Abnormal water quality detection and grading alarm method based on the stress behavior of red zebrafish

Abstract

The invention discloses a water quality abnormity detection and grading alarm method based on red zebra fish stress behaviors. The method comprises steps as follows: 1, a toxicity test is performed on red zebra fishes, and behavior characteristic parameters of the red zebra fishes under the normal condition, in the initial phase of pollution and in the last phase of pollution are quantitatively analyzed; 2, significance testing is performed on data under the normal condition and in the initial phase of pollution and data in the initial phase and the last phase of pollution, and parameters with significant difference in contrast of the two groups of data are selected as water quality monitoring indexes; 3, alarm threshold values are set and comprise a primary threshold value and a secondary threshold value; 4, the parameters are compared with the threshold values, and an alarm is given when two or more parameters reach the primary threshold value simultaneously; 5, when two or more parameters reach the secondary threshold value simultaneously, whether primary alarming is performed is judged, if yes, a secondary alarm is given, and otherwise, no treatment is performed. The water quality change can be effectively monitored in real time, grading alarms are given when pollution happens, and the alarm accuracy is increased.

Description

technical field [0001] The invention relates to a method for detecting water quality, in particular to a water quality abnormality detection and grading alarm method based on the stress behavior of red zebrafish. Background technique [0002] The water pollution problem in today's society is becoming more and more serious, affecting human life and ecological balance, and drinking water safety has become one of the issues that people pay more and more attention to. Therefore, many scholars are devoted to the research of water quality monitoring methods. Currently, existing methods include physical and chemical analysis and biological monitoring. The physical and chemical analysis method relies on manual collection of water samples for physical and chemical analysis. This process is time-consuming and labor-intensive, and cannot meet the real-time requirements. The biological monitoring method judges the water quality status by analyzing the behavior and physiological charact...

AI Technical Summary

Problems solved by technology

[0003] However, at present, many studies on biomonitoring methods focus on the acute toxicity test of fish, and only analyze the two situations of normal conditions and short-term abnormal conditions, and the analysis of various behavioral parameters of fish is not comprehensive, mainly for The speed and acceleration of fish movement, no analysis of the position distribution of fish schools

There are also many problems in the alarm process. For example, if the degree of water pollution is not graded, false alarms and missed alarms are prone to occur, and the change process of pollution over time cannot be reflected.
