| 中文摘要 | Phosphorus (P) is regarded to be one of the most important causes for the eutrophication in freshwater bodies. The removal technique of P from wastewater and water-bodies has become a hot topic in the world. In this paper, used cement was chosen as the experimental material, and the effects of main influencing factors, such as dosage, temperature, pH and vibration time, on P adsorption characteristics were evaluated. Results showed that P can be effectively removed using cement powders, and the optimal cement dosages were 0.6, 1.4 and 5 g/L in the presence of 5, 10 and 50 mg phosphate concentration per L, respectively. A significant linear correlation (R-2 = 0.9872) between P concentration and optimal cement dosage was observed. The optimal conditions were determined to be: cement dosage 3 g/L, temperature 25 degrees C and vibration time 8 h. The maximum adsorptive capacity of cement was 7.93 mg P/g with an initial phosphate concentration of 25 mg P/L. |
