基于在线监测的污水管道旱天入流入渗分析
摘要：以我国南方某城市为研究区，基于分层级的布点思路，布设了56个监测点位，采用在线监测技术与人工采样化验相结合的方式，应用物料守恒方法，对污水管道的客水入流量进行了定量分析，划分了入渗等级，识别了优先修复等级，并以管道检测技术对分析结果进行验证。结果显示，由于居民小区内化粪池的影响，小区出水浓度低于实际生活污水浓度；研究区域整体入渗率为69%；入渗最严重的点位入渗率高于97%，应及时开展修复；根据监测得到的排水分区入流入渗分析结果与后期开展的管道检测结果完全一致.

Analysis of sewage pipeline inflow and infiltration based on online monitoring
Abstract: Based on the hierarchical arrangement of points,56 monitoring points were arranged.The method of online monitoring technology combined with manual sampling and testing was adopted,and the method of material conservation was applied to the customers of sewage pipelines.Quantitative analysis of water inflow was carried out,infiltration grades were divided,priority repair grades were identified,and the analysis results were verified by pipeline inspection technology.The results show that due to the influence of septic tanks in the residential quarters,the effluent concentration of the community is lower than the actual concentration of domestic sewage;the overall infiltration rate of the study area is 69%;the infiltration rate of the most serious infiltration point is higher than 97%,and it should be timely carried out repairs;the inflow and inflow analysis results of the drainage districts obtained from the monitoring are completely consistent with the pipeline inspection results carried out later.
