摘要
人尿中含有丰富的营养物质,随意排放不仅带来环境污染,而且会造成资源的浪费。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。本文综述了以资源化利用为目的的人尿处理技术,包括农田利用技术、氮回收技术、磷回收技术、钾回收技术及生化药品提取技术,旨在为我国人尿高效资源化利用寻求可推广可应用的技术方法。综述结果表明尿液具有巨大的资源回收利用潜力,用于处理源分离尿液的技术有很多,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应用还有待进一步研究推广。
Human urine is rich in nutrients, and random discharge not only results in environmental pollution, but also wastes these nutrient 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 important treatment technologies for the purpose of resource reclamation from human urine, including technologies for farmland utilization, nitrogen, phosphorous and potassium recovery and biochemical drug extraction. This 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. However, with the exception of direct farmland utilization, none of the processes described have advanced beyond the laboratory stage. Considerable development remains to be undertaken to optimize urine-processing techniques and apply them in a practical engineering setting.
