Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sedimentation and separation device for mine wastewater. Background Technology

[0002] Mine wastewater contains a large amount of suspended solids, including coal slime, rock powder, and silt. If these particles directly enter subsequent treatment units, they will clog equipment pipelines and increase operating and maintenance costs. Therefore, mine wastewater needs to be effectively treated. A common treatment method is to add treatment agents to the wastewater and allow it to settle. Finally, the sediment is separated. The traditional sedimentation separation method uses an external water pump to suck out the water on the sediment surface. However, this active suction method disturbs the sediment during sedimentation separation, causing impurities in the sediment to start flowing again, which affects the sedimentation separation effect and reduces the wastewater treatment efficiency.

[0003] Therefore, we propose a mine wastewater sedimentation and separation device to solve the above problems. Utility Model Content
