[0033] The degreasing water collection tank 1 is connected to the waste acid via a pipeline.

[0034] The first flocculation sedimentation tank is equipped with a first flocculant inlet pipe and a first alkali inlet pipe at its top. Inside the first flocculation sedimentation tank, there are a first baffle and a second baffle, which divide the tank into a first reaction zone, a first sedimentation zone, and a second sedimentation zone. The height of the first and second baffles is less than the height of the first flocculation sedimentation tank, allowing the solution in the first reaction zone to enter the first sedimentation zone, and the solution in the first sedimentation zone to flow into the second sedimentation zone. The first flocculant inlet pipe and the first alkali inlet pipe enter the reaction zone of the first flocculation sedimentation tank. The bottom of the first flocculation sedimentation tank is connected to the sludge tank 12 via a pipe.

[0035] The first treatment assembly includes a first pH adjustment tank 6 and a first sand filter tank 7, which are connected sequentially by pipes. A second discharge pipe is provided on one side of the first sand filter tank 7. A second flocculant inlet pipe and a second alkali inlet pipe are provided above the second flocculation sedimentation tank.

[0036] The second flocculation sedimentation tank is equipped with a third and a fourth baffle, which divide the tank into a second reaction zone, a third sedimentation zone, and a fourth sedimentation zone. The height of the third and fourth baffles is less than the height of the second flocculation sedimentation tank, allowing the solution in the second reaction zone to enter the third sedimentation zone, and the solution in the third sedimentation zone to flow into the fourth sedimentation zone. A second flocculant inlet pipe and a second alkali inlet pipe enter the reaction zone of the second flocculation sedimentation tank. The bottom of the second flocculation sedimentation tank is connected to the sludge tank 12 via a pipe.

[0037] The second regulating assembly includes a second pH regulating tank 8, a second sand filter tank 9, and an RO membrane water treatment system 13.

The filter press 14 adopts existing technology and was purchased from Yuzhou Hengguan Filtration Equipment Co., Ltd.

[0038] The production of welding wire mainly discharges four types of wastewater, including degreasing wastewater, wire washing wastewater, waste acid, and plating solution.

[0039] Degreasing water treatment process: The production line discharges wastewater into degreasing water collection tank 1. Since the pH value of the degreasing wastewater is alkaline, in order to facilitate subsequent treatment, waste acid in the waste acid collection tank is also added to the degreasing water according to the pH value (the addition of waste acid can also play a role in demulsification).

[0040] After adjustment, the degreasing water is pumped into the first flocculation sedimentation tank for sedimentation treatment. During the process of pumping into the first flocculation sedimentation tank, alkali is added according to the pH value, and flocculant is added at the same time to cause the small sludge lumps to flocculate and settle. After sedimentation, the supernatant enters the first pH adjustment tank 6 for pH adjustment. After adjustment, the wastewater enters the first sand filter tank for suspended solids filtration and is then discharged. The settled sludge enters the sludge tank 12, and the sludge tank 12 pumps the sludge into the filter press 14. The product water of the filter press 14 flows back to the degreasing water tank, and the sludge is discharged through the sludge discharge pipe.

[0041] Wool washing wastewater treatment process: The production line discharges molten wool washing wastewater into molten wool washing wastewater collection tank 10. The wastewater has an acidic pH. During the second flocculation and sedimentation process, alkali and flocculant are added. After sedimentation, the supernatant enters the second pH adjustment tank for pH adjustment. After adjustment, the wastewater enters the second sand filter tank for suspended solids filtration and is then discharged into the RO membrane water treatment system for further treatment. The purified water produced by the RO membrane is collected and flows into the workshop for use, while the wastewater is discharged externally.

[0042] Plating solution: The production line discharges waste plating solution into plating solution collection tank 3, and then into plating solution filtration equipment 4 and plating solution extraction equipment 5. After passing through plating solution extraction equipment 5, the purified liquid is returned to the workshop for continued use, and the waste liquid is pumped into degreasing water collection tank 1.
