Description

Technical Field

[0001] This utility model belongs to the field of environmental pollution treatment, specifically relating to a biochemical treatment device for industrial wastewater from photovoltaic power generation. Background Technology

[0002] Photovoltaic power generation industrial wastewater refers to industrial wastewater generated in the photovoltaic power generation industry chain, especially in the manufacturing process of photovoltaic cells and modules. Due to different production processes and raw materials, this type of wastewater has complex composition, high pollutant concentration, and is difficult to treat.

[0003] In existing technologies, wastewater and precipitant are not mixed evenly, making it difficult for the precipitant to fully contact the pollutants in the wastewater, resulting in low sedimentation efficiency and some pollutants that cannot be effectively precipitated and removed. The filter structure of existing wastewater treatment devices is prone to clogging after long-term use, leading to a decrease in filtration effect. Moreover, cleaning the filter structure requires shutdown, affecting the continuity and efficiency of wastewater treatment.

[0004] In summary, existing wastewater treatment devices suffer from problems such as low sedimentation efficiency and easy clogging and cleaning of the filter structure due to insufficient mixing during the mixing process. Utility Model Content

[0005] To overcome the problems of low sedimentation efficiency and easy clogging and cleaning of filter structures caused by insufficient mixing in existing wastewater treatment devices, a biochemical treatment device for photovoltaic power generation industrial wastewater is proposed.

[0006] The technical solution of this utility model is as follows: a biochemical treatment device for industrial wastewater from photovoltaic power generation, including a treatment box; it also includes a fixed column and a stirring blade. A separation sleeve is fixedly connected to the upper end of the treatment box, and a fixed column is fixedly connected to the inner wall of the separation sleeve. A spiral groove in a spiral state is opened on the fixed column, and the spiral groove passes through the lower end of the fixed column. A first liquid injection groove is opened at the upper end of the fixed column, and multiple second liquid injection grooves are opened on the inner wall of the first liquid injection groove. The second liquid injection grooves and the spiral grooves are interconnected. A liquid injection connecting pipe is fixedly connected to the fixed column at the first liquid injection groove. A stirring blade is provided inside the separation sleeve. A uniformly distributed first filter groove is opened through the arc-shaped outer wall of the separation sleeve. A filter plate is provided inside the separation sleeve, and a second filter groove is opened through the filter plate. Four first drain pipes are fixedly connected through the lower end of the treatment box.

[0007] Preferably, a flow-guiding platform is fixed to the lower end of the inner wall of the treatment box located at the separation sleeve. The integrated structure formed by the treatment box and the flow-guiding platform has a uniformly distributed third liquid injection tank. A water injection ring is provided at the lower end of the treatment box located at the third liquid injection tank.

[0008] Preferably, a multi-stage pump is provided at the lower end of the treatment box, and two connecting pipes are fixedly connected to the input end of the multi-stage pump. The connecting pipes and the first drain pipe are interconnected.

[0009] Preferably, the treatment box and the drainage platform form an integrated structure with a drainage trough extending through the upper and lower ends. The lower part of the treatment box is connected to a second drainage pipe through the drainage trough, and a solenoid valve is installed on the second drainage pipe.

[0010] Preferably, a motor is fixedly connected to the lower end of the processing box, and the output shaft of the motor passes through the processing box and the flow guide platform and is fixedly connected to the lower end of the stirring blade.

[0011] Preferably, the end where the filter plate and the stirring blade are in contact with each other is sloped, and the lower part of the outer wall of the stirring blade and the inner wall of the filter plate are in contact with each other.

[0012] Preferably, the outer wall of the end of the flow-guiding platform away from the axis of the separation sleeve is inclined, and the angle between the inclined surfaces of the flow-guiding platform and the filter plate is 90 degrees.

[0013] The beneficial effects of this utility model are as follows: the spiral groove set on the fixed column increases the wastewater flow time; the second injection tank opened on the fixed column at the same time allows subsequent precipitant to be injected into the spiral groove, which is fully mixed during the wastewater flow, thereby improving the overall sedimentation efficiency; then, the split filtration method separates most of the residue and other larger particles in the wastewater from part of the liquid, thus facilitating the subsequent full treatment of wastewater.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5 This utility model provides an embodiment of a biochemical treatment device for photovoltaic power generation industrial wastewater, including a treatment box 1; it also includes a fixed column 3 and a stirring blade 12. A separation sleeve 2 is fixedly connected to the upper end of the treatment box 1, and the fixed column 3 is fixedly connected to the inner wall of the separation sleeve 2. The fixed column 3 has a spiral groove 21 in a spiral state, which extends through the lower end of the fixed column 3. A first injection groove 14 is opened at the upper end of the fixed column 3, and a plurality of second injection grooves 15 are opened on the inner wall of the first injection groove 14. The second injection grooves 15 and the spiral groove 21 are interconnected. An injection connecting pipe 4 is fixedly connected to the fixed column 3 through the first injection groove 14. The stirring blade 12 is arranged inside the separation sleeve 2. The arc-shaped outer wall is permeated with a uniformly distributed first filter groove 13. A filter plate 19 is installed inside the separation sleeve 2, and a second filter groove 20 is permeated on the filter plate 19. Four first drain pipes 5 are fixedly connected to the lower end of the treatment box 1. The spiral groove 21 set on the fixed column 3 increases the wastewater flow time. The second injection groove 15 opened on the fixed column 3 at the same time can inject the subsequent precipitant into the spiral groove 21. During the wastewater flow, it is fully mixed, thereby improving the overall sedimentation efficiency. Then, through the split filtration method, most of the residue and other larger particles in the wastewater are separated from part of the liquid, thus facilitating the subsequent full treatment of wastewater.

[0022] Please see Figures 1-3 In this embodiment, a multi-stage pump 6 is provided at the lower end of the processing box 1. Two connecting pipes 7 are fixedly connected to the input end of the multi-stage pump 6. The connecting pipes 7 and the first drain pipe 5 are connected to each other. The liquid is pumped into the water injection ring 8 and then sprayed out of the water injection ring 8 under high pressure, thereby cleaning the second filter tank 20 and the first filter tank 13. A motor 11 is fixedly connected to the lower end of the processing box 1. The output shaft of the motor 11 passes through the processing box 1 and the diversion table 17 and is fixedly connected to the lower end of the stirring blade 12. By turning on the motor 11, its output shaft drives the stirring blade 12 to rotate.

[0023] Please see Figures 3-5In this embodiment, a diversion platform 17 is fixedly connected to the lower end of the inner wall of the treatment box 1 located at the separation sleeve 2. The integrated structure formed by the treatment box 1 and the diversion platform 17 has a uniformly distributed third injection groove 18 extending through it. A water injection ring 8 is provided at the lower end of the treatment box 1 located at the third injection groove 18. The integrated structure formed by the treatment box 1 and the diversion platform 17 has a drain groove 16 extending through it at both the upper and lower ends. A second drain pipe 9 is fixedly connected to the lower part of the treatment box 1 at the drain groove 16. A solenoid valve 10 is provided on the second drain pipe 9. By opening the solenoid valve 10... The filter plate 19 can be used to discharge the sediment. The filter plate 19 and the stirring blade 12 are in a slope shape at the end where they are attached to each other. The lower part of the outer wall of the stirring blade 12 is in contact with the inner wall of the filter plate 19. The outer wall of the guide platform 17 away from the axis of the separation sleeve 2 is inclined, and the angle between the inclined surfaces of the guide platform 17 and the filter plate 19 is 90 degrees. The liquid on the filter plate 19 is discharged into the outer wall of the guide platform 17 through the second filter tank 20. Then, the liquid is filtered a second time through the first filter tank 13 on the separation sleeve 2.

[0024] During operation, industrial wastewater is discharged above the fixed column 3 and flows into the separation sleeve 2 through the spiral groove 21 on the fixed column 3. Simultaneously, precipitant is injected into the first injection tank 14 through the injection connecting pipe 4. Then, the precipitant flows through the first injection tank 14 and into the spiral groove 21 through the second injection tank 15 to mix with the wastewater. This ensures uniform mixing of the wastewater and precipitant during the flow through the spiral groove 21. The mixture then flows onto the filter plate 19. The motor 11 is activated to drive the stirring blades 12 to stir the filter plate 19, allowing the settled liquid to pass through the filter plate 19 sequentially. After the second filter tank 20 and the first filter tank 13 flow into the outside of the separation sleeve 2, the liquid is then processed through the first drain pipe 5. When the liquid flows into the first drain pipe 5, the multi-stage pump 6 is turned on, and part of the liquid is flushed and filtered through the second filter tank 20 on the water injection ring 8 to flush the second filter tank 20 on the filter plate 19 and the first filter tank 13 on the separation sleeve 2. After filtration is completed, the solenoid valve 10 on the second drain pipe 9 is turned on to let the sediment waste liquid at the top of the filter plate 19 flow out from the second drain pipe 9, thereby improving the efficiency of wastewater treatment.
