摘要:

针对源分离尿液富含氮、磷等多种营养元素,且具有较高资源回收潜力的特点,首先概述了源分离尿液的特征,重点总结了源分离尿液的氮、磷回收技术(浓缩脱水技术、吸附技术、化学沉淀技术、生物处理技术、电化学技术),并对各项技术的研究进展进行了阐述;然后分析了源分离尿液在农业生产和同步产电领域的应用价值;最后通过展望源分离尿液的发展趋势,指出未来应进一步提高源分离尿液处理过程中氮、磷资源的回收率并将其应用于实际污水处理,以期为真正实现源分离尿液的资源化、无害化和规模化提供参考。

Abstract:

Source-separated urine contains large amounts of nutrients including nitrogen and phosphorus,which has the high resource recovery potential. In this review,the characteristics of source-separated urine were firstly summarized. The recovery technologies of nitrogen and phosphorus(such as concentration and dehydration technology,adsorption technology,chemical precipitation technology,biological treatment technology and electrochemical technology) were expounded in details, and the research progress of various technologies were described. Then,the application value of source-separated urine in agricultural production and synchronous electricity generation was analyzed. Finally, it was pointed out that the future research should be focused on improving the recovery rate of nitrogen and phosphorus in the process of urine separation and applying it to practical wastewater treatment by outlooking the development trend of source-separated urine. This review provided a reference for the true application for urine harmlessness,recycling,and enlarged scale production.

Key words: source-separated urine, nitrogen and phosphorus recovery, agricultural utilization, synchronous electricity generation, resource utilization
