Abstract

Nitrification of human urine performed for its stabilization, and culture of Spirulina platensis in the nitrified human urine were investigated for nutrient recovery. With daily adjusting to pH 8 and keeping high dissolved oxygen concentration, mean 95.0% of NH4-N in human urine can be finally stabilized and oxidized to NO3-N. Furthermore, this nitrified human urine seems to be an ideal culture medium for S. platensis. Without pH adjustment, only about 50.0% NH4-N could be converted, i.e. NH4NO3 would be formed. Under low dissolved oxygen concentration, mainly short nitrification (from NH4-N to NO2-N) occurred.
