Problems solved by technology
[0002] At present, the traditional flow-type fish toxicity test devices in China basically use a large number of peristaltic pumps, heaters and agitators. During the use of these devices, due to mechanical friction, pressure or direct heat generation, the convection of the flowing water Influenced by the uncertainty of the drug ingredients or dissolved oxygen in the test, which reduces the accuracy and reliability of the test results

The invention provides a water-flowing type fish toxicity test system which comprises a fish water temperature environment regulation device and a fish toxicity test device, wherein the fish water temperature environment regulation device is a room temperature regulation device for regulating the indoor environment temperature; the fish toxicity test device comprises at least one ecological fish tank arranged along the vertical direction from bottom to top in a layered mode, solution mixers which are correspondingly connected with the at least one ecological fish tank one by one by virtue of guide pipes, medicine storage bottles which are correspondingly connected with the solution mixers by virtue of the guide pipes, and water supply tanks connected with the solution mixers by virtue of guide pipes; first flow controllers used for regulating the concentration of a medicine solution are arranged on the guide pipes connected with the medicine storage bottles and the solution mixers; and second flow controllers used for regulating the water flow are arranged on the guide pipes connected with the water supply tanks and the solution mixers. According to the system disclosed by the invention, a pump is completely avoided, the direct heating is not needed, heat generated by mechanical friction is avoided, the influence on medicines and dissolved oxygen is reduced, and the accuracy and the reliability of the test results are improved.
Description
technical field [0001] The invention relates to the field of test equipment, in particular to a flowing water fish toxicity test system. Background technique [0002] At present, the traditional flow-type fish toxicity test devices in China basically use a large number of peristaltic pumps, heaters and agitators. During the use of these devices, due to mechanical friction, pressure or direct heat generation, the convection of the flowing water The influence of the uncertainty of the drug ingredients or dissolved oxygen in the test results reduces the accuracy and reliability of the test results. Contents of the invention [0003] The object of the present invention is to provide a flow-type fish toxicity test system to solve the above-mentioned problems. [0004] An embodiment of the present invention provides a flowing water fish toxicity test system, comprising: a fish water temperature environment adjustment device and a fish toxicity test device; the fish water temper...
