Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment, in particular to surface wastewater treatment equipment with a sludge compression function. Background Art

[0002] Wastewater treatment equipment is a core component of modern environmental protection and public health systems. Its core purpose is to remove pollutants from domestic sewage, industrial wastewater, and agricultural runoff through physical, chemical, and biological methods, ensuring that treated water meets discharge standards or reuse requirements, thereby protecting the aquatic ecosystem and human health. With the acceleration of industrialization and urbanization, wastewater discharge volumes have increased dramatically and its composition has become increasingly complex, placing higher demands on treatment technologies. Traditional methods such as simple sedimentation and filtration are no longer sufficient, driving the continued development of efficient, integrated, and automated wastewater treatment equipment.

[0003] Modern wastewater treatment systems are often multi-stage, multi-process systems. Ceramic ultrafiltration membranes, a breakthrough in material filtration, offer excellent filtration efficiency for small-molecule contaminants in wastewater, along with advantages such as a long service life and stable filtration performance. However, their ability to handle sludge impurities in wastewater is limited. Excessive sludge adhesion can significantly degrade membrane filtration performance, and adding filters to filter out sludge also presents the technical challenge of sludge adhesion. Summary of the Invention

[0004] The object of the present invention is to provide a surface wastewater treatment device with a sludge compression function to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A surface wastewater treatment equipment with a sludge compression function includes a casing, a chassis, a mud removal mechanism, a separation mechanism, a short-line mechanism and a reverse osmosis membrane tube. The mud removal mechanism includes an assembly rack, an outer tube, a compression mechanism and a coagulation mechanism. The compression mechanism includes an inner sleeve. The coagulation mechanism also includes a reagent tank. The separation mechanism includes a three-way pipe and an infusion pipe. The short-line mechanism includes an inlet pool, a first pump pipe and a ceramic ultrafilter. The casing, the assembly rack, the reagent tank, the water inlet pool and the ceramic ultrafilter are all fixedly connected to the casing, the outer tube is fixedly connected to the first pump pipe, the three-way pipe is fixedly connected to the inner sleeve, the infusion pipe is fixedly connected to the three-way pipe and the ceramic ultrafilter, the reverse osmosis membrane tube is fixedly connected to the ceramic ultrafilter, and the casing is connected to the mud removal mechanism, the separation mechanism and the short-line mechanism through electrical signals.

[0006] The present invention performs rapid short-line filtration on wastewater by switching the filtration mode, passes surface wastewater into an inlet pool for static sedimentation, and preliminarily precipitates impurities in the wastewater, switches the filtration mode by detecting sludge impurities in the wastewater, and when the sludge content in the wastewater is still higher than a set standard value after static sedimentation, the chassis feeds back a control signal to the first pump pipe, and pumps the wastewater with excessive sludge content into an outer pipe through the first pump pipe, and a compression mechanism performs spiral stirring on the sewage flowing radially along the axis of the outer pipe in sections, so that the sludge-containing wastewater is in a vortex state, and a precipitation adhesive is uniformly injected into the wastewater vortex through a cohesion mechanism, so that the sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant, and the wastewater with sludge removed is passed into a ceramic ultrafilter through a separation mechanism, and small particle molecules in the wastewater are filtered to obtain clean water that meets the required standards, and when the sludge content in the wastewater is within the filtration range of the ceramic ultrafilter after static sedimentation, the wastewater is directly passed into the ceramic ultrafilter to complete filtration and output from the reverse osmosis membrane tube.

[0007] Furthermore, the mud removal mechanism also includes a recoil mechanism and a sealing sleeve, the compression mechanism also includes a segmented pipe, a drive motor and a rotating drum, the segmented pipe is provided with an assembly orifice plate, the recoil mechanism includes a first-stage filter disc, the inner sleeve, the assembly orifice plate, the first-stage filter disc, and the sealing sleeve are all fixedly connected to the outer pipe, the condensation mechanism also includes a high-pressure pump, a connecting pipe and an annular chamber, the outer pipe is provided with a side hole, the connecting pipe is fixedly connected to the side hole and the assembly orifice plate, the annular chamber is rotatably connected to the rotating drum, and the drive motor and the high-pressure pump are connected to the chassis through electrical signals.

[0008] When the sludge content in the wastewater is still higher than the set standard value after static sedimentation, the chassis feeds back the control signal to the first pump pipe, and the wastewater with excessive sludge content is pumped out to the outer pipe through the first pump pipe. The sludge wastewater is preliminarily filtered through the first-level filter disc of the backflushing mechanism, and then passes into the sealed space composed of the sealing sleeve, segmented pipe, rotating drum, and inner sleeve. The chassis feeds back the control signal to the drive motor and the high-pressure pump. The drive motor drives the rotating drum to rotate, and spirally stirs the sewage segmented flowing radially along the axis of the outer pipe, so that the sludge-containing wastewater is in a vortex state. The high-pressure pump evenly injects precipitation adhesive into the wastewater vortex, so that the sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant.

[0009] Furthermore, the compression mechanism also includes a multi-gear rod, the drive motor is fixedly connected to the inner sleeve, the output end of the drive motor is fixedly connected to the multi-gear rod, the segmented pipes and the rotating cylinder are provided with several groups, and the several groups of segmented pipes and rotating cylinders are linearly evenly distributed along the axis of the outer tube. The segmented pipes and the rotating cylinders are arranged crosswise, and adjacent rotating cylinders are in contact with each other. An outer gear ring is provided on the rotating cylinder, the multi-gear rod is engaged with the tooth surface of the outer gear ring, and the rotating cylinder is rotatably connected to the segmented pipe.

[0010] The driving motor outputs fixed-axis torque to the multi-gear rod, which engages with the tooth surface between the multi-gear rod and the outer gear ring on the rotor, and transmits the torque to the rotor. The surfaces of adjacent rotors are in contact, and the rotors rotate in adjacent cross-arranged segmented pipes to seal the axial channel formed by the rotors. Several groups of rotors linearly distributed along the axis of the outer pipe rotate coaxially and at the same speed, and spirally stir the sewage segments flowing radially along the axis of the outer pipe.

[0011] Furthermore, the rotating drum is also provided with eccentric circular holes and flow channels, and adjacent eccentric circular holes are arranged in a spiral line along the axis of the outer tube. The condensation mechanism also includes a one-way valve and a coater. The flow channels, one-way valves, and coaters are provided in several groups, and several groups of flow channels are evenly distributed along the circumference of the eccentric circular holes. The one-way valves and coaters are fixedly connected to the flow channels.

[0012] The drive motor drives several groups of rotating drums linearly and evenly distributed along the axis of the outer tube to rotate coaxially and at the same speed. Eccentric circular holes are provided in the rotating drums, with adjacent eccentric circular holes arranged helically along the axis of the outer tube. That is, the initial meshing positions of rotating drums of the same specifications and the multi-gear rod are different, resulting in deflection of the adjacent eccentric circular holes in the rotating drum cross section. The several groups of rotating drums rotate coaxially and at the same speed, rotating around the axis of the outer tube. The inner walls of the eccentric circular holes eccentrically rotate the sewage flowing radially along the axis of the outer tube, generating a centripetal force directed toward the axis of the outer tube on the cross section of the radially flowing sewage, causing sludge in the wastewater to gather toward the center. The adjacent eccentric circular holes in the rotating drums linearly and evenly distributed along the axis of the outer tube cause segmented eccentric rotation of the radially flowing wastewater, causing the radially flowing wastewater to form a long vortex. A cohesion mechanism evenly injects a precipitant into the eccentric circular holes through the flow channel. Under the action of the precipitant, the centripetal force of the vortex compresses the sludge, causing the sludge in the wastewater to be compressed into blocks by the precipitant.

[0013] Furthermore, the annular chamber is communicated with the flow channel, the communicating pipe is fixedly connected to the reagent tank and the annular chamber, and the high-pressure pump is fixedly connected to the reagent tank.

[0014] The high-pressure pump pumps the precipitant in the reagent tank into the annular chamber through the connecting pipe. The precipitant in the annular chamber passes through the one-way valve in the flow channel. Under the action of the coater, the precipitant is wrapped by the degradable membrane and passes into the eccentric circular hole. After adsorbing the sludge in the wastewater, the degradable membrane is hydrolyzed. The sludge in the wastewater is gathered under the action of the sedimentation agent, and the eddy centripetal force generated by the eccentric circular hole quickly compresses the sludge.

[0015] Furthermore, the recoil mechanism also includes a spring seat and a slide. The spring seat is fixedly connected to the first-level filter disc and the slide. The slide is provided with an arc plate and a striker. The spring seat, arc plate and striker are provided in several groups. Several groups of spring seats, arc plates and strikers are evenly distributed along the circumference of the first-level filter disc. The striker is provided on the side of the slide close to the first-level filter disc.

[0016] Wastewater with excessive sludge content is pumped out to the outer pipe through the first pump pipe. The sludge wastewater is initially filtered through the first-level filter disc, isolating larger impurities outside the first-level filter disc. The wastewater passing through the first-level filter disc impacts the arc plate, causing the slide to stretch the spring seat away from the first-level filter disc. When the filtration operation is completed and the pumping is stopped, the slide is reset under the action of the spring seat recovering the deformation, and the striker hits the first-level filter disc to prevent a large amount of impurities from adhering to the first-level filter disc, causing blockage and affecting the filtration efficiency.

[0017] Furthermore, the separation mechanism also includes a secondary filter disc, an electric control valve plate, a liquid pump and a discharge pipe. The secondary filter disc, the electric control valve plate, the infusion pipe and the discharge pipe are all fixedly connected to the three-way pipe, the liquid pump is fixedly connected to the infusion pipe, and the electric control valve plate and the liquid pump are all connected to the chassis through electrical signals.

[0018] The sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant and is sucked into the three-way pipe by the liquid pump. The agglomerated sludge is blocked by the secondary filter plate. The wastewater without sludge passes through the secondary filter plate and enters the ceramic ultrafilter through the infusion pipe. After the filtration is completed, the chassis feeds back the control signal to the electric control valve plate, and the electric control valve plate opens and the agglomerated sludge is discharged from the discharge pipe.

[0019] Furthermore, the short-line mechanism also includes a mud monitor and a second pump pipe. The mud monitor, the first pump pipe, and the second pump pipe are all fixedly connected to the water inlet pool. The second pump pipe is fixedly connected to the ceramic ultrafilter. The mud monitor, the first pump pipe, and the second pump pipe are all connected to the chassis through electrical signals.

[0020] The wastewater is allowed to settle in the inlet tank for preliminary precipitation. The sludge monitor detects the sludge impurity content in the wastewater. When the content is higher than the set standard value after settling, the chassis feeds back the control signal to the first pump pipe. The wastewater with excessive sludge content is pumped out through the first pump pipe to the compression mechanism and the separation mechanism and passed into the ceramic ultrafilter. The small particle molecules in the wastewater are filtered to obtain clean water that meets the required standards. When the sludge content in the wastewater is within the filtration range of the ceramic ultrafilter after settling, the wastewater is directly passed into the ceramic ultrafilter to complete the filtration and output from the reverse osmosis membrane tube.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a compression mechanism, which drives a plurality of groups of rotary drums linearly distributed along the axis of the outer tube to rotate coaxially and at the same speed through a driving motor, and an eccentric circular hole is provided in the rotary drum, and adjacent eccentric circular holes are arranged in a spiral line along the axis of the outer tube, that is, the initial meshing positions of rotary drums with the same specifications and the multi-gear rod are different, and adjacent eccentric circular holes produce deflection in the cross section of the rotary drum, and the plurality of rotary drums rotate coaxially and at the same speed, and the rotary drum rotates around the axis of the outer tube. The inner wall of the eccentric circular hole rotates eccentrically on the sewage flowing radially along the axis of the outer tube, and generates a centripetal force pointing to the axis of the outer tube on the cross section of the radially flowing sewage, so that the sludge in the wastewater gathers toward the center, and performs segmented eccentric rotation on the radially flowing wastewater, so that the radially flowing wastewater presents a long vortex shape, and the precipitant is pumped into the annular chamber through the connecting pipe, and the precipitant in the annular chamber passes through the one-way valve in the flow channel. Under the action of the coating device, the precipitant is wrapped by a degradable film and passes into the eccentric circular hole, After adsorbing the sludge in the wastewater, the degradable membrane is hydrolyzed, and the sludge in the wastewater gathers under the action of the sedimentation agent, and is compressed by the centripetal force of the vortex under the action of the precipitant. The sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant, which greatly improves the efficiency of sludge compression and filtration in the wastewater; the present invention designs a short-line mechanism, and the wastewater is allowed to stand in the water inlet tank for preliminary precipitation. The mud monitor detects the sludge impurity content in the wastewater. If the sludge content is higher than the set standard value, the wastewater is pumped out through the first pump pipe to the compression mechanism and the separation mechanism and passed into the ceramic ultrafilter, and the small particle molecules in the wastewater are filtered to obtain clean water that meets the required standards. If the sludge content is within the filtration range of the ceramic ultrafilter, the wastewater is directly passed into the ceramic ultrafilter to complete the filtration and be output by the reverse osmosis membrane tube; the present invention monitors the sludge content in the wastewater, switches the double short-line working mode according to the sludge content in the wastewater, and cooperates with the mud removal mechanism to quickly compress the sludge and the ceramic ultrafilter, which greatly improves the wastewater purification effect and wastewater treatment efficiency.

[0026] The present invention performs rapid short-line filtration of wastewater by switching the filtration mode, passes surface wastewater into the water inlet pool 51 for static sedimentation, and initially precipitates impurities in the wastewater. The filtration mode is switched by detecting sludge impurities in the wastewater. When the sludge content in the wastewater is still higher than the set standard value after static sedimentation, the chassis 2 feeds back a control signal to the first pump pipe 53, and the wastewater with excessive sludge content is pumped out to the outer pipe 32 through the first pump pipe 53. The compression mechanism 33 performs spiral stirring on the sewage flowing radially along the axis of the outer pipe 32. , making the wastewater containing sludge in a vortex state, and uniformly injecting precipitation adhesive into the wastewater vortex through the coagulation mechanism 34, so that the sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant, and the wastewater without sludge is passed into the ceramic ultrafilter 55 through the separation mechanism 4, filtering the small particle molecules in the wastewater to obtain clean water that meets the required standards. When the sludge content in the wastewater is within the filtration range of the ceramic ultrafilter 55 after static sedimentation, the wastewater is directly passed into the ceramic ultrafilter 55 to complete the filtration and is output by the reverse osmosis membrane tube 6.

[0027] like Figure 2 、 Figure 3 、 Figure 7 As shown, the mud removal mechanism 3 also includes a recoil mechanism 35 and a sealing sleeve 36, the compression mechanism 33 also includes a segmented pipe 332, a drive motor 333 and a rotating drum 335, the segmented pipe 332 is provided with an assembly orifice plate 3321, the recoil mechanism 35 includes a primary filter disc 351, the inner sleeve 331, the assembly orifice plate 3321, the primary filter disc 351, and the sealing sleeve 36 are all fixedly connected to the outer pipe 32, the condensation mechanism 34 also includes a high-pressure pump 342, a connecting pipe 343 and an annular chamber 344, the outer pipe 32 is provided with a side hole 321, the connecting pipe 343 is fixedly connected to the side hole 321 and the assembly orifice plate 3321, the annular chamber 344 is rotatably connected to the rotating drum 335, and the drive motor 333 and the high-pressure pump 342 are connected to the chassis 2 through electrical signals.

[0028] When the sludge content in the wastewater is still higher than the set standard value after static sedimentation, the chassis 2 feeds back a control signal to the first pump pipe 53, and the wastewater with excessive sludge content is pumped out to the outer pipe 32 through the first pump pipe 53. The sludge wastewater is preliminarily filtered through the first-stage filter disc 351 of the backflushing mechanism 35, and then passes into the sealed space composed of the sealing sleeve 36, the segmented pipe 332, the rotating drum 335, and the inner sleeve 331. The chassis 2 feeds back a control signal to the drive motor 333 and the high-pressure pump 342. The drive motor 333 drives the rotating drum 335 to rotate, and spirally stirs the sewage flowing radially along the axis of the outer pipe 32 in sections, so that the sludge-containing wastewater is in a vortex state. The high-pressure pump 342 evenly injects a precipitation adhesive into the wastewater vortex, so that the sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant.

[0029] like Figure 2 、 Figure 3As shown, the compression mechanism 33 also includes a multi-gear rod 334, the drive motor 333 is fixedly connected to the inner sleeve 331, and the output end of the drive motor 333 is fixedly connected to the multi-gear rod 334. The segmented tubes 332 and the rotating cylinders 335 are each provided with several groups, and the several groups of segmented tubes 332 and the rotating cylinders 335 are linearly evenly distributed along the axis of the outer tube 32. The segmented tubes 332 and the rotating cylinders 335 are arranged crosswise, and adjacent rotating cylinders 335 are in contact with each other. An outer gear ring 3351 is provided on the rotating cylinder 335, and the multi-gear rod 334 is engaged with the tooth surface of the outer gear ring 3351, and the rotating cylinder 335 is rotatably connected to the segmented tube 332.

[0030] The driving motor 333 outputs a fixed-axis torque to the multi-gear rod 334, which transmits the torque to the rotating drum 335 through the meshing of the tooth surfaces between the multi-gear rod 334 and the outer gear ring 3351 on the rotating drum 335. The surfaces of adjacent rotating drums 335 are in contact, and the rotating drums 335 rotate in the adjacent cross-arranged segmented pipes 332 to seal the axial channel formed by the rotating drums 335. Several groups of rotating drums 335 linearly distributed along the axis of the outer tube 32 rotate coaxially and at the same speed, and spirally stir the sewage segments flowing radially along the axis of the outer tube 32.

[0031] like Figure 4 、 Figure 5 As shown, the rotating drum 335 is also provided with an eccentric circular hole 3352 and a flow channel 3353, and adjacent eccentric circular holes 3352 are arranged in a spiral line along the axis of the outer tube 32. The condensation mechanism 34 also includes a one-way valve 345 and a coater 346. The flow channel 3353, the one-way valve 345, and the coater 346 are provided in several groups, and several groups of flow channels 3353 are evenly distributed along the circumference of the eccentric circular hole 3352. The one-way valve 345 and the coater 346 are fixedly connected to the flow channel 3353.

[0032] The driving motor 333 drives several groups of rotating drums 335 linearly distributed along the axis of the outer tube 32 to rotate coaxially and at the same speed. The rotating drum 335 is provided with eccentric circular holes 3352. Adjacent eccentric circular holes 3352 are arranged in a spiral line along the axis of the outer tube 32. That is, the initial meshing positions of rotating drums 335 of the same specifications and the multi-gear rod 334 are different. Adjacent eccentric circular holes 3352 produce deflection in the cross section of the rotating drum 335. Several groups of rotating drums 335 rotate coaxially and at the same speed. The rotating drum 335 rotates around the axis of the outer tube 32. The inner wall of the eccentric circular hole 3352 rotates eccentrically on the sewage flowing radially along the axis of the outer tube 32, and the cross section of the radially flowing sewage is deflected. A centripetal force pointing to the axis of the outer tube 32 is generated on the surface, causing the sludge in the wastewater to gather toward the center. Through several groups of adjacent eccentric circular holes 3352 in the rotating drum 335 that are linearly evenly distributed along the axis of the outer tube 32, the radially flowing wastewater is subjected to segmented eccentric rotation, causing the radially flowing wastewater to present a long-line vortex shape. The cohesion mechanism 34 evenly injects precipitant into the eccentric circular holes 3352 through the flow channel 3353. Under the action of the precipitant, the centripetal force of the vortex compresses the sludge, so that the sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant.

[0033] like Figure 2 、 Figure 5 、 Figure 6 As shown, the annular chamber 344 is connected to the flow channel 3353 , the connecting pipe 343 is fixedly connected to the reagent tank 341 and the annular chamber 344 , and the high-pressure pump 342 is fixedly connected to the reagent tank 341 .

[0034] The high-pressure pump 342 pumps the precipitant in the reagent tank 341 into the annular chamber 344 through the connecting pipe 343. The precipitant in the annular chamber 344 passes through the one-way valve 345 in the flow channel 3353. The precipitant is wrapped by the degradable film under the action of the coater 346 and passes into the eccentric circular hole 3352. After adsorbing the sludge in the wastewater, the degradable membrane is hydrolyzed, and the sludge in the wastewater is gathered under the action of the sedimentation agent, and the eddy centripetal force generated by the eccentric circular hole 3352 quickly compresses the sludge.

[0035] like Figure 7 As shown, the recoil mechanism 35 also includes a spring seat 352 and a slide 353. The spring seat 352 is fixedly connected to the first-level filter disc 351 and the slide 353. The slide 353 is provided with an arc plate 3531 and a striker 3532. The spring seat 352, the arc plate 3531, and the striker 3532 are provided in several groups. The several groups of spring seats 352, arc plates 3531, and strikers 3532 are evenly distributed along the circumference of the first-level filter disc 351. The striker 3532 is provided on the side of the slide 353 close to the first-level filter disc 351.

[0036] Wastewater with excessive sludge content is pumped out to the outer pipe 32 through the first pump pipe 53. The sludge wastewater is preliminarily filtered through the first-level filter disc 351, isolating larger impurities outside the first-level filter disc 351. The wastewater passing through the first-level filter disc 351 impacts the arc plate 3531, causing the slide 353 to stretch the spring seat 352 away from the first-level filter disc 351. When the filtration operation is completed and the pumping is stopped, the slide 353 is reset under the action of the spring seat 352 recovering its deformation, and the striker 3532 hits the first-level filter disc 351 to prevent a large amount of impurities from adhering to the first-level filter disc 351, causing blockage and affecting the filtration efficiency.

[0037] like Figure 8 As shown, the separation mechanism 4 also includes a secondary filter disc 42, an electric control valve plate 43, a liquid pump 45 and a discharge pipe 46. The secondary filter disc 42, the electric control valve plate 43, the infusion pipe 44 and the discharge pipe 46 are all fixedly connected to the three-way pipe 41, the liquid pump 45 is fixedly connected to the infusion pipe 44, and the electric control valve plate 43 and the liquid pump 45 are all connected to the chassis 2 through electrical signals.

[0038] The sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant and is sucked into the three-way pipe 41 by the liquid pump 45. The agglomerated sludge is blocked by the secondary filter plate 42. The wastewater without sludge passes through the secondary filter plate 42 and enters the ceramic ultrafilter 55 through the infusion pipe 44. After the filtration is completed, the chassis 2 feeds back a control signal to the electric control valve plate 43, and the electric control valve plate 43 opens and the agglomerated sludge is discharged from the discharge pipe 46.

[0039] like Figure 9 As shown, the short-line mechanism 5 also includes a mud monitor 52 and a second pump pipe 54. The mud monitor 52, the first pump pipe 53, and the second pump pipe 54 are all fixedly connected to the water inlet pool 51. The second pump pipe 54 is fixedly connected to the ceramic ultrafilter 55. The mud monitor 52, the first pump pipe 53, and the second pump pipe 54 are all connected to the chassis 2 through electrical signals.

[0040] The wastewater is allowed to settle in the water inlet tank 51 for preliminary precipitation, and the mud monitor 52 detects the sludge impurity content in the wastewater. When the content is higher than the set standard value after standing and settling, the chassis 2 feeds back a control signal to the first pump pipe 53. The wastewater with excessive sludge content is pumped out through the first pump pipe 53 to the compression mechanism 33 and the separation mechanism 4 and passed into the ceramic ultrafilter 55. The small particle molecules in the wastewater are filtered to obtain clean water that meets the required standards. When the sludge content in the wastewater is within the filtration range of the ceramic ultrafilter 55 after standing and settling, the wastewater is directly passed into the ceramic ultrafilter 55 to complete the filtration and output from the reverse osmosis membrane tube 6.

[0041] The working principle of the present invention is as follows: the wastewater is initially settled in the water inlet tank 51, and the sludge monitor 52 detects the impurity content of the sludge. When the sludge content is higher than the set standard value, the chassis 2 feeds back a control signal, and the wastewater is pumped out to the outer tube 32 through the first pump pipe 53. The sludge wastewater is initially filtered through the first filter plate 351. The driving motor 333 drives a plurality of groups of rotating drums 335 linearly distributed along the axis of the outer tube 32 to rotate coaxially and at the same speed. The eccentric circular hole 335 is provided in the rotating drum 335. 2. Adjacent eccentric circular holes 3352 are arranged in a spiral line along the axis of the outer tube 32, that is, the initial meshing positions of the same specification of the rotating drum 335 and the multi-gear rod 334 are different. The adjacent eccentric circular holes 3352 produce deflection in the cross section of the rotating drum 335. Several groups of rotating drums 335 rotate coaxially and at the same speed. The rotating drum 335 rotates around the axis of the outer tube 32. The inner wall of the eccentric circular hole 3352 rotates eccentrically on the sewage flowing radially along the axis of the outer tube 32, generating a deflection on the cross section of the radially flowing sewage. The centripetal force of the axis of the outer tube 32 causes the sludge in the wastewater to gather toward the center, and performs segmented eccentric rotation on the radially flowing wastewater, so that the radially flowing wastewater presents a long vortex shape. The precipitant is pumped into the annular chamber 344 through the connecting pipe 343. The precipitant in the annular chamber 344 passes through the one-way valve 345 in the flow channel 3353. The precipitant is wrapped by the degradable film under the action of the coating device 346 and passes into the eccentric circular hole 3352. After absorbing the sludge in the wastewater, the degradable film is hydrolyzed, and the wastewater is discharged. The sludge in the water gathers under the action of the precipitant and is compressed by the centripetal force of the vortex under the action of the precipitant. The sludge in the wastewater is compressed into blocks by the vortex under the action of the precipitant. The separation mechanism 4 quickly separates the sludge, and the wastewater is passed into the ceramic ultrafilter 55 to filter small particle molecules to obtain clean water that meets the required standards. When the sludge content in the wastewater is within the filtration range of the ceramic ultrafilter 55 after static sedimentation, the wastewater is directly passed into the ceramic ultrafilter 55 to complete the filtration and is output by the reverse osmosis membrane tube 6.
