缺水型特大城市家庭水能关系分析与改进措施

Analysis and Improvement Measures of Water Energy Relationship of Water Shortage Type Super-urban Families

为了探讨缺水型特大城市居民生活用水与用能的纽带关系及节水与节能的同步性,以590份北京市居民生活用水行为调查问卷为样本,分析了北京市居民家庭生活用水的现状,并对其中的终端用水和用水能耗做了一定的识别分析。结果显示,北京市居民家庭生活人均日用水量为125L/(人·d),家庭人均日用水能耗为5.57kW·h/(人·d);对终端用水和用水能耗影响最大的是洗衣和洗浴行为,通过改善这两种行为的用水和用能情况,每年在节水的同时还能最多节能14.7×10^(10)kW·h,这表明可以实现家庭节水与节能的同步进行;分析了城市生活用水系统中终端用水和用水能耗之间的联系,为水资源的保护和管理提供了决策支持。

In order to study the nexus between the residents living water and energy and analyze the synchronization of water-saving and energy-saving in water shortage type supercity,590 questionnaires of Beijing residents living water behavior were selected as the samples.The current status of Beijing residents living water was analyzed.And then the terminal water consumption and water-related energy was make a certain identification.The results show that the daily average water consumption per capita of Beijing is 125L/（person·d）,and the average daily water-related energy consumption per capita is 5.57kW·h/（person·d）.Washing and bathing are the most terminal influencing factors.When improving the behavior of the individual,it can achieve to save the energy with the maximum of 1.47×10^（11） kW·h every year while the water-saving is well done,which proves that the family synchronization of water-saving and energy-saving can be realized.This paper analyzes the relationship between the end-use water and the energy consumption in the urban domestic water system,which provides a decision support tool for the protection and management of water resources.
