| 摘 要： | 以氨氮为处理对象,通过杯罐试验考察了分别用盐酸、氢氧化钠、氯化钠改性的膨润土、沸石、粉煤灰对氨氮的去除效果,初步遴选较优的改性吸附剂。试验结果表明:在水温25℃,振荡频率100 r/min,吸附时间2 h的条件下,改性后的吸附剂对氨氮去除率都有一定提高,氯化钠改性沸石对氨氮的去除效果最佳。

| Abstract: | Taking ammonia nitrogen as processing object,the paper examined removal efficiency of bentonite,zeolite and flyash respectively modified by hydrochloric acid,sodium hydroxide,sodium chloride to the ammonia nitrogen and preliminarily selected the better modified absorbents through jar test.Test results showed that under the conditions of the water temperature 25 ℃,oscillation frequency 100r/min,adsorption time 2h,removal rate of the modified absorbents to the ammonia nitrogen had certain enhancement,the removal effect of sodium chloride zeolite to ammonia nitrogen was the best. |
