Problems solved by technology

The Microtox toxicity test system can only conduct regular monitoring at key points, and cannot realize real-time monitoring of water bodies; the planar camera system can record the behavior changes of organisms in a plane in real time, but lacks three-dimensional space changes, and cannot cover the ecological changes of biological behavior. regular characteristics; the MFB monitoring system can achieve the purpose of online monitoring by monitoring the regular changes in biological behavior, but it cannot accurately reflect the changes in the movement behavior of the tested organisms in different periods; BEWs also realize online monitoring of water quality through online monitoring of biological behavior changes, but this The system needs an external water flow control system to delay the real-time monitoring time of monitoring water bodies. At the same time, the system cannot solve the problem of water body control well, and it is difficult to meet the needs of long-term online monitoring
Therefore, it is urgent to develop an efficient, economical, accurate and long-term online biomonitoring technology for water bodies when traditional methods and existing online biomonitoring technologies are difficult to meet and meet the requirements of online environmental monitoring of water bodies.

experiment example 1

[0041] Behavior changes of daphnia magna exposed to different concentrations of parathion, refer to figure 2 Shown:

[0042] In order to verify the impact of sudden water pollution on the behavior of aquatic organisms, water bodies with parathion concentrations of 0.07ppm, 0.015ppm, 0.002ppm and 0.001ppm were used as the monitored water bodies, and Daphnia magna was used as the tested organisms.

[0043] Test organisms: Daphnia magna, adults, 5 per sensor.

[0044] The biosensor is realized by using cylindrical black PVC plastic with a copper coil wound on the inner wall, with a diameter of 50mm and a length of 50mm. 8 parallel sensors are used, 2 of which are used as controls, and the remaining 6 are used to monitor the direct passage of water bodies. The comprehensive monitoring of water quality changes adopts a 24-hour monitoring cycle. The water flow rate in a single biosensor is 25mL / min. The above-mentioned standard water body is obtained by aerating tap water for 2...

experiment example 2

[0050] The effect of dichlorvos pollution on biological behavior changes, refer to image 3 Shown:

[0051] In the case, different concentrations of trichlorfon 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 6 groups of sensors were used to conduct the experiment on the change of biological behavior indicators. Among them, 2 groups of control water were obtained through activated carbon filtration, and the other 4 groups directly flowed into the monitored water body. During the exposure process, keep the physical and chemical indicators of the water in line with the normal living conditions of daphnia magna: temperature 20±2°C, turbidity 2NTU, light 3000Lx, pH 7.5, etc.

[0052] Test organisms: Daphnia magna, adults, 5 per sensor.

[0053] Biosensor: Use cylindrical transparent plexiglass as the main body, with a length of 20mm and a diameter of 15mm,...

Abstract

The invention provides a water quality mutation-creature behavior index monitoring system and a monitoring method thereof. The water body quality condition is analyzed at real time by monitoring the behavior index change of the creature, and the online creature monitoring of the water body sudden pollution accident is realized. The system provides a plurality of platforms, and provides the control of water body monitoring. Meanwhile, the water flow balanced distribution of different creature sensors of the monitoring technology of the water quality mutation creature behavior indexes is realized by the water flow controller of the system, and the influence on the monitoring result caused by the creature behavior change caused by water flow changes is avoided.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a monitoring system and a monitoring method for biological behavior indicators of sudden changes in water quality. Background technique [0002] At present, in view of the frequent occurrence of sudden water pollution accidents at home and abroad, the online biological monitoring technology of water quality for sudden water pollution accidents is in a period of vigorous development. The online biological monitoring technology for sudden water pollution can analyze the change of water quality in real time by monitoring the response of a certain biological index online, and make a judgment on the comprehensive toxicity of the water body, making up for the online monitoring and analysis of water quality changes that rely solely on physical and chemical monitoring indicators of the water body. insufficient. At present, online biomonitoring technologies b...
