Background technique

There are many hydrophilic groups and clay substances in industrial wastewater in my country, and the suspended particles are relatively fine, and the performance of flocculation and settlement is relatively poor. Therefore, the method of magnetic flocculation was introduced. Magnetic flocculation is a sewage treatment process in which magnetic particles are added to traditional flocculation agents and magnetic fields are used to accelerate precipitation. Compared with conventional flocculation, magnetic flocculation is faster and more thorough, which is equivalent to increasing the processing capacity and reducing the processing cost. While using the magnetic flocculant's super magnetic properties and high-efficiency flocculation and adsorption characteristics to treat wastewater, it is a significant operation to magnetically separate the magnetic flocculant and recycle magnetic substances, which not only reduces the dosage of chemicals but also The amount of sludge produced by flocculation is reduced to protect the environment.

For the flocculation of industrial wastewater, the existing flocculation methods are difficult to settle the suspended particles in industrial wastewater, and a large amount of residual sludge is generated during the treatment process, which increases the secondary pollution of the environment.
