摘要
节水型高校建设是节水型城市建设的重要组成部分,高校节水对进一步推动社会节水具有重要意义。文中以上海市某高校为例,围绕高校普遍采取的4项主要节水措施(节水型器具改造、管网漏损控制、中水回用、雨水回用),分别探讨其节水效益、经济效益和碳减排效益。结果表明,直接节约水量措施的碳减排效益远远大于回用水量措施;节水型器具改造工程节水、经济、碳减排效益均较好;管网漏损控制节水及碳减排效益处于中间水平,但不同高校管网节水潜力差异较大;中水回用节水效益最佳,但碳减排效益最差;雨水回用节水及经济效益处于中间水平,碳减排效益较差。因此,应优先开展节水型器具改造,加强精细化管理的同时,严格落实管网漏损控制,结合实际情况适时开展中水回用或雨水回用。
The construction of water-saving universities is an important part of the construction of water-saving cities. Water saving in universities is of great significance to further social water saving. Taking a university in Shanghai as an example, this paper discussed the water-saving benefits, economic benefits and carbon emission reduction benefits of four major water-saving measures(water-saving appliance renovation, pipe network leakage control, reclaimed water reuse and rainwater reuse). The results showed that the carbon emission reduction benefits of direct water saving measures were far greater than those of water reuse measures;the watersaving appliance renovation had good water-saving, economic and carbon emission reduction benefits;the benefits of water-saving and carbon emission reduction of pipe network leakage control were in the middle level, but the water-saving potential of pipe network was different in universities;the water-saving benefit of reclaimed water reuse was the best, but the carbon emission reduction benefit was the worst;the water-saving and economic benefits of rainwater reuse were in the middle level, and the carbon emission reduction benefits were poor. Therefore, priority should be given to the water-saving appliances renovation, and the leakage control of pipe network should be strictly implemented while strengthening the fine management. The reclaimed water or rainwater should be recycled in a timely manner according to the actual situation.
