Abstract

Abstract:

Effect of automatic urine separation technology on collection of high phosphorus concentration urine and phosphorus recovery was investigated. The influence of urine purity on phosphorus recovery in a reactor was studied. The results indicated that the extending delay time resulted in decrease of urine purity whereas raising urinary amount resulted in increase of urine purity. Rate of phosphorus recovery in urine exceeded 96% under the condition of urine purity higher than 70%. The proposed urine automatic collection from urinal based on source separation of urine from flushing water effectively recovers very pure urine to meet the demand of phosphorus recovery through struvite as a fertilizer.

Key words: phosphorus recovery, source separation of urine from flushing water, urine automatically collected from urinal
