Removal of Phosphate Anions from Wastewater by Wasted Low Grade Iron Ore with High Phosphorus Adsorbent

Article Preview

Abstract:

Low grade ore iron with high phosphorus(LGIOWHP), an industrial solid waste is used as an adsorbent to remove phosphate anions from wastewater. The effects of initial pH, stirring speed, reaction time, reaction temperature and adsorbent dosage on the phosphate removal rate were investigated. The results show that the phosphate removal rate exceed 99% under the optimal conditions. After phosphate removal reaction, the phosphate concentrations completely meet the requirement of national discharge standards of the second category pollution (GB 8978- 1996).
