Establishment of resources recycling and low emission type waste water treatment system by urine diversion

本研究开发了资源循环、低排放的尿液导流型废水处理系统，以降低水耗、能源消耗和水环境污染负荷。开发了水循环引尿厕所、水循环小便池等超级节水厕所。这些新开发的厕所申请了两项专利。然后对日本高速公路服务区用新开发的超级节水厕所替代传统厕所的环境负荷减少情况进行了研究。结果表明，引进新研制的超级节水厕所，大大减少了服务区域的环境负荷。

In this study, the resources recycling and low emission type waste water treatment system by urine diversion was developed to reduce the water consumption, the energy consumption, and the pollution load to the water environment.The super water-saving toilets, such as water-recycling urine-diverting toilets and water-recycling urinals were developed.Two patents were applied regarding these newly developed toilets. Then the environmental load reduction by the replacement of conventional toilets with the newly developed super water-saving toilets at highway service areas in Japan was examined. The results obtained show that the environmental load from the service areas would be reduced greatly by introducing the newly developed super water-saving toilets.
