Global toughness efficient evaluation method for water supply pipe network water quality monitoring system

Abstract

The invention discloses a global toughness efficient evaluation method for a water supply pipe network water quality monitoring system. The water quality monitoring system global toughness efficient evaluation index based on water quality monitoring point failure is provided for the first time, and is used for evaluating the pollutant invasion resistance of the water quality monitoring system under the failure working conditions of different numbers of monitoring points. Meanwhile, the invention provides a pollution event database construction method based on data driving. In the optimizationmodel solving process, the target function is calculated by directly reading the related data in the database, time spent on repeatedly operating hydraulic power and water quality simulation is avoided, compared with a traditional method, the solving efficiency of the optimization model is improved by ten thousand times or above, and the method has obvious advantages particularly when the problemof a large complex actual water supply pipe network is solved. According to the monitoring point importance degree quantification method, the monitoring points with high priorities are maintained, sothat the water quality safety risk of the water supply system can be reduced, and the water supply safety is guaranteed.

Description

technical field [0001] The invention relates to the fields of municipal engineering and urban water supply pipe networks, in particular to an efficient global toughness evaluation method for water quality monitoring systems of water supply pipe networks. Background technique [0002] The water supply network undertakes the task of transporting the drinking water treated by the water plant to the residential users, so it is closely related to the people's life and health. However, due to the complexity of the topological structure of the pipe network itself and its wide coverage, the water supply pipe network is extremely vulnerable to the invasion of external pollutants. For example, in May 2016, the misconnection of reclaimed water pipes in Beijing caused a large amount of sewage to enter the water supply pipe network, which was discovered after a long period of time, seriously endangering the lives and health of residents. In recent years, by optimizing and arranging a ce...
