Description

Technical Field

[0001] This application relates to the technical field of sewage treatment, and more particularly, to a sewage treatment device with a monitoring function. Background Art

[0002] Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains a large amount of pollutants and has a complex composition. It is not only difficult to purify in water but also difficult to treat. The pollutants contained in industrial wastewater vary greatly depending on the type of factory. Even for the same type of factory, the quality and quantity of pollutants contained are different due to different production processes. In addition to the wastewater discharged directly into the water body causing pollution, solid waste and waste gas can also pollute the water body. Agricultural pollution is mainly due to the loosening of the land surface during cultivation or reclamation. When it rains before the soil and terrain are stable, a large amount of sediment flows into the water, increasing the suspended solids in the water.

[0003] Existing sewage treatment devices usually directly transport sewage to the sewage tank, perform sedimentation treatment in the sewage tank, and then enter the centralized sedimentation in the sewage tank, resulting in too long sedimentation time. It is impossible to perform split-flow sedimentation on the sewage entering the sewage tank, thus greatly increasing the sedimentation time. At the same time, since the sewage takes a long time in the process of sedimentation separation, the sewage treatment rate is affected. At the same time, generally, an external device is used to provide an oxygenation effect for the sewage, thus greatly increasing the energy consumption. Therefore, the present invention provides a sewage treatment device with a monitoring function. Summary of the Invention

[0004] The main purpose of this application is to provide a sewage treatment device with a monitoring function, which realizes the piecemeal treatment of sewage by splitting the sewage, and then oxygenates the sewage during the flowing process and automatically cleans the sedimented sludge.

[0005] To achieve the above object, this application provides a sewage treatment device with a monitoring function, including a sedimentation cylinder and a sludge discharge mechanism assembled on the top of the sedimentation cylinder. Among them, the bottom of the sludge discharge mechanism is connected to the sedimentation cylinder through evenly spaced oxygenation mechanisms, and an aeration assembly for aerating the inside of the sludge discharge mechanism and the sedimentation cylinder is assembled on the top of the sludge discharge mechanism. The sludge discharge mechanism includes: An annular pipe, which is connected to the top of the evenly spaced oxygenation mechanisms, and the cross-section of the annular pipe is in a C-shaped structure. A sewage inlet pipe is connected to the side of the annular pipe. The top of the annular pipe is evenly provided with air inlets with an inclined cross-section along the circumferential direction, and the bottom of the annular pipe is evenly connected with guide sewage pipes communicating with the top of the oxygenation mechanisms along its circumferential direction; The rotating ring is rotatably connected to the inner side of the annular pipe, and blades extending into the interior of the annular pipe are fixedly arranged at equal intervals along the circumferential direction on the outer side of the rotating ring. A cross-shaped connecting rod is fixedly connected to the inner side of the rotating ring, and an auger is vertically fixed at the central position of the cross-shaped connecting rod. The sedimentation cylinder comprises: An outer cylinder, which is located at the outermost side of the sedimentation cylinder, and a drain pipe is connected to the bottom of the side of the outer cylinder, and a monitor is installed on the drain pipe. An inner cylinder, which is fixed inside the outer cylinder, and a mud guiding cylinder matching the auger is arranged at the middle position of the inner cylinder. Baffles are distributed at equal intervals between the mud guiding cylinder and the inner cylinder, and sedimentation tanks are formed between two adjacent baffles. Drainage tank openings communicating with the inside of the outer cylinder are formed at the tops of the sedimentation tanks. A connection opening communicating with the sedimentation tanks is formed at the bottom of the mud guiding cylinder, and the sedimentation tanks are communicated with the bottom end of the aeration mechanism.

[0006] Preferably, the inner bottom end of the sedimentation tank is in the shape of a conical flared opening with the middle lower and the outer side higher.

[0007] Preferably, a mud blocking ring is fixed at the top of the outer cylinder, and a mud discharging port is formed on the side surface of the mud blocking ring.

[0008] Preferably, a fixed sleeve is fixed at the top of the outer cylinder inside the mud blocking ring, and mud guiding openings are formed at equal intervals along the circumferential direction on the side surface of the fixed sleeve. A conical seat is arranged inside the fixed sleeve, and a through hole for the auger to pass through is formed at the central position of the conical seat.

[0009] Preferably, connecting pipes I communicating with the bottom end of the aeration mechanism are connected to the outer side of the fixed sleeve at equal intervals along the circumferential direction, and the connecting pipes I are communicated with the sedimentation tanks through connecting pipes II inside the fixed sleeve.

[0010] Preferably, the aeration assembly comprises an air inlet annular pipe fixed at the top of the sludge discharging mechanism, the bottom of the air inlet annular pipe is communicated with the air inlet through a pipeline, an air diffusing pipe for communicating the air inlet annular pipe and the sedimentation tanks is connected to the outer side of the air inlet annular pipe, and an air inlet pipe is connected to the top of the air inlet annular pipe.

[0011] Preferably, the aeration mechanism comprises a liquid guiding pipe I connected to the sewage guiding pipe and a liquid guiding pipe II connected to the connecting pipe I. A connecting ring is rotatably connected between the liquid guiding pipe I and the liquid guiding pipe II. A water wheel is fixedly connected to the inner side of the connecting ring. Fan blades are distributed at equal intervals on the outer side of the connecting ring. A conical cover is arranged on the outer side of the fan blades, and the bottom end of the conical cover is connected to the inside of the liquid guiding pipe II through an exhaust pipe.

[0012] The advantages of this application are as follows: First, the sewage enters the inside of the annular pipe from the sewage inlet pipe, causing the sewage to flow inside the annular pipe. During this process, the blades are driven to move along the inside of the annular pipe, thereby synchronously driving the rotating ring and the cross-shaped connecting rod to rotate, causing the auger to rotate. The sewage entering the inside of the annular pipe enters the inside of each aeration mechanism through the equally spaced sewage guiding pipes, and the sewage is introduced into the inside of each sedimentation tank through connecting pipe 1 and connecting pipe 2, diverting the sewage, thus facilitating the piecemeal treatment of the sewage and improving the sewage treatment effect; Second, when the sewage enters the inside of the aeration mechanism, it drives the water wheel and the connecting ring to rotate, synchronously rotating the fan blades, sucking the outside air into the inside of the conical cover, and entering the inside of the liquid guiding pipe 2 from the exhaust pipe, thereby combining with the sewage, thus supplementing the oxygen content in the sewage with the outside air. When the outside air enters the sewage, it may be in the form of bubbles. During the process of the bubbles flowing with the sewage, the water wheel and the blades are used to break up and stir the bubbles, thereby increasing the oxygen content in the sewage; Finally, the external aeration source is connected to the intake pipe, thereby entering the inside of the intake annular pipe and entering the inside of the intake port through the pipeline, aerating the sewage flowing through the inside of the annular pipe, and breaking up and stirring the bubbles during the rotation of the blades, further increasing the oxygen content in the sewage. And because the cross-section of the intake port is inclined and in the same direction as the flow direction of the sewage inside the annular pipe, when the gas enters the annular pipe, it has a certain driving force in the same direction as the sewage flow direction, thus facilitating the effect of assisting the rotation of the blades. At the same time, the gas synchronously enters the inside of the aeration pipe, thereby aerating the sewage precipitated in each sedimentation tank, further increasing the oxygen content in the sewage. At the same time, due to the branch pipes connected to the aeration pipe at equal intervals along its length direction and the outlets of the branch pipes are arranged on the inner side of the sedimentation tank, the gas blown out through the branch pipes provides an inward driving force for the sewage in the sedimentation tank, facilitating the aggregation of floating impurities towards the center, thereby improving the sedimentation effect of the sludge.

[0028] See Figures 1 - 8As shown in the figure, this embodiment provides a sewage treatment device with a monitoring function, including a sedimentation cylinder 400 and a sludge discharge mechanism 100 assembled at the top of the sedimentation cylinder 400. Among them, the bottom of the sludge discharge mechanism 100 is connected to the sedimentation cylinder 400 through an oxygenation mechanism 300 distributed at equal intervals, and an aeration assembly 200 for aerating the inside of the sludge discharge mechanism 100 and the sedimentation cylinder 400 is assembled at the top of the sludge discharge mechanism 100. The sludge discharge mechanism 100 includes: An annular pipe 104, which is connected to the tops of the oxygenation mechanisms 300 distributed at equal intervals. The cross-section of the annular pipe 104 is in a C-shaped structure, and a sewage inlet pipe 101 is connected to the side of the annular pipe 104. The top of the annular pipe 104 is provided with air inlets 107 with inclined cross-sections at equal intervals along the circumferential direction, and sewage guide pipes 106 connected to the tops of the oxygenation mechanisms 300 are connected to the bottom of the annular pipe 104 at equal intervals along its circumferential direction; A rotating ring 103, which is rotatably connected to the inside of the annular pipe 104. Blades 108 extending into the inside of the annular pipe 104 are fixedly arranged at equal intervals along the circumferential direction on the outside of the rotating ring 103. A cross-shaped connecting rod 102 is fixedly connected to the inside of the rotating ring 103, and an auger 105 is vertically fixed at the central position of the cross-shaped connecting rod 102; The sedimentation cylinder 400 includes: An outer cylinder, which is located on the outermost side of the sedimentation cylinder 400. A drain pipe 401 is connected to the bottom of the side of the outer cylinder, and a monitor 500 is installed on the drain pipe 401. During use, the monitor 500 is used to measure the OUR of the treated water. At the same time, it should be noted that in the present invention, the monitor 500 can be an oxygen consumption respiration rate meter, and the respiration rate is calculated by measuring the change in the dissolved oxygen concentration using a DO meter; An inner cylinder 411, which is fixed inside the outer cylinder. A mud guide cylinder 413 matching the auger 105 is arranged at the middle position of the inner cylinder 411. Baffles 410 are distributed at equal intervals between the mud guide cylinder 413 and the inner cylinder 411, and sedimentation tanks 412 are formed between adjacent two baffles 410. Drainage tank openings 409 communicating with the inside of the outer cylinder are opened at the tops of the sedimentation tanks 412. A connection port 414 communicating with the sedimentation tanks 412 is opened at the bottom of the mud guide cylinder 413, and the sedimentation tanks 412 are communicated with the bottom ends of the oxygenation mechanisms 300; In this embodiment, sewage enters the interior of the annular pipe 104 from the sewage inlet pipe 101, causing the sewage to flow inside the annular pipe 104. During this process, the blades 108 are driven to move along the interior of the annular pipe 104, thereby synchronously driving the rotation of the rotating ring 103 and the cross-shaped connecting rod 102, causing the auger 105 to rotate. The sewage that enters the interior of the annular pipe 104 enters the interior of each aeration mechanism 300 through the equally spaced sewage guiding pipes 106, and the sewage is introduced into the interior of each sedimentation tank 412 through the connecting pipe 1 403 and the connecting pipe 2 407, for the diversion of the sewage, thus facilitating the piecemeal treatment of the sewage and improving the sewage treatment effect. At the same time, the sedimented sludge enters the interior of the sludge guiding cylinder 413 from the position of the connection port 414, and during the rotation of the auger 105, the sludge is lifted upward along the interior of the sludge guiding cylinder 413 by the flow force of the sewage, thereby discharging the sludge from the interior of the sedimentation tank 412, facilitating the self-discharge of the sludge by the sewage during its flow. Subsequently, the sludge is discharged into the interior of the mud retaining ring 402 from the mud guiding port 405 under the action of the conical seat 408 and discharged from the mud discharge port 406. The sedimented water enters the interior of the outer cylinder from the position of the drainage trough opening 409 and is discharged from the drain pipe 401. During the discharge process, the discharged water is monitored by the monitor 500, and the OUR of the treated water is measured by the monitor 500.

[0029] As Figure 3 shown, in this embodiment, the inner bottom end of the sedimentation tank 412 is in the shape of a conical trumpet with a lower middle and a higher outer side. During use, the conical trumpet-shaped structure at the bottom of the sedimentation tank 412 is used to facilitate the aggregation of the sedimented sludge towards the position of the connection port 414.

[0030] As Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, in this embodiment, a mud retaining ring 402 is fixed to the top of the outer cylinder, and a mud discharge port 406 is provided on the side of the mud retaining ring 402. During use, after the sludge enters the interior of the mud retaining ring 402, it is discharged from the mud discharge port 406.

[0031] As Figure 3 shown, in this embodiment, a fixed sleeve 404 is fixed to the top of the outer cylinder inside the mud retaining ring 402, and mud guiding ports 405 are equally spaced along the circumferential direction on the side of the fixed sleeve 404. A conical seat 408 is provided inside the fixed sleeve 404, and a through hole for the auger 105 to pass through is provided at the central position of the conical seat 408. During use, the sludge is discharged into the interior of the mud retaining ring 402 from the mud guiding port 405 under the action of the conical seat 408.

[0032] As Figure 3As shown, in this embodiment, a first connecting pipe 403 communicating with the bottom end of the aeration mechanism 300 is connected to the outer side of the fixed sleeve 404 at equal intervals along its circumferential direction, and the first connecting pipe 403 is communicated with the sedimentation tank 412 through a second connecting pipe 407 inside the fixed sleeve 404. During use, sewage enters the interior of each aeration mechanism 300 through the equally spaced sewage guiding pipes 106, and then the sewage is introduced into the interior of each sedimentation tank 412 through the first connecting pipe 403 and the second connecting pipe 407.

[0033] As Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the aeration assembly 200 includes an air inlet annular pipe 201 fixed to the top of the sludge discharging mechanism 100. The bottom of the air inlet annular pipe 201 is communicated with the air inlet 107 through a pipeline, and an aeration pipe 203 for communicating the air inlet annular pipe 201 and the sedimentation tank 412 is connected to the outer side of the air inlet annular pipe 201. The top of the air inlet annular pipe 201 is connected with an air inlet pipe 202. During use, an external aeration source is connected to the air inlet pipe 202, so as to enter the interior of the air inlet annular pipe 201 and enter the interior of the air inlet 107 through the pipeline, aerating the sewage flowing through the interior of the annular pipe 104. Meanwhile, the gas synchronously enters the interior of the aeration pipe 203, so as to aerate the sewage sedimented in each sedimentation tank 412, further increasing the oxygen content in the sewage. At the same time, due to the branch pipes connected to the aeration pipe 203 at equal intervals along its length direction and the outlets of the branch pipes being arranged inside the sedimentation tank 412, the gas blown out by the branch pipes provides an inward driving force for the sewage in the sedimentation tank 412, facilitating the aggregation of floating impurities towards the center, thereby improving the sedimentation effect of the sludge.

[0034] As Figure 4As shown in the figure, in this embodiment, the oxygenation mechanism 300 includes a first liquid guide pipe 303 connected to the sewage guide pipe 106 and a second liquid guide pipe 306 connected to the first connecting pipe 403. A connecting ring 304 is rotatably connected between the first liquid guide pipe 303 and the second liquid guide pipe 306. A water wheel 302 is fixedly connected to the inner side of the connecting ring 304. A plurality of fan blades 305 are evenly distributed on the outer side of the connecting ring 304. A conical cover 301 is arranged on the outer side of the fan blades 305. The bottom end of the conical cover 301 is communicated with the inside of the second liquid guide pipe 306 through an exhaust pipe 307. During use, when sewage enters the oxygenation mechanism 300, the water wheel 302 and the connecting ring 304 are driven to rotate, and the fan blades 305 are rotated synchronously. The outside air is inhaled into the conical cover 301 and enters the inside of the second liquid guide pipe 306 through the exhaust pipe 307, so as to be combined with the sewage. Thus, the oxygen content in the sewage is supplemented by using the outside air. When the outside air enters the sewage, it may be in the form of bubbles. During the flow of the bubbles and the sewage, the water wheel 302 and the blade 108 are used to break up and stir the bubbles, so as to increase the oxygen content in the sewage.

[0035] To sum up: First, the sewage enters the inside of the annular pipe 104 from the sewage inlet pipe 101, so that the sewage flows inside the annular pipe 104. During this process, the blade 108 is driven to move along the inside of the annular pipe 104, so as to synchronously push the rotating ring 103 and the cross-shaped connecting rod 102 to rotate, and the auger 105 rotates. The sewage entering the annular pipe 104 enters the inside of each oxygenation mechanism 300 through the sewage guide pipes 106 evenly distributed, and the sewage is introduced into the inside of each sedimentation tank 412 through the first connecting pipe 403 and the second connecting pipe 407, so as to shunt the sewage, which is convenient for piecemeal treatment of the sewage and improves the sewage treatment effect. At the same time, the precipitated sludge enters the inside of the sludge guide cylinder 413 from the connection port 414. During the rotation of the auger 105, the sludge is lifted upward along the inside of the sludge guide cylinder 413 by the flowing force of the sewage, so as to discharge the sludge from the inside of the sedimentation tank 412, which is convenient for the sewage to automatically discharge the sludge during the flowing process. Subsequently, the sludge is discharged into the inside of the mud retaining ring 402 from the mud guide port 405 under the action of the conical seat 408 and discharged from the mud discharge port 406. The precipitated water enters the inside of the outer cylinder from the drainage tank opening 409 and is discharged from the drain pipe 401. During the discharge process, the discharged water is monitored by the monitor 500, and the OUR measurement of the treated water is carried out by using the monitor 500; When sewage enters the internal part of the aeration mechanism 300, it drives the water wheel 302 and the connecting ring 304 to rotate, and simultaneously rotates the fan blades 305, sucking external air into the inside of the conical cover 301 and entering the inside of the second liquid guide pipe 306 from the exhaust pipe 307, so as to combine with the sewage, and thus supplement the oxygen content in the sewage by using external air. When the external air enters the sewage, it may be in the form of bubbles. During the process of the bubbles flowing with the sewage, the water wheel 302 and the blades 108 are used to break up and stir the bubbles, thereby increasing the oxygen content in the sewage. During the sewage treatment process, it is connected to the intake pipe 202 through an external aeration source, and thus enters the inside of the intake annular pipe 201, and enters the inside of the intake port 107 through a pipeline to aerate the sewage flowing through the inside of the annular pipe 104. During the rotation of the blades 108, the bubbles are broken up and stirred, further increasing the oxygen content in the sewage. Since the cross-section of the intake port 107 is inclined and in the same direction as the flow direction of the sewage in the annular pipe 104, when the gas enters the annular pipe 104, it has a certain driving force in the same direction as the sewage flow direction, thus facilitating the effect of assisting the rotation of the blades 108. At the same time, the gas synchronously enters the inside of the aeration pipe 203, thereby aerating the sewage precipitated in each sedimentation tank 412, further increasing the oxygen content in the sewage. At the same time, due to the branch pipes connected to the aeration pipe 203 at equal intervals along its length direction and the outlets of the branch pipes are arranged inside the sedimentation tank 412, the gas blown out by the branch pipes provides an inward driving force for the sewage in the sedimentation tank 412, facilitating the aggregation of floating impurities towards the center, thereby improving the sedimentation effect of the sludge.
