[0016] Compared with the prior art, the present invention provides a wastewater treatment device and a multi-process combination method for treating glass grinding wastewater, which has the following beneficial effects: 1. In this type of wastewater treatment equipment, after dewatering, the increased internal weight of the dewatering filter screen causes the pollutant dewatering cylinder to move downwards. As the pollutant dewatering cylinder moves downwards, the supporting spring is compressed, and the cylinder separates from the compression limiting ring, releasing the clamping force on the dewatering filter screen. This allows the filter screen to move downwards and gradually extend from inside the pollutant dewatering cylinder. As the filter screen moves downwards, the portion containing the flocculants falls into the pollutant storage chamber. A partition baffle separates the filter screen. Then, the supporting spring rebounds, causing the pollutant dewatering cylinder to move upwards and clamp the filter screen through contact with the compression limiting ring. The filtered flocculants are promptly segmented and stored for unified treatment, effectively preventing pollutants from clogging the filter holes and reducing maintenance pressure.

[0017] 2. This type of wastewater treatment equipment has multiple inclined sedimentation pipes installed inside the wastewater sedimentation tank. Wastewater entering the sedimentation tank moves upward along the sedimentation pipes. Inside the sedimentation tank, flocs not only settle within the tank but also within the sedimentation pipes. The flocs settled within the sedimentation pipes slide down to the bottom of the sedimentation tank. As the wastewater volume in the sedimentation tank gradually increases, it can be discharged through a combined drain pipe and a wastewater outlet. The flocs settled at the bottom of the sedimentation tank can then be introduced into the dewatering mechanism by opening the sediment outlet. By increasing the sedimentation area of ​​the flocs within the sedimentation tank and guiding the wastewater upward through the sedimentation pipes, the flow velocity of the wastewater inside the sedimentation tank is reduced, thus improving sedimentation efficiency.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a wastewater treatment device and a multi-process combination method for treating glass grinding wastewater.

[0022] Example 1: Please see Figure 1 - Figure 12 A wastewater treatment device includes a housing 1, a wastewater electrocoagulation mechanism 2 installed inside the housing 1, a delivery pump 3 installed inside the housing 1, a delivery pipe 4 connected to the outside of the delivery pump 3, a sedimentation mechanism 5 installed inside the housing 1, and a dewatering mechanism 6 installed inside the housing 1. Both sides of the conveying pump 3 are equipped with conveying pipes 4. The wastewater electrocoagulation mechanism 2 and the sedimentation mechanism 5 are connected through the conveying pump 3 and the conveying pipes 4. The sedimentation mechanism 5 is installed above the dewatering mechanism 6, and the bottom of the sedimentation mechanism 5 is connected to the bottom of the dewatering mechanism 6. The wastewater electrocoagulation unit 2 is connected to an external water inlet. The wastewater electrocoagulation unit 2 can generate metal ions in the wastewater to form flocs from the pollutants in the wastewater. The delivery pump 3 can transport the wastewater and flocs in the wastewater electrocoagulation unit 2 to the interior of the sedimentation unit 5 through the delivery pipe 4. After the flocs in the sedimentation unit 5 settle, they enter the dewatering unit 6. The wastewater in the sedimentation unit 5 is discharged from the top of the sedimentation unit 5. The dewatering unit 6 can dewater the flocs inside.

[0023] During operation, wastewater is first injected into the wastewater electrocoagulation unit 2. The wastewater electrocoagulation unit 2 can generate flocs in the wastewater through electrolysis. The flocs adsorb pollutants and suspended solids in the wastewater. Then, the delivery pump 3 can transport the wastewater and flocs inside the wastewater electrocoagulation unit 2 to the sedimentation unit 5 through the delivery pipe 4. The flocs gradually settle inside the sedimentation unit 5. The settled flocs enter the dewatering unit 6 from the bottom of the sedimentation unit 5, while the wastewater is discharged from the top of the sedimentation unit 5. After the flocs enter the dewatering unit 6, the dewatering unit 6 can dehydrate the flocs by rotating. The dehydrated flocs can be stored in batches inside the dewatering unit 6 for periodic unified cleaning. During operation, the flocs formed by electrolysis absorb pollutants and suspended solids. In addition, the pollutants are stored in batches during the filtration process, which can effectively prevent pollutants from clogging the filter holes and reduce maintenance pressure.

[0024] Example 2: The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The wastewater electrocoagulation mechanism 2 includes a wastewater electrocoagulation chamber 21 and a conductor mounting frame 22. The wastewater electrocoagulation chamber 21 is fixedly installed at the bottom inside the equipment housing 1, and the conductor mounting frame 22 is fixedly installed at the top inside the equipment housing 1. A current-carrying conductor 23 is connected to the bottom of the conductor mounting frame 22. An exhaust pipe 24 is connected to the top of the wastewater electrocoagulation chamber 21. A wastewater inlet 25 is connected to the outside of the wastewater electrocoagulation chamber 21, and an electrocoagulation delivery port 26 is provided on the outside of the wastewater electrocoagulation chamber 21.

[0025] The interior of the wastewater electrocoagulation chamber 21 is connected to the external water inlet through the wastewater inlet 25, and the interior of the wastewater electrocoagulation chamber 21 is connected to the conveying pipe 4 through the electrocoagulation conveying port 26. Wastewater inlet 25 can guide wastewater into the interior of wastewater electrocoagulation chamber 21 by connecting to an external wastewater pipeline, and conveying pump 3 can convey wastewater from wastewater electrocoagulation chamber 21 to the interior of sedimentation mechanism 5 by connecting to electrocoagulation conveying port 26 through conveying pipe 4.

[0026] The bottom of the current-carrying conductor 23 passes through the top of the wastewater electrocoagulation chamber 21 and extends into the interior of the wastewater electrocoagulation chamber 21. The exhaust pipe 24 passes through the side wall of the equipment shell 1, and the interior of the wastewater electrocoagulation chamber 21 is connected to the exterior of the equipment shell 1 through the exhaust pipe 24. The wastewater electrocoagulation unit 2 can generate metal ions in wastewater to produce flocs. When generating metal ions, the wastewater electrocoagulation unit 2 also generates gas. The gas inside the wastewater electrocoagulation unit 2 is discharged to the outside of the equipment shell 1 through the exhaust pipe 24.

[0027] During operation, external wastewater can enter the interior of the wastewater electrocoagulation chamber 21 through the wastewater inlet 25. After the energized conductor 23 is energized, flocs will form in the wastewater of the wastewater electrocoagulation chamber 21 to absorb pollutants and suspended solids. During the energization process, gas will also be generated inside the wastewater electrocoagulation chamber 21. The gas generated inside the wastewater electrocoagulation chamber 21 can be discharged to the outside of the equipment shell 1 through the exhaust pipe 24. When flocs are generated inside the wastewater electrocoagulation chamber 21, the flocs can absorb suspended solids and pollutants in the wastewater. After the flocs inside the wastewater electrocoagulation chamber 21 are sufficient, the delivery pump 3 is started, and the wastewater and flocs inside the wastewater electrocoagulation chamber 21 are transported to the interior of the sedimentation mechanism 5 through the delivery pipe 4. The flocs generated by electrolysis absorb pollutants and suspended solids in the wastewater, which can avoid the need to add chemical agents to the wastewater multiple times.

[0028] Example 3: The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The sedimentation mechanism 5 includes a wastewater sedimentation tank 51, which is fixedly installed inside the equipment housing 1. A sedimentation tank inlet 52 is provided on one side of the wastewater sedimentation tank 51. Multiple sedimentation pipes 53 are installed inside the wastewater sedimentation tank 51. A merging connection pipe 54 is installed outside the wastewater sedimentation tank 51. A wastewater outlet 55 is provided outside the merging connection pipe 54. A sediment outlet 56 is connected to the bottom of the wastewater sedimentation tank 51. The interior of the wastewater sedimentation tank 51 is connected to the conveying pipe 4 through the sedimentation pipe 53. The bottom of the interior of the wastewater sedimentation tank 51 is an inclined structure towards the center. The conveying pump 3 can be connected to the sedimentation tank inlet 52 through the conveying pipe 4 to transport wastewater into the interior of the wastewater sedimentation tank 51.

[0029] Multiple sedimentation pipes 53 are inclined at a certain angle inside the wastewater sedimentation tank 51. One end of each sedimentation pipe 53 passes through the side wall of the wastewater sedimentation tank 51 and connects to the inside of the combined connection pipe 54. The combined connection pipe 54 is connected to the outside of the equipment shell 1 through the wastewater discharge outlet 55. Wastewater inside the wastewater sedimentation tank 51 can enter the confluence connection pipe 54 through the sedimentation pipe 53 and then flow out from the wastewater outlet 55. The sedimentation pipe 53 can increase the sedimentation area of ​​flocs inside the wastewater sedimentation tank 51. The flocs inside the wastewater sedimentation tank 51 can enter the dewatering mechanism 6 through the sediment outlet 56.

[0030] During operation, the delivery pump 3 transports wastewater from the sedimentation tank inlet 52 at the bottom of the wastewater sedimentation tank 51 to the interior of the wastewater sedimentation tank 51 through the delivery pipe 4. Multiple inclined sedimentation pipes 53 are installed inside the wastewater sedimentation tank 51. The wastewater entering the wastewater sedimentation tank 51 moves upward along the sedimentation pipes 53. Inside the wastewater sedimentation tank 51, flocs not only settle inside the wastewater sedimentation tank 51 but also inside the sedimentation pipes 53. The flocs settled inside the sedimentation pipes 53 can slide down to the bottom of the wastewater sedimentation tank 51. As the wastewater in the wastewater sedimentation tank 51 gradually increases, the wastewater can be discharged through the confluence connection pipe 54 and the wastewater outlet 55. Then, by opening the sediment outlet 56, the flocs settled at the bottom of the wastewater sedimentation tank 51 can enter the dewatering mechanism 6. By increasing the sedimentation area of ​​the flocs inside the wastewater sedimentation tank 51 and guiding the wastewater upward through the sedimentation pipes 53, the flow velocity of the wastewater inside the wastewater sedimentation tank 51 is reduced, thereby improving sedimentation efficiency.

[0031] Example 4: The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The dehydration mechanism 6 includes a rotating base 61, which is fixedly installed at the bottom inside the equipment housing 1. The top of the rotating base 61 is connected to the dehydration housing 62. A contaminant storage chamber 63 is rotatably installed inside the dehydration housing 62. A support spring 64 is installed inside the contaminant storage chamber 63. A contaminant dehydration cylinder 65 is connected to the top of the support spring 64. A dehydration filter screen 66 is installed inside the contaminant dehydration cylinder 65. A partition baffle 67 is installed inside the contaminant dehydration cylinder 65. A compression limiting ring 68 is rotatably installed inside the dehydration housing 62. A dehydration drain outlet 69 is connected to the outside of the dehydration housing 62.

[0032] The pollutant dehydration cylinder 65 is slidably installed between the compression limiting ring 68 and the pollutant storage chamber 63. The bottom of the pollutant dehydration cylinder 65 is connected to the inside of the pollutant storage chamber 63 through the support spring 64. The pollutant dehydration cylinder 65 can roll the dehydration filter 66 into the inside of the pollutant dehydration cylinder 65. The pollutant dehydration cylinder 65 and the compression limiting ring 68 can fix the position of the dehydration filter 66. The rotating base 61 can drive the pollutant storage chamber 63 to rotate inside the dehydration shell 62. When the pollutant storage chamber 63 rotates, it can drive the pollutant dehydration cylinder 65 to rotate synchronously. When the pollutant dehydration cylinder 65 rotates, it can drive the compression limit ring 68 to rotate synchronously. When the pollutant dehydration cylinder 65 rotates, it can drive the internal dehydration filter screen 66 to rotate synchronously.

[0033] Both the pollutant storage chamber 63 and the pollutant dehydration cylinder 65 have drainage holes on their side walls. The pollutant dehydration cylinder 65 is connected to the interior of the dehydration shell 62 through the drainage holes on its side wall. The bottom of the pollutant dehydration cylinder 65 is connected to the interior of the pollutant storage chamber 63 through a partition baffle 67. The pollutant storage chamber 63 is connected to the interior of the dehydration shell 62 through the drainage holes on its side wall. The interior of the dehydration shell 62 is connected to the exterior of the equipment shell 1 through a dehydration drain outlet 69. When the pollutant dewatering cylinder 65 rotates, it can drive the dewatering filter screen 66 to rotate and dewater the flocs. The sewage in the pollutant dewatering cylinder 65 and the pollutant storage chamber 63 can enter the interior of the dewatering shell 62 through the drain hole. The sewage inside the dewatering shell 62 can be discharged through the dewatering drain port 69. The dewatering filter screen 66 can pass through the partition baffle 67 and enter the interior of the pollutant storage chamber 63.

[0034] During operation, the rotating base 61 drives the pollutant storage chamber 63 to rotate inside the dehydration shell 62. The rotation of the pollutant storage chamber 63 causes the pollutant dehydration cylinder 65 to rotate synchronously. The rotation of the pollutant dehydration cylinder 65 causes the compression limiting ring 68 to rotate synchronously. The rotation of the pollutant dehydration cylinder 65 also causes the internal dehydration filter screen 66 to rotate synchronously. The flocculent material falls into the dehydration filter screen 66 through the sediment discharge port 56. The rotation of the dehydration filter screen 66 dehydrates the flocculent material. Wastewater from both the pollutant dehydration cylinder 65 and the pollutant storage chamber 63 enters the dehydration shell 62 through the drain hole. Wastewater inside the dehydration shell 62 is discharged through the dehydration drain port 69. After dehydration, the increased internal weight of the dehydration filter screen 66 causes the pollutant dehydration cylinder 65 to move downwards. When the dewatering cylinder 65 moves downward, it compresses the support spring 64. After the pollutant dewatering cylinder 65 moves downward, it separates from the compression limiting ring 68, loosening the clamping of the dewatering filter screen 66. This allows the dewatering filter screen 66 to move downward and gradually extend from the inside of the pollutant dewatering cylinder 65. As the dewatering filter screen 66 moves downward, the portion containing the flocculants falls into the pollutant storage chamber 63. The separating baffle 67 separates the dewatering filter screen 66. Then, the support spring 64 rebounds, causing the pollutant dewatering cylinder 65 to move upward. The pollutant dewatering cylinder 65 then contacts the compression limiting ring 68 and clamps the dewatering filter screen 66. The dewatering filter screen 66 promptly segments and stores the filtered flocculants for unified processing, effectively preventing pollutants from clogging the filter holes and reducing maintenance pressure.

The delivery pump 3 can transport the wastewater in the wastewater electrocoagulation unit 2 to the interior of the sedimentation unit 5 through the delivery pipe 4; After settling, the flocs inside the sedimentation unit 5 can enter the dewatering unit 6. The dehydration unit 6 can dehydrate the flocs before storing them in batches.
