| 摘 要： | 对粉煤灰的基本性质、吸附特性和处理废水的机理作了详细介绍,同时根据粉煤灰的物理和化学吸附性来研究对生活污水的吸附效果,分析其影响吸附性的主要因素.通过对生活污水中主要项目(COD和磷)的测定得出结论:粉煤灰经12h后吸附趋于稳定,达到吸附平衡,灰水比在1∶10时吸附效果最好, pH值控制在7～8效果最好.最后对粉煤灰的进一步研究利用提出了建议.

| Abstract: | The basic property,adsorption characteristics and mechanism of treating waste water of pulverized-coal ash were presented in detail.The physical and chemical adsorptive properties of pulverized-coal ash were used to study adsorptive effect on domestic sewage and analyze main factors to affect the adsorptivity.Main items(COD and phosphorus)in domestic sewage were measured.The test results showed that adsorption of the coal ash trended towards stability and research adsorption equilibrium after 12 hours.Adsor... |
