Abstract: The central conference reiterated many times to speed up the construction of sewage pipe network and other facilities, in order to achieve the goal of full coverage of sewage pipe network, full collection, full treatment to lay a solid foundation. According to the sewage pipe network hierarchy monitoring unit, and through the ZhuGanGuan submain - branch pipe, and river crossing, and other important node set water quantity and water quality monitoring stations, and combined with river and typical field of water quality testing data, the research scope of drainage pipe network for water quality of the relationship between, run the risk of the monitoring, pipeline flow ability, such as severe drought inflow infiltration situation analysis, To distinguish the network operation risk level, health assessment of sewage pipe network system and its influence to the whole area, through to clarify the key problems and weight classification, formulate follow-up inspection, repair work priority, in order to solve the problem as the guide, highlight focus main forces to strengthen rectification implementation, so that the sewage treatment system, mass transfer efficiency project immediate Reduce the cost of inspection and rectification. Key words: urban sewage treatment plant; Digital monitoring; Pipe network transformation; Digital diagnosis |
2019年住建部、發(fā)改委等三部委聯(lián)合發(fā)布《城鎮(zhèn)污水處理提質增效三年行動方案(2019~2021 年)》,要求各地政府負責落實建立污水管網排查和周期性檢測制度,建立和完善基于GIS系統(tǒng)的動態(tài)更新機制,逐步建立以 5~10年為一個排查周期的長效機制和費用保障機制,眾所周知城市排水管網問題復雜且關鍵,是影響排水防澇及水環(huán)境治理的重要因素。排水管網存在設計不合理、管網錯混接、偷排、破損、復雜性、不確定性等因素,使得排水系統(tǒng)功能存在諸多缺陷[1-3]。管網普查存在難度大、數據雜亂、耗費資金高等因素[4],且會較大程度影響現(xiàn)狀排水系統(tǒng)運行,在一定程度上制約了對排水系統(tǒng)運行及維護。排水管網智慧監(jiān)測通過感知層設備采集數據,綜合分析后診斷排水運行工況,有助于完善排水系統(tǒng),對排水信息化建設管理具有重要意義。
當下對于城市管網檢測的主要方法是聲吶、潛望鏡和井下機器人(CCTV)等,可以較直觀的發(fā)現(xiàn)管網結構性缺陷,但是也存在效率較低、施工條件有要求和成本較高的缺點[5-7]。而選擇排水管網數字化監(jiān)測診斷技術,綜合分析評估片區(qū)管網旱季和雨季入流入滲的狀況,快速診斷出片區(qū)管網“健康”問題,是管網監(jiān)測和修復的一種重要支撐技術。本研究以某地區(qū)排水滾網為例,系統(tǒng)闡述該方法的應用效果,以供其他地區(qū)借鑒。
