改性膨润土去除含磷废水实验研究

摘要：本试验研究将三氯化铝作为改性剂，用天然膨润土作为载体，使三价铝离子在膨润土内部骨架空间进行离子交换制成改性膨润土滤料。改性滤料的表面态和表面能均不同于未改性滤料，变性过程使它们的表面特性发生了变化，比表面积增加，表面活性吸附位和活性吸附点增多，表面吸附能力增强。笔者通过大量试验，对改性滤料不同试验条件其去除含磷废水的效果进行了研究和分析。

Study on Phosphorus removal by Coated filter media of Bentonite

This experiment and research take AlCl3 as a denaturant,using natural bentonite as a carrier,causes Al3+ come into the bentonite's internal skeleton space doing ion exchange to make impregnation variability bentonite filter.Modified filter surface states and surface energy are different from those of unmodified filter,denaturation makes their surface characteristics changed,the surface area increased,surface active adsorption sites and active adsorption points increased too,surface adsorption capability str...
