| 摘 要： | 研究了高效除磷材料（EPRC）对磷素的吸附特性，考察了投加量、初始浓度、初始pH值、粒径等对EPRC吸附性能的影响，分析了不同条件下EPRC的吸附过程。结果表明，最佳投加量为3.5 g/250 mL时，去除率达91.07%，出水TP浓度为0.45 mg/L。随着粒径减小，EPRC对磷素的吸附量增大，吸附平衡时间缩短。溶液初始pH值在碱性条件下，吸附容量变大。

| Abstract: | An efficient phosphorus removal composite (EPRC) from fly ash and steel slag was made. The adsorption characteristic of EPRC on phosphate removal was studied. The effects of dosage, phosphorus concentration, initial pH value, and particle size of EPRC on the phosphorus adsorption were investigated. The results showed that when the best dosage is 3.5 g/250 mL, the concentration of phosphorus in the effluent water after the treatment was 0.45 mg/L. The adsorption capacity of EPRC to phosphorus was increasing with decreasing the particle size of EPRC. The adsorption capacity will be bigger when the initial pH value of the aqueous solution was basic. |
