Paper Title:
Pilot Study on Removal and Recovery of Nitrogen and Phosphorus in Human Urine by Crystallization of Magnesium Ammonium Phosphate
  Abstract

Laboratory-scale tests for removal and recovery of nitrogen and phosphorus in human urine were conducted by magnesium ammonium phosphate precipitation (MAP) method. Proper Na2HPO4•12H2O as a phosphorus source and MgCl2•6H2O as a magnesium source were added to adjust the ratio of Mg2+, NH4+and PO43-. The effects of initial pH, (Mg2+): n (NH4+), n (PO43-) : n (NH4+), temperature, reaction time and stirring speed on removal and recovery of nitrogen and phosphorus in urine were studied by MAP method. Results showed that the optimum experimental conditions were at room temperature, pH, the molar ratio of Mg2+:PO43-:NH4+, reaction time and stirring speed were set 10, 1.2:1:0.9, 30min and 100r/min.
