| 摘 要： | 利用硫酸亚铁改性粉煤灰进行含磷废水的处理,探讨了pH值、粉煤灰投加量和吸附平衡时间对除磷效率的影响以及改性粉煤灰除磷的机理。实验结果表明,对于100mL含磷质量浓度为30.0 mg.L-1的溶液,改性粉煤灰除磷的最佳条件:pH 10,粉煤灰吸附容量1.0 mg.g-1,吸附平衡时间25 min;改性后的粉煤灰对磷的吸附符合Freundl-ich等温吸附公式。

| Abstract: | Removal of phosphorus from wastewater using fly ash modified by ferrous sulphate was studied.The effects of pH,modified fly ash dosage and adsorption time on removal rate of phosphorus were examined and the mechanism of phosphorus removal using modified fly ash was analyzed.The results showed that for 100mL solution containing 30.0 mg·L-1 phosphorus,the optimum pH value,modified fly ash dosage and adsorption time were 10,1.0 mg·g-1 and 25min respectively.Moreover,it was showed that adsorption of phosphorus on modified fly ash conformed to Freundlich adsorption isotherm. |
