摘要：

探索了一种以天然沸石为离子交换剂，以氯化钠水溶液为洗脱剂离子交换法除铵的新工艺。从试验结果来看，采用此方法处理天津同生化工厂钛酸钡生产过程中产生的洗涤废水（NH₄⁺含量为300×10^-6～400×10^-6）完全能达到国家环保要求，并且具有工艺简单、处理成本低的特点，从而为含铵废水处理提供了一条新途径。

Abstract:

This paper discusses a new method of using ion exchange to separate ammonia with natural zeolite. The natural zeolite is used as ion exchanger and the solution of sodium chloride is used as eluate. The experimental result has showed that the treated ammoniated wastewater, which comes from barium titunate production of Tianjin Tongsheng Chemincal Factory (NH⁴⁺ content:300×10⁶ ～400×10⁶ )can meet the environmental protection reguiuement of our country.
