【摘要】：供水管网漏失问题是社会关注的热点问题,目前已有的管网检漏技术都是针对干线管道或支线管网而研发,不适用于终端管网,充分考虑供水终端管网的运行特点后,首次提出了一种定量计算与定性判断相结合,大漏失与微小漏失联合监控,单点可扩网络化,技术可行且经济可行的终端管网止漏失技术,并进行了止漏失仪研制及现场测试,可有效防止自来水漏失,减少因管网漏失造成的直接经济损失,防范漏失引发的各种次生灾害。在供水终端管网在线检漏技术的基础上,结合物联网技术进一步开展供水终端管网水能高效开发利用技术研究、供水终端管网水质在线检测技术研究,以及供水终端管网运行状态在线监控及预警系统开发,进而全面推进供水终端管网智慧化建设。
[Abstract]:The leakage problem of water supply network is a hot issue that the society pays close attention to. At present, the existing leak detection technology of pipe network is developed for the trunk pipeline or branch pipeline network, which is not suitable for the terminal pipe network. After fully considering the operation characteristics of water supply terminal pipe network, a combination of quantitative calculation and qualitative judgment is put forward for the first time, which can be combined with large leakage and small leakage, and can be expanded to network at single point. The leakage prevention technology of terminal pipe network is feasible and economical, and the leakage control instrument is developed and the field test is carried out, which can effectively prevent the leakage of tap water and reduce the direct economic loss caused by the leakage of the pipe network. On the basis of on-line leak detection technology of water supply terminal network, combined with the technology of Internet of things, the technology of water energy efficient development and utilization of water supply terminal pipe network is further studied. The research on water quality on-line detection technology of water supply terminal pipe network, and the development of on-line monitoring and early warning system of water supply terminal pipe network operation state, and then advance the intelligent construction of water supply terminal pipe network in an all-round way.
