| 中文摘要: |
| 源分离尿液中含有大量的氮、磷、钾等营养物质，具有资源性和污染性的双重特征。本文阐述了源分离尿液的特征，归纳了源分离尿液营养物质的回收以及尿液还田对农作物生长的影响，明确了现阶段人尿在农业利用上对土壤理化、药物积累等方面产生的主要问题，最后对源分离尿液替代化肥农业利用的前景进行了展望，指出源分离尿液在农业利用中的潜力，为人尿用作液体肥料科学还田提供了指导和借鉴。 |
| 英文摘要: |
| Source-separated urine contains a large amount of nutrients,such as nitrogen,phosphorus,and potassium,which can be both resources and pollutants.This article describes the characteristics of the source-separated urine,summarizes the technology for nutrient recovery from the source-separated urine,summarizes the effects of urine on crop growth,and clarifies the main effects of utilization of human urine on soil physicochemical characteristics and drug accumulation.Finally,the prospects for the agricultural utilization of sourceseparated urine as a substitute for chemical fertilizers are identified,which would provide a research direction for the return of human urine as liquid fertilizer. |
