Description

Technical Field

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

[0002] As we all know, with the development of social economy, environmental governance plays an increasingly important role in people's lives. In the process of governance, sewage needs to be treated. The existing sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc. Sewage treatment is the process of treating sewage to meet the water quality requirements so that it can be discharged into a certain water body or reused.

[0003] After searching, a Chinese patent disclosed a sewage treatment device used for water environment management, and its application publication number is CN113582359A. The patent sets a slag discharge component inside the device, which has the advantages of monitoring water quality, notifying maintenance personnel in time, and repairing the device.

[0004] Although the above patent has the advantage of water quality monitoring, the entire treatment process lacks targeted treatment methods for specific types of pollutants. Heavy metal ions are difficult to be effectively removed by existing steps alone. Stirring sedimentation relies on alum to form flocs to precipitate impurities and cannot effectively react with heavy metal ions. Although activated carbon has certain adsorption properties, its adsorption effect on heavy metals is limited, and the four-layer water filter plate combination is not specially treated for heavy metals. The disinfection step is completely ineffective against heavy metals. The reverse osmosis membrane in the purification box can hardly guarantee complete interception of heavy metal ions, resulting in the risk of excessive heavy metals in the treated sewage. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a sewage treatment device for environmental governance, which has the effect of treating heavy metal ions contained in sewage, and is designed with a zoning treatment method, which can be used for preliminary sewage treatment, such as performing some conventional flocculation and precipitation reactions, while more refined treatment can be performed inside, and deep treatment of heavy metal ions can be performed. The zoning treatment method has the advantages of improving the targetedness and efficiency of the treatment.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A sewage treatment device for environmental management, comprising a fixed bracket, a treatment structure is bolted to the bottom of the fixed bracket, a driving motor is bolted to the top of the fixed bracket, a stirring structure is bolted to the bottom of the driving motor, the stirring structure is inside the treatment structure, storage boxes are bolted to both sides of the bottom of the fixed bracket, and the storage box is used in conjunction with the stirring structure;

[0007] The processing structure includes an outer cylinder and an inner cylinder, and the inner cylinder is bolted inside the outer cylinder, the outer cylinder is bolted to a fixed bracket, a processing cavity is formed between the outer cylinder and the inner cylinder, a storage cylinder is bolted to the bottom of the outer cylinder, and a slag discharge mechanism is arranged inside the storage cylinder, and the top of the slag discharge mechanism is bolted to the inner cylinder;

[0008] The slag discharge mechanism includes a slag discharge seat, and the interior of the slag discharge seat is in contact with an opening and closing seat, a slag discharge component is arranged on the top of the opening and closing seat, and a diversion component is sleeved on the top of the surface of the slag discharge component, the surface of the diversion component is in contact with the inner wall of the storage cylinder, and the top of the diversion component is bolted to the internal cylinder.

[0009] By adopting the above technical scheme, a treatment structure is set up, and a treatment cavity is formed by the external cylinder and the internal cylinder of the treatment structure, so that zoning treatment can be achieved. The external cylinder can be used for preliminary sewage treatment, such as some conventional flocculation and sedimentation reactions; while the internal cylinder can be used for more refined treatment and deep treatment of heavy metal ions. The designed zoning treatment method improves the targetedness and efficiency of the treatment, and the integration of precipitation and slag discharge is realized through the coordinated use of the storage cylinder and the slag discharge mechanism. The sediment accumulates in the storage cylinder, and the slag discharge mechanism can automatically open and close the slag discharge channel according to the accumulation of the sediment, thereby ensuring the continuity of the treatment process and avoiding the interference of the sediment on the treatment process.

[0010] The present invention is further configured as follows: the diversion component includes a fixed shell, the top of the fixed shell is rotatably connected to a first movable ring, and the bottom of the first movable ring is bolted to a first gear ring, the right side of the first gear ring is meshedly connected to a first gear, the inside of the fixed shell is rotatably connected to a second movable ring, and the inner wall of the second movable ring is bolted to a connecting block, the bottom of the connecting block is bolted to a second gear ring, the left side of the second gear ring is meshedly connected to a second gear, the first movable ring and the second movable ring are both provided with a plurality of through holes in a ring shape, and the fixed shell is provided with connecting holes at positions corresponding to the through holes.

[0011] By adopting the above technical solution, a diversion component is set up. As the sediment inside the storage cylinder is deposited, the slag discharge component will rise together. When the slag discharge component rises to a certain level, a signal will be triggered. Therefore, the second gear is driven by an external driving device to drive the second gear ring to rotate, and the second movable ring is driven to rotate by the connecting block, so that the through hole inside the second gear ring is misaligned with the corresponding connecting hole, so that the sewage in the external cylinder is intercepted, and the external driving device such as a motor drives the first gear to drive the first gear ring and the first movable ring to rotate, so that the through hole inside the first gear ring is connected with the corresponding connecting hole. Therefore, the sewage in the external cylinder will enter the internal cylinder to remove heavy metal ions, thereby realizing the distribution of sewage in different areas and improving the targeted treatment effect. The shape and size of the through hole and the connecting hole can be flexibly adjusted according to needs.

[0012] The present invention is further configured as follows: the slag discharge assembly includes a movable column, and a float is slidably sleeved on the surface of the movable column, a float is sleeved on the surface of the float, a telescopic plate is rotatably connected to the bottom of the float, and the telescopic plate is rotatably connected to the opening and closing seat, a movable seat is sleeved on the top of the surface of the movable column, a fixed seat is bolted to the inside of the fixed shell, and the fixed seat is used in conjunction with the movable seat, a plurality of blocking blocks are welded on the top of the movable seat in a ring shape, and the blocking blocks are used in conjunction with the fixed seat, guide rods are bolted to both sides of the top of the slag discharge seat, and a trigger member is provided on the top of the guide rod, the floating plates are used in conjunction with the trigger member, the top of the movable column is bolted to a transfer plate, a sensing member is provided inside the fixed seat, and the sensing member is used in conjunction with the transfer plate.

[0013] By adopting the above technical solution, a slag discharge component is set. As the sediment accumulates in the storage cylinder, the float ball and the float plate will drive the movable column to rise, and the rise of the float plate will drive the opening and closing seat to release the seal on the slag discharge seat through the telescopic plate. Therefore, the sediment will be discharged from the storage cylinder, ensuring the effective volume in the storage cylinder. The movement of the movable column will simultaneously push the movable seat, the blocking block and the transfer plate to rise and move the movable seat and the blocking block to the inside of the fixed seat. The blocking block seals the hole in the fixed seat, so that when the sewage enters the internal cylinder, it will not enter the interior of the storage cylinder and affect the slag discharge work. When the float plate moves, it will contact the trigger member, causing the trigger member to The component triggers a signal to control the movement of the above-mentioned diversion component. In the slag discharge process, in order to ensure the flow of sewage into the internal cylinder, the slag discharge speed is slow. When the slag discharge is completed, the float and the float plate will drop under the action of gravity, so the block is separated from the fixed seat, and the transfer plate will contact the induction component to trigger the signal to open the through hole in the second movable ring, while the through hole in the first movable ring is closed, so that the external cylinder can enter the sewage for continuous treatment, and the interior of the float and the float are filled with a liquid larger than the water seal, so the sewage in the storage cylinder will not cause the float and the float to rise, which can ensure that the float and the float will rise only under the deposition of sediment.

[0014] The present invention is further configured as follows: a retaining ring is arranged on the surface of the fixed shell, and the retaining ring is arranged in an inverted cone shape as a whole, the upper part of the retaining ring is connected to the inner wall of the fixed shell, and a certain gap is arranged between the bottom of the retaining ring and the fixed shell.

[0015] By adopting the above technical solution, the retaining ring is set in an inverted cone shape, which helps to guide the particulate matter in the sewage to gather at the bottom of the fixed shell, avoiding the accumulation of particulate matter inside the fixed shell and affecting the normal operation of the diversion component. At the same time, the gap between the bottom of the retaining ring and the fixed shell allows sewage to pass through, reducing the passage of suspended matter in the sewage.

[0016] The present invention is further configured as follows: the trigger member includes a protective shell, the protective shell is arranged on the top of the guide rod, and the protective shell is bolted to the fixed shell on one side close to the guide rod, a moving rod is slidably arranged inside the protective shell, and the moving rod is slidably sleeved on the surface of the guide rod, a movable plate is bolted to the top of the movable plate, a moving contact is bolted to the top of the movable plate, a static contact is bolted to the top of the inner wall of the protective shell, and the static contact is used in conjunction with the moving contact, both sides of the movable plate are penetrated by limit rods, and the top and bottom of the limit rods are connected to the inner wall of the protective shell.

[0017] By adopting the above technical solution, a trigger is set, and the floating plate rises and contacts the movable plate, pushing the movable plate to move upward. The movable plate drives the movable rod to slide on the guide rod. At the same time, the moving contact on the movable plate contacts the static contact to form an electrical signal path, thereby controlling the opening and closing of the shunt component.

[0018] The present invention is further configured as follows: the opening and closing seat is configured in an inverted cone shape, and a slag discharge hole used in conjunction with the opening and closing seat is provided inside the slag discharge seat.

[0019] By adopting the above technical scheme, the opening and closing of the slag discharge can be effectively controlled by cooperating between the inverted cone-shaped opening and closing seat and the slag discharge hole of the slag discharge seat. When slag discharge is required, the opening and closing seat moves upward and the slag discharge hole opens; when slag discharge is not required, the opening and closing seat fits tightly with the slag discharge hole under gravity or other forces to prevent leakage of sediment.

[0020] The present invention is further configured as follows: the stirring structure includes a main shaft, the main shaft is bolted to the bottom of the driving motor, and the surface of the main shaft is sleeved with a connecting frame, the bottom of the connecting frame is bolted with a fixing rod, and the fixing rod is inside the processing cavity, the bottom between the inner cylinder and the outer cylinder on the opposite side is bolted with a supporting frame, the fixing rod is slidably arranged on the top of the supporting frame, the surface of the fixing rod is rotatably connected with a fixing ring through a bearing, and the surface of the fixing ring is annularly welded with a plurality of first stirring blades, a secondary shaft is arranged at the bottom of the main shaft, and the top and bottom of the secondary shaft surface are sleeved with a fixing frame, the fixing frame is bolted to the side close to the inner wall of the inner cylinder, the surface of the secondary shaft is sleeved with a plurality of second stirring blades distributed equidistantly, the top of the secondary shaft surface is slidably sleeved with a connecting mechanism, and the connecting mechanism is used in conjunction with the main shaft.

[0021] By adopting the above technical solution, a stirring structure is set up, and the main shaft is driven to rotate by a driving motor, and the main shaft drives the connecting frame and the fixed rod to rotate, so that the first stirring blade stirs the sewage in the treatment cavity, and at the same time, the fixed ring is connected to the fixed rod through a bearing sleeve. Therefore, when the fixed rod revolves, the first stirring blade will rotate at the same time to improve the mixing effect of the agent and sewage. Through the connecting mechanism, the secondary shaft can be disconnected or connected to the main shaft when the internal cylinder is treating or not treating sewage, thereby achieving energy saving effect, and the sewage in the internal cylinder is stirred by the second stirring blade on the secondary shaft to improve the sewage treatment effect.

[0022] The present invention is further configured as follows: the connecting mechanism includes a movable sleeve, the surface of the movable sleeve is rotatably connected to a positioning ring through a bearing, and electric cylinders are bolted to both sides of the bottom of the positioning ring, the bottom of the electric cylinder is bolted to a bottom fixing frame, the bottom of the main shaft is bolted to a fixing block, and the inner wall of the movable sleeve and the surface of the fixed block are respectively provided with a plurality of protrusions and grooves in a ring shape, and the protrusions and grooves are used in conjunction with each other.

[0023] By adopting the above technical solution and setting up a connecting mechanism, when sewage needs to be treated in the internal cylinder, the positioning ring and the movable sleeve can be driven to rise on the surface of the secondary shaft by the electric cylinder, so that the protrusion in the movable sleeve and the groove on the surface of the fixed block are connected to form an engaging state, thereby realizing the connection between the main shaft and the secondary shaft.

[0024] The present invention is further configured as follows: a connecting shaft is rotatably connected inside the storage box, and transmission wheels are sleeved on the surfaces of the connecting shaft and the main shaft, and a belt is wound between the insides of two adjacent transmission wheels.

[0025] By adopting the above technical solution, the storage box is connected to the main shaft through a connecting shaft, a transmission wheel and a transmission belt to realize power transmission. This connection method enables the stirring structure to drive the connecting shaft in the storage box to rotate while working, thereby facilitating the release of the medicines in the two storage boxes into the outer cylinder and the inner cylinder respectively.

[0026] The present invention is further configured as follows: a scraper is sleeved on the surface of the connecting shaft, and two baffles arranged in a V shape are bolted inside the storage box, a sealing plate is rotatably connected to the bottom of the baffle, and the sealing plate is used in conjunction with the scraper, and a discharge port is opened at the bottom of the storage box, and the discharge port is located between the two baffles.

[0027] By adopting the above technical solution, the scraper is driven to rotate through the connecting shaft, and the scraper scrapes the medicine accumulated in the storage box to the discharge port. When the scraper contacts the movable plate, it pushes the movable plate to rotate around its rotation axis, so that the medicine is discharged from the discharge port. After the discharge is completed, since the movable plate and the baffle are connected by a torsion spring, they are reset under the action of the torsion spring and the discharge port is closed, thereby achieving the effect of intermittent addition of medicine and improving the mixing effect between sewage and medicine.

[0028] Compared with the prior art, the present invention provides a sewage treatment device for environmental management, which has the following beneficial effects:

The designed zoned treatment method improves the pertinence and efficiency of the treatment, and the integration of precipitation and slag discharge is realized through the coordinated use of the storage cylinder and the slag discharge mechanism. The precipitate accumulates in the storage cylinder, and the slag discharge mechanism can automatically open and close the slag discharge channel according to the accumulation of the precipitate, so as to ensure the continuity of the treatment process and avoid the interference of the precipitate on the treatment process. The whole treatment structure is compact, and the treatment, precipitation and slag discharge functions are integrated in a relatively small space. Compared with some existing decentralized sewage treatment, the space utilization rate is greatly improved, which is particularly suitable for sewage treatment scenarios with limited space.

[0043] The slag discharge mechanism 6 includes a slag discharge seat 61, and the interior of the slag discharge seat 61 is in contact with an opening and closing seat 62, a slag discharge component 63 is arranged on the top of the opening and closing seat 62, and a diversion component 64 is sleeved on the top of the surface of the slag discharge component 63, the surface of the diversion component 64 is in contact with the inner wall of the storage cylinder 5, and the top of the diversion component 64 is bolted to the internal cylinder 4, and a treatment cavity is formed by the external cylinder 3 and the internal cylinder 4 of the treatment structure 2, so that zoning treatment can be realized. The external cylinder 3 can be used for preliminary sewage treatment, such as some conventional flocculation and sedimentation reactions; while the internal cylinder 4 can be used for more refined treatment, and deep treatment of heavy metal ions is carried out. The designed zoning treatment method improves the pertinence and efficiency of the treatment, and the storage cylinder 5 and the slag discharge mechanism 6 are used in combination to realize the integration of precipitation and slag discharge, and the sediment is accumulated in the storage cylinder 5. The slag discharge mechanism 6 can automatically open and close the slag discharge channel according to the accumulation of the sediment, so as to ensure the continuity of the treatment process and avoid the interference of the sediment on the treatment process.

[0044] The shunt assembly 64 comprises a fixed shell 641, the top of the fixed shell 641 is rotatably connected with a first movable ring 642, and the bottom of the first movable ring 642 is bolted with a first gear ring 643, the right side of the first gear ring 643 is meshedly connected with a first gear 644, the interior of the fixed shell 641 is rotatably connected with a second movable ring 645, and the inner wall of the second movable ring 645 is bolted with a connecting block 646, the bottom of the connecting block 646 is bolted with a second gear ring 647, and the left side of the second gear ring 647 is meshedly connected with a second gear 648, the interiors of the first movable ring 642 and the second movable ring 645 are both annularly provided with a plurality of through holes 649, and the fixed shell 641 is provided with connecting holes at positions corresponding to the through holes 649. By setting the shunt assembly 64, as the sediment inside the storage cylinder 5 is deposited, The slag discharge component 63 rises together, and when the slag discharge component 63 rises to a certain level, a signal will be triggered. Therefore, the second gear 648 is driven by an external driving device to drive the second gear ring 647 to rotate, and the second movable ring 645 is driven to rotate through the connecting block 646, so that the internal through hole 649 is misaligned with the corresponding connecting hole, so as to intercept the sewage in the external cylinder 3, and the external driving device such as a motor drives the first gear 644 to drive the first gear ring 643 and the first movable ring 642 to rotate, so that the internal through hole 649 is connected with the corresponding connecting hole. Therefore, the sewage in the external cylinder 3 will enter the internal cylinder 4 for the removal of heavy metal ions, thereby realizing the distribution of sewage in different areas and improving the targeted treatment effect. The shape and size of the through hole 649 and the connecting hole can be flexibly adjusted according to needs.

[0045] The slag discharge assembly 63 includes a movable column 631, and a floating ball 632 is slidably sleeved on the surface of the movable column 631, and a floating plate 633 is sleeved on the surface of the floating ball 632. The bottom of the floating plate 633 is rotatably connected with a telescopic plate 6310, and the telescopic plate 6310 is rotatably connected to the opening and closing seat 62. A movable seat 634 is sleeved on the top of the surface of the movable column 631, and a fixed seat 635 is bolted inside the fixed shell 641, and the fixed seat 635 is used in conjunction with the movable seat 634. A plurality of blocking blocks 636 are welded on the top of the movable seat 634 in a ring shape, and the blocking blocks 636 are used in conjunction with the fixed seat 635. The two sides of the top of the slag discharge seat 61 The guide rod 637 is bolted to each other, and a triggering member 638 is arranged on the top of the guide rod 637.

The interior of the fixed seat 635 is provided with a sensing member, and the sensing member is used in conjunction with the transfer plate 639. By setting the slag discharge assembly 63, as the sediment accumulates in the storage cylinder 5, the float 632 and the floating plate 633 will drive the movable column 631 to rise, and the rise of the floating plate 633 will drive the opening and closing seat 62 to release the seal of the slag discharge seat 61 through the telescopic plate 6310, so that the sediment will be discharged from the storage cylinder 5, ensuring the storage cylinder The effective volume in the body 5, and the movement of the movable column 631 will push the movable seat 634, the block 636 and the transfer plate 639 to rise and move the movable seat 634 and the block 636 to the inside of the fixed seat 635, and the block 636 seals the hole in the fixed seat 635, so that when the sewage enters the internal cylinder 4, it will not enter the interior of the storage cylinder 5 and affect the slag discharge work. When the floating plate 633 moves, it will contact the trigger member 638, so that the trigger member 638 triggers a signal, thereby controlling the movement of the above-mentioned diversion component 64.

When the slag discharge is completed, the float 632 and the float plate 633 will drop under the action of gravity, so the block 636 will separate from the fixed seat 635, and the transfer plate 639 will contact the sensor to trigger the signal to open the through hole 649 in the second movable ring 645, while the through hole 649 in the first movable ring 642 will be closed, so that the external cylinder 3 can enter the sewage for continuous treatment, and the interior of the float 632 and the float plate 633 is filled with a liquid larger than the water seal, so the sewage in the storage cylinder 5 will not cause the float 632 and the float plate 633 to rise, which can ensure that the float 632 and the float plate 633 will rise only under the deposition of sediment.

[0046] Among them, a retaining ring 10 is arranged on the surface of the fixed shell 641, and the retaining ring 10 is arranged in an inverted cone shape as a whole. The upper part of the retaining ring 10 is connected to the inner wall of the fixed shell 641, and a certain gap is arranged between the bottom of the retaining ring 10 and the fixed shell 641. The inverted cone shape of the retaining ring 10 helps to guide the particulate matter in the sewage to gather at the bottom of the fixed shell 641, avoiding the accumulation of particulate matter inside the fixed shell 641 and affecting the normal operation of the diversion component 64. At the same time, the gap between the bottom of the retaining ring 10 and the fixed shell 641 allows sewage to pass through, reducing the passage of suspended matter in the sewage.

[0047] The trigger member 638 includes a protective shell 638a, which is arranged on the top of the guide rod 637, and the side of the protective shell 638a close to the fixed shell 641 is bolted to it, a moving rod 638b is slidably arranged inside the protective shell 638a, and the moving rod 638b is slidably sleeved on the surface of the guide rod 637, a movable plate 638c is bolted on the top of the moving rod 638b, a moving contact 638d is bolted on the top of the movable plate 638c, and a static contact 638e is bolted on the top of the inner wall of the protective shell 638a, and the static contact 638e and the moving contact 638e are connected. 38d is used in conjunction with the movable plate 638c, and the limiting rods 638f are passed through both sides of the interior of the movable plate 638c, and the top and bottom of the limiting rods 638f are connected to the inner wall of the protective shell 638a. By setting the trigger member 638, the floating plate 633 rises and contacts the movable plate 638c, pushing the movable plate 638c to move upward, and the movable plate 638c drives the moving rod 638b to slide on the guide rod 637. At the same time, the moving contact 638d on the movable plate 638c contacts the static contact 638e to form an electrical signal path, thereby controlling the opening and closing of the shunt component 64.

[0048] Among them, the opening and closing seat 62 is set in an inverted cone shape, and the interior of the slag discharge seat 61 is provided with a slag discharge hole used in conjunction with the opening and closing seat 62. The inverted cone-shaped opening and closing seat 62 cooperates with the slag discharge hole of the slag discharge seat 61 to effectively control the opening and closing of the slag discharge. When slag discharge is required, the opening and closing seat 62 moves upward and the slag discharge hole opens; when slag discharge is not required, the opening and closing seat 62 fits tightly with the slag discharge hole under gravity or other forces to prevent sediment leakage.

[0049] Working principle of this embodiment: sewage first flows into the external cylinder 3, and in the treatment cavity, the stirring structure 8 stirs the sewage to fully mix the reagent and sewage, and performs conventional flocculation and sedimentation reactions, and the generated sediment passes through the second movable ring 645 and enters the storage cylinder 5. As the sediment accumulates in the storage cylinder 5, the float 632 and the floating plate 633 in the slag discharge assembly 63 rise due to the rise of the sediment, and the floating plate 633 drives the opening and closing seat 62 to move upward through the telescopic plate 6310, and the slag discharge hole of the slag discharge seat 61 is opened. The movable plate 638c of the trigger member 638 drives the movable rod 638b to slide on the guide rod 637, and the moving contact 638d contacts the static contact 638e to form an electrical signal, which is transmitted through the external drive device to drive the second gear 648 to drive the second gear ring 647 to rotate. The second movable ring 645 rotates accordingly, and the through hole 649 inside it is misaligned with the connecting hole of the fixed shell 641, thereby intercepting the sewage in the external cylinder 3. At the same time, the first gear 644 is driven to drive the first gear ring 643 and the first movable ring 642 to rotate, so that the through hole 649 of the first movable ring 642 is connected with the connecting hole, thereby guiding the sewage in the external cylinder 3 to enter the internal cylinder 4. After the slag discharge is completed, the floating ball 632 and the floating plate 633 descend under the action of gravity, the blocking block 636 is separated from the fixed seat 635, and the transfer plate 639 is connected to the fixed seat 635. The induction component contacts the trigger signal, causing the through hole 649 in the second movable ring 645 to open, and the through hole 649 in the first movable ring 642 to close, and the external cylinder 3 resumes receiving sewage for a new round of preliminary treatment, and this cycle is repeated to achieve continuous sewage treatment. After the sewage enters the internal cylinder 4, the sewage in the internal cylinder 4 is stirred by the stirring structure 8, so that the treatment agent for heavy metal ions is fully mixed with the sewage, and a deep removal precipitation reaction of the heavy metal ions is carried out. Finally, the sewage enters the subsequent equipment for other treatments.

By setting the stirring structure 8, the main shaft 81 is driven to rotate by the driving motor 7, and the main shaft 81 drives the connecting frame 82 and the fixed rod 83 to rotate, so that the first stirring blade 86 stirs the sewage in the treatment cavity. At the same time, the fixed ring 85 is sleeved on the fixed rod 83 through a bearing. Therefore, when the fixed rod 83 revolves, the first stirring blade 86 will rotate at the same time to improve the mixing effect of the agent and the sewage. Through the connecting mechanism 89, the secondary shaft 87 can be disconnected or connected to the main shaft 81 when the internal cylinder 4 is treating or not treating sewage, thereby achieving an energy-saving effect.
