Water quality on-line safe prealarm system and method based on aquatic organism avoidance behavior

Abstract

The invention relates to a water quality online security early warning system and method thereof. The water quality online security early warning system comprises a biology avoidance behavior sensor which consists of two testing tubes, wherein, the two tubes are communicated through a two-way in the middle and parallel with each other; the two tubes are respectively provided with two groups of stainless steel monitoring electrodes, each group of electrodes consists of a signal transmitting electrode and a signal receiving electrode, wherein, the signal transmitting electrode forms a positive rotation low voltage alternating electric field in the testing tube, and the signal receiving electrode can induce changes of the electric field; the changes of the electric field are transmitted to a signal collecting device, and displayed through a display after being processed. The invention can display behavior change signal of a tested biology with the mode of electrical signal received from multi-point monitoring, can achieve online biology monitoring of original position, online and real time via analyzing and evaluating the electrical signal, and can warn early against unknown contaminants in water body, and has very important indicating effect for the investigations of environmental pollution, in particular for paroxysmal and severe accidental changes.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a water quality online safety early warning system and method. Background technique [0002] The wide application of chemicals, especially chemical pesticides and heavy metals, has brought about environmental pollution problems, and there are many hidden dangers in their production and transportation. The accidental leakage of toxic and dangerous chemicals into the environment will cause great harm to human beings at any time and pose a threat to the survival of living things. Man-made water poisoning also threatens the survival of aquatic organisms and the safety of human drinking water all the time. All kinds of sudden accidents and abnormal operation of chemical plants will lead to unpredictable water pollution accidents. An effective early warning system for environmental quality is needed to monitor sudden pollution accidents of the water envir...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome that the existing online biological monitoring technology for water quality will increase the measurement error due to factors such as water transparency, water flow velocity, and illumination, and can only realize two-dimensional monitoring of organisms, and cannot monitor organisms in The deficiencies of comprehensive evaluation and analysis of behavioral changes in three-dimensional space, so as to provide a method based on the tendency of aquatic organisms to avoid behavior changes in polluted water bodies, and comprehensively apply changes in biological movement laws and changes in electric field signals of different frequencies , and a water quality online biosafety early warning system and method for multi-point monitoring of biological movement behavior
