摘要
从研究硅藻土的微观结构和物理化学特性着手 ,通过对比实验 ,讨论硅藻土的改性及其对工业废水降氟效果的影响 .结果表明 ,改性后的硅藻土孔体积和比表面积增大 ,而堆积密度减少 ,同时碱金属或碱土金属被结合在硅藻土的缺损表面上 ,为吸附氟提供了更好的条件 ,可以显著地提高去氟效果 。
Property_modified diatomite was used to remove fluorine in industrial wastewater. The micro_structure and physicochemical characteristics of Shengxian diatomite were studied before and after the property modification. The results show that the hole volume and the ratio of surface area of the property_modified diatomite are increased, and its pile density is decreased. As a result, the ability of property_modified diatomite removing fluorine in industrial waster water by its absorption and chemical reaction with fluorine is significantly increased.
