It is not only carried out at the same time electric flocculation, the flocculation treatment of magnetic flocculation in reactive tank, reduces flocculated complexity respectively, hence it is evident that improve
Flocculated effect, and magnetic flocculation and Magneto separate are realized to control absorption and the release of magnetic powder by electromagnetic induction device,
It is not only conveniently operated easily controllable, but also the impurity in sewage can be efficiently separated, magnetic powder and magnetic powder separation is added without additional
Processing equipment, magnetic powder can be recycled, and magnetic flocculation and the speed and efficiency of Magneto separate are substantially increased.
In this as it can be seen that the present invention realizes electric flocculation, magnetic flocculation and Magneto separate integration in the different phase of same device,
Investment cost is low, and operation operation is easy, can save occupation of land, substantially increase flocculating effect and sinking speed；The present invention can be direct
For the transformation of original electric flocculation equipment in Practical Project, installation is convenient, and pond and magnetic powder separation are added without increasing magnetic powder
Pond can achieve the purpose that propose mark transformation；Magnetic powder is added in the present invention when start to process sewage, sewage is in magnetic powder, wadding
Flco is formed under the action of solidifying agent, electromagnetic induction device is then opened and adsorbs the flco combined with magnetic powder, solve magnetic flocculation
Magnetic powder recycles problem, increases the rate of recovery of magnetic powder, simplifies the process that magnetic powder is added and detached, improve the speed of wastewater treatment
Rate；Stability and adaptability of the present invention is strong, can bear water quality and the water variation of bigger, it is useless to can be directly used for processing plating
The higher industrial wastewater of the content of beary metal such as water, desulfurization wastewater, mine wastewater has wide development space and market prospects.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification made by all within the spirits and principles of the present invention,
