庵埠水厂取水计量率定物理试验研究

Physical Model Test of Water Intake Metering Calibration for Anbu Waterworks

随着最严格水资源管理制度的实施及深入,取水有效计量成为申请取水许可的基础性条件之一,越来越受到取水户重视。汕头庵埠水厂为已建老厂,取水管线未安装计量设备,且取水管线布设上未预留理想计量安装位置,致使新增计量的计量精度受到一定的影响。为此,通过对水厂吸水井孔口出流物理模型试验研究,并结合现场水位计数据,推算水厂吸水井长系列过流流量,并与同步监测的流量计计量值进行比较,给定流量校正系数。研究方法可为类似取水户的取水计量建设提供参考。

With the implementation and deepening of the most stringent water resources management system,the effective measurement of water intake has become one of the basic conditions to apply for water licensing,and more and more attention has been paid to water users.Shantou Anbu waterworks is an old factory,and its water intake pipeline didn t install metering equipment,and meanwhile,the pipeline didn t have ideal metering installation position,what would affect the measuring accuracy in new measurement.Therefore,through the physical model test and the local water level data,the long flow series of the suction well in the waterworks is calculated,and the flow correction coefficient is obtained by comparing the synchronous monitoring flow.The method can provide reference for the construction of water intake measurement which is similar to the pipeline layout of Anbu waterworks.
