Flocculation sedimentation tanks and inclined tube sedimentation tanks have significant differences in working principles, structural characteristics and application scenarios.
1. Working principle
Flocculation sedimentation tank: mainly achieves the aggregation and sedimentation of suspended matter through physical and chemical effects. The flocculation equipment is equipped with a diversion mechanism inside, which changes the boundary conditions of turbulent flow, increases turbulence, and forms small vortices with high proportion, high intensity and high density, thereby promoting the aggregation and sedimentation of suspended matter
Inclined tube sedimentation tank: Use gravity to settle suspended matter. Dense inclined tubes or inclined plates are set in the sedimentation area to allow suspended impurities in the water to settle in the inclined plates or inclined tubes. The water flows upward along the inclined plates or inclined tubes, and the separated sludge slides down to the bottom of the pool along the inclined tubes (plates) under the action of gravity
2. Structural features Flocculation sedimentation tank:
The structure includes a diversion mechanism, baffles and fins. The cross section of the diversion mechanism is star-shaped, with 1 to 3 fins welded on the partition. The overall structure is a box-type structure, assembled by welding, with high strength and beautiful appearance.
Inclined tube sedimentation tank : It is equipped with dense inclined tubes or inclined plates. Water flows up along the inclined plates or inclined tubes. The separated sludge slides down along the inclined tubes (plates) to the bottom of the pool under the action of gravity and then discharged in a centralized manner.
3. Application scenarios
Flocculation sedimentation tank : It is suitable for treating electroplating wastewater, coal mine and mineral processing wastewater, printing and dyeing, bleaching and dyeing and other wastewaters. For electroplating wastewater, the removal rate is above 90%; for coal mine and mineral processing wastewater, the turbidity removal effect is significant; for printing and dyeing and bleaching and dyeing wastewater, the chroma and COD removal rates are high.
Inclined tube sedimentation tank : It is suitable for the treatment of various industrial wastewaters, such as electroplating wastewater, coal mine and mineral processing wastewater, printing and dyeing, bleaching and dyeing and other wastewaters. Its high treatment efficiency and low investment cost make it widely used in industrial wastewater treatment.
