利用钙型斜发沸石处理氨氮废水

介绍了用钙型斜发沸石处理氨氮废水的方法，研究了钙型斜发沸石对氨氮废水的吸附性能、洗脱蒸氨曲线和斜发沸石在氢氧化钙溶液中的损失。实验结果表明：钙型斜发沸石对铵离子具有很高的选择性和离子交换能力。可长期在氢氧化钙溶液中使用。该方法具有投资低、高效、节能、操作稳定等特点。在处理废水的同时又可回收氨，可创造一定的经济效益。具有较好的应用价值。

Removal of NH_4-N Wastewater by Ca~(2 )-Clinoptilolite

The removal of ammonia from wastewater by Ca~(2 )-clinoptilolite is introduced togather with some discussion of the capacity of absorption of Ca~(2 )- clinoptilolite in the NH_3-N wastewater, the isotherm of elution process and the Ca~(2 )- clinoptilolite's lose in the solution of Ca(OH)_2. The experimental results show that Ca~(2 )- clinoptilolite has very high alternative and ion exchange ability to the ammonium ion. It can use in the solution of calcium hydroxide for a long time. The process has the characteristics of low investment, high-efficiency, energy-conservation and operating steadily, etc., which can also recover ammonia while treating wastewater. So using this method can create economic benefits and has better value in the realities.
