Description

Technical Field

[0001] This invention relates to the field of urban wastewater treatment, specifically to an automated purification device and method for urban wastewater. Background Technology

[0002] Urban sewage refers to domestic wastewater, industrial wastewater, and runoff sewage within urban areas. It is generally collected by urban pipe networks and treated at urban sewage treatment plants before being discharged into water bodies. In addition to containing large amounts of organic matter, bacteria, and viruses, urban sewage is increasingly complex in quality due to rapid industrial development, and runoff sewage pollution is becoming increasingly severe. Urban sewage treatment refers to measures taken to change the nature of sewage and prevent it from harming the environment and water bodies. Urban sewage treatment is generally divided into three levels: primary treatment, which uses physical methods to remove insoluble pollutants and parasite eggs; secondary treatment, which uses biological methods to oxidize and degrade various complex organic substances in sewage into simpler substances; and tertiary treatment, which uses chemical precipitation, biochemical methods, and physicochemical methods to remove phosphorus, nitrogen, and recalcitrant organic matter from sewage.

[0003] Existing patent document CN218841904U discloses a multi-stage treatment device for urban sewage sludge. By installing sedimentation and filtration chambers, the urban sewage to be treated flows into the sedimentation chamber, where a stirring shaft, temperature sensor, heating element, and sludge collection hopper effectively settle and remove sludge. The filtration chamber, equipped with activated carbon filter plates in the first and second filter cylinders, performs multi-stage filtration and purification. Finally, a sterilization chamber with an ozone generator and air duct assembly effectively sterilizes the wastewater. This device integrates sedimentation, multi-stage filtration, and sterilization, improving sewage treatment efficiency. However, while this application document features multi-stage filtration, the large amount of accumulated filter material cannot be promptly removed after filtration, easily clogging the filter plates and affecting the continuous filtration of subsequent sewage. Therefore, there is an urgent need for an automated purification device and method for urban sewage. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing wastewater purification equipment where large amounts of accumulated filter media cannot be promptly removed after filtration, leading to easy clogging of the filter plates and affecting the continuous filtration of subsequent wastewater; existing aeration pipes fixed inside the aeration tank, resulting in varying aeration effects due to changes in wastewater height, which in turn affects the activity of microorganisms in the wastewater; and the difficulty in completely cleaning sludge deposited inside the purification tank.

[0015] Preferably, the purification method of the automated purification equipment for urban sewage includes the following steps:

[0016] Step 1: Discharge urban sewage into the purification tank through sewage pipes, where it undergoes initial filtration through the filtration structure;

[0017] Step 2: After filtration, the wastewater enters the purification tank for initial sedimentation;

[0018] Step 3: After filtration, oxygen is evenly introduced into the wastewater through the aeration structure, mixes with the wastewater, and accelerates the microbial reaction;

[0019] Step 4: After the reaction, the microorganisms and wastewater undergo secondary sedimentation;

[0020] Step 5: Discharge the wastewater and sludge separately after sedimentation and stratification.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] First, this invention, by setting up a filter box, a collection box, a pusher plate, and a filter plate, allows wastewater to fall into the filter box through a wastewater pipe, while the filtered impurities remain on the filter plate. When impurities accumulate, the first motor in the equipment box is controlled to drive the rotating rod at the output end and the pusher plate to rotate. As the pusher plate rotates, it continuously pushes the impurities through the conveyor plate and onto the collection box, preventing impurities from remaining on the filter plate and causing blockage. Furthermore, when too many impurities accumulate in the collection box, a pressure sensor detects the pressure caused by the accumulation of impurities, thereby triggering an alarm system controlled by the PLC controller to issue an alarm, allowing staff to promptly detect and handle the impurities.

[0023] Secondly, this invention, by setting up a first aeration pipe, a second aeration pipe, a first air outlet trough, a second air outlet trough, and an air pump, allows the falling wastewater to undergo initial sedimentation in the purification tank. After a period of sedimentation, most impurities settle on the feeding plate. At this time, two second motors are controlled to operate, driving the output screw to rotate. When the screw rotates inside the limit box, it drives the threaded sleeve and the first and second aeration pipes to move downwards through the thread. Simultaneously, the first and second aeration pipes move on the sliding rod through sliding frames on both sides, which can improve the stability of the downward movement. After the first and second aeration pipes move downwards, they enter the wastewater... In the water, depending on the amount of sewage, if there is a lot of sewage, both air pumps on the left side of the first aeration pipe are turned on. The oxygen in the air inlet pipe is divided into two parts through two hoses and enters the first aeration pipe through the connecting pipe, and then enters the first air outlet and the second air outlet respectively. Finally, it is sprayed out through the air outlets at the top and bottom. At this time, the first aeration pipe and the second aeration pipe are in the middle of the sewage, and the oxygen is sprayed evenly in both the top and bottom directions, so that the oxygen and sewage mix more quickly, the microbial reaction is more rapid, and thus the sewage purification efficiency is improved.

[0024] Third, this invention, by setting up a feeding plate, a hemispherical block, a hydraulic push rod, and a vibration motor, allows purified water to flow out through a drain pipe after secondary sedimentation. After flowing out, the hydraulic push rod is controlled to extend the hemispherical block at the output end. The hemispherical block moves upward and pushes the left end of the feeding plate to rotate upward through the rotating seat, thus raising it and causing the left side to tilt to the right. At the same time, the power supply in the vibration groove inside the feeding plate provides power to multiple vibration motors, so that the vibration motors generate vibration force after being powered on, and the vibration is transmitted to the feeding plate. Under the action of tilting and vibration, the microbial sludge on the feeding plate slides to the right and flows out through the sewage pipe. After it has completely flowed out, the purification of urban sewage is completed. Attached Figure Description

The machine 304 has a rotating rod 305 at its output end. A pusher plate 306 is installed on the outer wall of the rotating rod 305. A collection box 308 is located on the left side of the conveyor plate 307. A pressure sensor 309 is installed on the inner wall of the collection box 308. An air inlet pipe 11 is connected to the right side of the purification tank 1, and a sewage discharge pipe 15 is connected to the left side of the purification tank 1. A return pipe 13 is installed on one side of the sewage discharge pipe 15. A drain pipe 17 is connected to the right side of the purification tank 1. A first sludge pump 14 is installed on the return pipe 13, and a second sludge pump 16 is installed on the sewage discharge pipe 15. There are two sets of limit boxes 4. A lead screw 5 and a sliding rod 9 are respectively installed on the inner side of each set of limit boxes 4. A sliding frame 8 is sleeved on the outer wall of the sliding rod 9. The limit boxes 4 are welded to the inner wall of the purification tank 1, and the sliding rod... 9 is fixedly connected to the limit box 4.

The filter box 301 and the purification tank 1 are fixedly installed via the equipment box 302 and the mounting plate 303. The first motor 304 is fixedly installed to the equipment box 302 via a mounting groove. The right end of the rotating rod 305 is rotatably connected to the inner wall of the filter box 301 via a rotating shaft. The bottom of the collection box 308 is provided with a water permeable hole. The pressure sensor 309 is equipped with an alarm function. The bottom end of the filter box 301 is provided with a filter plate 310. The filter box 301 and the collection box 308 are fixed to the top of the purification tank 1 via the equipment box 302 and the mounting plate 303. After fixing, the filter box 301 is located below the sewage pipe 2. At this time, the sewage falls into the filter box 301 through the sewage pipe 2. After being filtered by the bottom filter plate 310, the wastewater falls into the purification tank 1, while the filtered impurities remain on the filter plate 310. When impurities accumulate, the first motor 304 in the control box 302 is activated. The internal technology of the first motor 304 is existing technology. After the first motor 304 is activated, it drives the rotating rod 305 at the output end and the pusher plate 306 to rotate. When the pusher plate 306 rotates, it continuously pushes the impurities through the conveyor plate 307 and slides them into the collection box 308, so that the impurities do not remain on the filter plate 310 and cause blockage. When too many impurities accumulate in the collection box 308, the pressure sensor 309 senses the pressure caused by the accumulation of impurities, and thus controls the alarm system through the PLC controller to issue an alarm, so that the staff can discover the problem in time.This allows for the timely removal of impurities.

[0042] Please see Figure 7-10An automated purification device and method for urban sewage is disclosed. The aeration structure 10 includes a first aeration pipe 1001, with a first air outlet groove 1002 inside the first aeration pipe 1001. Air outlets 1004 are provided at both the upper and lower ends of the first aeration pipe 1001. A connecting pipe 1006 is connected to the left side of the first aeration pipe 1001. A second air outlet groove 1003 is provided below the first air outlet groove 1002. An air pump 1005 is installed on the connecting pipe 1006, and a flexible hose 1007 is connected to the left side of the connecting pipe 1006. There are two sets of limiting boxes 4. A lead screw 5 and a sliding rod 9 are respectively provided on the inner side of the two sets of limiting boxes 4. A sliding frame 8 is sleeved on the outer wall of the sliding rod 9. The limiting boxes 4 are welded to the inner wall of the purification tank 1, and the sliding rod 9 and the... The limiting box 4 is fixedly connected, and the bottom end of the lead screw 5 is rotatably connected to the limiting box 4 through a bearing. The top end of the lead screw 5 is equipped with a second motor 6. A threaded sleeve 7 is movably sleeved on the outer wall of the lead screw 5. The first aeration pipe 1001, the second aeration pipe 1008, the lead screw 5, and the slide rod 9 are fixedly connected to each other through the threaded sleeve 7 and the sliding frame 8, respectively. The threaded sleeve 7 is movably connected to the lead screw 5 through a thread. There are three sets of air pump 1005, connecting pipe 1006, and hose 1007. The hose 1007 is fixedly connected to the air inlet pipe 11. Each set of connecting pipe 1006 passes through the inner side of the first air outlet groove 1002 and the second air outlet groove 1003, respectively. The air outlet head 1004 passes through the inner side of the first air outlet groove 1002 and the second air outlet groove 1003, respectively. The first aeration pipe 1001, the second aeration pipe 1008, the first aeration pipe 1009, the second aeration pipe 10 ... The first aeration pipe 1001 and the second aeration pipe 1008 are connected to each other at both ends of the purification tank 1. The first aeration pipe 1001 and the second aeration pipe 1008 are both provided with a first air outlet groove 1002 and a second air outlet groove 1003. The sewage falling into the purification tank 1 undergoes initial sedimentation. After sedimentation for a period of time, most of the impurities are deposited on the feeding plate 1201. At this time, the two second motors 6 are controlled to run. The internal technology of the second motors 6 is existing technology. After the second motors 6 run, they drive the output end screw 5 to rotate. When the screw 5 rotates inside the limit box 4, it drives the threaded sleeve 7 and the first aeration pipe 1001 and the second aeration pipe 1008 to move downward through the thread. At the same time, the first aeration pipe 1001 and the second aeration pipe 1008 move on the slide rod 9 through the sliding frame 8 on both sides, which can improve the downward movement. To ensure stability, after the first aeration pipe 1001 and the second aeration pipe 1008 move downwards, they enter the sewage. Depending on the amount of sewage, if there is a large amount of sewage, both air pumps 1005 on the left side of the first aeration pipe 1001 are turned on. Oxygen in the air inlet pipe 11 is then divided into two parts through two hoses 1007 and enters the first aeration pipe 1001 through the connecting pipe 1006, and then enters the first air outlet 1002 and the second air outlet 1003 respectively. Finally, it is ejected through the air outlets 1004 at both ends. At this time, the first aeration pipe 1001 and the second aeration pipe 1008 are in the middle of the sewage, and oxygen is evenly ejected from both the upper and lower directions, allowing the oxygen to mix with the sewage more quickly.Microorganisms react more rapidly, thus improving the efficiency of wastewater purification.

[0043] Please see Figure 11-14 An automated purification device and method for urban sewage is disclosed. The feeding structure 12 includes a feeding plate 1201, a hemispherical block 1202 attached to the bottom of the feeding plate 1201, and a vibration groove 1204 formed inside the feeding plate 1201. A sealing plate 1208 is provided on the side of the feeding plate 1201. A hydraulic push rod 1203 is installed at the bottom of the hemispherical block 1202. A sealing plate 1205 is engaged at the bottom of the vibration groove 1204, and a power supply unit 1206 is installed on the inner wall of the vibration groove 1204. A vibration motor 1207 is installed at the top of assembly 1206. The right end of the feeding plate 1201 is movably connected to the purification tank 1 via a rotating seat. An arc-shaped groove is provided at the bottom end of the feeding plate 1201. The hydraulic push rod 1203 is fixedly installed to the purification tank 1 via an installation groove. The hemispherical block 1202 is fixedly connected to the output end of the hydraulic push rod 1203. The sealing plate 1205 is fixedly engaged with the vibration groove 1204 via a locking buckle, and a sealing ring is provided on the side of the vibration groove 1204. The vibration motor 1207 and the power supply assembly 1206 are connected via a power cord. Electrical connection, after aeration, microorganisms and wastewater undergo secondary sedimentation, forming purified water and microbial sludge sediment. Simultaneously, some microbial sludge enters the wastewater pipe 2 through the return pipe 13, where it mixes with new wastewater for further filtration and purification. After secondary sedimentation, the purified water flows out through the drain pipe 17. After flowing out, the hydraulic push rod 1203 is activated. The internal technology of the hydraulic push rod 1203 is existing technology. After the hydraulic push rod 1203 operates, it drives the hemispherical block 1202 at the output end to extend. The upward movement of the hemispherical block 1202 pushes the conveyor belt... The left end of the feeding plate 1201 is raised by rotating upwards via a rotating seat, forming a tilt from left to right. At the same time, the power supply group 1206 in the vibration groove 1204 inside the feeding plate 1201 provides power to multiple vibration motors 1207. After the vibration motors 1207 are powered on, they generate vibration force, which is transmitted to the feeding plate 1201. Under the action of tilting and vibration, the microbial sludge on the feeding plate 1201 slides to the right and flows out through the sewage pipe 15. After it has completely flowed out, the urban sewage purification is completed.

[0044] A purification method for an automated wastewater purification device for urban sewage includes the following steps:

[0045] Step 1: The urban sewage is discharged into the purification tank 1 through the sewage pipe 2, and first passes through the primary filtration structure 3;

[0046] Step 2: After filtration, the wastewater enters purification tank 1 for initial sedimentation;

[0047] Step 3: After filtration, oxygen is evenly introduced into the wastewater through aeration structure 10, mixes with the wastewater, and accelerates the microbial reaction;

[0048] Step 4: After the reaction, the microorganisms and wastewater undergo secondary sedimentation;

[0049] Step 5: Discharge the wastewater and sludge separately after sedimentation and stratification.

[0050] Working Principle: In use, the filter box 301 and the collection box 308 are fixed to the top of the purification tank 1 via the equipment box 302 and the mounting plate 303. After fixing, the filter box 301 is positioned below the sewage pipe 2. At this time, sewage falls into the filter box 301 through the sewage pipe 2 and is filtered by the bottom filter plate 310 before falling into the purification tank 1. The filtered impurities remain on the filter plate 310. When impurities accumulate, the first motor 304 in the equipment box 302 is activated. The internal technology of the first motor 304 is existing technology. After the first motor 304 is activated, it drives the rotating rod 305 and the pusher plate 306 at the output end to rotate. When the pusher plate 306 rotates, it continuously pushes the impurities through the conveying plate 307 and onto the collection box. In box 308, impurities are prevented from accumulating on filter plate 310 and causing blockage. When excessive impurities accumulate in box 308, pressure sensor 309 senses the pressure caused by the accumulation and triggers an alarm system via PLC controller, allowing staff to promptly detect and address the impurities. The wastewater undergoes initial sedimentation in purification tank 1. After sedimentation for a period, most impurities settle on feeding plate 1201. At this point, two second motors 6 are activated. The internal technology of the second motors 6 is existing. When the second motors 6 are activated, they drive the output screw 5 to rotate. As the screw 5 rotates inside the limit box 4, it drives the threaded sleeve 7, the first aeration pipe 1001, and the second aeration pipe 1008 to move downwards via the thread. Simultaneously, the first aeration... The first aeration pipe 1001 and the second aeration pipe 1008 move on the slide rod 9 via sliding frames 8 on both sides, which can improve the stability of the downward movement. After the first aeration pipe 1001 and the second aeration pipe 1008 move downward, they enter the sewage. Depending on the amount of sewage, if there is a lot of sewage, both air pumps 1005 on the left side of the first aeration pipe 1001 are turned on. Then the oxygen in the air inlet pipe 11 is divided into two parts through two hoses 1007 and enters the first aeration pipe 1001 through the connecting pipe 1006. It then enters the first air outlet 1002 and the second air outlet 1003 respectively, and is finally sprayed out through the air outlets 1004 at the upper and lower ends. At this time, the first aeration pipe 1001 and the second aeration pipe 1008 are in the middle of the sewage, and the first aeration pipe 1001... 01. The second aeration pipe 1008 sprays oxygen evenly in both vertical and horizontal directions, allowing the oxygen to mix with the sewage more quickly and the microbial reaction to be more rapid, thereby improving the sewage purification efficiency. After the aeration reaction, the microorganisms and sewage undergo secondary sedimentation, forming purified water and microbial sludge sediment. At the same time, some microbial sludge enters the sewage pipe 2 through the return pipe 13, where it is filtered and purified again with the new sewage. After the secondary sedimentation is completed, the purified water flows out through the drain pipe 17. After flowing out, the hydraulic push rod 1203 is controlled to operate. The internal technology of the hydraulic push rod 1203 is existing technology. After the hydraulic push rod 1203 operates, it drives the hemispherical block 1202 at the output end to extend. After the hemispherical block 1202 moves upward, it pushes the left end of the feeding plate 1201 to rotate upward through the rotating seat and lift it.The feed plate 1201 tilts from left to right, and the power supply unit 1206 in the internal vibration groove 1204 provides power to multiple vibration motors 1207. When the vibration motors 1207 are powered on, they generate vibration force, which is transmitted to the feed plate 1201. Under the influence of the tilt and vibration, the microbial sludge on the feed plate 1201 slides to the right and flows out through the drain pipe 15. After it has completely drained, the urban sewage purification is complete.
