摘要
通过对失去干燥性能的分子筛废弃物进行再生改性，开发出了一种新型的用于脱除水中氨氮的离子交换剂。研究了水中共存阳离子对氨氮去除率的影响，测定了交换容量，研究了交换时间、温度及再生方法等条件与氨氮去除率的关系，并对交换剂的性能与结构进行了关联，优化了该交换剂用于处理氨氮废水的操作条件。
A new type of ion exchanger for removing ammonianitrogen from wastewater was developed by regenerating and modifying the waste sieve sorbent that had lost its drying performance.The influence of coexistence of cations in wastewater on ammonianitrogen removal efficiency and the relation between some conditions(such as contact time,temperature and regeneration methods)and ammonia removal efficiency were studied;the exchange capacity was measured;the relationship between performance and stracture of the exchanger was explored and the operation conditions for applying the exchanger to the treatment of ammonianitrogencontaining wasterwater were optimized.
