Embodiment 1

[0029] Take 5 healthy loaches with similar body and weight, numbered 1-5 respectively. According to Table 1, five groups of experiments were carried out.

[0030] Table 1 Addition amount of experimental rice vinegar in each group

[0031]

[0032] The specific experimental plan is as follows:

[0033] (1) First, use a plastic bucket to hold 5kg of clear water, and put a loach in it;

[0034] (2) Waiting for the loach to be quiet and the water surface no longer fluctuates, then the hydrophone starts to continuously collect sound wave signals, and at the same time, video record the stress behavior of the loach with photographic equipment;

[0035] (3) After the signal was collected for 5 minutes, tap the wall of the bucket as a signal to add vinegar, and at the same time, add rice vinegar mixed with 2ml of red ink as a tracer into the water. Refer to Table 1 for the amount of rice vinegar added. The place where rice vinegar is added should be as far away from the loach as p...

Embodiment 2

[0056] Take 5 healthy crabs with similar body and weight, numbered 1-5 respectively. According to Table 1, five groups of experiments were carried out.

[0057] The specific experimental plan is as follows:

[0058] (1) First, use a plastic bucket to hold 5kg of clear water, and put a crab in it;

[0059] (2) Wait for the crabs to be quiet and the water surface to stop fluctuating, then use the probe to continuously collect acoustic signals, and at the same time use a camera to record the stress behavior of the crabs;

[0060] (3) After the signal was collected for 5 minutes, tap the wall of the bucket as a signal to add vinegar. At the same time, add rice vinegar mixed with 2ml of red ink as a tracer into the water. Refer to Table 1 for the amount of rice vinegar added. The place where the rice vinegar is added should be as far away as possible from the crabs;

[0061] (4) The recording and signal collection time is 30 minutes. If the crab’s stomach is facing up and there i...

Abstract

The invention discloses a biological sound wave water quality safety monitoring method. Organisms will generate stress response in a polluted water body, and thus strong sound wave signals can be generated. Due to different pollution levels and different time exposing to pollutants, organisms will have different stress states, and the sound wave signals are different under different stress states. During the application process, a digital camera technology is used to analyze the sound wave signal energy so as to determine the different stress state of organisms in a water sample and corresponding characteristic peaks in a sound wave signal energy diagram. Then according to the sound wave signal characteristic peaks, the stress states of organisms can be determined directly. The sound wave monitoring system is simple and convenient, and will not affect the behavior of tested organisms in the water body and the living environment. The method can monitor the biological stress response and has the advantages of green, environment-friendliness, realtime online detection, agility, and reliability.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a method for monitoring water quality safety with sound waves. Background technique [0002] Water is one of the important resources for the survival of life on earth. However, with the development of human material civilization, rivers, rivers, lakes, seas, etc. are constantly being polluted, and water pollution has become an urgent problem to be solved. Polluted water will destroy the soil, affect the growth of crops, cause production reduction, and endanger the growth and reproduction of aquatic organisms, resulting in a large reduction in production, death, and even extinction of fish and shrimp, bringing huge economic losses to agriculture and fishery. Therefore, it is of great significance to find a water quality monitoring method that can monitor on-line in real time and realize early warning in order to protect the environment and reduce economic losses c...
