Description

technical field [0001] The invention belongs to the field of tailing dense sewage treatment, and in particular relates to a composite magnetization flocculation thickening device. Background technique [0002] The thickening process of beneficiation tailings is affected by the low sedimentation rate of fine particles, which leads to the consumption of a large amount of electric energy for the transportation of low-concentration tailings, and at the same time, the amount of backwater utilization is reduced and the water quality is poor. The environment has been seriously polluted. As a relatively mature flocculation technology applied in the thickening of fine-grained pulp, although the sedimentation rate and thickening efficiency of tailings can be enhanced, the action of a single flocculation agent still cannot fully meet the force required for the settlement of fine particles in the pulp. At present, the single gravity field thickening device used in the existing tailings...

Problems solved by technology

[0002] The thickening process of beneficiation tailings is affected by the low sedimentation rate of fine particles, which leads to the consumption of a large amount of electric energy for the transportation of low-concentration tailings, and at the same time, the amount of backwater utilization is reduced and the water quality is poor. The environment has caused serious pollution

As a relatively mature flocculation technology applied in the thickening of fine-grained pulp, although it can enhance the sedimentation rate and thickening efficiency of tailings, the action of a single flocculation agent still cannot fully meet the force required for the settlement of fine particles in the pulp.

At present, the single gravity field thickening device used in the existing tailings thickening process still has problems such as uneven feeding, high degree of sedimentation turbulence, low flocculation and sedimentation rate, poor overflow water quality, and poor thickening effect.

[0003] Sewage magnetization treatment can effectively enhance the physical and chemical activity of water under the action of a strong external magnetic field, reduce the thickness of the hydration film on the surface of fine particles and the ζ potential value, and strengthen the separation of fine particles and water, as an economical and effective sewage treatment At present, it has not been well applied in the mine sewage and tailings thickening process, and the corresponding composite magnetized water treatment flocculation thickening device has yet to be developed and applied to mine tailings thickening and mine sewage treatment.
