Pipeline water quality risk evaluation method based on water supply network dynamic model

Abstract

The present invention discloses a pipeline water quality risk evaluation method based on a water supply network dynamic model. Establishing a water supply network dynamic waterpower and water quality model and performing accurate checking of the water supply network dynamic waterpower and water quality model through determination of the classification type and the evaluation indexes of the pipeline water quality risk; determining the weight of each evaluation index through adoption of the analytic hierarchy process; and dividing the grading standard of each evaluation index parameters based on the state data samples of the pipe network dynamic model, determining the degree of membership of each evaluation index, performing the fuzzy comprehensive evaluation, and determining the grade of the water quality risk of each pipeline in the pipe network. Though the steps mentioned above, all the pipelines of the whole water supply network are subjected to water quality risk evaluation, and the comparison and the ordering are performed according to the evaluation result to determine risk degree ordering of water quality changing and provide decision support for the management and maintenance of the pipe network; and moreover, the pipeline water quality risk evaluation method based on the water supply network dynamic model overcomes the defects that other evaluation methods are simple in index and do not take incomprehensive consideration, and the evaluation result is more reliable to ensure the accuracy and the life cycle of the evaluation.

Description

technical field [0001] The invention relates to the field of water supply pipe network operation management, and more specifically, relates to a pipeline water quality risk assessment method based on a dynamic model of the water supply pipe network. Background technique [0002] As an important part of the urban water supply system, the water supply pipe network system is an important link that is directly related to the water safety of users. Therefore, ensuring the water quality safety of the water supply network is one of the major issues that domestic and foreign water supply companies have been paying attention to and facing. However, due to the large internal surface area of ​​the pipe wall, the water supply pipe network is a large and complex system for drinking water quality, similar to a huge tubular biochemical reactor. A lot of research data have shown that the quality of drinking water is gradually decreasing from the factory to the user. The main reason is that...
