摘要
以某片区污水管关键节点的水质水量为分析对象,开展该片区污水管网的缺陷诊断。通过建立片区污水管网概化图,制定基于关键节点的水质水量监测方案,采用层层递进的方式,根据第1次主干管道上关键节点的水质水量分析结果,选取COD为重点检测指标,划定第2次监测的重点管网区段和范围,并基于第2次的COD浓度划定重点排查的支管区段和范围,最终确定造成该段污水管网缺陷问题的原因和位置,为片区污水管网的修复治理工程提供有效支撑。
Taking the water quality and flow rate data from key nodes in a sewage pipe network as the analysis object,this study conducted defect diagnosis for the regional sewage pipeline system.By developing a simplified schematic of the sewage network,a monitoring plan for water quality and quantity at key nodes was designed.Using a step-by-step approach,the initial analysis of water quality and flow data from key nodes in the main pipelines identified COD as a critical detection indicator.Based on this finding,the second monitering focused on specific high-priority pipe sections.Further analysis of COD concentrations from the second round of testing helped narrow down the key inspection areas to specific branch pipe segments.Ultimately,the causes and locations of defects in the sewage pipe network were determined,providing effective support for the subsequent repair and rehabilitation of the regional sewage system.
