Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a treatment device and a treatment method based on sewage after distillation. Background Art

[0002] In numerous industrial fields, including chemical, petroleum, environmental protection, pharmaceuticals, and food processing, distillation towers play a crucial role as core equipment for precise separation and efficient purification of mixtures. The distillation process separates the components of a mixture through repeated vaporization and condensation based on the differences in boiling points of different substances. However, this process produces wastewater containing a variety of pollutants. If these pollutants are discharged directly without treatment, they will cause serious pollution to the atmosphere, water bodies, and soil environment, endangering ecological balance, and threatening human health and biodiversity. Therefore, we urgently need a treatment device and method for distilled wastewater.

[0003] At present, the treatment method for pollutants after distillation is spray treatment, that is, spraying to mix sewage with reaction gas to treat sewage and remove pollutants in sewage. However, during the gas-liquid mixing reaction, since sewage and reaction gas are transported into the reaction chamber from top to bottom, the contact area between gas and liquid is limited, which will lead to low gas-liquid reaction efficiency. Simple spraying method will cause uneven gas-liquid mixing, which will affect the removal effect and efficiency of pollutants. Summary of the Invention

[0004] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a treatment device and a treatment method based on distilled wastewater, which improves the removal effect and efficiency of pollutants in wastewater by improving the wastewater treatment method.

[0005] The technical solutions adopted in the present invention are as follows:

[0006] A treatment device and treatment method based on post-distillation sewage, comprising: a sewage treatment barrel, a plurality of mixing treatment parts, and a driving mechanism, wherein the mixing treatment part is located in the sewage treatment barrel and connected to the sewage treatment barrel, the plurality of mixing treatment parts are sequentially distributed from top to bottom, and the plurality of mixing treatment parts are used for cascade treatment of sewage, each of the mixing treatment parts comprising: a sewage treatment chamber, a plurality of sewage inlet pipes, and a reaction gas inlet part, the sewage inlet pipes being installed at the top of the sewage treatment chamber and injecting sewage to be treated into the sewage treatment chamber from top to bottom, the reaction gas inlet part being installed on the side wall of the sewage treatment chamber, the reaction gas inlet part injecting reaction gas into the sewage treatment chamber from bottom to top, the sewage flowing from top to bottom being mixed with the reaction gas flowing from bottom to top to achieve the removal of pollutants in the sewage, the driving mechanism being connected to the sewage treatment barrel, the driving end of the driving mechanism being connected to the reaction gas inlet part, and the driving mechanism being used to drive the reaction gas inlet part to rotate along the axial direction of the sewage treatment barrel.

[0007] Therefore, compared with the existing sewage mixing reaction method, the design of the sewage inlet pipe for injecting sewage from top to bottom and the reaction gas inlet part for injecting reaction gas from bottom to top is simple in structure and easy to operate. The two forces in different directions of injecting sewage from top to bottom and injecting reaction gas from bottom to top can increase the contact area between sewage and reaction gas. At the same time, the two forces in different directions can impact each other to ensure that the sewage and reaction gas are fully mixed, thereby improving the removal effect and removal efficiency of pollutants in sewage; in addition, the reaction gas inlet part is driven by the driving mechanism to rotate along the axial direction of the sewage treatment cylinder, so that the reaction gas injected from bottom to top can also rotate axially, which can not only generate an impact force from bottom to top, but also generate a cutting force in the circumferential direction. In this way, under the action of the two-way force of impact force and cutting force, it is further ensured that the sewage and reaction gas are fully mixed, thereby further improving the removal effect and removal efficiency of pollutants in sewage.

[0008] As a further improvement of the above technical solution: the mixing treatment part also includes: a top plate, the sewage inlet pipe is installed on the top plate, the top plate is fixedly connected to the inner wall of the sewage treatment cylinder, the top plate and the reaction gas inlet part form the sewage treatment chamber, and the sewage inlet pipe is connected to the sewage treatment chamber.

[0009] As a further improvement to the above technical solution: the reaction gas inlet portion includes: a storage chamber, multiple spray pipes, and multiple first through holes. The storage chamber and the top plate form the sewage treatment chamber. The storage chamber is rotatably connected to the inner wall of the sewage treatment barrel. The storage chamber is a hollow structure. The spray pipes are installed on the top of the storage chamber and are connected to the storage chamber. The multiple spray pipes are distributed in an annular shape with equal spacing. The spray pipes are tilted and the tilt direction is set upward. The spray pipes are provided with multiple first through holes, and the first through holes are located on the side of the spray pipes close to the top plate. As a result, the contact area between the sewage to be treated and the reaction gas can be further expanded by the multiple spray pipes, and the contact area between the sewage to be treated and the reaction gas can be further expanded by the multiple first through holes, so as to further ensure that the sewage and the reaction gas are fully mixed.

[0010] As a further improvement to the above technical solution, the invention further comprises: an air inlet pipe, a first connecting pipe, and a drain pipe. The air inlet pipe is mounted at the bottom of the sewage treatment barrel, the first connecting pipe is mounted inside the sewage treatment barrel, the first connecting pipe is rotatably connected to the air inlet pipe, the first connecting pipe passes through the storage chamber and is fixedly connected to the storage chamber, and the first connecting pipe passes through the top plate and is rotatably connected to the top plate. Thus, the reaction gas enters the sewage treatment barrel through the air inlet pipe and is ultimately injected into the sewage treatment chamber through the first connecting pipe.

[0011] As a further improvement to the above technical solution, the first connecting pipe is provided with a plurality of second through-holes, which are located within the storage chamber. Thus, through the second through-holes in the first connecting pipe, the reaction gas is injected into the sewage treatment cylinder via the intake pipe, and then passes through the first connecting pipe, the storage chamber, the spray pipe, and finally ejected through the first through-holes.

[0012] As a further improvement of the above technical solution: the reaction gas inlet part also includes: two scrapers, the scrapers are located at the top of the storage chamber, the two scrapers are arranged opposite to each other, the scrapers are fixedly connected to the inner wall of the sewage treatment barrel, the scrapers are rotatably connected to the storage chamber, and the side of the scrapers away from the top plate is in contact with the storage chamber; the longitudinal cross-section of the storage chamber is conical. Therefore, since the scrapers are fixedly connected to the inner wall of the sewage treatment barrel and rotatably connected to the storage chamber, during the process of the driving member driving the storage chamber to rotate, the relative movement between the scrapers and the storage chamber can scrape off the impurities after the sewage and the reaction gas are mixed, so as to scrape them to the position of the slag discharge pipe and finally discharge them through the slag discharge pipe; in addition, the relative movement between the scrapers and the storage chamber can also generate disturbances to the sewage and the reaction gas, and this disturbance can further ensure that the sewage and the reaction gas are fully mixed.

[0013] As a further improvement to the above technical solution, the reaction gas inlet section further includes two slag discharge pipes and multiple second connecting pipes. The slag discharge pipes extend through the sewage treatment cylinder, and the second connecting pipes extend through the storage chamber and communicate with the sewage treatment chamber. Thus, fixed impurities generated during the mixing of sewage and reaction gas are discharged through the slag discharge pipes. The second connecting pipes facilitate the downward flow of sewage through multiple mixing and treatment sections, achieving cascaded sewage treatment.

[0014] As a further improvement to the above technical solution: the drive mechanism includes a drive member, a first gear, and a second gear. The drive member is connected to the sewage treatment barrel, the first gear is mounted at the output end of the drive member, the first gear meshes with the second gear, and the second gear is sleeved on the first connecting pipe. Thus, when the drive member is activated, the first gear is driven to rotate, which in turn drives the second gear to rotate. This causes the first connecting pipe to rotate, which in turn drives the reaction gas inlet portion to rotate, so that the reaction gas injected from the bottom up can generate an impact force from the bottom up, as well as a cutting force in the circumferential direction.

[0015] As a further improvement to the above technical solution, the present invention further comprises a water inlet pipe installed at the top of the sewage treatment cylinder and connected to the sewage inlet pipe. Thus, sewage to be treated enters the sewage treatment cylinder through the water inlet pipe and is injected into the sewage treatment chamber through the sewage inlet pipe for treatment in the sewage treatment chamber.

[0016] A treatment method based on a treatment device for post-distillation wastewater comprises the following steps:

[0017] S1. Injecting sewage to be treated into the sewage treatment chamber through the sewage inlet pipe, and injecting reaction gas into the sewage treatment chamber through the reaction gas inlet part;

[0018] S2. Start the driving mechanism and drive the reaction gas inlet part to rotate around the axis of the sewage treatment cylinder through the driving mechanism, so that the reaction gas moving from the lower net rotates and mixes with the sewage from top to bottom to achieve the removal of pollutants in the sewage.

[0019] The beneficial effects of the present invention are as follows:

[0020] Through the design of the sewage inlet pipe for injecting sewage from top to bottom and the reaction gas inlet part for injecting reaction gas from bottom to top, compared with the existing sewage mixing reaction method, this method has a simple structure and is easy to operate. The injection of sewage from top to bottom and the injection of reaction gas from bottom to top, the two forces in different directions, can increase the contact area between sewage and reaction gas. At the same time, the forces in two different directions can impact each other to ensure that the sewage and reaction gas are fully mixed, thereby improving the removal effect and removal efficiency of pollutants in sewage; in addition, the reaction gas inlet part is driven by the driving mechanism to rotate along the axial direction of the sewage treatment cylinder, so that the reaction gas injected from bottom to top can also rotate axially, which can not only generate an impact force from bottom to top, but also generate a cutting force in the circumferential direction. In this way, under the action of the two-way force of impact force and cutting force, it is further ensured that the sewage and reaction gas are fully mixed, thereby further improving the removal effect and removal efficiency of pollutants in sewage.

[0021] The present invention also includes the following advantages:

[0022] 1. The present invention can further expand the contact area between the sewage to be treated and the reaction gas through multiple spray pipes and multiple first through holes, thereby further ensuring that the sewage and the reaction gas are fully mixed.

[0023] 2. In the present invention, the scraper is fixedly connected to the inner wall of the sewage treatment barrel and is rotatably connected to the storage chamber. During the process of the driving member driving the storage chamber to rotate, the relative movement between the scraper and the storage chamber can scrape off the impurities mixed with the sewage and the reaction gas, so as to scrape them to the position of the slag discharge pipe and finally discharge them through the slag discharge pipe. In addition, the relative movement between the scraper and the storage chamber can also generate disturbances to the sewage and the reaction gas, and the disturbances can further ensure that the sewage and the reaction gas are fully mixed.

[0049] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0050] like Figures 1 to 8As shown, a treatment device based on distilled sewage includes: a sewage treatment barrel 1, multiple mixing treatment parts 2 and a driving mechanism 6. The mixing treatment part 2 is located in the sewage treatment barrel 1 and is connected to the sewage treatment barrel 1. The multiple mixing treatment parts 2 are distributed in sequence from top to bottom. The multiple mixing treatment parts 2 are used for cascade treatment of sewage. Each mixing treatment part 2 includes: a sewage treatment chamber 3, multiple sewage inlet pipes 4 and a reaction gas inlet part 5. The sewage inlet pipe 4 is installed at the top of the sewage treatment chamber 3 and injects the sewage to be treated into the sewage treatment chamber 3 from top to bottom. The reaction gas inlet part 5 is installed on the side wall of the sewage treatment chamber 3. The reaction gas inlet part 5 injects the reaction gas into the sewage treatment chamber 3 from bottom to top. The sewage flowing from top to bottom is mixed with the reaction gas flowing from bottom to top to achieve the removal of pollutants in the sewage. The driving mechanism 6 is connected to the sewage treatment barrel 1, and the driving end of the driving mechanism 6 is connected to the reaction gas inlet part 5. The driving mechanism 6 is used to drive the reaction gas inlet part 5 to rotate along the axial direction of the sewage treatment barrel 1. Therefore, compared with the existing sewage mixing reaction method, the design of the sewage inlet pipe 4 for injecting sewage from top to bottom and the reaction gas inlet part 5 for injecting reaction gas from bottom to top is simple in structure and easy to operate. The two forces in different directions of injecting sewage from top to bottom and injecting reaction gas from bottom to top can increase the contact area between sewage and reaction gas. At the same time, the forces in two different directions can impact each other to ensure that the sewage and reaction gas are fully mixed, thereby improving the removal effect and removal efficiency of pollutants in sewage; in addition, the reaction gas inlet part 5 is driven by the driving mechanism 6 to rotate along the axial direction of the sewage treatment barrel 1, so that the reaction gas injected from bottom to top can also rotate axially, which can not only generate an impact force from bottom to top, but also generate a cutting force in the circumferential direction. In this way, under the action of the bidirectional force of impact force and cutting force, the sewage and reaction gas are further ensured to be fully mixed, thereby further improving the removal effect and removal efficiency of pollutants in sewage.

[0051] In this embodiment, the mixing treatment part 2 also includes: a top plate 7, a sewage inlet pipe 4 is installed on the top plate 7, the top plate 7 is fixedly connected to the inner wall of the sewage treatment barrel 1, the top plate 7 and the reaction gas inlet part 5 to form a sewage treatment chamber 3, and the sewage inlet pipe 4 is connected to the sewage treatment chamber 3; the reaction gas inlet part 5 includes: a storage chamber 501, a plurality of spray pipes 502, a plurality of first through holes 503, two scrapers 504, two slag discharge pipes 505 and a plurality of second connecting pipes 506, the storage chamber 501 and the top plate 7 to form a sewage treatment chamber 3, the storage chamber 501 is rotatably connected to the inner wall of the sewage treatment barrel 1, the storage chamber 501 is a hollow structure, the spray pipe 502 is installed on the top of the storage chamber 501 and is connected to the storage chamber 501, The spray pipes 502 are distributed in a ring shape with equal intervals. The spray pipes 502 are inclined and the inclination direction is upward. A plurality of first through holes 503 are opened on the spray pipe 502, and the first through hole 503 is located on the side of the spray pipe 502 close to the top plate 7. The scraper 504 is located at the top of the storage chamber 501. The two scrapers 504 are arranged opposite to each other. The scraper 504 is fixedly connected to the inner wall of the sewage treatment barrel 1. The scraper 504 is rotatably connected to the storage chamber 501, and the side of the scraper 504 away from the top plate 7 is in contact with the storage chamber 501; the longitudinal cross-section of the storage chamber 501 is conical, the slag discharge pipe 505 passes through the sewage treatment barrel 1, the second connecting pipe 506 passes through the storage chamber 501, and the second connecting pipe 506 is connected to the sewage treatment chamber 3. Thus, the contact area between the sewage to be treated and the reaction gas can be further expanded through the multiple spray pipes 502, and the contact area between the sewage to be treated and the reaction gas can be further expanded through the multiple first through holes 503, so as to further ensure that the sewage and the reaction gas are fully mixed. Since the scraper 504 is fixedly connected to the inner wall of the sewage treatment barrel 1 and is rotatably connected to the storage chamber 501, when the driving member 601 drives the storage chamber 501 to rotate, the relative movement between the scraper 504 and the storage chamber 501 can scrape off impurities mixed with the sewage and the reaction gas, and scrape them to the position of the slag discharge pipe 505, and finally discharge them through the slag discharge pipe 505. In addition, the relative movement between the scraper 504 and the storage chamber 501 can also generate disturbances to the sewage and the reaction gas, and the disturbances can further ensure that the sewage and the reaction gas are fully mixed. The fixed impurities generated during the mixing of the sewage and the reaction gas are discharged through the slag discharge pipe 505. The second connecting pipe 506 facilitates the sewage to flow from top to bottom, so as to pass through the multiple mixing treatment parts 2 to achieve cascade treatment of the sewage.

[0052] It should be noted that:

[0053] 1. The first through hole 503 is located directly below the sewage inlet pipe 4. This arrangement ensures that the sewage injected from the top down and the reaction gas injected from the bottom up can impact each other, thereby generating an interaction force to promote the thorough mixing of the sewage and the reaction gas;

[0054] Second, the spray pipe 502 is tilted and tilted upward, which means that the inlet end of the spray pipe 502 is located at the bottom of the outlet end;

[0055] 3. The inclination angles of the multiple spray pipes 502 (i.e., the inclination angles relative to the top plate 7) are different. This ensures that the contact positions between the reaction gas ejected from each first through hole 503 and the sewage injected by the sewage inlet pipe 4 are different. In conjunction with the rotation of the reaction gas inlet portion 5, the action positions of the sewage and the reaction gas in the entire sewage treatment chamber 3 are different. This further increases the contact area between the sewage and the reaction gas, thereby further ensuring that the sewage and the reaction gas are fully mixed (that is, the present application uses the combined effect of four methods: the mutual impact force generated by the sewage injected from top to bottom and the reaction gas injected from bottom to top, the circumferential cutting force generated by the rotating reaction gas inlet portion 5, the different inclination angles of the spray pipes 502 to ensure that the sewage and the reaction gas act at different positions, and the relative movement between the storage chamber 501 and the scraper 504 to generate a disturbing force, to increase the contact area between the sewage and the reaction gas, thereby ensuring that the sewage and the reaction gas are fully mixed).

[0056] 4. The rotation angle of the reaction gas inlet 5 and the first connecting pipe 9 is greater than 0° and less than 180°.

[0057] In this embodiment, the wastewater treatment system further includes an air inlet pipe 8, a first connecting pipe 9, and a drain pipe 10. The air inlet pipe 8 is mounted at the bottom of the wastewater treatment barrel 1, and the first connecting pipe 9 is mounted inside the wastewater treatment barrel 1. The first connecting pipe 9 is rotatably connected to the air inlet pipe 8, passes through the storage chamber 501, is fixedly connected thereto, and passes through the top plate 7, is rotatably connected thereto. The first connecting pipe 9 defines a plurality of second through-holes 901, which are located inside the storage chamber 501. Thus, the reactant gas enters the wastewater treatment barrel 1 through the air inlet pipe and is ultimately injected into the wastewater treatment chamber 3 through the first connecting pipe 9. The reactant gas is injected into the wastewater treatment barrel 1 through the second through-holes 901 defined in the first connecting pipe 9, and then sequentially passes through the first connecting pipe 9, the storage chamber 501, and the spray pipe 502, before being ejected through the first through-holes 503.

[0058] In this embodiment, the drive mechanism 6 includes a drive member 601, a first gear 602, and a second gear 603. The drive member 601 is connected to the sewage treatment barrel 1, and the first gear 602 is mounted on the output end of the drive member 601. The first gear 602 meshes with the second gear 603, and the second gear 603 is sleeved on the first connecting pipe 9. Thus, when the drive member 601 is activated, the first gear 602 is driven by the drive member 601 to rotate, which in turn drives the second gear 603 to rotate. In this way, the first connecting pipe 9 rotates, which in turn drives the reaction gas inlet portion 5 to rotate, so that the reaction gas injected from the bottom up can generate an impact force from the bottom up and a cutting force in the circumferential direction.

[0059] For example, the driving member 601 is a motor.

[0060] In this embodiment, the present invention further comprises a water inlet pipe 11, which is mounted on the top of the sewage treatment barrel 1 and is connected to the sewage inlet pipe 4. Thus, sewage to be treated enters the sewage treatment barrel 1 through the water inlet pipe 11 and is injected into the sewage treatment chamber 3 through the sewage inlet pipe 4, where it is treated.

[0061] Specifically, the water inlet pipe 11 includes: a first water inlet branch pipe 12 and a second water inlet branch pipe 13. The first water inlet branch pipe 12 runs through the sewage treatment cylinder 1. The outlet end of the first water inlet branch pipe 12 is connected to the inlet end of the second water inlet branch pipe 13. The sewage inlet pipe 4 is connected to the outlet end of the second water inlet branch pipe 13. The sewage to be treated enters the first water inlet branch pipe 12 and is evenly diffused into the second water inlet branch pipe 13, and then enters the sewage treatment chamber 3 through the sewage inlet pipe 4.

[0062] It should be noted that: in this embodiment, there are three mixed treatment parts 2, which are recorded from top to bottom as: A sewage treatment part, B sewage treatment part, and C sewage treatment part. The inlet end of the sewage inlet pipe 4 of the sewage treatment part A is connected to the second water inlet branch pipe 13, and the outlet end of the sewage inlet pipe 4 of the sewage treatment part A is connected to the sewage treatment chamber 3 of the sewage treatment part A. The inlet end of the second connecting pipe 506 of the sewage treatment part A is connected to the sewage treatment chamber 3 of the sewage treatment part A, and the outlet end of the second connecting pipe 506 of the sewage treatment part A is connected to the sewage treatment chamber 3 of the sewage treatment part B. The inlet end of the water inlet pipe 4 is connected (the connection is not a fixed connection, but a connection when the reaction gas inlet part 5 of the A sewage treatment part is rotated to connect with the outlet end of the second connecting pipe 506 of the A sewage treatment part), the outlet end of the sewage inlet pipe 4 of the B sewage treatment part is connected to the sewage treatment chamber 3 of the B sewage treatment part, the inlet end of the second connecting pipe 506 of the B sewage treatment part is connected to the sewage treatment chamber 3 of the B sewage treatment part, and the outlet end of the second connecting pipe 506 of the B sewage treatment part is connected to the inlet end of the sewage inlet pipe 4 of the C sewage treatment part (the connection is not a fixed connection, but a connection when the reaction gas inlet part 5 of the A sewage treatment part is rotated to connect with the outlet end of the second connecting pipe 506 of the A sewage treatment part), The outlet end of the sewage inlet pipe 4 of the C sewage treatment unit is connected to the sewage treatment chamber 3 of the C sewage treatment unit, and the inlet end of the second connecting pipe 506 of the C sewage treatment unit is connected to the sewage treatment chamber 3 of the B sewage treatment unit. The outlet end of the second connecting pipe 506 of the C sewage treatment unit is connected to the sewage treatment chamber 3 of the B sewage treatment unit, and the outlet end of the second connecting pipe 506 of the C sewage treatment unit is connected to the inlet end of the drain pipe 10 through the connector 14 (that is, the connector 14 is installed at the reaction gas inlet portion 5 of the C sewage treatment unit). The bottom of the sewage treatment cylinder 1 is fixedly connected to the inner wall of the sewage treatment cylinder 1, and the connector 14 is connected to the inlet end of the drain pipe 10). In this way, the sewage is injected into the sewage treatment cylinder 1 through the first inlet branch pipe, and passes through the second water inlet branch pipe 13, the sewage treatment chamber 3 of the sewage treatment unit A (the first sewage treatment), the sewage treatment chamber 3 of the sewage treatment unit B (the second sewage treatment), and the sewage treatment chamber 3 of the sewage treatment unit C (the third sewage treatment). After three levels of sewage treatment, the sewage is finally discharged through the drain pipe 10 through the connector 14.

[0063] The sewage treatment process of the present invention is: first, the sewage to be treated is injected through the first water inlet branch pipe 12, and the reaction gas is injected through the air inlet pipe 8; then, the driving member 601 is started to rotate the reaction gas inlet part 5 of the A mixing treatment part 2, the reaction gas inlet part 5 of the B mixing treatment part 2, and the reaction gas inlet part 5 of the C mixing treatment part 2, and the sewage is injected into the sewage treatment chamber 3 of the A mixing treatment part 2 through the second water inlet branch pipe 13 and the sewage inlet pipe 4 of the A mixing treatment part 2, and the reaction gas is injected into the sewage treatment chamber 3 of the A mixing treatment part 2 through the reaction gas inlet part 5 of the A mixing treatment part 2 to achieve the first treatment of the sewage; then, the sewage after the first treatment is injected into the sewage treatment chamber 3 of the B mixing treatment part 2 through the second connecting pipe 506 of the A mixing treatment part 2 and the sewage inlet pipe 4 of the B mixing treatment part 2, and the reaction gas is passed through the connecting pipe 507 of the A mixing treatment part 2. The reaction gas inlet part 5 of the B mixing treatment part 2 is injected into the sewage treatment chamber 3 of the B mixing treatment part 2 to achieve the second treatment of the sewage; then, the sewage after the second treatment is injected into the sewage treatment chamber 3 of the C mixing treatment part 2 through the second connecting pipe 506 of the B mixing treatment part 2 and the sewage inlet pipe 4 of the C mixing treatment part 2, and the reaction gas is injected into the sewage treatment chamber 3 of the C mixing treatment part 2 through the reaction gas inlet part 5 of the C mixing treatment part 2 to achieve the third treatment of the sewage; finally, the sewage after the third treatment flows into the connector 14 through the second connecting pipe 506 of the C mixing treatment part 2, and is finally discharged through the drain pipe 10, and the sewage discharged from the drain pipe 10 is tested. If it meets the requirements, it is directly discharged. If it does not meet the requirements, it is re-flowed into the first water inlet branch pipe 12 and re-treated until it meets the requirements and is discharged.

[0064] like Figure 9 As shown, a treatment method based on a treatment device for sewage after distillation comprises the following steps:

[0065] S1. Injecting sewage to be treated into the sewage treatment chamber 3 through the sewage inlet pipe 4 and injecting reaction gas into the sewage treatment chamber 3 through the reaction gas inlet portion 5;

[0066] S2. Start the driving mechanism 6, and drive the reaction gas inlet part 5 to rotate around the axis of the sewage treatment cylinder 1 through the driving mechanism 6, so that the reaction gas moving from the lower net rotates and mixes with the sewage from top to bottom, so as to remove pollutants in the sewage.

[0067] To sum up, the present invention adopts the design mode of the sewage inlet pipe 4 for injecting sewage from top to bottom and the reaction gas inlet part 5 for injecting reaction gas from bottom to top. Compared with the existing sewage mixing reaction mode, this mode has a simple structure and is easy to operate. The sewage is injected from top to bottom and the reaction gas is injected from bottom to top. The two forces in different directions can increase the contact area between the sewage and the reaction gas. At the same time, the forces in two different directions can impact each other to ensure that the sewage and the reaction gas are fully mixed, thereby improving the removal effect and removal efficiency of pollutants in the sewage; in addition, the reaction gas inlet part 5 is driven by the driving mechanism 6 to rotate along the axial direction of the sewage treatment barrel 1, so that the reaction gas injected from bottom to top can also rotate axially, which can not only generate an impact force from bottom to top, but also generate a cutting force in the circumferential direction. In this way, under the action of the bidirectional force of the impact force and the cutting force, the sewage and the reaction gas are further ensured to be fully mixed, thereby further improving the removal effect and removal efficiency of pollutants in the sewage.

[0068] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
