[0035] Operation process: Before using the device, first introduce the wastewater to be treated into the desulfurization tank 4 through the liquid inlet 5. First, drive the stirring blades 7 to rotate through the stirring motor 6 to make the wastewater fully react with the treatment agent and flow into the sedimentation tank 8. The mounting blocks 301 are fixed on the sides of the water purification tank 9 and the desulfurization tank 4 close to the sedimentation tank 8. The mounting blocks 301 are fixedly connected through the guide rods 302.

[0037] The present invention also provides a wastewater desulfurization treatment method applied to wastewater treatment equipment, which further includes the following steps:

[0038] The wastewater first enters the desulfurization chamber 4 through the liquid inlet 5. Before entering the sedimentation chamber 8, it usually needs to be pretreated. The stirring motor 6 drives the stirring blades 7 to fully mix and react the wastewater with the treatment agent.

[0039] After the wastewater enters the sedimentation chamber 8, the solid particles and other sediments therein start to settle to the bottom.
