摘　　要：采用脱氨剂去除稀土废水氨氮,并对处理的影响因素进行了探讨。试验结果表明,投加量脱氨剂为1000 mg/L、反应时间为60min、反应pH为9时,可将稀土废水中的NH3-N从14436mg/L降低到2435mg/L,去除率达到83.13%,并可大大降低处理成本,因此,该方法可以作为稀土废水的前处理方法。The rare earth wastewater was treated by the deaminase agent and the influence factors on NH3-N removal were investigated in this paper.Results showed that content of NH3-N in the wastwater decreased from 14436.00mg/L to 2434.86mg/L,and the removal rate reached above 83.13% when the added amount of deaminase agent was 1000mg/L,the reaction time was 60 min and pH of reaction was 9.The treatment cost was greatly reduced,so this method could be used in the pretreatment of RE wastewater.
