摘　　要：人类排泄物中存在大量的资源,采用粪尿源分离便器对粪便与尿液进行收集,并分别采用厌氧消化与正渗透(FO)+反渗透(RO)膜系统对粪便与尿液进行处理和资源化。介绍了这种厕所资源回收系统的设计及实际系统的运行效果。运行结果表明,分离膜系统对尿液中的营养物质(TP、K)截留率可达80%以上,产出的回用水水质优于《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)标准。正渗透技术作为一种较新的膜分离技术,在尿液的浓缩回用中有良好的应用前景。Human excreta contains large amount of resources. In this project, urine diversion toi- let was used in the new kind toilet, after separated collection, feces and urine were respectively treated via anaerobic digest followed by forward osmosis and reverse osmosis （ FO ＋ RO） membrane system. The design parameters of the toilet system were introduced as well as its operational results. The results showed that the rejection of TP and K nutrient from urine was over 80%, and the reclaimed water met The Reuse of Urban Recycling Water--Water Quality Standard for Urban Miscellaneous Water Consumption （GB/T 18920 -2002）. As a new membrane separation technology, FO has a good application prospect in urine concentration and feuse.
