摘要
采用碳酸钙、碳酸钠、硫酸及碳酸钠处理后再加硫酸等改性剂对粉煤灰进行改性处理;通过X-射线衍射分析研究其改性后的物相结构,并对几种废水进行吸附试验。研究探索出了粉煤灰及其改性后的吸附机理。并将其应用到了废水处理中,收到了较好的效果。
Fly ash properties is modified respectively by calcium carbonate, sodium carbonate and vitriol, as well as first fly ash is disposed by sodium carbonate and then activated by vitriol etc. We use X-ray diffraction to analysis the structure of modified fly ash and carry out the adsorption performance experiment on different waste water. We researched the mechanism of adsorption of original fly ash and modified fly ash., and get a comparatively better result through applying them to waste water treatment.
