Abstract

The invention provides processing equipment for separating waste water by superconducting magnet, comprising a magnetic seed and flocculating agent feeding machine, a mixer and a superconducting magnetic coolant separator; wherein the magnetic seed and flocculating agent feeding machine is used for feeding magnetic seeds and flocculating agent to the mixer; the mixer is connected with a water pipe and used for fully mixing the magnetic seeds and flocculating agent with the waste water; one end of the superconducting magnetic coolant separator is connected with the mixer by a pipeline and the other end thereof is connected with a water outlet pipe, the superconducting magnetic coolant separator is provided with a filtration device made from ferrite stainless steel material. In the invention, the magnetic seeds are added in advance, so that nonmagnetic harmful substances can be fully combined with the magnetic seeds, thus realizing separation and purification of the waste water by superconducting magnet and being widely applied to process industrial and domestic waste water. Meanwhile, the invention has the advantages of low cost, high efficiency, small power consumption and unattended automatic operation.

Description

technical field

[0001] The invention belongs to the field of resource and environment protection, in particular, the invention relates to a superconducting magnetic separation device for wastewater treatment. Background technique

[0002] At present, the industrial wastewater treatment methods widely used in China mainly include chemical methods and biochemical methods. Chemical methods mainly include precipitation, filtration, neutralization and decolorization. Biochemical methods mainly include biological contact oxidation-coagulation sedimentation method, biological filter-oxidation ditch and activated sludge method, pure oxygen activated sludge method, oxidation pond method, etc. However, the current practical chemical and biochemical methods have problems such as large investment, high operating cost, long reaction time, large footprint, complex process, low efficiency, and high energy consumption. Especially in paper mill wastewater treatment, these problems are more...
