Embodiment 1

[0047] Embodiment 1, using the method provided by the present invention to carry out online biosafety early warning to source water polluted by organic pollutants

[0048] The schematic diagram of the monitoring and analysis process of aquatic organism behavior data in the method of the present invention is as follows figure 2 shown.

[0049] Sexually mature individual medaka fish aged 3-4 months were selected as the tested aquatic organisms, and their biological behavior changes were monitored. An 8-channel double-layer biological behavior sensor (jointly developed by the Eco-Environmental Research Center of the Chinese Academy of Sciences and Wuxi Zhongke Water Quality Environmental Technology Co., Ltd., model BDTS-02) is used to extract aquatic biological behavior signals through electrical signals and high-definition cameras. Intensity (comprehensive biological behavior: the synthesis of various modes of movement such as swimming, fin swinging, and breathing movement of ...

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 ...
