摘　　要：在研发源头尿水自动分离技术的基础上，集成了尿液磷高效回收技术．评价了延迟时间和如厕尿量对尿水分离影响，以及尿纯度对尿液磷回收影响．结果表明，随延迟时间增长，收集的尿纯度下降；随如厕尿量增加，尿纯度增加．在70％～100％尿纯度下，尿液磷回收率大于96％．可见，研发的基于尿水分离小便器的尿液磷回收技术，在回收尿液磷领域具有广阔的应用前景．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.
