摘要
过量的外水通过入流入渗进入市政污水管网会导致管道内流量过高、污水冒溢、污水厂污染物进厂浓度过低等问题,对外水定位定量检测是污水管网正常运行的先决条件,本文介绍了国内外外水入流入渗漏点定位技术、外水量评估方法和相关应用,并总结对比了各技术的适用场景和使用限制.结果表明,各种检测技术往往需要结合使用,并且需要明确检测的目的,选择合适的技术组合.研究可为外水排查技术的科学应用和创新提供参考.
Abstract
Excessive infiltration and inflow of external water into the municipal sewage pipeline network can lead to problems such as excessive flow inside the pipes,sewage overflow,and low pollutant concentration at wastewater treatment plants. Locating and quantitatively detecting external water inflow is a prerequisite for the normal operation of sewage pipeline networks. This paper introduced techniques for locating infiltration and inflow points of external water domestically and internationally,methods for assessing the volume of external water,and their respective applications. It also summarized and compared the applicable scenarios and limitations of each technique. The results indicated that various detection technologies usually need to be used in combination,and it's essential to clarify the purpose of detection and select an appropriate combination of techniques. This research can serve as a reference for the scientific application and innovation of techniques for identifying external water infiltration.
