[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. The main pollutants exceeding the standards in desulfurization wastewater are suspended solids, pH value, heavy metal ions, and fluorides, which need to be treated before being discharged into the environment.

Then, the solenoid valve 33 is opened, and the wastewater mixed with flocculant is discharged into the filter cylinder 19 through the outlet 4. At the same time, the rotation of the third bevel gear 18 drives the second rotating shaft 30. The second rotating shaft 30 is connected to the second fixed... The second shaft 30 rotates in coordination with the second synchronous pulley 29, which in turn drives the first synchronous pulley 27 via the synchronous belt 28. The first synchronous pulley 27 drives the first shaft 25 to rotate, and the first shaft 25 rotates while driving the second gear 24. The second gear 24 drives the first gear 23, which in turn drives the filter cylinder 19. As the filter cylinder 19 rotates, it drives the auger blades 21, which continuously push and transport the sediment. The wastewater enters the filter box 2 through the filter holes 20 inside the filter cylinder 19, which can separate the wastewater from the sediment inside the wastewater. This is beneficial to the desulfurization effect of the wastewater and solves the problem that although the existing desulfurization treatment device for sulfur-containing industrial wastewater uses flocculants to precipitate impurities in the wastewater, it does not have the function of separating the settled impurities from the water, thus affecting the desulfurization effect of the wastewater.
