Water pollution monitoring and early warning device based on fish behaviors and early warning method of device

Abstract

The invention discloses a water pollution monitoring and early warning device based on fish behaviors, and an early warning method of the water pollution monitoring and early warning device based on the fish behaviors. The early warning device comprises an experiment reaction box and a control device, wherein the experiment reaction box is provided with a biological early warning unit and a waterquality checking unit in the water flow direction in sequence, and the biological early warning unit is separated from the water quality checking unit through a water blockage device; the control device comprising a central processing unit and a collection unit connected with the central processing unit, the collection unit is composed of a fin sensor, a CCD camera, a photoelectric sensor and an impacting sensor, the collection unit transmits a collected data signal to the central processing unit, and the central processing unit contrasts the collected average swimming speed, average turning frequency, average activity water depth and total impacting frequency of fishes in the biological early warning unit with a constructed fish behavior reaction-water pollution degree black-box model, and therefore the degree of water pollution is judged quantitatively.

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 ...

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
