Description

Technical Field

[0001] The present invention relates to the technical field of water quality and hydrological feedback mechanisms, and in particular to a method for establishing a water quality and hydrological feedback mechanism. Background Art

[0002] Hydrology refers to various phenomena such as the changes and movements of water in nature. Hydrology now generally refers to a discipline that studies the temporal and spatial distribution and changing laws of water in nature.

[0003] Water quality is the abbreviation of water quality. It indicates the physical (such as color, turbidity, odor, etc.), chemical (inorganic and organic content) and biological (bacteria, microorganisms, plankton, benthic organisms) characteristics of water and its composition.

[0004] As point sources are effectively controlled, urban and rural non-point source pollution is becoming the main contradiction restricting the continuous improvement of the water environment. In many cases, the regulation of pollutant concentrations can no longer meet the needs of management, and total amount monitoring is needed. However, the current unmanned hydrological telemetry stations and water quality telemetry stations are often two independent monitoring units. The two cannot monitor at the same frequency, which makes monitoring meaningless from the perspective of pollution control.

[0005] In addition, existing technologies cannot adjust the monitoring frequency according to the hydrological and water quality monitoring results, so as to accurately obtain the amount of pollutants. Summary of the invention
