【摘要】：供水管網(wǎng)漏失問題是社會關(guān)注的熱點問題,目前已有的管網(wǎng)檢漏技術(shù)都是針對干線管道或支線管網(wǎng)而研發(fā),不適用于終端管網(wǎng),充分考慮供水終端管網(wǎng)的運行特點后,首次提出了一種定量計算與定性判斷相結(jié)合,大漏失與微小漏失聯(lián)合監(jiān)控,單點可擴網(wǎng)絡(luò)化,技術(shù)可行且經(jīng)濟可行的終端管網(wǎng)止漏失技術(shù),并進行了止漏失儀研制及現(xiàn)場測試,可有效防止自來水漏失,減少因管網(wǎng)漏失造成的直接經(jīng)濟損失,防范漏失引發(fā)的各種次生災(zāi)害。在供水終端管網(wǎng)在線檢漏技術(shù)的基礎(chǔ)上,結(jié)合物聯(lián)網(wǎng)技術(shù)進一步開展供水終端管網(wǎng)水能高效開發(fā)利用技術(shù)研究、供水終端管網(wǎng)水質(zhì)在線檢測技術(shù)研究,以及供水終端管網(wǎng)運行狀態(tài)在線監(jiān)控及預(yù)警系統(tǒng)開發(fā),進而全面推進供水終端管網(wǎng)智慧化建設(shè)。
[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.
