| Abstract: |
| Ammonia nitrogen wastewater from in-situ leaching ion-adsorption type rare earths mineral was treated by contact membrane deamination method. The principle, process, characteristics, and main equipment parameters of contact membrane deamination method were introduced. Effluent ammonia nitrogen concentration of industrial wastewater from ion-adsorption type rare earths mineral applying this method is 15 mg/L below with ammonia nitrogen removal rate of 98% above, which meets the industrial wastewater discharge standards. This method has the advantages of high removal efficiency, simple and convenient operation, small occupied area, good stability and portable mobility. |
