Problems solved by technology

[0006] The purpose of the present invention is to overcome the defects that the traditional water quality online monitoring method can only carry out regular monitoring at key points and cannot realize real-time monitoring of water bodies, thereby providing a method based on differential filtering and three-dimensional space technology to monitor aquatic biological behavior ecological changes. A safe, efficient and economical online biosafety early warning method for water quality that can be monitored in real time, on-line and on-site

Embodiment 1

[0031] Embodiment 1, using the method provided by the present invention to carry out online biosafety early warning method for organophosphorus polluted water sources

[0032] In this embodiment, the magna larvae 48 hours after birth were selected as the test organisms, and their periodic behavioral rules including periodic breathing movements or changes in typical behavioral activities (swimming, swinging, turning, etc.) that occurred in cycles were monitored. One of the two pairs of electrodes of the biosensor generates low-voltage alternating current to form an electric field for the monitored water body; the other pair is the sensing electrode, which senses the change of the electric field caused by the behavioral movement of the larvae Daphnia magna. Different behavioral intensities can generate different electric fields. signal strength. The monitoring conditions of the water body are as follows: the flow rate of the monitored water body is 30 m / h, the turbidity is less ...

Abstract

The invention relates to a water quality online biological safety alarm method, comprising that using the object aquatic life with multiply motions as instructor, using differential fiber and three-dimension spatial technique to online detect the motion change of aquatic life before reaching a first pressure threshold (t1+t2), to evaluate the water condition biological system quality, to realize water quality safety biological safety alarm, that using the motion change or physiological reaction of the aquatic life to represent water quality. The inventive method can overcome the defects of traditional water quality online detect method which can only periodically detect at key point and fail to real-time detect water, therefore, the invention is based on differential filter and three-dimension spatial technique to detect the motion change of aquatic life, to real-time, online and on-site detect quality.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring and water body pollution control, and in particular relates to a water quality online biosafety early warning method based on differential filtering and three-dimensional space technology monitoring of aquatic biological behavior and ecological changes. Background technique [0002] All kinds of sudden accidents and abnormal operation of chemical plants will lead to unpredictable water pollution accidents. Therefore, continuous online monitoring of water pollution is very necessary. On-line biological monitoring technology is a technology gradually developed in response to the needs of water quality evaluation. So far, the technology applied to online water quality monitoring is mainly online physical / chemical analysis, and the online water quality monitoring and early warning technology using biological indicators is still in the exploratory stage. At present, some water qualit...
