| 摘 要： | 以二级出水中氨氮为处理对象,以天然斜发沸石、脱磁钢渣和泥炭为吸附剂,考察不同影响因素对天然斜发沸石、脱磁钢渣和泥炭吸附氨氮的影响。分析了pH值对填料吸附的影响,同时考察了这3种填料对氨氮的最大吸附容量、时间对填料吸附氨氮的影响以及不同水力条件下这3种填料对二级出水中氨氮的柱穿透试验。结果表明:斜发沸石对二级出水中的氨氮去除效果最好,泥炭其次,脱磁钢渣最差。

| Abstract: | The removal of ammonia nitrogen from secondary effluent by clinoptilolite,demagnetized steel slag and peat was studied,the effect of pH value on the three fillers was analyzed,the effects of maximum adsorption capacity and time of three fillers Absorbing ammonia nitrogen were investigated,and the effects of three fillers on removing ammonia nitrogen under different hydraulic conditions were tested.The results showed that the removal effect of clinoptilolite was the best,then peat,while that of demagnetized steel slag was the worst. |
