Pollution source tracking method based on river network online monitoring

Abstract

The invention discloses a pollution source tracking method based on river network online monitoring. The method comprises the following steps: S1, setting monitoring nodes and a data processing center; S2, the monitoring nodes automatically collecting water samples from all nodes of the river through online sampling equipment, and conducting water quality analysis through a water quality detector;S3, signal transceiving equipment sending analysis data of the water quality detector to a data processing center; S4, identifying and classifying the pollution elements in the river by the calculation processing module; s5, the calculation processing module obtaining the pollution index of each node; s6, marking space-time distribution characteristics of the pollution indexes by a calculation processing module; and S7, marking rivers with remarkable pollution characteristics according to the space-time distribution characteristics of the pollution indexes, tracking complete pollution flow traces according to the corresponding main flow, branch flow and catchment nodes, and tracking the range of a pollution source according to the flow traces and the directional monitoring nodes.

Description

technical field [0001] The invention specifically relates to a method for tracking pollution sources based on online monitoring of river networks. Background technique [0002] In today's increasingly severe environmental problems, river sewage treatment is still facing great challenges. In order to avoid exceeding the discharge quota, some industrial enterprises secretly buried underground pipes, and discharged pollutants into rivers through complex hidden pipes, resulting in river pollution, massive death of aquatic organisms, and pollution of the environment along the river. In the existing technology, the sewage discharge of hidden pipes often relies on reporting and manual investigation, which not only makes it difficult to track the location of the pollution source, but also easily evolves into a gust of wind-style rectification without long-term monitoring and governance. Contents of the invention [0003] The purpose of the present invention is in order to solve a...
