Description

Technical Field

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

[0002] Sewage treatment (sewage-treatment, wastewater-treatment) is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] The sewage treatment process usually involves multi-stage treatment: Multi-stage treatment is a staged sewage treatment process that aims to gradually remove pollutants from sewage to meet discharge or reuse standards.

[0004] Flocculants are usually added in the initial stage of sewage treatment. The addition of flocculants is mainly used to promote the aggregation of suspended matter and colloidal substances in the water into larger particles, thereby facilitating subsequent treatment steps.

[0005] The existing sewage treatment equipment usually directly extracts flocculants through the pump body for addition during the sewage treatment process, which is not convenient for controlling the amount of flocculants, thereby affecting the flocculation effect of the sewage. At the same time, the existing sewage treatment equipment uses a stirring blade to stir and mix after the flocculants are added. During the stirring and mixing process of the stirring blade, the initially formed floccules are easily broken up, so that the flocculation mechanism cannot achieve the best effect, and there are certain limitations.

Through the treatment method for sewage treatment using a sewage treatment device, it is possible to perform gas injection mixing while quantitatively injecting flocculants.

[0036] The transmission rod 107 drives the first elliptical wheel 201 inside the quantitative adding mechanism 200 to rotate, so that the liquid storage tank 202 cooperates with the quantitative component 204 to quantitatively add flocculant to the sewage treatment tank 101; When the transmission rod 107 rotates, it can drive the second elliptical wheel 301 inside the gas injection and mixing mechanism 300, so that the second elliptical wheel 301 can drive the transmission gas injection component 302 to inject gas into the annular tube 303, so that the gas is ejected through the gas outlet nozzle 304 to mix the sewage and the coagulant.

[0037] The transmission rod 107 rotates to drive the first elliptical wheel 201 to rotate, so that the first elliptical wheel 201 can drive the quantitative component 204 after rotation, so that the quantitative component 204 can quantitatively inject the flocculant in the liquid storage tank 202 into the connecting pipe 206.

When the transmission rod 107 rotates to drive the first elliptical wheel 201 to rotate, it can also drive the second elliptical wheel 301 to rotate. After the second elliptical wheel 301 rotates, it can drive the transmission air injection component 302, so that the transmission air injection component 302 can inject the air inside the air inlet groove 306 into the annular tube 303, and the air is sprayed into the sewage treatment tank 101 through the air outlet nozzle 304 on the annular tube 303, so that the air injected into the sewage treatment tank 101 can mix the sewage, and at the same time, the crushing component 305 can crush the air injected into the sewage treatment tank 101.

[0038] Reference Figures 1 to 3 and Figures 5 and 6 , which is the second embodiment of the present invention, provides a quantitative adding mechanism 200 , through which the quantitative adding mechanism 200 can realize quantitative addition of flocculant and adjust the adding frequency according to the rotation speed of the transmission rod 107 .

[0039] The quantitative adding mechanism 200 includes a first elliptical wheel 201, the top of the transmission rod 107 penetrates to the top of the sewage treatment tank 101, the first elliptical wheel 201 is fixedly connected to the top of the transmission rod 107, the front and rear sides of the top of the sewage treatment tank 101 are fixedly connected with a liquid storage tank 202, the bottom of the liquid storage tank 202 is fixedly connected with a liquid outlet pipe 203, the bottom of the liquid outlet pipe 203 is movably connected with a quantitative component 204, both sides of the first elliptical wheel 201 are movably connected with a pressurized anti-residue component 205, and the tops of the front and back of the sewage treatment tank 101 are fixedly connected with connecting pipes 206.

[0040] The quantitative component 204 includes a movable plate 204a, which is movably connected to the first elliptical wheel 201. A liquid storage tank 204b is provided on the outer side of the top of the movable plate 204a, and the liquid storage tank 204b is connected to the liquid outlet pipe 203. The bottom of the movable plate 204a is movably connected to a sealing plate 204c, and the bottom of the sealing plate 204c is fixedly connected to the top of the sewage treatment tank 101. The outer side of the bottom of the sealing plate 204c is fixedly connected to a Z-shaped tube 204d, the liquid storage tank 204b is connected to the Z-shaped tube 204d, and the bottom end of the Z-shaped tube 204d is fixedly connected to a first one-way valve 204e, and the bottom end of the first one-way valve 204e is connected to the top of the connecting pipe 206. The inner side of the bottom of the sealing plate 204c is fixedly connected to a reset component 204f.

[0041] The reset component 204f includes a fixed plate 204f1, the inner side of the fixed plate 204f1 is fixedly connected to a telescopic rod 204f2, the inner end of the telescopic rod 204f2 is fixedly connected to a connecting plate 204f3, the top of the connecting plate 204f3 is fixedly connected to the bottom of the movable plate 204a, the surface of the telescopic rod 204f2 is sleeved with a first spring 204f4, the outer end of the first spring 204f4 is fixedly connected to the inner side of the fixed plate 204f1, and the inner end of the first spring 204f4 is fixedly connected to the outer side of the connecting plate 204f3.

[0042] The pressurized anti-residue component 205 includes a push plate 205a, which is movably connected to the first elliptical wheel 201, and a piston plate 205b is fixedly connected to the outer side of the push plate 205a. The left and right sides of the top of the sewage treatment tank 101 are fixedly connected to an air box 205d, and an air inlet 205e is provided on the outer side of the top of the air box 205d. There are several air inlets 205e and they are equidistantly distributed. A sealing rubber plate 205f is fixedly connected to the outer side of the top of the inner wall of the air box 205d, and an air outlet pipe 205g is fixedly connected to the surface of the air box 205d. The bottom end of the air outlet pipe 205g is fixedly connected to the second one-way valve 205h, and the bottom end of the second one-way valve 205h is connected to the connecting pipe 206. The outer side of the inner wall of the air box 205d is fixedly connected to the second spring 205i, and the inner end of the second spring 205i is fixedly connected to the inner side of the piston plate 205b.

[0043] Specifically, when the first elliptical wheel 201 rotates, it can drive the movable plate 204a on the sealing plate 204c, so that the movable plate 204a can flow the flocculant inside the liquid storage tank 204b into the Z-shaped tube 204d, so that the flocculant in the Z-shaped tube 204d can enter the connecting tube 206 through the first one-way valve 204e, so that the flocculant injected into the sewage treatment tank 101 through the connecting tube 206 is quantitative each time.

[0044] At the same time, the telescopic rod 204f2 on the fixed plate 204f1 at the bottom of the sealing plate 204c cooperates with the first spring 204f4 to drive the connecting plate 204f3 to move inward, so that the connecting plate 204f3 can drive the movable plate 204a to reset and always contact with the first elliptical wheel 201.

[0045] When the first elliptical wheel 201 rotates, it can drive the push plate 205a to move, so that when the push plate 205a moves inward, it can inject the air inside the air box 205d into the outlet pipe 205g. At the same time, the sealing rubber plate 205f can seal the air inlet 205e, and the second spring 205i on the inner wall of the air box 205d can drive the piston plate 205b and the push plate 205a to reset through its own elastic force, so that the push plate 205a is always in contact with the first elliptical wheel 201, and the air is injected into the sewage treatment tank 101 through the connecting pipe 206, thereby avoiding the flocculant from remaining inside the connecting pipe 206.

[0046] Furthermore, sewage is injected into the sewage bucket 102 inside the sewage treatment tank 101 through the water inlet pipe 105. The sewage in the sewage bucket 102 is first filtered by the filter plate 109 and then flows downward, so that the sewage flowing downward can drive the rotating blade 108 to rotate after contacting the rotating blade 108 on the surface of the transmission rod 107, thereby making the rotating blade 108 drive the transmission rod 107 to rotate. At the same time, the user can install a driving motor A on the inner side of the liquid storage tank 202, so that the driving motor A can directly drive the first elliptical wheel 201 and drive the transmission rod 107 to rotate, thereby avoiding the phenomenon that the rotating blade 108 cannot rotate when the amount of sewage is small, and can increase the adaptability of the use of the transmission rod 107.

[0047] After the transmission rod 107 rotates, it can drive the first elliptical wheel 201 to rotate, and the first spring 204f4 on the fixed plate 204f1 cooperates with the telescopic rod 204f2 to drive the connecting plate 204f3 to move inward, so that the connecting plate 204f3 drives the movable plate 204a on the top of the sealing plate 204c to move inward, so that the movable plate 204a moves inward and is always in contact with the first elliptical wheel 201, so that the first elliptical wheel 201 can drive the movable plate 204a to reciprocate. At the same time, the second spring 205i inside the air box 205d can drive the piston plate 205b to move inward through its own elastic force, so that the piston plate 205b can drive the push plate 205a to move inward, so that the push plate 205a is always in contact with the first elliptical wheel 201, so that after the first elliptical wheel 201 rotates, it can drive the push plate 205a to reciprocate.

[0048] When the movable plate 204a contacts the flat part of the first elliptical wheel 201, the liquid storage tank 204b on the movable plate 204a is located at the bottom of the liquid outlet pipe 203, so that the flocculant inside the liquid storage box 202 can be injected into the liquid storage tank 204b through the liquid outlet pipe 203. At this time, the sealing plate 204c at the bottom of the movable plate 204a can seal the bottom of the liquid storage tank 204b. With the rotation of the first elliptical wheel 201, the movable plate 204a can be driven to move outward on the sealing plate 204c, so that the movable plate 204a can drive the flocculant inside the liquid storage tank 204b to move outward. At this time, the liquid storage tank 204b is staggered with the liquid outlet pipe 203, so that the movable plate 204a seals the liquid outlet pipe 203. With the rotation of the first elliptical wheel 201, the movable plate 204a will gradually drive The liquid storage tank 204b is connected with the Z-shaped tube 204d, so that the flocculant inside the liquid storage tank 204b can be injected into the Z-shaped tube 204d, and the flocculant injected into the Z-shaped tube 204d can be injected into the connecting tube 206 through the first one-way valve 204e at the bottom of the Z-shaped tube 204d, and injected into the sewage treatment tank 101 through the connecting tube 206. When the movable plate 204a moves inward, it can drive the liquid storage tank 204b to be connected with the liquid outlet pipe 203 again, so that the flocculant inside the liquid storage tank 202 can be injected into the liquid storage tank 204b again. With the reciprocating movement of the movable plate 204a, the flocculant inside the liquid storage tank 204b can be quantitatively injected into the connecting tube 206 again (the frequency of flocculant addition can be adjusted according to the rotation speed of the transmission rod 107).

[0049] As the first elliptical wheel 201 rotates, the push plate 205a can be driven to move outward, so that after the push plate 205a moves outward, it can drive the piston plate 205b to move outward inside the air box 205d, so that the piston plate 205b pushes the air inside the air box 205d outward. At this time, the air pressure inside the air box 205d increases. As the air pressure inside the air box 205d increases, the sealing rubber plate 205f inside the air box 205d can be pushed outward and the second spring 205i is compressed, so that the sealing rubber plate 205f can fit with the air inlet 205e, so that the gas inside the air box 205d can only be injected into the outlet pipe 205g, and the gas is injected into the connecting pipe 206 through the second one-way valve 205h at the bottom of the outlet pipe 205g, so that the gas is injected into the connecting pipe 206. After connecting the pipe 206, the connecting pipe 206 can be pressurized, so that the flocculant remaining in the connecting pipe 206 will be gradually injected into the sewage treatment tank 101 as the air pressure in the connecting pipe 206 increases. At the same time, the gas can be injected into the sewage treatment tank 101 through the connecting pipe 206 to increase the mixing effect of the sewage. When the second spring 205i drives the piston plate 205b to move inward through its own elastic force, the inside of the air box 205d is in a negative pressure state. At this time, the outside air will push the sealing rubber plate 205f through the air inlet 205e and enter the inside of the air box 205d. As the piston plate 205b reciprocates, the outside air can be continuously injected into the connecting pipe 206 (the frequency of the gas entering the connecting pipe 206 can be adjusted according to the rotation speed of the transmission rod 107).

[0050] It should be noted that the drive motor A can be installed according to actual conditions.

The ventilation pipe 302h is connected with the air inlet groove 306. The bottom of the mounting tube 302c is fixedly connected with a limiting component 302i.

[0054] The limiting component 302i includes a limiting block 302i1, and limiting grooves 302i2 are provided on both sides of the bottom of the inner wall of the sewage treatment box 101, and the limiting block 302i1 is movably connected to the limiting groove 302i2.

[0055] The crushing assembly 305 includes a fixed frame 305a, which is fixedly connected to the top of the annular tube 303. The top of the fixed frame 305a is provided with a plurality of equidistantly distributed in a ring shape. The top of the fixed frame 305a is fixedly connected to a crushing cylinder 305b. The interior of the crushing cylinder 305b is fixedly connected to a movable frame 305c. The bottom of the movable frame 305c is movably connected to a crushing blade 305d. The crushing blade 305d is located at the top of the gas outlet nozzle 304.

[0056] The cleaning assembly 308 includes a third spring 308a, the top of the third spring 308a is fixedly connected to a fixing ring 308b, the inside of the fixing ring 308b is fixedly connected to a knocking block 308c, the bottom of the knocking block 308c is movably connected to the filter 307, the top of the knocking block 308c is fixedly connected to a guide protrusion 308d, and there are several guide protrusions 308d arranged and distributed in a ring shape with equal distances, the bottom of the second elliptical wheel 301 is fixedly connected to a rotating rod 308e, the bottom end of the rotating rod 308e passes through the inside of the air inlet groove 306, the bottom end of the rotating rod 308e is fixedly connected to a guide rod 308f, and there are several guide rods 308f arranged and distributed at equal distances, the guide rod 308f is movably connected to the guide protrusion 308d, the bottom end of the rotating rod 308e is fixedly connected to a limiting rod 308g, the bottom end of the limiting rod 308g passes through the inside of the knocking block 308c and is movably connected to the knocking block 308c.

[0057] Specifically, the rotation of the second elliptical wheel 301 can drive the transmission pin 302b to move through the elliptical annular groove 302a, so that the transmission pin 302b can drive the installation cylinder 302c to move, and the limiting block 302i1 inside the limiting groove 302i2 can limit the installation cylinder 302c, so that the transmission pin 302b can drive the installation cylinder 302c to move laterally, so that the installation cylinder 302c can squeeze or stretch the first telescopic hose 302f and the second telescopic hose 302g, so that the outside air is injected into the sewage treatment tank 101 through the air outlet nozzle 304 on the annular tube 303, so that the air can be mixed with the sewage after being injected into the sewage treatment tank 101.

[0058] When air is injected into the sewage treatment tank 101 through the air outlet nozzle 304, air will form bubbles in the sewage. During the rising process of the bubbles, they will enter the crushing cylinder 305b on the fixed frame 305a and contact the crushing blades 305d at the bottom of the movable frame 305c inside the crushing cylinder 305b, so that the crushing blades 305d can further crush the bubbles, making the bubbles denser, so that the denser bubbles can increase the effect of sewage mixing.

[0059] When the second elliptical wheel 301 rotates, it can drive the guide rod 308f to rotate. At the same time, the third spring 308a can drive the fixing ring 308b and the knocking block 308c to move upward through its own elastic force, so that the guide protrusion 308d on the knocking block 308c is fitted with the guide rod 308f, so that when the guide rod 308f rotates and contacts with the guide protrusion 308d, the knocking block 308c moves up and down to knock on the filter 307, so that the dust on the filter 307 can fall off the filter 307, thereby cleaning the filter 307.

[0060] Furthermore, when the transmission rod 107 drives the first elliptical wheel 201 to rotate, it will also drive the second elliptical wheel 301 to rotate. As the second elliptical wheel 301 rotates, the transmission pin 302b on the mounting cylinder 302c can be driven to move through the elliptical ring groove 302a, and the mounting cylinder 302c is limited by the internal limit block 302i1 of the limit groove 302i2, so that after the elliptical ring groove 302a rotates, it will drive the transmission pin 302b to move reciprocatingly horizontally.

[0061] When the installation cylinder 302c moves inward, it will squeeze the second telescopic hose 302g and stretch the first telescopic hose 302f. As the first telescopic hose 302f is stretched, the air pressure inside will gradually decrease, so that the air inside the air inlet groove 306 enters the second telescopic hose 302g through the vent pipe 302h. At the same time, the air inside the second telescopic hose 302g enters the first telescopic hose 302f through the air hole 302d on the installation cylinder 302c. As the second elliptical wheel 301 rotates, the transmission pin 302b can drive the installation cylinder 302c to move outward, so that the installation cylinder 302c compresses the first telescopic hose 302f and stretches the second telescopic hose 302g, so that the first telescopic hose 302f is squeezed. The internal air pressure will gradually increase, and at this time the air pressure will push the airtight pad 302e to fit tightly with the mounting tube 302c, thereby sealing the air hole 302d, so that the compressed gas of the first telescopic hose 302f will be injected into the annular tube 303, so that the gas is ejected through the air outlet nozzle 304 on the annular tube 303, so that after the gas is injected into the sewage treatment tank 101, the sewage and the flocculant can be fully mixed. When the second telescopic hose 302g is stretched, the air in the air inlet groove 306 will enter the second telescopic hose 302g through the vent pipe 302h, so that the second elliptical wheel 301 can rotate to continuously inject air into the sewage treatment tank 101 (and the frequency of air injection can be adjusted according to the rotation speed of the transmission rod 107). When gas is injected into the sewage treatment tank 101 through the gas outlet nozzle 304, bubbles will be formed. As the bubbles rise, they will enter the crushing cylinder 305b on the top of the fixed frame 305a, so that the bubbles entering the crushing cylinder 305b will contact the crushing blades 305d at the bottom of the movable frame 305c, thereby causing the crushing blades 305d at the bottom of the movable frame 305c to rotate. After the crushing blades 305d rotate, the bubbles can be further crushed, making the bubbles denser, thereby increasing the contact area between the bubbles and the sewage, and effectively increasing the mixing effect on the sewage.

[0062] When the outside air enters the air inlet groove 306, it will be filtered by the filter 307. At the same time, the rotation of the second elliptical wheel 301 will drive the rotating rod 308e to rotate, so that when the rotating rod 308e rotates, it will drive the guide rod 308f to contact the guide protrusion 308d on the knocking block 308c. At the same time, the knocking block 308c will be moved upward by the elastic force of the third spring 308a at the bottom of the fixing ring 308b, so that the guide rod 308f can move up and down to knock the filter 307 after contacting the guide protrusion 308d, thereby generating vibration on the filter 307, so that the dust on the filter 307 can be separated from the filter 307, and then the filter 307 is cleaned.

[0063] After the sewage is flocculated by the flocculant, it will gradually pass through the sedimentation chamber and over the vertical plate 103, thereby entering the filter chamber formed between the vertical plate 103 and the partition 104, and be filtered by the filter layer inside the filter chamber (the sewage filter layer is a common sewage filter layer), and then discharged through the outlet valve 106 on the sewage treatment tank 101.

[0064] The remaining structure is the same as that of Example 2.

[0065] Reference Figures 1 to 8 , which is the fourth embodiment of the present invention, and this embodiment is different from the third embodiment in that: a sewage treatment device for sewage treatment.

[0066] The sewage is injected into the sewage bucket 102 inside the sewage treatment tank 101 through the water inlet pipe 105. The sewage in the sewage bucket 102 is first filtered by the filter plate 109 and then flows downward, so that the sewage flowing downward can drive the rotating blade 108 to rotate after contacting the rotating blade 108 on the surface of the transmission rod 107, so that the rotating blade 108 drives the transmission rod 107 to rotate, and the user can install the driving motor A on the inner side of the liquid storage tank 202, so that the driving motor A can directly drive the first elliptical wheel 201 and drive the transmission rod 107 to rotate, thereby avoiding the phenomenon that the rotating blade 108 cannot rotate when the amount of sewage is small, and can increase the adaptability of the use of the transmission rod 107.

[0067] After the transmission rod 107 rotates, it can drive the first elliptical wheel 201 to rotate, and the first spring 204f4 on the fixed plate 204f1 cooperates with the telescopic rod 204f2 to drive the connecting plate 204f3 to move inward, so that the connecting plate 204f3 drives the movable plate 204a on the top of the sealing plate 204c to move inward, so that the movable plate 204a moves inward and is always in contact with the first elliptical wheel 201, so that the first elliptical wheel 201 can drive the movable plate 204a to reciprocate. At the same time, the second spring 205i inside the air box 205d can drive the piston plate 205b to move inward through its own elastic force, so that the piston plate 205b can drive the push plate 205a to move inward, so that the push plate 205a is always in contact with the first elliptical wheel 201, so that after the first elliptical wheel 201 rotates, it can drive the push plate 205a to reciprocate.

[0068] When the movable plate 204a contacts the flat part of the first elliptical wheel 201, the liquid storage tank 204b on the movable plate 204a is located at the bottom of the liquid outlet pipe 203, so that the flocculant inside the liquid storage box 202 can be injected into the liquid storage tank 204b through the liquid outlet pipe 203. At this time, the sealing plate 204c at the bottom of the movable plate 204a can seal the bottom of the liquid storage tank 204b. With the rotation of the first elliptical wheel 201, the movable plate 204a can be driven to move outward on the sealing plate 204c, so that the movable plate 204a can drive the flocculant inside the liquid storage tank 204b to move outward. At this time, the liquid storage tank 204b is staggered with the liquid outlet pipe 203, so that the movable plate 204a seals the liquid outlet pipe 203. With the rotation of the first elliptical wheel 201, the movable plate 204a will gradually drive The liquid storage tank 204b is connected with the Z-shaped tube 204d, so that the flocculant inside the liquid storage tank 204b can be injected into the Z-shaped tube 204d, and the flocculant injected into the Z-shaped tube 204d can be injected into the connecting tube 206 through the first one-way valve 204e at the bottom of the Z-shaped tube 204d, and injected into the sewage treatment tank 101 through the connecting tube 206. When the movable plate 204a moves inward, it can drive the liquid storage tank 204b to be connected with the liquid outlet pipe 203 again, so that the flocculant inside the liquid storage tank 202 can be injected into the liquid storage tank 204b again. With the reciprocating movement of the movable plate 204a, the flocculant inside the liquid storage tank 204b can be quantitatively injected into the connecting tube 206 again (the frequency of flocculant addition can be adjusted according to the rotation speed of the transmission rod 107).

[0069] As the first elliptical wheel 201 rotates, the push plate 205a can be driven to move outward, so that after the push plate 205a moves outward, it can drive the piston plate 205b to move outward inside the air box 205d, so that the piston plate 205b pushes the air inside the air box 205d outward. At this time, the air pressure inside the air box 205d increases. As the air pressure inside the air box 205d increases, the sealing rubber plate 205f inside the air box 205d can be pushed outward and the second spring 205i is compressed, so that the sealing rubber plate 205f can fit with the air inlet 205e, so that the gas inside the air box 205d can only be injected into the outlet pipe 205g, and the gas is injected into the connecting pipe 206 through the second one-way valve 205h at the bottom of the outlet pipe 205g, so that the gas is injected into the connecting pipe 206. After connecting the pipe 206, the connecting pipe 206 can be pressurized, so that the flocculant remaining in the connecting pipe 206 will be gradually injected into the sewage treatment tank 101 as the air pressure in the connecting pipe 206 increases. At the same time, the gas can be injected into the sewage treatment tank 101 through the connecting pipe 206 to increase the mixing effect of the sewage. When the second spring 205i drives the piston plate 205b to move inward through its own elastic force, the inside of the air box 205d is in a negative pressure state. At this time, the outside air will push the sealing rubber plate 205f through the air inlet 205e and enter the inside of the air box 205d. As the piston plate 205b reciprocates, the outside air can be continuously injected into the connecting pipe 206 (the frequency of the gas entering the connecting pipe 206 can be adjusted according to the rotation speed of the transmission rod 107).

[0070] When the transmission rod 107 drives the first elliptical wheel 201 to rotate, it will also drive the second elliptical wheel 301 to rotate. As the second elliptical wheel 301 rotates, it can drive the transmission pin 302b on the mounting tube 302c to move through the elliptical ring groove 302a. The mounting tube 302c is limited by the internal limit block 302i1 of the limit groove 302i2, so that after the elliptical ring groove 302a rotates, it will drive the transmission pin 302b to move back and forth horizontally.

[0071] When the installation cylinder 302c moves inward, it will squeeze the second telescopic hose 302g and stretch the first telescopic hose 302f. As the first telescopic hose 302f is stretched, the air pressure inside will gradually decrease, so that the air inside the air inlet groove 306 enters the second telescopic hose 302g through the vent pipe 302h. At the same time, the air inside the second telescopic hose 302g enters the first telescopic hose 302f through the air hole 302d on the installation cylinder 302c. As the second elliptical wheel 301 rotates, the transmission pin 302b can drive the installation cylinder 302c to move outward, so that the installation cylinder 302c compresses the first telescopic hose 302f and stretches the second telescopic hose 302g, so that the first telescopic hose 302f is squeezed. The internal air pressure will gradually increase, and at this time the air pressure will push the airtight pad 302e to fit tightly with the mounting tube 302c, thereby sealing the air hole 302d, so that the compressed gas of the first telescopic hose 302f will be injected into the annular tube 303, so that the gas is ejected through the air outlet nozzle 304 on the annular tube 303, so that after the gas is injected into the sewage treatment tank 101, the sewage and the flocculant can be fully mixed. When the second telescopic hose 302g is stretched, the air in the air inlet groove 306 will enter the second telescopic hose 302g through the vent pipe 302h, so that the second elliptical wheel 301 can rotate to continuously inject air into the sewage treatment tank 101 (and the frequency of air injection can be adjusted according to the rotation speed of the transmission rod 107). When gas is injected into the sewage treatment tank 101 through the gas outlet nozzle 304, bubbles will be formed. As the bubbles rise, they will enter the crushing cylinder 305b on the top of the fixed frame 305a, so that the bubbles entering the crushing cylinder 305b will contact the crushing blades 305d at the bottom of the movable frame 305c, thereby causing the crushing blades 305d at the bottom of the movable frame 305c to rotate. After the crushing blades 305d rotate, the bubbles can be further crushed, making the bubbles denser, thereby increasing the contact area between the bubbles and the sewage, and effectively increasing the mixing effect on the sewage.

[0072] When the outside air enters the air inlet groove 306, it will be filtered by the filter 307. At the same time, the rotation of the second elliptical wheel 301 will drive the rotating rod 308e to rotate, so that when the rotating rod 308e rotates, it will drive the guide rod 308f to contact the guide protrusion 308d on the knocking block 308c. At the same time, the knocking block 308c will be moved upward by the elastic force of the third spring 308a at the bottom of the fixing ring 308b, so that the guide rod 308f can move up and down to knock the filter 307 after contacting the guide protrusion 308d, thereby generating vibration on the filter 307, so that the dust on the filter 307 can be separated from the filter 307, and then the filter 307 is cleaned.

[0073] After the sewage is flocculated by the flocculant, it will gradually pass through the sedimentation chamber and cross the vertical plate 103, and then enter the filter chamber formed between the vertical plate 103 and the partition 104, and be filtered by the filter layer inside the filter chamber. The sewage filter layer is a common sewage filter layer, and then it is discharged through the outlet valve 106 on the sewage treatment tank 101.

[0074] In summary, the transmission rod 107 is used to drive the first elliptical wheel 201 inside the quantitative adding mechanism 200 and the second elliptical wheel 301 inside the gas injection and mixing mechanism 300, so that the first elliptical wheel 201 can drive the quantitative component 204 to quantitatively add flocculant to the sewage treatment tank 101, and the second elliptical wheel 301 can drive the gas injection component 302 to inject gas and mix the sewage treatment tank 101.
