摘要
以南方某城市典型片区污水管网为例,根据管网拓扑关系制定短期在线监测方案,获取17个监测点为期3个月的有效在线监测数据,对污水管网旱天和雨天的液位和流量数据进行对比分析,定量识别由降雨引起的污水管网入流入渗问题,快速评估降雨入流入渗对污水管网流量变化和运行风险带来的影响,能够为污水管网的修复改造和污水处理的提质增效提供依据,同时为其他城市采取短期在线监测及降雨入流入渗问题诊断的技术方法提供借鉴和参考。
Taking the sewage network of a typical urban district in South China as an instance,this study formulated a short-term online monitoring scheme according to the topological relations of the drainage network.Based on valid online monitoring data of 17 monitoring sites during 1~3 months,a comparison was made between the level and flow-rate data during dry weather and wet weather,in order to identify the problem of rain derived inflow and infiltration(RDII)quantitively.Through rapid assessment of the influence brought to the flow-rate variation and operational risks of drainage network caused by RDII,the analysis was intended to provide basis for the renovation of the sewage pipelines and the quality and effectiveness improvement of wastewater treatment.In the meantime,the methodology of this study will provide other cities with references under similar circumstances.
