水质分析在城镇污水管网重点排查范围划定中的应用

The Application of Water Quality Analysis in the Delineation of Key Investigation Scope of Urban Sewage Pipe Network

文章制订了一套基于水质诊断分析的城镇污水管网重点排查范围划定方法,依据水质分析判定问题等级、排查优先级,可为管网精细排查和整治提供依据。该方法效率高、适用性和经济性强,对城镇污水系统提质增效具有重要意义。文章将该方法应用于南方某城镇,在研究区域内58.27 km长的污水管道上布设100组水质检测点,定量分析后划定了重点排查管段、片区,确定了排查优先级,提出了管网精细排查和整治建议,旨在为我国污水管网排查诊断工作提供借鉴。

A set of methods for delineating key investigation scope of urban sewage pipe network is formulated based on water quality diagnosis and analysis.Determining the problem level and investigation priority according to water quality analysis can provide a basis for fine investigation and remediation of pipe network.The method has high efficiency and strong applicability and economy and is of great significance to improve the quality and efficiency of urban sewage system.In this paper,the method was applied to a town in the south of China,and 100 groups of water quality detection points were set up on the 58.27-km-long sewage pipe in the study area.After quantitative analysis,the key investigation sections and areas were delineated,and the investigation priority was determined.The suggestions for fine investigation and remediation of pipe network were put forward,aiming to provide reference for the investigation and diagnosis of sewage pipe network in China.
