Phosphorus Dynamic Adsorption from Wastewater by Iron-Oxide-Coated-Zeolite

Abstract:

In this paper, Iron-Oxide-Coated-Zeolite has been prepared by using natural zeolite and ferric nitrate. The absorbing effect of IOCZ on phosphorus is also investigated, including the filler height, the flow rate and initial phosphorus concentration on breakthrough curve were studied. The results show that IOCZ as an adsorbent can effectively remove the phosphorus from the wastewater. When the filler height and the initial phosphorus concentration increased, the adsorption effect increased and the breakthrough time reduced. The best filler height is 30cm. The higher the initial phosphorus concentration is, the less the processing water is. Column experiment was used for advanced treatment and it can process substantial wastewater, and then makes the effluent phosphorus concentration meet the national emission standards. When the regenerated solution was trickled into the solution about 5min, almost all of the phosphorus separated from the IOCZ.
