scheme, the uniform device includes a plurality of bending frames, a fixed plate, a through rod and a swinging plate. The tops of the plurality of bending frames are equidistant and fixedly installed at the bottom edge of the screw rod. The fixed plate is fixedly installed on the inner wall of the bending frame away from the center of the device body. Both ends of the through rod are fixedly installed inside the fixed plate. The inside of the swinging plate is hinged to the outer wall of the through rod through a torsion spring. Disinfectant is added to the inside of the device body through the disinfection assembly. At the same time, when the screw rod rotates, it drives the bending frame to revolve, and the bending frame drives the fixed plate to move synchronously. The fixed plate drives the through rod to move synchronously. When the through rod drives the swinging plate to revolve, the swinging plate contacts the sewage inside the device body to generate resistance, which prompts the swinging plate to generate a rotational force. At this time, the swinging plate relies on the resistance to rotate along the outer wall of the through rod to form an inclined distribution. When the screw rod stops rotating, the swinging plate is reset by the torsion spring.

[0009] According to the above technical scheme, the uniformity device also includes a transmission ring, an elastic telescopic rod, a heating component, a semicircular block and a resistance block, the top of the transmission ring is fixedly installed on the bottom of the bending frame, the fixed end of the elastic telescopic rod is fixedly installed on the inner wall of the transmission ring away from the center of the device body, the outer wall of the heating component is fixedly installed on the side of the telescopic end of the elastic telescopic rod close to the center of the device body, the semicircular block is fixedly installed on the inner wall of the heating component away from the center of the device body, and the bottom of the resistance block is fixedly installed on the bottom of the inner wall of the device body. When the bending frame rotates, it drives the transmission ring to rotate along the bottom of the inner wall of the device body, the transmission ring drives the elastic telescopic rod to move synchronously, the telescopic end of the elastic telescopic rod drives the heating component to revolve, and the semicircular block is driven to move synchronously when the heating component revolves. When the semicircular block revolves, its outer wall will resist the outer wall of the block to generate a resistance force, prompting the semicircular block to push the heating component to move toward the inner wall of the device body through the resistance force, and the heating component is subsequently reset by the elastic force of the telescopic end of the elastic telescopic rod.

[0010] According to the above technical solution, the bottom of the transmission ring contacts the bottom of the inner wall of the device body, the bottom of the heating component contacts the bottom of the inner wall of the device body, and the arc surface of the resistance block is located on the movement trajectory of the semicircular block.

[0011] According to the above technical scheme, the efficiency improvement device includes a receiving plate, an L-shaped plate and a bubble arc plate. The receiving plate is fixedly installed on the inner wall of the bending frame on one side close to the inner wall of the device body, the bottom of the L-shaped plate is fixedly installed on the top of the semicircular block, the top of the bubble arc plate is slidably installed on the bottom of the receiving plate, and the bubble arc plate is fixedly installed on the top of the L-shaped plate on one side close to the center of the device body. When the semicircular block moves back and forth toward the inner wall of the device body and resets, the semicircular block will drive the L-shaped plate to move synchronously, and the L-shaped plate will push the bubble arc plate to slide synchronously along the bottom of the receiving plate. During the sliding of the bubble arc plate in the water, it contacts the sewage through the bubble holes on its outer wall, and a large number of bubbles are generated when the sewage is suddenly poured into the bubble holes.

The tops of the plurality of activated carbon plates are hinged to the side of the wave guide plate away from the inner wall of the transmission ring through a torsion spring. The L-shaped plate reciprocates toward the inner wall of the device body and drives the wave guide plate to move synchronously when resetting. The wave guide plate realizes revolution and horizontal movement. When the wave guide plate moves toward the inner wall of the device body, it hits the top of the inclined rod, causing the hinge shaft of the inclined rod to start rotating, and the inclined rod is limited by the transmission ring. At this time, the inclined rod will push the wave guide plate to flip toward the center of the device body, and the wave guide plate drives the activated carbon plate to move synchronously. The bottom of the activated carbon plate hits the inner wall of the L-shaped frame to generate a resistance force. At this time, the hinge shaft between the activated carbon plate and the wave guide plate starts to rotate, causing the activated carbon plate to move downward in an arc trajectory along the inner wall of the L-shaped frame. After that, the activated carbon plate is reset by the torsion spring, and this process repeats.

[0013] According to the above technical solution, a torsion spring is arranged between the wave guide plate and the L-shaped plate, and the bottom of the activated carbon plate is in contact with the inner wall of the L-shaped frame.

[0014] The present invention provides an oil removal and slag skimming device for a sewage treatment plant. It has the following beneficial effects: (1) The present invention sets an anti-wear device, and cooperates with the filter plate, electric rotating rod, magnetic plate, oil-absorbing cotton block, screw, stirring plate, screen plate and vertical plate. The oil in the sewage is quickly intercepted by the deformation and extrusion of the oil-absorbing cotton block without affecting the falling of the water flow. The filter plate removes impurities. At the same time, the magnetic plate adsorbs the magnetic micro-chips carried in the sewage during the squeezing and drainage of the oil-absorbing cotton block, effectively preventing the wear of the internal parts of the device body caused by the tiny iron chips during the washing, and preventing the harmful substances volatilized by the oxidation of the iron chips from increasing the difficulty of sewage treatment; at the same time, it effectively expands the stirring range of the sieve plate and the stirring plate on the sewage within their own activity range, thereby quickly dispersing the impurity particles in the sewage entering the internal part of the device body, so that the impurities are evenly distributed on the surface of the filter plate, avoiding the impurities and dirt sticking together to cause the filter plate filter holes to be blocked and increase the difficulty of extraction.

[0015] (2) The present invention adopts the arrangement of a uniform device, and cooperates with a screw rod, a bending frame, a fixed plate, a through rod, a swing plate, a transmission ring, an elastic telescopic rod, a heating component, a semicircular block and a resistance block. The sewage below the magnetic plate is rotated and stirred by the bending frame and the swing plate, thereby promoting the uniform mixing of the disinfectant in the sewage, avoiding the difficulty of the concentrated part of the disinfectant to be quickly dissolved in the water, thereby reducing the disinfection effect on the sewage, and further improving the sewage treatment quality; and effectively expanding the range of the activity of the heating component to ensure that the water temperature inside the device body rises evenly, so that the disinfectant can quickly volatilize its own disinfectant components and dissolve in the sewage when the water temperature rises, avoiding the difficulty of the disinfectant to be fully volatilized at low temperature and then be directly discharged, resulting in waste of resources and reducing the sewage treatment effect.

[0016] (3) The present invention adopts the setting of the efficiency-enhancing device, and cooperates with the semicircular block, the receiving plate, the L-shaped plate, the bubble arc plate, the wave guide plate, the inclined rod, the L-shaped frame and the activated carbon plate. The bubbles float upward and then explode to increase the contact area between sewage and air, accelerate the release and reabsorption of dissolved oxygen in sewage, thereby promoting the growth of microorganisms, and decompose organic matter in sewage through microorganisms, thereby effectively improving the disinfection and purification effects of sewage. At the same time, the wave surface of the wave guide plate is used to reduce the contact distance between the bubble arc plate and the surrounding sewage, increase the contact frequency between the bubble arc plate and sewage in the same time, increase the density of bubble generation, and further improve the decomposition of organic matter in sewage. At the same time, the activated carbon plate purifies the decomposed organic matter in the sewage during the reciprocating swing, thereby reducing the foul odor generated when sewage is discharged.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 8 , one embodiment of the present invention is: an oil removal and skimming device for a sewage treatment plant, comprising a device body 1, a funnel is arranged on the top of the device body 1, a base 2 is arranged at the bottom of the device body 1, a drain pipe 3 is arranged at the center of the bottom of the device body 1, a material extraction component 31 is arranged on the outer wall of the device body 1, and a disinfection component 32 is arranged below the outer wall of the device body 1; An anti-wear device 4 is provided inside the device body 1, a uniform device 5 is provided below the anti-wear device 4, and an efficiency-enhancing device 6 is provided inside the uniform device 5; The anti-wear device 4 includes a filter plate 41, the outer wall of the filter plate 41 is fixedly installed above the inner wall of the device body 1, an electric rotating rod 42 is rotatably installed at the bottom edge of the filter plate 41, the bottom of the electric rotating rod 42 is rotatably connected to the bottom of the inner wall of the device body 1, a reciprocating spiral groove is opened above the outer wall of the electric rotating rod 42, a magnetic plate 43 is arranged on the outer wall of the reciprocating spiral groove of the electric rotating rod 42, an oil-absorbing cotton block 44 is fixedly installed on the top of the magnetic plate 43, a screw rod 45 is rotatably installed inside the filter plate 41, the outer wall of the screw rod 45 passes through and is threadedly connected to the inside of the magnetic plate 43, a plurality of stirring plates 46 are fixedly installed above the outer wall of the screw rod 45, and a sieve plate 47 is slidably installed inside the plurality of stirring plates 46 through springs, and a plurality of vertical plates 48 are equidistantly and fixedly installed on the top of the inner wall of the device body 1 Through the above cooperation, the deformation and extrusion of the oil-absorbing cotton block 44 can quickly intercept the oil in the sewage without affecting the falling of the water flow, and the filter plate 41 removes impurities. At the same time, the magnetic micro-chips carried in the sewage are adsorbed by the magnetic plate 43 during the squeezing and drainage process of the oil-absorbing cotton block 44, which effectively prevents the wear of the internal parts of the device body 1 by the tiny iron chips during the scouring, and at the same time avoids the harmful substances volatilized by the oxidation of the iron chips, which aggravates the difficulty of sewage treatment; through the above cooperation, the stirring range of the sieve plate 47 and the stirring plate 46 for the sewage within their own activity range is effectively expanded, thereby quickly dispersing the impurity particles in the sewage entering the internal part of the device body 1, so that the impurities are evenly distributed on the surface of the filter plate 41, avoiding the impurities and dirt sticking together to cause the filter holes of the filter plate 41 to be blocked and increase the difficulty of extraction.

[0021] The top of the oil-absorbing cotton block 44 contacts the bottom of the filter plate 41 , a plurality of stirring plates 46 are equidistantly distributed on the outer wall of the screw rod 45 , and the bottoms of a plurality of vertical plates 48 are all located on the movement track of the top of the sieve plate 47 .

[0022] When in use, the device body 1 introduces sewage into itself through the funnel, and intercepts larger particles of impurities in the sewage through the filter plate 41. At this time, the extraction component 31 enters the device body 1 through the external pipe and extracts impurities. At the same time, the electric rotating rod 42 is started. When the electric rotating rod 42 rotates, the reciprocating spiral groove on its outer wall drives the built-in block of the magnetic plate 43, so that the magnetic plate 43 can slide reciprocatingly upward along the outer wall of the electric rotating rod 42 and reset. The magnetic plate 43 drives the oil-absorbing cotton block 44 to move synchronously. When the oil-absorbing cotton block 44 moves upward, it contacts with the bottom of the filter plate 41 to generate resistance and deform. When the sewage falls into the oil-absorbing cotton block 44, the deformation and extrusion of the oil-absorbing cotton block 44 cause the sewage to be quickly discharged and fall. Through the above cooperation, the deformation and extrusion of the oil-absorbing cotton block 44 can quickly intercept the oil in the sewage without affecting the falling of the water flow. The filter plate 41 removes impurities. At the same time, during the squeezing and drainage of the oil-absorbing cotton block 44, the magnetic particles carried in the sewage are squeezed by the magnetic plate 43 The micro-chips are adsorbed, which effectively prevents the wear of the internal parts of the device body 1 when the tiny iron chips are washed, and at the same time prevents the harmful substances volatilized by the oxidation of iron chips from aggravating the difficulty of sewage treatment; when the magnetic plate 43 moves upward, it contacts the outer wall of the spirally connected screw rod 45, prompting the screw rod 45 to generate a rotating force and start to rotate, the screw rod 45 drives the stirring plate 46 to rotate, and the stirring plate 46 drives the sieve plate 47 to move synchronously. When the sieve plate 47 revolves, it contacts the curved surface at the bottom of the vertical plate 48 to generate a resistance force. At this time, the sieve plate 47 slides downward along the inner wall of the stirring plate 46 through the resistance force of the vertical plate 48. When the sieve plate 47 passes over the vertical plate 48, it is reset by the spring force, and it repeats like this. Through the above cooperation, the stirring range of the sieve plate 47 and the stirring plate 46 for the sewage within their own activity range is effectively expanded, thereby quickly dispersing the impurity particles in the sewage entering the internal part of the device body 1, so that the impurities are evenly distributed on the surface of the filter plate 41, avoiding the impurities and dirt sticking together to cause the filter holes of the filter plate 41 to be blocked and increase the difficulty of extraction.

[0023] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes a uniform device 5; The uniform device 5 includes a plurality of bending frames 51, a fixed plate 52, a through rod 53 and a swinging plate 54. The tops of the plurality of bending frames 51 are equidistant and fixedly mounted at the bottom edge of the screw rod 45. The fixed plate 52 is fixedly mounted on the inner wall of the bending frame 51 away from the center of the device body 1. Both ends of the through rod 53 are fixedly mounted inside the fixed plate 52. The inside of the swinging plate 54 is hinged to the outer wall of the through rod 53 through a torsion spring. Through the above cooperation, the sewage under the magnetic plate 43 is rotated and stirred by relying on the bending frame 51 and the swinging plate 54, thereby promoting the uniform mixing of the disinfectant in the sewage, avoiding the difficulty of the thick part of the disinfectant to dissolve quickly in water, thereby reducing the disinfection effect on the sewage, and further improving the sewage treatment quality.

[0024] The uniform device 5 also includes a transmission ring 55, an elastic telescopic rod 56, a heating component 57, a semicircular block 58 and a resistance block 59. The top of the transmission ring 55 is fixedly installed at the bottom of the bending frame 51, the fixed end of the elastic telescopic rod 56 is fixedly installed on the inner wall of the transmission ring 55 away from the center of the device body 1, the outer wall of the heating component 57 is fixedly installed on the telescopic end of the elastic telescopic rod 56 close to the center of the device body 1, the semicircular block 58 is fixedly installed on the inner wall of the heating component 57 away from the center of the device body 1, and the bottom of the resistance block 59 is fixedly installed on the bottom of the inner wall of the device body 1. Through the above cooperation, the range of movement of the heating component 57 is effectively expanded, and the water temperature inside the device body 1 is ensured to rise evenly, so that the disinfectant can quickly volatilize its own disinfection components and dissolve in the sewage when the water temperature rises, so as to avoid the disinfectant being difficult to fully volatilize at low temperature and being directly discharged, causing waste of resources and reducing the sewage treatment effect.

[0025] The bottom of the transmission ring 55 contacts the bottom of the inner wall of the device body 1 , the bottom of the heating component 57 contacts the bottom of the inner wall of the device body 1 , and the arc surface of the abutment block 59 is located on the movement track of the semicircular block 58 .

When the through rod 53 drives the swing plate 54 to revolve, the swing plate 54 contacts the sewage in the device body 1 to generate resistance, which prompts the swing plate 54 to generate a rotation force. At this time, the swing plate 54 relies on the resistance to rotate along the outer wall of the through rod 53 to form an inclined distribution. When the screw rod 45 stops rotating, the swing plate 54 is reset by the torsion spring. Through the above cooperation, the sewage under the magnetic plate 43 is rotated and stirred by the bending frame 51 and the swing plate 54, thereby prompting the disinfectant to be evenly mixed in the sewage, avoiding the difficulty of the thick part of the disinfectant to dissolve quickly in water, thereby reducing the disinfection effect on the sewage, and further improving the sewage treatment quality; the bending frame 51 When rotating, the transmission ring 55 is driven to rotate along the bottom of the inner wall of the device body 1, and the transmission ring 55 drives the elastic telescopic rod 56 to move synchronously. The telescopic end of the elastic telescopic rod 56 drives the heating component 57 to revolve, and when the heating component 57 revolves, it drives the semicircular block 58 to move synchronously. When the semicircular block 58 revolves, its outer wall will resist the outer wall of the block 59 to generate a resistance force, prompting the semicircular block 58 to push the heating component 57 to move toward the inner wall of the device body 1 through the resistance force. The heating component 57 is subsequently reset by the elastic force of the telescopic end of the elastic telescopic rod 56. The above cooperation effectively expands the range of activity of the heating component 57, ensures that the water temperature inside the device body 1 rises evenly, and enables the disinfectant to quickly volatilize its own disinfectant components and dissolve in the sewage when the water temperature rises, so as to avoid the disinfectant being difficult to fully volatilize at low temperature and being directly discharged, resulting in waste of resources and reduced sewage treatment effect.

[0027] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an efficiency improvement device 6; The efficiency improvement device 6 includes a receiving plate 61, an L-shaped plate 62 and a bubble arc plate 63.

Through the above cooperation, the bubbles float upward and then explode to increase the contact area between sewage and air, accelerate the release and reabsorption of dissolved oxygen in sewage, thereby promoting the growth of microorganisms, and decompose organic matter in sewage through microorganisms, effectively improving the disinfection and purification effects of sewage.

[0028] The efficiency improvement device 6 also includes a wave guide plate 64, an inclined rod 65, an L-shaped frame 66 and a plurality of activated carbon plates 67. The bottom of the wave guide plate 64 is hinged to the top of the L-shaped plate 62, the bottom of the inclined rod 65 is hinged to the top edge of the transmission ring 55, the top of the inclined rod 65 is hinged to the side of the wave guide plate 64 close to the inner wall of the device body 1, and the L-shaped frame 66 is fixedly installed on the outer wall of the L-shaped plate 62 close to the inner wall of the transmission ring 55. The tops of the plurality of activated carbon plates 67 are hinged to the side of the wave guide plate 64 away from the inner wall of the transmission ring 55 through a torsion spring.

At the same time, the activated carbon plate 67 purifies the decomposed organic matter in the sewage during the reciprocating swinging process, and reduces the odor generated when the sewage is discharged.

[0029] A torsion spring is provided between the wave guide plate 64 and the L-shaped plate 62 , and the bottom of the activated carbon plate 67 contacts the inner wall of the L-shaped frame 66 .

[0030] When in use, the semicircular block 58 moves back and forth toward the inner wall of the device body 1 and resets, the semicircular block 58 will drive the L-shaped plate 62 to move synchronously, and the L-shaped plate 62 pushes the bubble arc plate 63 to slide synchronously along the bottom of the receiving plate 61. During the sliding process of the bubble arc plate 63 in the water, it contacts the sewage through the bubble holes on its outer wall. When the sewage suddenly pours into the bubble holes, a large number of bubbles are generated. Through the above cooperation, the bubbles float upward and then explode to increase the contact area between the sewage and the air, accelerate the release and reabsorption of dissolved oxygen in the sewage, thereby promoting the growth of microorganisms, and decomposing organic matter in the sewage through microorganisms, effectively improving the disinfection and purification effects of the sewage; the L-shaped plate 62 moves back and forth toward the inner wall of the device body 1 and resets, driving the wave guide plate 64 to move synchronously, and the wave guide plate 64 realizes revolution and horizontal movement. When the wave guide plate 64 moves toward the inner wall of the device body 1, it hits the top of the inclined rod 65, prompting the inclined rod The hinge shaft of 65 starts to rotate, and the inclined rod 65 is limited by the transmission ring 55. At this time, the inclined rod 65 will push the wave guide plate 64 to flip toward the center of the device body 1, and the wave guide plate 64 drives the activated carbon plate 67 to move synchronously. The bottom of the activated carbon plate 67 resists the inner wall of the L-shaped frame 66 to generate a resistance force. At this time, the hinge shaft between the activated carbon plate 67 and the wave guide plate 64 starts to rotate, causing the activated carbon plate 67 to move downward along the inner wall of the L-shaped frame 66 in an arc-shaped trajectory. After that, the activated carbon plate 67 is reset by the torsion spring, and this is repeated. Through the above cooperation, the contact distance between the bubble arc plate 63 and the surrounding sewage is reduced by relying on the wave surface of the wave guide plate 64, the contact frequency between the bubble arc plate 63 and the sewage in the same time length is increased, the bubble generation density is increased, and the decomposition of organic matter in the sewage is further improved.
