Embodiment Construction

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] Such as figure 1 As shown, the present invention provides a method for traceability of urban drainage pipe network pollution. It mainly divides the flattened topology into topological layers and abstracts the network graph into blocks to establish a tree-shaped topology, and then analyzes the pollution on the basis of the tree-shaped topology. Traceability analysis. It speci...

Abstract

The invention discloses an urban drainage network pollution tracing method, which comprises the following steps of: establishing a tree topology structure according to data of a GIS (Geographic Information System) platform, and determining a transmission path and nodes of a drainage network; monitoring the water quality condition of each node according to the tree topology structure; and when the water quality condition is abnormal, judging the nodes to be abnormal nodes, and determining pollution source nodes according to the transmission path of the tree topology structure. According to the urban drainage network pollution tracing method provided by the invention, based on the analysis of the topological network structure of the drainage network, the existing topological structure of the drainage network is optimized, and the express delivery and accurate analysis of the drainage network are realized in cooperation with various search algorithms.

Description

technical field [0001] The invention relates to the field of drainage pipe networks, in particular to a method for tracing pollution sources of urban drainage pipe networks. Background technique [0002] With the rapid development of industrial production, the amount of sewage is also increasing day by day. Water pollution has become one of the most important environmental problems at present. Industrial sewage is directly discharged into natural rivers or underground pipelines without treatment, which will cause serious environmental pollution and bring great harm to people's lives. cause great harm. As the regulatory requirements for the environment become more and more stringent, it is an indispensable link to investigate the source of pollution and trace the source of pollutants. Only when the source of pollution is well traced can the source of pollution be cut off in a timely manner to prevent further deterioration of the pollution situation; and the responsibility of...
