Problems solved by technology

[0002] At present, a large amount of industrial excrement and waste water are discharged into rivers and lakes, causing large-scale pollution of rivers and lakes. The life of fish in the river is seriously threatened, and the sewage also threatens the safety of downstream drinking water sources.
Although many factories now carry out sewage treatment before discharging wastewater, there are still certain toxic substances in the treated sewage, which still cause toxicity to fish. Unfortunately, there is no method for directly measuring fish in flowing rivers. toxic-like device

Embodiment Construction

[0011] see figure 1 , the present invention provides a dynamic flowing water fish toxicity test device, which mainly includes an illumination system 1, a circulating water tank 2, a circulating water pump 3, a dosing peristaltic pump 4, an oxygenator 5, a dosing container 7, a magnetic stirrer 8. Fish tank 9. Temperature control system 10. The fish tank is provided with several flow control ports 13.

[0012] Several fish tanks are provided in the test device, and each of the three fish tanks is a parallel test group. In the parallel test group, the one fish tank is a blank test, and the other two fish tanks are a dosing test. At least two parallel test groups are set in the test device, and a plurality of parallel test groups can be added to the test device according to actual test needs.

[0013] The actual test water volume of the fish tank can be greater than 5L, at least 10 test fish less than 4 grams can be accommodated, and each test group has more than 10 fish, and th...

The invention is characterized in that the test device is a frame which is internally provided with a plurality offish tanks; each fish tank is respectively matched with a corresponding drug feeding container and a drug feeding peristaltic pump; the drug feeding container, the fish tank and the drug feeding peristaltic pump are connected mutually by drug conveying pipes; each fish tank is also respectively matched with a corresponding circulating water tank and a circulating water pump; and the fish tank, the circulating water tank and the circulating water pump are connected mutually by liquid conveying pipes.

Description

technical field [0001] The invention relates to a dynamic flowing water type fish toxicity test device. The equipment is easy to operate and can ensure the reliable conduct and completion of the experiment. Background technique [0002] At present, a large amount of industrial excrement and wastewater are discharged into rivers and lakes, causing large-scale pollution of rivers and lakes. Fish life in rivers is seriously threatened, and sewage also threatens the safety of downstream drinking water sources. Although many factories now carry out sewage treatment before discharging wastewater, there are still certain toxic substances in the treated sewage, which still cause toxicity to fish. Unfortunately, there is no method for directly measuring fish in flowing rivers. Toxic devices. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fish toxicity test device in simulated dynamic running w...
