| description | The adsorption efficiency of silica sand was greatly improved by coating and functionalized silica sand. The static and dynamic adsorption tests of phosphorus substances in phosphorus-containing wastewater were carried out, and the static and dynamic adsorption effects of amino-functional silica sand were analyzed. The adsorption mechanism of amino-functional silica sand on phosphorus was analyzed by FT-IR test.The results showed when the initial solution concentration is 0.5 g/L, the adsorption temperature is 60 ℃, the diameter of adsorbent particles is 0.5～1.0 mm, the adsorption time is 16 h, and the content of amino-functionalized silica sand is 8 g/L. The static adsorption effect is the best. The moving rate of amino-functionalized silica sand is set as 4.5 cm/h, the initial solution concentration is set as 1.0 g/L, the height of adsorption layer is set as 60 cm, and the flow rate of wastewater is set as 0.15 L/h, the dynamic adsorption effect is best and economical. |
