A method for recovering rare earth and rare earth ammonia discharged from the standard production wastewater

The present invention provides a method of rare earth and ammonia is recovered from the discharge standards wastewater rare earth production, which mainly comprises a rare earth wastewater purification, recovery of rare earths, rare earth wastewater purification and recycling ammonia treatment step. The present invention is a rare-earth ion-exchange resin having a high recovery of economic value, directly and then various concentrations of ammonia nitrogen wastewater treatment of the wastewater produced by the ammonia gas-liquid separation. This process is simple, low cost, small investment, significant treatment effect, to ensure full compliance ammonia emissions, ammonia absorbing liquid may also be recycled to the process the rare earth mining, no secondary pollution problem, a rare earth wastewater from efficient, rare earths and economic method of treating ammonia recovery.
