摘要
以粉煤灰为吸附剂,应用于去除废水中的磷,探讨了吸附时间、吸附剂用量、磷酸盐初始浓度对吸附效率的影响。并对粉煤灰用不同浓度的硫酸进行了改性,改性后的粉煤灰对磷酸盐的去除率大幅度提高,达90%以上。
Phosphorus wastewater was treated by fly ash adsorbent,the influence of adsorption time,adsorbent dose,the phosphate initial concentrations on the removal rate were discussed.Fly ash were modified by different concentrations sulfuric acid.The removal rate increases a lot using modified fly ash as adsorbent
