The Phosphorus-Adsorption Capacity and Influencing Factors Study of Zeolite

Abstract:

Because of the poor phosphorus removal of nature zeolite, the best modification method was prepared as follows : First, natural zeolite was soaked in 1mol/L NaOH solution on dynamic condition at 35°C for 1 hour. After washed with deionied water, it was soaked in 20% MgCl2 solution on dynamic condition at 35°C for 48h, then was roasted at 500°C in a muffle furnace for 3h and in the end cooled to normal temperature.Based on this, the capacity of the modified zeolites was studied under different conditions of contact time, dosage and temperature in order to examine dephophorization ability of modified zeolite. The results from batch experiment suggest that the modified zeolite has a more P sorption capacity possibly due to the hydrated magnesium on or in the modified zeolite.
