Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a flocculation clarification wastewater treatment system for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life. Wastewater treatment systems require flocculation and clarification, thus necessitating the use of flocculation and clarification equipment. However, the following problems still exist in wastewater flocculation and sedimentation treatment:

[0003] The aeration effect is poor during the flocculation process of sewage, and the sewage cannot be fully aerated, which reduces the treatment effect of sewage aeration. Suspended solids will appear on the surface of the sewage during sewage aeration, and the inability to treat the suspended solids on the surface of the sewage in time will lead to low efficiency in the sewage treatment process. When the sewage is settled, the flocculents cannot be settled quickly, which takes a long time and is inconvenient to treat the sediment in time, thus wasting sewage treatment time.

The sedimentation filter plate is fixedly installed inside the installation groove, and the water baffle is fixedly installed at the connection between the second outlet pipe and the sedimentation tank.

[0022] A process for a flocculation clarification wastewater treatment system for wastewater treatment specifically includes the following steps:

[0023] Step 1: First, the sewage is discharged into the flocculation tank through the first inlet pipe. When the sewage reaches a certain height, the first motor and air generator start working. The first motor drives the T-tube to rotate through the transmission rod. The limiting roller meshes with the reciprocating spiral groove, so that the T-tube can move up and down while rotating. At the same time, the gas generated by the air generator enters the rotating sleeve through the air inlet pipe, then enters the T-tube through the air inlet hole, and then is discharged through the aeration hole of the aeration pipe to stir and aerate the sewage.

[0024] Step 2: During the aeration process, some sludge will float to the surface of the wastewater. The floating sludge enters the first floating box through the connection between the first floating box and the flocculation box. The floating sludge floats on the surface of the first floating box. At this time, the second motor drives the second rotating roller to rotate, which in turn drives the rotating belt to rotate. Then, the filter plate is used to transport the floating sludge to the top of the net box. At the same time, the second liquid pump uses the first circulation pipe to draw the wastewater from the bottom of the net box in the second floating box, and then sprays it out through the spray pipe to flush the filter plate, so that the floating sludge transported on the filter plate falls into the net box for unified collection.

[0025] Step 3: The aerated wastewater is then pumped through the first liquid pump at one end of the first outlet pipe and discharged into the sedimentation tank through the second inlet pipe. During sedimentation, sediment is generated in the sedimentation tank. At this point, the third liquid pump operates, using the second circulation pipe to pump out the mixture of sediment and wastewater. This mixture is then discharged into the conveying pipe through the third circulation pipe and circulation port. A return filter plate is used to separate the sediment from the wastewater. The sediment remains in the conveying pipe, and the third motor drives the conveying screw to rotate, causing the top of the sedimentation tank conveying pipe to move, finally discharging it from the discharge port.

[0026] Step 4: While the sediment is being circulated and discharged, the shaft of the conveying screw will drive the drive gear to rotate. Then, the drive gear meshes with the driven gear, which will drive the stirring rod to rotate, stirring the sewage and precipitating agent inside the sedimentation tank, so that the sewage and precipitating agent are better mixed.

[0027] Step 5; Finally, the wastewater after sedimentation is filtered again through the sedimentation filter plate installed on the baffle tank, and then discharged through the second outlet pipe.

[0028] The present invention has at least the following beneficial effects:

[0029] (1) This scheme sets up an aeration component. Specifically, the first motor and the air generator work. The first motor drives the T-tube to rotate through the transmission rod. The limit roller meshes with the reciprocating spiral groove, so that the T-tube can move up and down while rotating. At the same time, the gas generated by the air generator enters the rotating sleeve through the air inlet pipe, then enters the T-tube through the air inlet hole, and then is discharged through the aeration hole of the aeration pipe to agitate and aerate the sewage. Agitation at the same time as aeration effectively promotes the contact between oxygen and microorganisms in the water, improves the oxygen transfer rate and the biochemical reaction rate of the wastewater. At the same time, agitation can also prevent sludge, sediment and other substances from depositing and accumulating in the sewage, maintain the uniform distribution of suspended solids in the sewage, and improve the sewage treatment effect.

[0030] (2) This solution sets up a floating object treatment component. Specifically, the floating object enters the first floating box through the connection between the first floating box and the flocculation box. The floating object floats on the surface of the first floating box. At this time, the second motor drives the second rotating roller to rotate, thereby driving the rotating belt to rotate. Then, the filter plate is used to transport the floating dirt to the top of the net box. At the same time, the second liquid pump uses the first circulation pipe to draw the sewage from the bottom of the net box in the second floating box, and then sprays it out through the spray pipe to flush the filter plate, so that the floating dirt transported on the filter plate falls into the net box for unified collection, which facilitates the treatment of the floating dirt.

[0031] (3) This scheme sets up a sedimentation treatment component. During the sedimentation process, sediment is generated in the sedimentation tank. At this time, the third liquid pump works and uses the second circulation pipe to draw out the mixture of sediment and sewage. Then, it is discharged into the conveying pipe through the third circulation pipe and circulation port. At this time, the return filter plate is used to filter and separate the sediment and sewage. The sediment remains in the conveying pipe. The third motor drives the conveying screw to rotate, so that the top of the sedimentation tank conveying pipe moves and is finally discharged from the sewage outlet, which facilitates the rapid separation of sediment from the treated sewage.

[0032] (4) This solution sets up a sedimentation stirring component. Specifically, while the sediment is being circulated and discharged, the shaft of the conveying screw will drive the drive gear to rotate. Then the drive gear meshes with the driven gear, which will drive the stirring rod to rotate, stirring the sewage and sedimentation agent inside the sedimentation tank, so that the sewage and sedimentation agent are better mixed and the sewage treatment efficiency is improved.

[0033] (5) This solution sets up a sedimentation and filtration component. Specifically, the wastewater after sedimentation is filtered again by the sedimentation filter plate installed on the water baffle and then discharged through the second outlet pipe. This can completely separate the wastewater and sediment, prevent the discharged water from being mixed with sediment, and improve the wastewater treatment effect. Attached Figure Description

Then, it is discharged into the conveying pipe 504 through the circulation port 507 opened at one end of the third circulation pipe 503. At this time, it can be filtered by the return filter plate 508 installed at one end of the conveying pipe 504 to separate the sediment and sewage. The sediment remains in the conveying pipe 504.

[0059] In some embodiments, see Figure 9The sedimentation and filtration assembly includes an installation groove 702, which is located on one side of the water baffle 701. The sedimentation filter plate 703 is fixedly installed inside the installation groove 702. The water baffle 701 is fixedly installed at the connection between the second outlet pipe 202 and the sedimentation tank 2. After sedimentation, the wastewater is filtered again through the sedimentation filter plate 703 installed on the water baffle 701 and then discharged through the second outlet pipe 202, which can completely separate the wastewater and sediment.

[0060] The working process and principle of this invention are as follows: In use, wastewater is first discharged into the flocculation tank 1 through the first inlet pipe 101. When the wastewater reaches a certain height, the first motor 306 and the air generator 308 operate. The first motor 306 drives the T-tube 303 to rotate via the transmission rod 307. The limiting roller 305 engages with the reciprocating spiral groove 304, allowing the T-tube 303 to move up and down while rotating. Simultaneously, the gas generated by the air generator 308 enters the rotating sleeve 302 through the air inlet pipe 309, then enters the T-tube 303 through the air inlet hole 310, and finally passes through the aeration holes 31 of the aeration pipe 311. 2. The wastewater is discharged and aerated. During aeration, impurities will float to the surface. These floating impurities enter the first float box 401 through the connection between the first float box 401 and the flocculation box 1. The floating impurities float on the surface of the first float box 401. At this time, the second motor 407 drives the second roller 404 to rotate, thereby driving the rotating belt 405 to rotate. Then, the filter baffle 406 transports the floating impurities to the top of the mesh box 411. Simultaneously, the second liquid pump 409 uses the first circulation pipe 408 to draw wastewater from the bottom of the mesh box 411 in the second float box 402, and then sprays it out through the spray pipe 410 to flush the filter baffle 406, causing the filter baffle 406 to become flushed. Floating debris transported on the 6th conveyor falls into the net cage 411 for unified collection. The aerated wastewater is then pumped through the first liquid pump 103 at one end of the first outlet pipe 102 and discharged into the sedimentation tank 2 via the second inlet pipe 201 for chemical sedimentation. During sedimentation, sediment is generated in the sedimentation tank 2. At this time, the third liquid pump 502 operates, using the second circulation pipe 501 to pump out the mixture of sediment and wastewater. This mixture is then discharged into the conveying pipe 504 through the third circulation pipe 503 and circulation port 507. Here, the return filter plate 508 filters the sediment and wastewater, separating the sediment. The sediment remains in the conveying pipe. Inside pipe 504, the third motor 505 drives the conveying screw 506 to rotate, causing the top of the sedimentation tank conveying pipe 504 to move and finally discharge from the sewage outlet 509. At the same time, while the sediment is being circulated and discharged, the shaft of the conveying screw 506 will drive the drive gear 601 to rotate. Then, the drive gear 601 meshes with the driven gear 604, which will drive the stirring rod 603 to rotate, stirring the sewage and sedimentation agent inside the sedimentation tank 2, so that the sewage and sedimentation agent are better mixed. Finally, the sewage after sedimentation is filtered again through the sedimentation filter plate 703 installed on the baffle tank 701, and then discharged from the second outlet pipe 202.

5. The process of the flocculation clarification wastewater treatment system for wastewater treatment according to claim 4, characterized in that, Includes the following steps: Step 1: Wastewater is discharged into the flocculation box (1) through the first inlet pipe (101). When the wastewater reaches a certain height, the first motor (306) and the air generator (308) start working. The first motor (306) drives the T-tube (303) to rotate through the transmission rod (307). The limiting roller (305) meshes with the reciprocating spiral groove (304), so that the T-tube (303) can move up and down while rotating. At the same time, the gas generated by the air generator (308) enters the rotating sleeve (302) through the air inlet pipe (309), and then enters the T-tube (303) through the air inlet hole (310). Then it is discharged through the aeration hole (312) of the aeration pipe (311) to stir and aerate the wastewater. Step 2: During the aeration process, some sludge floats out of the sewage. The floating sludge enters the first floating box (401) through the connection between the first floating box (401) and the flocculation box (1). The floating sludge floats on the surface of the first floating box (401). At this time, the second motor (407) drives the second rotating roller (404) to rotate, thereby driving the rotating belt (405) to rotate. Then, the filter plate (406) is used to transport the floating sludge to the top of the net box (411). At the same time, the second liquid pump (409) uses the first circulation pipe (408) to draw sewage from the bottom of the net box (411) in the second floating box (402), and then sprays it out through the spray pipe (410) to flush the filter plate (406), so that the floating sludge transported on the filter plate (406) falls into the net box (411) for unified collection. Step 3: After aeration, the wastewater is pumped through the first liquid pump (103) at one end of the first outlet pipe (102) and discharged into the sedimentation tank (2) through the second inlet pipe (201) for sedimentation with added chemicals. During the sedimentation process, sediment is generated in the sedimentation tank (2). At this time, the third liquid pump (502) works and pumps out the mixture of sediment and wastewater through the second circulation pipe (501). Then, it is discharged into the conveying pipe (504) through the third circulation pipe (503) and circulation port (507). At this time, the return filter plate (508) is used for filtration to separate the sediment and wastewater. The sediment remains in the conveying pipe (504). The third motor (505) drives the conveying screw (506) to rotate, so that the sediment moves to the top of the conveying pipe (504) and is finally discharged from the sewage outlet (509). Step 4: While the sediment is being circulated and discharged, the shaft of the conveying screw (506) drives the drive gear (601) to rotate. Then the drive gear (601) meshes with the driven gear (604), driving the stirring rod (603) to rotate, stirring the sewage and precipitating agent inside the sedimentation tank (2), so that the sewage and precipitating agent are better mixed. Step 5: After sedimentation, the wastewater is filtered again through the sedimentation filter plate (703) installed on the water baffle (701), and then discharged through the second outlet pipe (202).
