All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1-2, the present utility model provides a technical solution: a glass fiber wastewater advanced treatment device, including an advanced treatment device main body 1. Inside the advanced treatment device main body 1, there are a water inlet tank 3, a water inlet buffer tank 12, a secondary filtration tank 6, a biological reaction tank 7, and a water purification tank 8. There is a water inlet tank side wall 4 between the water inlet tank 3 and the water inlet buffer tank 12, and the bottom of the water inlet tank side wall 4 is a sedimentation inclined plate 404 with a symmetric structure. And a spiral dirt cleaner 11 is installed below between the sedimentation inclined plates 404. Above the water inlet tank 3, a chemical reagent addition tank 2 is installed. And inside the water inlet tank 3, there is a water inlet treatment cylinder 10. And a water inlet filter screen 1001 is provided at the lower part of the water inlet treatment cylinder 10. Inside the water inlet tank 3, there is also an annular limiting frame 402, and the annular limiting frame 402 is inserted and fixed with the water inlet pipe 301. And the water inlet treatment cylinder 10 longitudinally moves through the annular limiting frame 402. This structure can stably process the water inlet pipe 301 through the annular limiting frame 402 and perform detachable limiting treatment on the water inlet treatment cylinder 10 to ensure the connection between the water inlet pipe 301 and the water inlet treatment cylinder 10. So that the glass fiber wastewater can directly enter the water inlet treatment cylinder 10 through the water inlet pipe 301. A first communication hole 401 is opened on the side surface of the water inlet tank side wall 4, and the first communication hole 401 is above the position of the water inlet filter screen 1001. This structure can allow the filtered and sedimented wastewater in the water inlet tank 3 to enter the water inlet buffer tank 12 through the first communication hole 401. A stirrer 9 is installed inside the water inlet treatment cylinder 10. And a water inlet pipe 301 communicating with the water inlet treatment cylinder 10 is provided on the side surface of the water inlet tank 3. The upper ends of the sedimentation inclined plates 404 are jointly clamped with a support frame 405. And a guiding cone 403 protruding upward is integrally provided in the middle above the support frame 405. And the outer circle of the guiding cone 403 is tightly clamped with the bottom of the water inlet treatment cylinder 10. This structure makes the sedimentation inclined plates 404 capable of performing sedimentation treatment on the wastewater. And after the sediment falls into the spiral dirt cleaner 11, dirt cleaning treatment can be carried out. The support frame 405 can stably position the water inlet treatment cylinder 10 through the guiding cone 403. At the same time, the guiding cone 403 also guides the wastewater. And when cleaning the water inlet treatment cylinder 10, the impurities in the water inlet treatment cylinder 10 can be smoothly pushed onto the sedimentation inclined plates 404 through the guiding cone 403, and then dirt cleaning treatment is carried out through the spiral dirt cleaner 11. Ultrafiltration membranes 601 are evenly spaced and installed inside the secondary filtration tank 6. And diversion partition plates 13 are evenly spaced and provided at the bottoms of the secondary filtration tank 6 and the biological reaction tank 7. And air distribution pipes 703 are fixedly penetrated at intervals between the diversion partition plates 13 at the bottom of the biological reaction tank 7. The top of the secondary filtration tank 6 is connected to a water suction pipe 5 through a water pump, and the water suction pipe 5 is inserted into the water inlet buffer tank 12. This structure can introduce the preliminarily filtered wastewater into the secondary filtration tank 6 through the water suction pipe 5 so as to further filter the wastewater through the ultrafiltration membranes 601. And the wastewater after secondary filtration can directly flow into the biological reaction tank 7. The diversion partition plates 13 are evenly spaced and arranged at the bottoms of the secondary filtration tank 6 and the biological reaction tank 7, which can evenly distribute the wastewater into the biological reaction tank 7.Furthermore, it enables the biological filter media 702 to efficiently perform advanced wastewater treatment. A support plate 704 is clamped in the biological reaction tank 7, and the biological filter media 702 is arranged above the support plate 704. The air distribution pipe 703 provides the gas required for the biological filter media 702 to treat the wastewater. A second communication hole 701 is formed between the biological reaction tank 7 and the clean water tank 8, and the second communication hole 701 is located above the biological filter media 702. A drain pipe 801 is arranged on the side of the clean water tank 8. This structure allows the wastewater treated by the biological filter media 702 to flow into the clean water tank 8 through the second communication hole 701 and then be discharged through the drain pipe 801.

[0017] Working principle: When using this glass fiber wastewater advanced treatment device, first, the glass fiber wastewater is discharged into the inlet tank 3 through the inlet pipe 301. After the wastewater falls into the inlet treatment cylinder 10, the stirrer 9 stirs to accelerate the flow rate. Meanwhile, the chemical agent in the chemical agent addition tank 2 is added into the inlet tank 3 to quickly mix the wastewater with the agent, and the wastewater is filtered through the inlet filter screen 1001. The wastewater precipitates on the inclined settling plate 404. After the height of the wastewater rises to the position of the first communication hole 401, it flows into the inlet buffer tank 12. The annular limiting frame 402 is fixed in the inlet tank 3 through the side wall 4 of the inlet tank, and the guiding cone 403 is fixed on the inclined settling plate 404 through the support frame 405, so that the inlet treatment cylinder 10 is reliably positioned through the annular limiting frame 402 and the guiding cone 403. The water pump pumps the wastewater in the inlet buffer tank 12 into the secondary filtration tank 6 through the suction pipe 5, and the wastewater is secondarily filtered through the ultrafiltration element 601 to further remove impurities. Then, under the diversion of the diversion partition plate 13, the wastewater is evenly distributed into the biological reaction tank 7. The wastewater passes through the support plate 704 and reaches the biological filter media 702 for biological reaction treatment. The air distribution pipe 703 provides the required gas for the biological filter media 702. Then, the wastewater enters the clean water tank 8 through the second communication hole 701, and the glass fiber wastewater after advanced treatment is discharged through the drain pipe 801, completing the efficient purification of the main body 1 of the advanced treatment device. When the inlet tank 3 is being cleaned, the spiral dirt remover 11 can quickly discharge the sediment, making the cleaning convenient, thus completing a series of operations.
