Description

Technical Field

[0001] The present invention relates to the technical field of sewage purification and treatment, and specifically to a sewage purification and treatment device for environmental engineering. Background Art

[0002] The sewage purification and treatment device for environmental engineering is a series of devices used to treat sewage to meet the discharge standard or the reusable standard. It usually includes a grille for intercepting larger floating objects and sundries. The filtering grille consists of a group of parallel bars or meshes and is installed in the channel or pipeline through which the sewage flows. When the sewage passes through the grille, solid sundries with sizes larger than the gaps between the bars or the apertures of the mesh are intercepted on the grille, while the water flow can continue to flow through the gaps of the grille or the mesh holes, thus realizing solid-liquid separation. And it is driven by a motor to make the scraper or rake teeth move along the grille, scrape up the sundries and convey them to the discharge port above the grille, where they fall into the trash can or are conveyed to subsequent treatment facilities; a grit chamber to precipitate heavy particles such as sand grains in the water; a regulating tank for regulating the water volume and quality of the sewage to ensure the stable operation of the subsequent treatment process, adding a coagulant and a flocculant aid to make fine suspended particles coagulate into larger flocs, and then precipitate and separate in the sedimentation tank. The chemical dosing and regulating device is a device for adding chemical agents to the sewage system. It usually consists of parts such as a chemical agent storage system, a metering system, a control system, and an actuator. Adding a coagulant to the sewage, under the action of gravity, the flocs gradually precipitate to the bottom of the water to realize solid-liquid separation.

[0003] During the chemical dosing process, the coagulant is usually added to the sewage system quantitatively and regularly. However, this chemical dosing method is difficult to adapt to sudden changes in the sewage quality, is not easy to adjust the chemical dosing amount according to the changing state of the sewage pollution degree, cannot accurately dose according to the actual pollution degree, cannot make timely adjustments for quantitative and regular chemical dosing, and cannot quickly adapt to water quality fluctuations. This may lead to unreasonable resource allocation throughout the sewage treatment process. When the water quality is good, excessive chemical agent resources are invested, increasing the chemical agent cost and causing unnecessary waste; while when the water quality is poor, the chemical agent resources are relatively insufficient, resulting in unqualified effluent water quality, incomplete removal of pollutants such as suspended solids and colloids, affecting the treatment effect and stability of the entire sewage treatment system, unable to achieve optimal allocation of resources, making the sewage treatment system in a passive state, reducing the overall operation efficiency of the sewage treatment system, and reducing the adaptability and shock resistance of the system to different water quality conditions when industrial wastewater discharges abnormally, causing sudden increase or decrease in the pollutant concentration in the sewage. Therefore, we propose a sewage purification and treatment device for environmental engineering. Summary of the Invention

[0021] The present invention at least has the following beneficial effects:

[0022] The traditional fixed chemical dosing flow rate method may cause waste or shortage of chemicals due to fluctuations in the quality of sewage. Dynamically adjusting the chemical dosing flow rate according to the weight of plant debris can avoid unnecessary over-dosing of chemicals, reduce the usage amount of chemicals, thereby reducing the chemical procurement cost. While ensuring the treatment effect, it realizes the rational utilization of resources and cost control. A reasonable chemical dosing flow rate helps to maintain the normal operation of the sewage treatment equipment, enables the system to maintain a relatively stable treatment effect in the face of different water quality changes, avoids the imbalance of the treatment system caused by water quality fluctuations, enables the chemical dosing amount to match the pollutant content in the sewage, realizes precise chemical dosing, and avoids the problem of poor treatment effect caused by too much or too little chemical dosing, ensuring that the chemical agents can fully play their roles in the sewage treatment process, effectively removing harmful substances in the sewage, and improving the effluent water quality.

[0023] Precise chemical dosing can ensure that the pollutants in the sewage are effectively treated, make the effluent water quality more in line with the environmental protection discharge standards, reduce the excessive use of chemicals, and also helps to reduce the potential impact of chemical substances on the environment during the sewage treatment process, reflecting the concept of green environmental protection.

[0024] Adjusting the stirring speed according to the descending distance of the first elastic piece can make the stirring intensity adapt to the amount of debris and the reaction requirements of the chemicals. When there is more debris and more chemicals, the stirring speed is increased to strengthen the mixing reaction; otherwise, the stirring speed is decreased to avoid over-stirring. Over-stirring will cause strong turbulence in the water body, increase the internal friction of the water flow, and lead to energy loss of the water flow.

[0025] Moreover, it can accurately adjust the chemical dosage according to the actual weight of pollutants. Whether it is plants or sediment, when the amount of one of the pollutants increases, the chemical dosing system will correspondingly increase the chemical dosage. It determines the chemical dosing flow only based on the one with the greater weight value, without the need to consider the complex combinations of multiple pollutants simultaneously. It can quickly respond to the changes in the dominant pollutants in the sewage. When the weight of a certain pollutant increases significantly, the chemical dosing system can immediately adjust the chemical dosing flow according to this change, timely respond to sudden changes in water quality, avoid water quality deterioration caused by untimely treatment, ensure that the ratio of the chemical agent to pollutants always remains within an appropriate range, thereby improving the sewage treatment effect and ensuring that the effluent water quality meets the standards stably. It can simultaneously adapt to the treatment of sewage containing plants and sediment in different proportions. In actual sewage treatment scenarios, the types and contents of pollutants in the sewage will constantly change. This method can flexibly respond to various situations, is not affected by the changes of a single pollutant, and has stronger adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] A connecting component 2 is provided at the top of the operation box 13. The connecting component 2 includes a first rotating rod 21 connected to the connecting frame 14, and a first belt 22 is sleeved outside the first rotating rod 21. The upper end of the first belt 22 is sleeved outside a second rotating rod 23. One end of the second rotating rod 23 is fixedly connected to the output shaft of the second motor 24, and the other end of the second rotating rod 23 is rotatably connected to the inner wall of the protective shell 25. The lower end of the protective shell 25 is fixedly connected to the outer wall of the operation box 13. When the second motor 24 works, the second motor 24 drives the second rotating rod 23 to rotate. The rotation of the second rotating rod 23 drives the first rotating rod 21 to rotate through the first belt 22. The rotation of the first rotating rod 21 causes the grille frame 15 to rotate and move, intercepting the sundries in the sewage and lifting them to the upper part along with the rotation of the grille frame 15, realizing continuous sewage removal, greatly improving the efficiency of sundries cleaning, effectively preventing the sundries from accumulating in the water and causing blockage. Its grille bars are usually designed to be relatively dense, capable of intercepting sundries of various shapes and sizes, such as branches, having a high capture rate for the sundries in the sewage, effectively protecting the subsequent treatment equipment, and reducing equipment failures and wear caused by the entry of sundries.

[0050] The scraping component 3 includes scraping claws 31 pressing against the inner wall of the grille frame 15, and the scraping claws 31 are fixed to the outer wall of the third rotating rod 32. The end of the scraping claw 31 away from the third rotating rod 32 is set to be hook-shaped. The scraping claws 31 being set to be hook-shaped facilitates hooking out the sundries on the inner wall of the grille frame 15, realizing the cleaning operation of the sundries on the inner wall of the grille frame 15. The scraping claws 31 directly act on the grille surface, quickly and effectively scraping off various sundries intercepted on the grille, such as leaves, garbage, fibers, etc., avoiding the accumulation of sundries on the grille, ensuring the water passing capacity of the grille, maintaining the normal operation of the sewage treatment system, and timely scraping off the sundries can prevent them from accumulating in the grille gaps, avoiding the blockage of the grille caused by excessive sundries and thus affecting the smooth passage of sewage.

[0051] One end of the third rotating rod 32 is rotatably connected to the inner wall of the operation box 13, and a fourth rotating rod 33 is fixed to the other end of the third rotating rod 32. The end face of the fourth rotating rod 33 is rotatably connected to the inner wall of the protective shell 25. A second belt 34 is sleeved outside the fourth rotating rod 33, and the other end of the second belt 34 is sleeved outside the first rotating rod 21. One end of the first rotating rod 21 away from the connecting frame 14 is rotatably connected to the inner wall of the protective shell 25. The rotation of the first rotating rod 21 drives the fourth rotating rod 33 to rotate synchronously through the second belt 34, enabling the rotary movement of the grille frame 15 and the rotation of the scraping claws 31 to be synchronized. The moving frequencies of the grille frame 15 and the scraping claws 31 are the same, facilitating the scraping claws 31 to insert into the interior of the grille frame 15 and hook out the sundries in the inner wall.

[0052] A collection box 35 is arranged below the scraping claw 31, and sewage outlets 38 are formed on both sides of the collection box 35. A baffle 36 is inserted inside the sewage outlet 38. Guide shells 37 are fixed on both sides of the outer wall of the collection box 35. The sundries scraped by the scraping claw 31 fall into the collection box 35, realizing the temporary collection operation of the sundries, collecting the scraped sundries, preventing them from scattering or decaying around the grille 15, reducing the generation of peculiar smell and the breeding of mosquitoes and flies, improving the surrounding environmental conditions, being beneficial to maintaining environmental hygiene, collecting the sundries into the collection box 35, facilitating unified collection, and being convenient for subsequent classification, disposal or recycling of the sundries, meeting the requirements of environmental protection and resource recycling.

[0053] The monitoring component 4 includes a support plate 41 arranged inside the collection box 35. A connecting plate 42 is fixed to the bottom of the support plate 41. Springs 43 are fixed to both sides of the bottom of the connecting plate 42, and the bottoms of the springs 43 are fixed to the inner wall of the collection box 35. A connecting rod 44 is fixed to the bottom of the connecting plate 42, and a guide plate 45 is fixed to the bottom of the connecting rod 44. The end face of the guide plate 45 is connected to a connecting plate 46. The connecting plate 46 is connected to a first elastic piece 47. The first elastic piece 47 is slidably connected to the surface of a first sliding rheostat 48. The two ends of the first sliding rheostat 48 are fixed to the inner wall of the collection box 35. By monitoring the descending distance of the support plate 41, the weight of the sundries can be judged. During the process of the scraping claw 31 scraping up the sundries and transporting them to the support plate 41, the weight information of the sundries can be obtained in real time, without the need for manual frequent inspection or using other complex weighing equipment for regular measurement, and the change of the weight of the sundries can be reflected in a timely manner, providing timely data support for the adjustment of the subsequent chemical dosing flow rate. It belongs to non-contact measurement and will not cause additional interference or damage to the sundries or the collection system. Compared with the traditional direct weighing method, there is no need to install complex weighing sensors or other contact measurement devices on the collection plate, avoiding the adverse effects on the measurement equipment caused by the characteristics of the sundries such as moisture and corrosiveness, and improving the reliability and stability of the measurement. The guide plate 45 is set in a "V" shape. If fine liquid water drops move along the gap between the collection box 35 and the connecting rod 44 to the surface of the guide plate 45, the liquid water drops are guided by the guide plate 45 to drip at the bottom of the guide plate 45, avoiding the contact between the liquid water drops and the first elastic piece 47 and the first sliding rheostat 48, achieving the purpose of protecting the first elastic piece 47 and the first sliding rheostat 48.

[0054] A connecting plate three 51 is fixed on the surface of the connecting plate two 46, and a pressing block one 52 is fixed on the surface of the connecting plate three 51. The pressing block one 52 presses against the surface of the switch plate one 53. A pressing switch one 54, a pressing switch two 55 and a pressing switch three 56 are sequentially distributed on the surface of the switch plate one 53. Both sides of the pressing block one 52 are arc-shaped, which is convenient for the pressing block one 52 to press against the pressing switch one 54, the pressing switch two 55 and the pressing switch three 56. By the pressed states of the pressing switch one 54, the pressing switch two 55 and the pressing switch three 56, the weight of the sundries on the surface of the support plate 41 is judged, and the chemical dosing flow rate is controlled according to the weight of the sundries.

[0055] The traditional fixed chemical dosing flow rate method may cause waste or shortage of chemicals due to fluctuations in the sewage quality. Dynamically adjusting the chemical dosing flow rate according to the weight of the sundries can avoid unnecessary excessive dosing of chemicals, reduce the usage amount of chemicals, thereby reducing the chemical procurement cost. While ensuring the treatment effect, it realizes the rational utilization of resources and cost control. A reasonable chemical dosing flow rate helps to maintain the normal operation of the sewage treatment equipment. If the chemical dosing amount is too large, it may cause some equipment components to be chemically corroded or scaled, affecting the service life and performance of the equipment. By accurately adjusting the chemical dosing flow rate according to the weight of the sundries, the adverse effects of the chemicals on the equipment can be reduced, the maintenance cost and replacement frequency of the equipment can be lowered, and the overall service life of the equipment can be extended. Adjusting the chemical dosing flow rate in real time according to the weight of the sundries can enable the system to maintain a relatively stable treatment effect in the face of different water quality changes, and avoid the imbalance of the treatment system caused by water quality fluctuations.

[0056] Precise chemical dosing can ensure that the pollutants in the sewage are effectively treated, make the effluent water quality more in line with the environmental protection discharge standards, reduce the excessive use of chemicals, and also help to reduce the potential impact of chemical substances on the environment during the sewage treatment process, reflecting the concept of green environmental protection, which is conducive to enterprises or sewage treatment plants to meet the increasingly strict environmental protection supervision requirements. The weight of the sundries reflects to a certain extent the content of pollutants in the sewage. By real-time monitoring the weight of the sundries to adjust the chemical dosing flow rate, the chemical dosing amount can be matched with the content of pollutants in the sewage, realizing precise chemical dosing, avoiding the problem of poor treatment effect caused by too much or too little chemical dosing, ensuring that the chemical agents can fully play their roles in the sewage treatment process, effectively removing harmful substances in the sewage, and improving the effluent water quality.

[0057] The control component 6 includes a turntable 61 fixed to the outer wall of the third rotating rod 32, and a second pressing block 62 is fixed to the outer wall of the turntable 61. A fixing ring 63 is arranged outside the turntable 61, and a trigger switch 64 is fixed to the inner wall of the fixing ring 63. The end face of the fixing ring 63 is fixed to the outer wall of the operation box 13. On both sides of the surface of the collection box 35, a fourth connecting plate 65 is fixed. An electromagnet 66 is fixed to the top of the fourth connecting plate 65. Above the electromagnet 66, a first metal sheet 68 is arranged, and the first metal sheet 68 is fixed to the surface of a fifth connecting plate 67. The end face of the fifth connecting plate 67 is fixed to the surface of the baffle 36. According to the triggered state of the trigger switch 64, the opening and closing of the energized circuits of the first sliding rheostat 48 and the first switch plate 53 are realized. Moreover, when the trigger switch 64 is pressed, the energized state of the electromagnet 66 is controlled to change, so that the electromagnet 66 is energized, thereby realizing the discharge operation of the sundries. When the pressing state of the trigger switch 64 is released, the electromagnet 66 is controlled to be de-energized, and the repulsive force between the electromagnet 66 and the first metal sheet 68 disappears. Under the action of gravity and under the action of a spring or other reset devices, it automatically resets. The baffle 36 moves downward, and the baffle 36 closes the sewage outlet 38 again, which is convenient for the support plate 41 to monitor the weight of the sundries again.

[0058] When the first rotating rod 21 works, the first rotating rod 21 drives the fourth rotating rod 33 to rotate through the second belt 34. The fourth rotating rod 33 drives the third rotating rod 32 to rotate, and the third rotating rod 32 drives the scraping claws 31 to rotate. The scraping claws 31 rotate to scrape the sundries on the inner wall of the grille frame 15. Under the action of gravity, the sundries fall into the interior of the collection box 35. The sundries accumulate on the surface of the support plate 41. The heavier the sundries are, the greater the descending distance of the support plate 41 is. The support plate 41 drives the first connecting plate 42 to move downward. The first connecting plate 42 moves downward to compress the spring 43, so that the spring 43 is in a compressed and energy-storing state. The first connecting plate 42 drives the connecting rod 44 and the guiding plate 45 to move downward synchronously. The guiding plate 45 drives the second connecting plate 46 and the first elastic piece 47 to move downward synchronously. When the first elastic piece 47 moves, the resistance of the circuit it accesses will change. The first elastic piece 47 slides downward on the surface of the first sliding rheostat 48. When the first elastic piece 47 moves downward, the first elastic piece 47 moves in the direction that makes the length of the resistance wire in the circuit shorter, and the resistance of the accessed circuit decreases. According to Ohm's law, when the voltage remains unchanged, when the resistance decreases, the current in the circuit will increase. When the current increases, the rotation speed of the first motor 19 increases, and the first motor 19 drives the rotation speeds of the rotating rod 17 and the stirring rod 18 to increase synchronously, thereby increasing the stirring speed;

[0059] Adjust the stirring speed according to the descending distance of the first elastic piece 47, which can make the stirring intensity match the amount of impurities and the requirements of the chemical reaction. When the chemical dosing flow rate changes, adjust the stirring speed accordingly to ensure that the chemicals are evenly dispersed in the sewage. For example, when the chemical dosing flow rate increases, increasing the stirring speed can make the chemicals spread quickly, avoiding too high or too low local chemical concentration, ensuring that the chemicals fully contact and react with the pollutants in the sewage, improving the sewage treatment effect. The full mixing and reaction of the chemicals and sewage can more effectively remove pollutants, improve the effluent quality, ensure the stable operation of the sewage treatment system, reduce water quality fluctuations. Reasonable chemical dosing and stirring control accelerate the processes of coagulation, precipitation or decomposition of pollutants, making the sewage treatment process more efficient, enabling more sewage to be treated in the same time or shortening the treatment time when treating the same amount of sewage. When there are more impurities and chemicals, increase the stirring speed to strengthen the mixing reaction; otherwise, reduce the stirring speed to avoid over-stirring. Over-stirring will cause strong turbulence in the water body, increase the internal friction of the water flow, and lead to energy loss of the water flow;

[0060] At the same time, when the second connecting plate 46 moves downward, the movement of the second connecting plate 46 drives the third connecting plate 51 and the first pressing block 52 to move downward synchronously. The first pressing block 52 moves downward on the surface of the first switch plate 53. When there are fewer impurities on the surface of the support plate 41, the first pressing block 52 presses the first pressing switch 54. When there are medium impurities on the surface of the support plate 41, the first pressing block 52 presses the second pressing switch 55. When there are more impurities on the surface of the support plate 41, the first pressing block 52 presses the third pressing switch 56. Judge the weight of the impurities according to the triggering states of the first pressing switch 54, the second pressing switch 55 and the third pressing switch 56;

[0061] When the third rotating rod 32 rotates one circle, the third rotating rod 32 drives the turntable 61 and the second pressing block 62 to rotate synchronously. The second pressing block 62 presses and triggers the switch 64 once when it rotates one circle. When the trigger switch 64 is pressed, it is judged that the third rotating rod 32 rotates one circle. Moreover, when the trigger switch 64 is pressed and triggered, the circuits of the first sliding rheostat 48 and the first switch plate 53 are connected. At the same time, the first electromagnet 66 is controlled to be energized. After the first electromagnet 66 is energized, the first electromagnet 66 will generate a magnetic field after being energized. The magnetic pole of the first electromagnet 66 close to the first metal piece 68 is the same as the magnetic pole of the first metal piece 68 after being magnetized and close to the first electromagnet 66. According to the law of interaction between magnetic poles, like magnetic poles repel each other, so a repulsive force is generated between the first electromagnet 66 and the first metal piece 68. Under the action of the repulsive force, the first metal piece 68 is pushed upward. The first metal piece 68 drives the fifth connecting plate 67 and the baffle 36 to move upward synchronously. After the baffle 36 moves upward, the shielding of the sewage outlet 38 by the baffle 36 is released. Under the action of the inclined design on the surface of the support plate 41, the impurities enter the guiding shell 37 through the sewage outlet 38 and are discharged through the guiding shell 37. The impurities discharged from the guiding shell 37 are centrally collected by the collecting box 35.

[0062] The adjusting assembly 7 includes a medicine inlet seat 71 fixed to the inner wall of the medicine adding cylinder 12. A medicine inlet cavity 73 is formed inside the medicine inlet seat 71. An adjusting disc 72 is arranged inside the medicine inlet cavity 73. A limiting rod 74 is inserted into the adjusting disc 72, and the lower part of the limiting rod 74 is fixed to the surface of the medicine inlet seat 71. A second fixing plate 78 is fixed to the top of the adjusting disc 72, and the second fixing plate 78 is inserted into the protection cylinder 75. A support frame 79 is fixed to the outer wall of the protection cylinder 75, and the end face of the support frame 79 is fixed to the inner wall of the medicine adding cylinder 12. A first fixing plate 76 is fixed to the inner wall of the protection cylinder 75, and a second metal sheet 77 is fixed to the surface of the first fixing plate 76. An electromagnet two 781, an electromagnet three 782 and an electromagnet four 783 are sequentially arranged on the surface of the second fixing plate 78. The lower half section of the second fixing plate 78 is made of rubber material, and the outer wall of the second fixing plate 78 is tightly pressed against the bottom of the protection cylinder 75. When the adjusting disc 72 moves vertically, the limiting rod 74 is inserted into the adjusting disc 72 to limit the vertical movement of the adjusting disc 72, making the vertical movement of the adjusting disc 72 more stable.

[0063] By controlling the energization states of the electromagnet two 781, the electromagnet three 782 and the electromagnet four 783 corresponding to the triggered states of the pressing switch one 54, the pressing switch two 55 and the pressing switch three 56, the adjustment of the medicine adding flow rate is realized. The change of the debris weight can be accurately sensed according to the descending distance of the support plate 41, and the corresponding pressing switch one 54, pressing switch two 55 and pressing switch three 56 are automatically triggered, and the energization conditions of the electromagnet two 781, the electromagnet three 782 and the electromagnet four 783 are precisely controlled, so as to accurately adjust the medicine adding flow rate without manual intervention, improving the accuracy and automation degree of medicine adding. When the circuit is powered on, once the descending distance of the support plate 41 changes, the switch will immediately respond, and the electromagnet will also act quickly to realize the real-time adjustment of the medicine adding flow rate, and can quickly adapt to the dynamic change of the debris content in the sewage, ensuring the stability of the sewage treatment effect. This control method is based on simple mechanical triggering and electromagnetic control principles, with a relatively simple structure, not easily affected by the external environment, and the electromagnet acts quickly and accurately, and the on-off control of the switch is also relatively reliable, reducing the failure probability caused by a complex control system and improving the stability and reliability of the entire medicine adding system.

[0064] Open the top cover above the medicine adding cylinder 12, put in the medicine. The medicine is stored inside the medicine adding cylinder 12. The medicine adding flow rate is controlled by adjusting the distance between the adjusting disc 72 and the medicine inlet cavity 73. When the first pressing switch 54 is triggered, the second electromagnet 781 is controlled to be energized. After the second electromagnet 781 is energized, it generates magnetism. The second electromagnet 781 and the second metal sheet 77 have opposite magnetic poles. The second electromagnet 781 adsorbs the second metal sheet 77. Under the action of magnetism, the second electromagnet 781 and the second metal sheet 77 adsorb each other, and the distance between the adjusting disc 72 and the medicine inlet cavity 73 is in the minimum state. When the second pressing switch 55 is triggered, the third electromagnet 782 is controlled to be energized. Under the action of magnetism, the third electromagnet 782 and the second metal sheet 77 adsorb each other. The third electromagnet 782 drives the second fixing plate 78 to move upward, and the distance between the adjusting disc 72 and the medicine inlet cavity 73 is in the medium state. When the third pressing switch 56 is triggered, the fourth electromagnet 783 is controlled to be energized, and under the action of magnetism, the fourth electromagnet 783 and the second metal sheet 77 adsorb each other. The fourth electromagnet 783 drives the second fixing plate 78 to move upward, and the distance between the adjusting disc 72 and the medicine inlet cavity 73 is in the maximum state. By changing the energized states of the second electromagnet 781, the third electromagnet 782 and the fourth electromagnet 783, the vertical movement of the second fixing plate 78 and the adjusting disc 72 is driven, so as to realize the adjustment of the distance between the adjusting disc 72 and the medicine inlet cavity 73 and the adjustment operation of the medicine adding flow rate.

[0065] Embodiment 2

[0066] Please refer to Figures 11 to 13 , the second monitoring component 8 includes a sedimentation tank 81 opened inside the processing tank 11, and a filter screen 82 is fixed inside the sedimentation tank 81. A sedimentation cavity 83 is arranged below the filter screen 82. A buoy member 84 is arranged inside the sedimentation tank 81. A connecting rod 85 is fixed to the top of the buoy member 84. A connecting rope is arranged at the bottom of the buoy member 84, and the connecting rope is connected to the sedimentation cavity 83. A U-shaped pipe 86 is arranged at the bottom of the sedimentation cavity 83, and the U-shaped pipe 86 is connected to a vacuum pump 87. Utilizing the siphon phenomenon, a negative pressure is formed inside the U-shaped pipe 86 by pumping vacuum, so as to suck out the sediment mixture at the bottom of the sedimentation cavity 83. The U-shaped pipe 86 is used to guide the muddy water mixture to flow from the sedimentation cavity 83 to the mud discharge port. The mud suction port is located at one end of the U-shaped pipe 86 and is arranged at the bottom of the sedimentation cavity 83, which collects impurities such as sand and sludge deposited at the bottom of the tank. The mud discharge port is located at the other end of the U-shaped pipe 86 and is used to discharge the sucked sediment mixture to a designated sludge treatment system or other treatment equipment. The position of the mud discharge port is usually lower than the mud suction port to ensure that the muddy water mixture can be smoothly discharged under the action of gravity;

[0067] The vacuum pump 87 is used to create a vacuum inside the U-shaped tube 86 and initiate the siphon process. The vacuum pump 87 forms a vacuum by pumping out the air inside the U-shaped tube 86, reducing the pressure inside the tube. When the trigger switch 64 is triggered, first, the vacuum pump 87 is started to pump out the air inside the U-shaped tube 86, creating a certain degree of vacuum inside the tube. As a result, the pressure inside the tube is lower than the atmospheric pressure on the liquid surface in the sedimentation chamber 83 of the sewage treatment equipment. Under the action of the atmospheric pressure, the sediment mixture in the sedimentation chamber 83 is pressed into the mud suction port and enters the U-shaped tube 86. When the sediment mixture fills the U-shaped tube 86, since the outlet (mud discharge port) of the U-shaped tube 86 is lower than the liquid level in the tank, under the action of gravity, the mud-water mixture will continuously discharge from the mud discharge port, forming a continuous siphon phenomenon, realizing the cleaning of impurities such as sediment and gravel deposited at the bottom of the sedimentation chamber 83. When the trigger state of the trigger switch 64 is released, the mud discharge ends, the vacuum pump 87 is turned off, and air enters the U-shaped tube 86, destroying the siphon condition, and the mud discharge process stops.

[0068] The sewage filtered by the grille frame 15 enters the interior of the sedimentation tank 81. Under the action of the filter screen 82, most of the sediment is filtered by the filter screen 82 and enters the interior of the sedimentation chamber 83, accumulating inside the sedimentation chamber 83. The density of the sediment is greater than that of the sewage. Therefore, the sediment accumulates inside the sedimentation chamber 83. The density of the buoy member 84 is greater than that of the sewage, and the density of the buoy member 84 is less than that of the sediment. Therefore, the buoy member 84 floats on the surface of the sediment. By monitoring the height position of the buoy member 84, the accumulation situation of the sediment inside the sedimentation chamber 83 is judged. When the trigger switch 64 is triggered, the vacuum pump 87 is controlled to work. Under the action of the U-shaped tube 86, the sediment accumulated inside the sedimentation chamber 83 is pumped out to realize the sediment cleaning operation. After the pressing of the trigger switch 64 ends, the vacuum pump 87 stops working and the sediment extraction is cancelled.

[0069] The control component two 9 includes a second elastic piece 91 fixed to the end face of the connecting rod 85, and the second elastic piece 91 is slidably connected to the surface of the second sliding rheostat 92. A third pressing block 93 is fixed to the outer wall of the connecting rod 85, and the third pressing block 93 presses against the surface of the second switch board 94. The surface of the second switch board 94 is sequentially distributed with a fourth pressing switch 95, a fifth pressing switch 96, and a sixth pressing switch 97. The vertical movement of the buoy member 84 drives the connecting rod 85 to move synchronously. The movement of the connecting rod 85 drives the second elastic piece 91 and the third pressing block 93 to move. The second elastic piece 91 slides on the surface of the second sliding rheostat 92, and the third pressing block 93 moves on the surface of the second switch board 94. When the second elastic piece 91 moves upward on the surface of the second sliding rheostat 92, the resistance in the circuit decreases and the current increases, then the rotation speed of the first motor 19 is increased. On the contrary, when the second elastic piece 91 moves downward on the surface of the second sliding rheostat 92, the resistance in the circuit increases and the current decreases, reducing the rotation speed of the first motor 19;

[0070] When the pressure switch four 95 is triggered, it is determined that the sediment is in the thickest state, and the electromagnet four 783 is controlled to be energized. When the pressure switch five 96 is triggered, it is determined that the sediment is in the medium state, and the electromagnet three 782 is controlled to be energized. When the pressure switch six 97 is triggered, it is determined that the sediment is in the least state, and the electromagnet two 781 is controlled to be energized.

[0071] The rheostat one 48, switch board one 53, rheostat two 92 and switch board two 94 are in a parallel circuit. Branch one includes the rheostat one 48 and switch board one 53, which are connected in series on this branch; Branch two includes the rheostat two 92 and switch board two 94, which are connected in series on this branch. When the resistance of one of the branches is smaller, the current will pass through this branch. Therefore, when the grille frame 15 filters out more plants, the resistance of the rheostat one 48 decreases, resulting in a smaller resistance of this branch, and the current preferentially passes through this branch. The rheostat one 48 and switch board one 53 are energized. The chemical dosing flow rate of the adjustment component 7 is related to the triggering state of the switch board one 53, and the stirring speed of the stirring rod 18 is related to the elastic piece one 47 and rheostat one 48. When the filter screen 82 filters out more sediment, the resistance of this branch is smaller, the current passes through this circuit, and the rheostat two 92 and switch board two 94 are energized. The chemical dosing flow rate of the adjustment component 7 is related to the triggering state of the switch board two 94, and the stirring speed of the stirring rod 18 is related to the elastic piece two 91 and rheostat two 92, making the chemical dosing flow rate of the adjustment component 7 related to the heavier side. According to the change of the resistance values of the rheostat one 48 and rheostat two 92, the weights of the plants and sediment are judged, and the heavier side is taken as the control basis for the chemical dosing flow rate.

[0072] It can accurately adjust the chemical dosing amount according to the actual weight of pollutants. Whether it is plants or sediment, when the amount of one of the pollutants increases, the dosing system will correspondingly increase the dosing amount. It determines the dosing flow rate only based on the heavier side of the weight value, without the need to consider the complex combination of multiple pollutants at the same time. It can quickly respond to the change of the dominant pollutant in the sewage. When the weight of a certain pollutant increases significantly, the dosing system can immediately adjust the dosing flow rate according to this change, timely respond to the sudden change of water quality, avoid the deterioration of water quality caused by untimely treatment, ensure that the ratio of the medicament to the pollutant always remains within a suitable range, thereby improving the sewage treatment effect and ensuring stable compliance of the effluent water quality. It can simultaneously adapt to the treatment of sewage containing different proportions of plants and sediment. In the actual sewage treatment scenario, the types and contents of pollutants in the sewage will change continuously. This method can flexibly respond to various situations and is not affected by the change of a single pollutant, with stronger adaptability.
