摘要
利用气体分离膜装置脱除脱硫废水中的氨氮,脱除率最高可达到99%以上,脱除率与运行的时间及废水的p H有关。该装置对废水预处理要求不高,工艺流程简单,系统常压运行,运行成本低,操作方便。
Using gas separation membrane device to remove ammonia nitrogen from wastewater can achieve a removal rate of ammonia nitrogen reaching up to 99%, which de-pends on the operation time and pH value of the wastewater. The device has the advantages of low requirement on wastewater pretreatment, simple process flow, system operation under normal pressure, low operation cost and convenient operation.
