Example Embodiment
[0013] The present invention will be further described in detail below with reference to specific embodiments with accompanying drawings. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.
[0014] A process for treating and recycling ammonium chloride rare earth wastewater, the specific steps and working conditions are as follows:
[0015] (1) The suspension after the sedimentation treatment is input into the DEP microfiltration, and the working pressure is 1 to 2 bar to remove the solid particles contained in the suspension, and the concentrate is recycled to the sedimentation again, and the treated The liquid of the solid suspension is input into the DEP nanofiltration group;
[0016] (2) After many cycles, the concentrated kerosene emulsion containing solid particles will be input to the DEP-DEEP-BED microfiltration process to separate the kerosene emulsion from the suspension. The working princ...
