摘要
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-revenue water consumption in a District Metered Area （ DMA）, which is difficult to analyze. The key to accurately assess the non-revenue water consumption is to determine the residential nighttime water consumption （RNWC）. The statistical analysis of RNWC in eight residential subdivisions showed a monthly average of 2.85 - 3.47 L/h per household and an annual average of 3.27 L/h per household. Further studies indicated that the linear correlation between the RN- WC and the residential daily water consumption was prominent, which could be used to calculate the RN- WC in the DMA where intelligent water meters were not installed. Therefore, the leakage control in DMA could be achieved more conveniently.
