[0002] The sedimentation device widely used in the field of water treatment mainly includes horizontal flow sedimentation tank, inclined tube (plate) sedimentation tank. Among them, the inclined plate type sedimentation tank is widely applied due to its small land occupation, high processing efficiency, simple operation and maintenance and other advantages. The existing inclined plate sedimentation device generally includes a sedimentation tank, and a plurality of parallel arranged inclined plates are arranged in the sedimentation tank. These inclined plates are usually arranged at a certain angle, so that when water flows, suspended particles are settled on the surface of the inclined plate under the action of gravity and slide along the inclined plate to the bottom of the sedimentation tank. This design can increase the settling area, thereby improving the solid-liquid separation efficiency.

A guide plate 208 is provided below the left partition 205 and the right partition 206. The left partition 205 and the guide plate 208 form a left water inlet channel 50, and the right partition 206 and the guide plate 208 form a right water inlet channel 60; a plurality of mutually parallel and spaced first inclined plates 209 are provided between the left side plate 201 and the left partition 205, and a plurality of mutually parallel and spaced second inclined plates 210 are provided between the right side plate 202 and the right partition 206. A plurality of mutually parallel and spaced outlet weirs 211 are provided above the first inclined plates 209 and the second inclined plates 210. The bottom of the first inclined plate 209 is located at the water inlet of the left water inlet channel 50, and the bottom of the second inclined plate 210 is located at the water inlet of the right water inlet channel 60.

[0037] The principle of the present application is that after supplying water to the aerobic tank 10, the water flow enters the channel formed between the left partition plate 205 and the right partition plate 206, and then is divided into two parts by the action of the water distribution plate 207, enters the bottom of the first inclined plate 209 through the left water inlet channel 50, and enters the bottom of the second inclined plate 210 through the right water inlet channel 60. In this way, the water flow enters from the bottom of the first inclined plate 209 and the second inclined plate 210, and rises through the channel between the two inclined plates, effectively reducing the risk of blockage, especially when treating wastewater with high suspended solids concentration, showing good stability.

[0038] The present application can uniformly distribute the fluid after entering the sedimentation mechanism through the middle water inlet method, avoiding the turbulent flow generated in the side or corner. The sedimentation rate and sedimentation efficiency of the sediment are improved, thereby improving the overall treatment capacity.

[0039] The present application integrates the sedimentation mechanism 20 with the aerobic tank 10, and directly integrates the sedimentation mechanism 20 into the inside of the aerobic tank 10. This design not only saves the construction space and cost of the independent sedimentation mechanism, but also simplifies the arrangement and installation of the system, improves the overall operation efficiency and economy.

[0040] Water is supplied from the bottom of the first inclined plate 209 and the second inclined plate 210, effectively reducing the risk of blockage between the inclined plates, and is particularly suitable for treating wastewater with high suspended solids concentration.

[0041] In specific implementation, the bottom side wall of the aerobic tank 10 is provided with a vent pipe 101, and the rear side of the aerobic tank 10 is provided with a water inlet pipe 102.

[0042] The water inlet connected with the water inlet pipe 102 is arranged at the middle position of the sedimentation mechanism, aligned with the center of the sedimentation mechanism 20. The shape of the water inlet can be circular or rectangular, and the specific shape should be selected according to the fluid flow characteristics and sedimentation requirements. The size and position of the water inlet are optimized to ensure that the fluid can be uniformly distributed in the sedimentation area.

[0043] A guide plate or guide pipe is arranged around the water inlet for adjusting the flow rate and flow direction of the fluid. The design of the guide plate or guide pipe aims to reduce turbulence and unevenness in the fluid flow and optimize the sedimentation process.

[0044] In specific implementation, the water inlet pipe 102 is connected with a total water inlet channel 212, and the total water inlet channel 212 delivers water to the channel formed between the left partition plate 205 and the right partition plate 206.

[0045] The present application adopts a middle water inlet mode to introduce water flow from the rear side of the aerobic tank 10 into the sedimentation mechanism 20. This water inlet mode can maintain the original water flow pattern in the aerobic tank 10, avoid flow pattern disturbance caused by the change of the water inlet mode, and thus ensure the treatment effect of the aerobic tank 10 and the operation stability of the sedimentation device.

[0046] In specific implementation, the first inclined plates 209 are parallel to each other, the distance between two adjacent first inclined plates 209 is 2-18 cm, the length of each first inclined plate 209 is at least 50 cm, and the angle of each first inclined plate 209 relative to the horizontal plane is 55-60 degrees.

[0048] In order to achieve the best sedimentation effect, the present application optimizes the setting angle and distance of the first inclined plate 209 and the second inclined plate 210. The first inclined plate 209 and the second inclined plate 210 are arranged at a specific angle, which not only ensures the effective sedimentation of suspended particles, but also prevents the blockage problem between the inclined plates, and improves the treatment capacity and operation stability of the device.

[0049] In specific implementation, the first inclined plates 209 and the second inclined plates 210 are fixedly connected together by a frame (not shown in the figure).

[0050] In the design, the present application considers the convenience of maintenance and cleaning of the device. Through the detachable and adjustable first inclined plate 209 and the second inclined plate 210, the user can conveniently clean and maintain the device, and reduce the problems caused by the attachment of sludge, bacteria and algae during operation.
