DMA小区内无收益水量类型较多,分析困难,确定居民夜间合法用水量是对其类型准确分离的关键。因此,采用统计学方法分析了广州8个居民小区夜间合法用水量,其样本总体月平均值介于2.85~3.47 L/(户·h)之间,年平均值为3.27 L/(户·h)。夜间合法用水量Y与日用水量X之间存在较好的线性相关性,据此可计算未装智能远传水表的DMA小区居民夜间合法用水量,从而为小区漏损控制奠定基础。
There are many types of non-profit water in DMA plot, and it is difficult to analyze. Determining the legal water consumption of residents at night is the key to the accurate separation of their types. Therefore, the statistic method was used to analyze the nighttime legal water consumption of 8 residential communities in Guangzhou. The monthly average of samples was between 2.85 ~ 3.47 L / (household · h) with an annual average of 3.27 L / (h · h ). There is a good linear correlation between the nighttime legal water consumption Y and the daily water consumption X. Based on this, the legal night water consumption of residents in DMA community without intelligent remote water meter can be calculated, which lays the foundation for the control of the leakage of residential district.
