摘　　要：目前污水处理量的逐渐增长与进水浓度的持续走低已成为城市污水管网普遍存在的问题,究其根本主要体现在污水管网的雨天入流入渗及旱天入流入渗。其中雨天的入流分析多借助在线流量监测技术,通过管道雨天过流量与旱天的对比即可迅速定位,而旱天入渗往往比较隐蔽无法单纯依靠流量数据进行准确查找。地毯式的CCTV、QV管网诊断方式,不仅无法对管网入流入渗量进行量化,而且耗资巨大且无法实现。通过对研究区域管网末端水厂数据的本底分析,发现区域存在的入流入渗现状及指标特性,借助在线监测点位的布设,获取有效监测数据,确定监测点位处的入渗量,进而为工程的下一步开展提供方向。The gradual increase of sewage treatment volume and the continuous decrease of influent concentration have become a common problem in urban sewage pipe network, which is mainly reflected in the inflow of sewage pipe network in rainy weather and dry weather infiltration. At present, inflow analysis in rainy days mostly uses online flow monitoring technology, and the rainy weather flow through the pipeline can be quickly located by comparing with the dry weather. However, the infiltration of dry weather is often more hidden and cannot be accurately searched solely by flow data. The carpet-like CCTV and QV pipeline network diagnosis methods not only cannot quantify the inflow and infiltration volume of the pipeline network, but also cost a lot of money and cannot be realized. Based on the background analysis of the data of the water plant at the end of the pipe network, this paper finds the current status and index characteristics of the infiltration in the area. With the help of the online monitoring point layout, effective monitoring data can be obtained to determine the infiltration at the deployed monitoring point, which provides the direction for the next step of the project.
