Exploration of Identification and Detection Methods of Water Outside Pipe

Network in Wastewater Treatment Quality and Efficiency Improvement

【Abstract】： In order to accurately find out the location of water infiltration points in the sewage network， different water quality detection methods are used for the detection of non-external water infiltration points， based on the actual case of the integrated design and construction project of a sewage collection system drainage pipe network in Nanjing， this paper analyzes the source of external water in the sewage pipe network， and provides a quick method for the investigation， detection and identification of water infiltration points in the sewage pipe.
