高校生活节水技术与措施改进研究——以北京师范大学为例

Study on the Improvement of Domestic Water-saving Technologies and Measures in Universities ——A Case Study in Beijing Normal University

高校是用水大户,研究与改进生活节水技术与措施意义重大。以北京师范大学为例,通过分析该高校的生活用水情况、节水措施,指出节水工作中存在中水处理能力不足、学生使用自来水浪费、洗澡用水量过大、冲厕用水浪费、用水器具常损坏导致漏水损失的问题。针对上述问题,提出了增加中水处理规模、基于定额管理的学生宿舍自来水用水控制、基于阶梯式水价的学生洗澡用水控制、冲厕水量控制、供水系统故障举报奖励机制这五项节水技术与措施。上述技术措施是在现有节水技术措施上的改进和完善,具有良好的可行性。在采取上述措施后,学校每年可节水约22.8万m3,节水效益明显。

Universities use a lot of water, and thus it has a great significance to research and improve the domestic water-saving technologies and measures in universities. The domestic water uses and water-saving measures are studied in Beijing Normal University, which proposes several problems in the water conservation, such as the lack of capacity in the treatment of the reclaimed water, the waste of tap water, the excessive water for bath, the waste of the flushing water,and the water loss caused by the damages of the water appliances. Five water-saving technologies and measures are proposed, including the increasing of the treatment of the reclaimed water, the tap water control in the student dormitory based on the quota management, the bath water control based on the laddered water price, the flushing water control,and the reward mechanism for reporting the malfunction of the water supply system. The above tech- nologies and measures are proposed based on the improvement of the existing water-saving technologies and measures and have a good feasibility. There are a total of 228 thousand cubic meter of water which can be saved every year if these measures are performed for the university,and thus these measures are beneficial for water conservation.
