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、发改委等三部委联合发布《城镇污水处理提质增效三年行动方案(2019~2021 年)》,要求各地政府负责落实建立污水管网排查和周期性检测制度,建立和完善基于GIS系统的动态更新机制,逐步建立以 5~10年为一个排查周期的长效机制和费用保障机制,众所周知城市排水管网问题复杂且关键,是影响排水防涝及水环境治理的重要因素。排水管网存在设计不合理、管网错混接、偷排、破损、复杂性、不确定性等因素,使得排水系统功能存在诸多缺陷[1-3]。管网普查存在难度大、数据杂乱、耗费资金高等因素[4],且会较大程度影响现状排水系统运行,在一定程度上制约了对排水系统运行及维护。排水管网智慧监测通过感知层设备采集数据,综合分析后诊断排水运行工况,有助于完善排水系统,对排水信息化建设管理具有重要意义。
当下对于城市管网检测的主要方法是声呐、潜望镜和井下机器人(CCTV)等,可以较直观的发现管网结构性缺陷,但是也存在效率较低、施工条件有要求和成本较高的缺点[5-7]。而选择排水管网数字化监测诊断技术,综合分析评估片区管网旱季和雨季入流入渗的状况,快速诊断出片区管网“健康”问题,是管网监测和修复的一种重要支撑技术。本研究以某地区排水滚网为例,系统阐述该方法的应用效果,以供其他地区借鉴。
