The more representative patents are: the patent application number is 200820226398.0, and the Chinese invention patent named "Water Quality Sudden Biological Behavior Indicator Monitoring System" discloses that by monitoring the changes in biological behavior indicators, real-time analysis of water quality conditions, to achieve sudden pollution of water bodies On-line biological monitoring of accidents; the patent application number is 201310425848.4, and the Chinese invention patent titled "Early Warning Device and Method for Identifying Sudden Water Pollution Based on Biological Population Blocks" realizes quantitative and simultaneous early warning of various water pollution severity levels, However, the early warning results were not checked, the influence of biological inherent activities on the results was not stripped, and the differences in fish behavior were not quantified, which is prone to false positives
There are still some deficiencies in the existing online biological early warning technology for sudden water pollution, mainly in 1) it can only use the behavior analysis of aquatic organisms to obtain a single-level qualitative identification, that is, it can only judge whether water pollution occurs, but cannot accurately It is difficult to provide quantitative information support for emergency response to sudden water pollution by judging the degree of pollution; Interfering effects caused by changes in the behavior of the organism itself

Abstract

The invention discloses a water pollution monitoring and early warning device based on fish behavior, and also discloses an early warning method of the water pollution monitoring and early warning device based on fish behavior. The early warning device includes an experimental reaction box. The experimental reaction box is sequentially provided with a biological early warning unit and a water quality check unit along the direction of water flow. The biological early warning unit and the water quality evaluation unit are separated by a water blocking device; it also includes a control device. The control device includes A central processing unit and an acquisition unit connected to the central processing unit, wherein the acquisition unit is a fin sensor, a CCD camera, a photoelectric sensor and a collision sensor, and the acquisition unit transmits the collected data signal to the central processing unit, and the central processing unit will The average swimming speed, average number of turns, average water depth and total impact frequency of fish collected in the biological early warning unit are compared with the established fish behavior response-water pollution degree black box model, so as to quantitatively determine the degree of water pollution .

Description

technical field [0001] The invention relates to a water pollution monitoring and early warning device based on fish behavior, and also relates to an early warning method of the water pollution monitoring and early warning device, belonging to the technical field of water environment protection. Background technique [0002] Sudden water pollution refers to the water pollution phenomenon in which the pollutants in the water body suddenly increase sharply in a short period of time due to man-made or natural disasters, and the deterioration rate is fast. features. With the continuous acceleration of urbanization and industrial development, sudden water pollution accidents will occur in many areas of our country, which will directly lead to the decline of water quality, the reduction of water biomass and the reduction of biodiversity, which will have a negative impact on my country's ecological environment and social economy. It has a great impact and has become one of the most ...
