[0002] At present, the treatment of wastewater used for rare earth NdFeB is divided into eight steps: waste crushing, magnetic separation, pickling, dissolution, extraction, separation, precipitation, and smelting. The precipitation process is to precipitate the separated rare earth elements through chemical reactions to obtain pure NdFeB metal.

[0003] In the existing wastewater treatment equipment for rare earth NdFeB, when the wastewater is subjected to sedimentation treatment, after the NdFeB metal is precipitated, the wastewater on the upper layer needs to be discharged to facilitate the subsequent removal of the NdFeB metal. When the wastewater is discharged, due to the different heights of the NdFeB metal precipitation each time, most of the wastewater will remain after discharge, and the discharge needs to be adjusted twice, which is very inconvenient.
