【摘要】 天津某高校开展的学生宿舍冲厕节水器具改造项目取得了显著的节水效果,项目采用纳米材料免冲水小便器替换男生宿舍传统红外感应小便器,其运用特殊抑菌涂层,有效抑味抗菌、无需冲水。同时,在蹲厕器上加装节水增压阀,通过冲水管内的水气混合装置,革新冲水结构,将水流汇聚为高速扇形喷射流,大幅提升冲刷效率。每年合计节水3.33万吨,节约水费18.29万元。本文详细阐述了项目实施的背景、创新方案、突出成效及推广的可行性,总结出具有实用性和推广性的冲厕节水器具改造策略,为其他高校进行相关节水改造项目、打造节水型校园,乃至全社会推进节水型社会建设提供了经验借鉴,具有重要的理论与实践价值。更多还原

【Abstract】 The water-saving equipment renovation project for flushing toilets in student dormitories of a university in Tianjin has achieved significant water-saving effects. In this project, water-free urinals are used to replace the traditional infrared sensing urinals. Its special antibacterial coating can effectively suppress odor and bacteria, thus eliminating the need for flushing. And pressure flushing valves have been installed in squat toilets,which innovatively reforms the flushing structure through the water-air mixing device inside the flushing pipe, converges the water flow into a high-speed fan-shaped jet flow, and significantly improves the flushing efficiency. As a result,33300 tons of water are saved annually, and 182900 yuan in water bills are saved annually. The implementation background, renovation plan, effectiveness, and feasibility of promotion of the project are elaborated in detail in this article.The strategy for the renovation project of water-saving flushing equipment has been summarized,which is practical and promotable for other universities to carry out relevant water-saving renovations and create water-saving campuses.The practical exploration and effectiveness analysis in this article have important theoretical and practical value.更多还原
