experiment example 1

[0042] Effects of different turbidity and temperature water bodies on Japanese medaka behavior changes and changes in water body turbidity and temperature after pretreatment of the present invention:

[0043] The turbidity and temperature of the water body have very obvious effects on organisms. In order to further clarify the quantitative relationship between behavioral changes and turbidity and temperature, this experimental example first tested the behavioral effects of different temperatures and turbidity on Japanese medaka. On this basis, the treatment effect of the pretreatment system of the present invention on water turbidity and temperature is verified.

[0044] Indicator organism: Japanese medaka, with a body length of about 3cm. The biosensor adopts the size of 5cm in diameter and 5cm in length, and 3 tails are used in each sensor.

[0045] Before the start of the experiment, the biosensor signal without test organisms was first reset to zero, and then began to pass...

experiment example 2

[0054] On-line biological monitoring of sudden methomyl pollution in water bodies

[0055] In the case, different concentrations of methomyl were used for water exposure, and the water flow rate through each biosensor was controlled to 25mL / min by a small-flow water flow rate automatic control system. A total of 8 groups of sensors were used to carry out the experiment on the change of biological behavior indicators.

[0056] Indicator organism: Japanese medaka, with a body length of about 3cm. The biosensor adopts the size of 5cm in diameter and 5cm in length, and 3 tails are used in each sensor.

[0057] Before the start of the experiment, the biosensor signal without test organisms was first reset to zero, and then began to pass through water bodies with different concentrations of pollutants in turn. Displayed by means of different frequency behaviors formed after Fast Fourier transform. Use 0.1, 1, 5, 10 TU (toxicity units) of methomyl (1 TU = 0.2 mg / L) water body for o...

Abstract

The invention discloses a biological monitoring system and a biological monitoring method for monitoring a sudden change of high-turbidity and low-temperature water quality. The system is characterized by comprising a water pretreatment system, a signal acquisition and analysis system and a signal transmission system; by internally-designed turbidity-removing and temperature-raising measurements, the technology and the system can ensure that the monitored water is a normal living environment for an indicating creature under a high-turbidity and low-temperature condition; on a basis of detecting and analyzing biologic behavior, on-line monitoring for comprehensive toxicity of the water can be realized; and according to a built-in standard change trend of the biologic behavior, the behavior change of the indicating creature is analyzed, the biologic behavior in the monitored water is ensured to be true, the change condition of the water quality is accurately represented, and the requirements of different monitoring departments for a stable long-time monitoring are met.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a biological monitoring system and monitoring method that can be applied to sudden changes in high turbidity and low temperature water quality. Background technique [0002] The wide application of chemicals has brought serious problems of environmental pollution, and there are also many hidden dangers in the production, transportation and storage of chemical substances. The accidental leakage of toxic and dangerous chemicals into the water environment will not only cause great harm to human beings, pose a threat to the survival of organisms, but also destroy the balance of the water ecosystem. Sudden water pollution accidents will discharge a large amount of pollutants in an instant or in a short period of time, causing serious pollution and damage to the water environment, and causing heavy losses to people's lives and national property. Different ...
