Study of phosphorus removal composite prepared by industrial waste residue
工业废渣基除磷材料的静态吸附研究

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.
