| 摘 要： | 采用电化学方法,以轻度污染的温榆河河水为研究对象,考察了电化学方法对微污染地表水中氨氮的去除效果,探讨极板间距、反应时间以及板间电压对氨氮去除的影响。研究表明:反应时间为10min,板间距为1.0cm,板间电压为11V时,该方法对去除微污染水中氨氮有较好的处理效果,对氨氮的去除由原水的8～36mg/L降至2.4～11mg/L,去除率能达到70%以上,同时总氮的去除与氨氮去除呈现良好的相关性。

| Abstract: | In this study,electrochemical process was used to treat lightly polluted water from Wenyu River. The ammonia removal effect was observed and the effects of plate electrode space,reaction time and voltage between plate electrodes on ammonia removal were discussed. The results showed that ammonia was removed efficiently by electrochemical process on the conditions of 10 min of active time,1.0 cm of plate electrode space and 11 V of voltage between plate electrodes,and ammonia removal efficiency was above 70% ... |
