| 摘 要： | 为了研究胶体和固体颗粒同时存在时高浓度氨氮的吸附分配特征,根据天津市含水介质的结构和组成,选择3种代表性的含水介质,系统测定了不同含水介质中胶体和固体颗粒对氨氮吸附的动力学曲线和吸附等温线。研究结果表明:当胶体和固体颗粒同时存在时,不同含水介质胶体对氨氮吸附的动力学曲线均符合对数递减函数,而固体颗粒对氨氮的吸附量随时间增加,变化幅度很小;胶体对氨氮的吸附量远大于固体颗粒。胶体和固体颗粒对高浓度氨氮的吸附等温式分别为Freundlich方程和线性方程。粉砂胶体和固体颗粒对氨氮的吸附能力大于中砂和粉土。

| Abstract: | Combined with field survey information,beach experiments with three representative water-bearing media in the Tianjin coastal plain have been conducted to elucidate the adsorption distribution of ammonia-nitrogen between colloid and solid particles.In addition,dynamic curves and isotherms of ammonia-nitrogen adsorption on the colloid and solid particles in different water-bearing media have been determined.The research results show that adsorption kinetics of ammonia-nitrogen on colloids in different water-... |
