对高校用水的研究多直接分析历年宏观统计数据,得出的结果难以真实说明生活用水过程.现从微观个体实验的角度出发,结合水平衡测试,对北京师范大学学生用水过程进行详细研究,得出北京师范大学学生用水定额为100L/(人·d),用水定额先进,节水潜力有限;夏季人均日用水量比冬季约多28%;女生人均日用水量比男生多20%;对比其他研究成果可知,学生洗浴用水量过大,建议通过改进淋浴喷头的出水量,使学生次洗澡用水量降为国家规定的100 L,则可年节约水量1.5万m~3.
對高校用水的研究多直接分析歷年宏觀統計數據,得齣的結果難以真實說明生活用水過程.現從微觀箇體實驗的角度齣髮,結閤水平衡測試,對北京師範大學學生用水過程進行詳細研究,得齣北京師範大學學生用水定額為100L/(人·d),用水定額先進,節水潛力有限;夏季人均日用水量比鼕季約多28%;女生人均日用水量比男生多20%;對比其他研究成果可知,學生洗浴用水量過大,建議通過改進淋浴噴頭的齣水量,使學生次洗澡用水量降為國傢規定的100 L,則可年節約水量1.5萬m~3.

The result of studies on the direct analysis of water consumption in the uruversities over the macroeconomic statistics can hardly explain the real process.In this paper, the individual expetiments, combined with water balance tests are used to study the students' water consumption,and the conclusion is that the norm of water intake for the students in Beijing Normal University is 100 L/day per capita which showed that the water conservation potential is Limited.The norm of water intake in summer is 28% more than in winter and girls' is 20% more than boys.Compared to other results we can see the water consumption on bathing is excessive.By improving the shower volume to 100 L,15,000 m~3 water can be saved each year.
