| 摘 要： | 以含Fe3+、Cd2+的模拟废水为例,利用细菌絮凝剂和沸石两种吸附剂,分析了两种吸附剂单独及联合使用对模拟重金属废水的处理效果。结果表明,在处理高浓度含Fe3+废水时细菌絮凝剂表现出较好的吸附效果,在处理高浓度含Cd2+废水时,沸石处理效果明显,两种吸附剂联合处理废水可弥补各自吸附特性的不足,细菌絮凝剂能促进天然沸石颗粒物沉降。

| Abstract: | The aim of this paper is to analyze the effects of adsorption of Fe3+ and Cd2+ from simulated wastewater by using microbial flocculant and natural zeolite seperately and together.The results indicated that a good flocculation effect could be got in highly concentrated wastewater containing Fe3+ with microbial flocculant,while natural zeolite showed a better effect in highly concentrated wastewater containing Cd3+.The mixed adsorbent can compensate the respective defects in the adsorbing characteristics of individual adsorbent.Microbial flocculant can promote the deposition of natural zeolite particles. |
