Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sedimentation and water separation device equipped with an oxidation ditch. Background Technology

[0002] Wastewater treatment is the process of removing pollutants from wastewater through physical, chemical, and biological means to ensure that the water quality meets discharge standards or reuse requirements, ultimately achieving water resource recycling or safe discharge. It is a core component in protecting the water environment and alleviating water shortages, and is widely used in domestic, industrial, and agricultural sectors.

[0003] While current sedimentation and water separation devices can settle and separate wastewater, they still have some shortcomings in actual use. For example, during use, they facilitate the rapid discharge of large particles in wastewater, causing these large particles to settle along with smaller particles, leading to blockages and increased wear on the equipment.

[0004] Based on this, the present invention designs a sedimentation and water separation device with an oxidation ditch to solve the problem. Utility Model Content

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a sedimentation and water separation device with an oxidation ditch, including a frame 1, an oxidation ditch assembly 2 above the frame 1, the oxidation ditch assembly 2 including an annular shell 201 fixedly installed on the upper surface of the frame 1, a connecting pipe 203 fixedly connected to the right side of the annular shell 201, a control valve 204 fixedly connected to the right end of the connecting pipe 203, a conduit 205 fixedly connected to the right end of the control valve 204, a separation assembly 3 on the right side of the oxidation ditch assembly 2, the separation assembly 3 including a first cylinder 301, the right end of the conduit 205 fixedly connected to the left side of the first cylinder 301, a bracket 302 fixedly installed on the upper surface of the first cylinder 301, a conveying assembly 4 on the right side of the separation assembly 3, the input end of the conveying assembly 4 fixedly connected to the right side of the first cylinder 301, and the output end of the conveying assembly 4 connected to a sedimentation assembly 5, the sedimentation assembly 5 including a second cylinder 501, a filter plate 502 fixedly installed on the inner wall of the second cylinder 501.

[0019] Please see Figure 2Two support plates 206 are fixedly installed on the inner wall of the annular shell 201. Submersible propulsion aerators 207 are installed on the side of the two support plates 206 that are far apart from each other. The submersible propulsion aerators 207 can make the sewage flow inside the annular shell 201 and provide oxygen to the microorganisms in the sewage.

[0020] Please see Figure 3 A hydraulic cylinder 303 is fixedly installed on the upper surface of the bracket 302. A connecting frame 304 is fixedly installed on the telescopic end of the hydraulic cylinder 303. Two sets of through-holes 305 are opened on the upper surface of the connecting frame 304. A filter screen 306 is fixedly installed on the inner wall of each through-hole 305. The hydraulic cylinder 303 can control the connecting frame 304 and the filter screen 306 to move up and down, so that the filter screen 306 can drive the intercepted large particles to move upward, so that the staff can clean them.

[0021] Please see Figure 1 The conveying assembly 4 includes a first bend 401 installed on the right side of the first cylinder 301. The top end of the first bend 401 is fixedly connected to a sludge pump 402. The output end of the sludge pump 402 is fixedly connected to a second bend 403. The right end of the second bend 403 is fixedly connected to the left side of the second cylinder 501.

[0022] The back of the second cylinder 501 is fixedly connected to a connecting cylinder 504. A motor 505 is fixedly installed on the back of the connecting cylinder 504. A screw conveyor shaft 506 adapted to the connecting cylinder 504 is fixedly installed at the output end of the motor 505. A sludge outlet pipe 507 is fixedly connected to the outer surface of the connecting cylinder 504. With the cooperation of the motor 505 and the screw conveyor shaft 506, the sludge settled inside the second cylinder 501 can be transported, so that the sludge can enter the interior of the annular shell 201, ensuring the content of microorganisms inside the sludge.

[0023] Please see Figure 1 The left side of the annular shell 201 is fixedly connected to an inlet pipe 202, and the back side of the annular shell 201 is fixedly connected to a return pipe 208. Wastewater can be added through the inlet pipe 202, and the return pipe 208 can facilitate the entry of sludge into the interior of the annular shell 201.

[0024] Please see Figure 4 The right side of the second cylinder 501 is fixedly connected to a drain pipe 503, which is located above the filter plate 502. The drain pipe 503 is located above the filter plate 502, which can effectively prevent fine particles in the sewage from being discharged.

[0025] The implementation principle of a sedimentation and water separation device with an oxidation ditch according to this utility model embodiment is as follows: During use, wastewater is injected into the annular shell 201 through the inlet pipe 202. Then, the submersible aerator 207 is started, allowing the wastewater to flow inside the annular shell 201, preventing sludge coagulation and ensuring thorough mixing between the sludge and wastewater. This allows the microorganisms in the sludge to decompose the organic matter in the wastewater. After decomposition, the control valve 204 is opened, allowing the wastewater to enter the first cylinder 301 through the connecting pipe 203 and the conduit 205. The filter screen 306 intercepts large particles in the wastewater, allowing it to enter the bottom of the first cylinder 301. Then, the sludge pump 402 is started to further decompose the wastewater. Sewage and sludge inside cylinder 301 are extracted and discharged into the second cylinder 501, allowing the sewage to settle inside the second cylinder 501. As the sewage increases, the filter plate 502 intercepts the sludge, allowing water to be discharged through the drain pipe 503. The sludge outlet pipe 507 and the return pipe 208 are connected. Then, the motor 505 is started, which drives the screw conveyor shaft 506 to rotate, allowing the screw conveyor shaft 506 to collect the sludge and allow it to enter the annular shell 201. When there are many large particles above the filter screen 306, the hydraulic cylinder 303 is activated, which drives the connecting frame 304 to move upward, allowing the workers to clean up the large particles.
