On-line biological safety early warning and monitoring method for water quality

Abstract

The invention discloses an on-line biological safety early warning and monitoring method for the water quality. By means of the method, continuous real-time on-line water comprehensive toxicity early warning according with a toxicology mechanism can be achieved. The method comprises the following steps that the absolute motion behavior changing process of a tested aquatic organism in a to-be-monitored water body is monitored by a biological behavior sensor on line in real time and compared with the motion behavior changing process of a same-variety tested aquatic organism in a pollution-free standard water body, normal motion behavior changes are filtered out to obtain the relative motion behavior changing process of the tested aquatic organism in the to-be-monitored water body, and qualitative and / or quantitative evaluation is conducted on the biological safety of the to-be-monitored water body accordingly. The method is particularly suitable for biological safety early warning on sudden pollution accidents of natural water bodies or drinking water sources and has the advantages that early warning is more precise, pollutant concentration early warning can be conducted on the monitored water body, the method is simple, and secondary pollution cannot be caused to the environment of the to-be-monitored water body.

Description

technical field [0001] The invention belongs to the technical field of water environment monitoring, and relates to an online water quality biosafety early warning monitoring method, in particular to an online water quality biosafety early warning monitoring method based on pattern recognition and monitoring of aquatic biological behavior changes based on electrical signal technology, video image technology and the like. Background technique [0002] Accidental discharge of pollution sources, leakage of industrial chemicals transportation, man-made release of toxic substances, toxic algal blooms and algal toxins and other sudden water pollution accidents have seriously affected social development, stability and people's safety and health. Therefore, continuous and effective early warning of water quality is the goal and direction of the development of water quality monitoring. my country currently has 106 surface water quality standards, but the aquatic biological standards ...

AI Technical Summary

Problems solved by technology

When the COD, pH, and conductivity of the source water change significantly, the physical and chemical indicators indicate that a pollution accident may have occurred, but it is not enough to judge the nature of the pollution accident

Moreover, online water quality physical and chemical analysis products have problems such as weak adaptability in harsh environments, poor long-term stability, large reagent consumption, secondary pollution, high device failure rate, heavy maintenance workload, high operating costs, and poor platform versatility.
