精细化学品脱除AS流程含氨生产水中氨氮的研究

Study on the removal of NH3-N from the ammonia water in AS process using fine chemicals

笔者选取一种精细化学品处理AS流程含氨生产水，采用“空气吹脱法”对武钢焦化厂AS流程中含氨生产水进行氨氮脱除，研究了反应温度、pH、反应时间、精细化学品的投加量等因素对氨氮去除效果的影响，得出最佳反应条件，提高了脱氨氮效率，从而为焦化废水处理提供新的有效途径。

The purpose of this study was to choose a fine chemical to efficiently remove ammonia nitrogen from the ammonia water in AS Process, which provides a new available approach to treat coking wastewater. The experiment adopted ＂Air Stripping and Adsorption＂ to remove ammonia nitrogen from the ammonia water, and studied the reaction temperature （ T/℃ ）, pH, the time of stripping（ t/min）, the dosage of the fine chemical, and so on. Got the optium reaetion condition, improved the removing effiency of ammonia and nitrogen provide a new effective way to treat the Coking wastewater.
