The basic principle of magnetic separation sewage treatment equipment is to add magnetic particles to the traditional flocculation sedimentation process. Through steps such as flocculation, attraction, adhesion, charge adsorption, bridging, and net capture, insoluble pollutants in the water, such as algae, fine suspended solids, colloids, and bacteria, are effectively combined with magnetic powder. This forms a high-density flocculation body, which achieves rapid heterogeneous sedimentation and separation through gravity and inclined tube sedimentation principles. The sediment sludge is pumped back to the magnetic powder sludge separation system for recovery, allowing the magnetic powder to be recycled. The separated sludge is discharged into the sludge tank for dehydration treatment.

The difference between magnetic separation sewage treatment equipment and traditional sewage treatment equipment lies in its short processing time; the entire treatment process can be completed in 10-15 minutes. This also results in very low energy consumption for the equipment. The effluent water quality can achieve SS below 5mg/L and TP below 0.3mg/L. It also has excellent removal effects on COD, BOD, permanganate index, bacteria, and other pollutants in wastewater. Additionally, it has strong resistance to impact loads and can operate stably even under high-concentration and high-energy-consumption conditions. Low investment per ton of water, small footprint, and low operating costs are the advantages of magnetic separation sewage treatment equipment.

Applications of magnetic separation sewage treatment equipment:

(1) Particularly suitable for the expansion and upgrading of sewage treatment plants;

(2) Urban domestic sewage treatment, made into mobile terminals for mobile treatment of wastewater, effectively addressing issues such as dispersed urban wastewater and incomplete pipeline networks.

(3) Used for the remediation of groundwater such as lakes and rivers, removing algae from the water, significantly reducing the permanganate index in the water, effectively controlling water eutrophication, and improving water quality.

(4) Used for the treatment of petroleum wastewater, papermaking wastewater, chemical wastewater, and high-phosphorus industrial wastewater.

Regarding the working principle of magnetic separation sewage treatment equipment, Suzhou Biyuan Environmental Protection has summarized this much for now.
