| 中文摘要: |
| 人尿中含有丰富的营养物质,随意排放将不仅带来环境污染,同时还会造成资源的浪费。近几年,源分离人尿的资源化利用在工程领域受到了越来越多的关注。本文综述了人尿的成分和目前以资源化利用为目的的几种主要的人尿处理技术,包括农田利用技术、氮回收技术、磷回收技术、钾回收技术及提取生化药品技术。综述结果清晰表明尿液具有巨大的资源回收利用潜力,用于处理单独收集尿液的技术有很多,但是除了直接还田技术外,其他技术均还停留在实验室研究阶段。尿液资源化利用技术的实际工程推广应用还有待进一步发展研究。 |
| 英文摘要: |
| Human urine is rich in nutrients, and random discharge will not only brings environmental pollution, but also wastes the resources. In recent years, the separate collection and treatment of human urine have received increasing attention in the engineering community. This article summarizes the properties of human urine and focuses on several main human urine treatment technologies for the purpose of resource utilization, including farmland utilization technology, nitrogen recovery technology, phosphorus recovery technology, potassium recovery technology and biochemical drug extraction technology. The review clearly indicates that urine has huge resource recycling value and a wide range of technical options is available to treat separately collected urine effectively, but except for the direct farmland utilization, none of the processes described have so far advanced beyond the laboratory stage. Considerable development work remains to be done to optimize the urine-processing techniques and apply to practical engineering. |
