摘　　要：通过对西安市主城区的15个住宅小区二次供水流量的监测以及高层住宅小区的高区供水流量和四家住户用水行为的深入分析,探讨了住宅小区用水特征及其对二次供水系统良性运行的影响。研究发现,不同小区的用水量与总户数紧密相关,且居民用水量受住户人数、生活习惯和节假日的影响显著,受气温影响较小;住户的人均平均日用水量普遍低于《建筑给水排水设计标准》(GB 50015-2019)中平均日用水定额的下限。淋浴器、马桶、厨房洗涤盆和阳台洗涤盆的用水量占比较高,其中淋浴器为主要用水器具。研究结果为二次供水系统的优化设计和节能改造提供了科学依据,并对现行设计标准提出了修订建议,以促进二次供水行业的可持续发展。Based on the monitoring of secondary water supply flow of 15 residential districts,the water supply flow of high-rise residential districts and the water use behavior of four households in the main urban area of Xi'an city,the paper discusses the water use characteristics of residential communities and its influence on the benign operation of secondary water supply system.The results show that the water consumption of different communities is closely related to the total number of households,and the water consumption of residents is significantly affected by the number of households,living habits and holidays,but is less affected by temperature.The average daily water consumption per capita of households is generally lower than the lower limit of the average daily water consumption quota in the Design standard for building water supply and drainage(GB 50015-2019).The water consumption of shower,toilet,kitchen wash basin and balcony wash basin is relatively high,of which the shower is the main water appliance.The research results provide a scientific basis for the optimal design and energy-saving transformation of the secondary water supply system,and put forward some suggestions for revising the current design standards to promote the sustainable development of the secondary water supply industry.
