Description

Technical Field

[0001] The invention relates to the technical field of water pollution detection mechanisms, and in particular to a detection mechanism used for a water pollution source tracing instrument. Background Art

[0002] The water pollution source tracer is an instrument used to detect and track the source of water pollution. It can identify the pollutants in the water and locate the source of pollution by analyzing water samples. This instrument is usually used in water quality monitoring, environmental protection and water resource management. The advantage of the water pollution source tracer is that it can quickly and accurately find the source of pollution, helping environmental protection departments to take timely treatment measures to protect water resources and the ecological environment.

[0003] As disclosed in the application number 202211237026.9, a multi-dimensional water pollution source tracing method and device are used to cluster the collected fluorescent fingerprints of the water body to be traced with the fingerprints in the typical fluorescent fingerprint library in a preset multi-dimensional fluorescent fingerprint database to obtain a cluster analysis result. If there is no suspected pollution source in the cluster analysis result, the best pollution source determination strategy is matched according to the number of fluorescence peaks and the fluorescence peak emission wavelength in the fluorescent fingerprint of the water body to be traced, and then the suspected pollution source of the water body to be traced is determined.

[0004] However, some existing water pollution source tracing instruments are usually not equipped with a self-cleaning function during actual use.
