Microwave-Ferrous Sulfate Modified Activated Carbon Adsorption Study on Phosphorus Removal

Using microwave-ferrous sulfate modified activated carbon adsorption manner to remove the high concentration of phosphorus in wastewater. The power of microwave, the concentration of ferrous sulfate and reaction time on phosphorus removal were studied. When the power of microwave was 425W, the concentration of ferrous sulfate was 0.1mol/L, reaction time was 50 min, the removal rate of TP reaches 95.67%, the treated effluent TP can be dropped to 0.48mg/L, the TP can reaches the first effluent standard of TP in the comprehensive wastewater discharge standard(GB8978-1996). Microwave-ferrous sulfate modified activated carbon is adapted to treat high concentration phosphorus in the wastewater.
