摘要
采用天然麦壳为吸附剂可吸附废水中的氨氮。考察了接触时间、pH值、麦壳投加量、初始氨氮浓度及温度对吸附效果的影响;应用吸附等温方程、吸附动力学方程及吸附热力学方程对实验数据进行拟合,以期明确麦壳吸附水体氨氮的机理,为麦壳脱氮的实际应用提供理论依据。
The natural wheat husks can used as an adsorbent to remove ammonia-nitrogen from wastewater. This paper studies the influence of contact time, pH value, husks dosage, initial concentration of ammonia-nitrogen and temperature on the adsorption efficiency, and by using the adsorption isotherm equation, adsorption dynamical equation and adsorption thermodynamical equation,fits the experimental data for making clear the mechanism of husks＇ adsorbability for ammonia- nitrogen in water and providing a theoretical basis for the practical application of husks＇ denitrification.
