Semi-static temperature-controlled fish toxicity test device

Abstract

The invention discloses a semi-static temperature-controlled fish toxicity test device. The device includes: a semi-static control unit. After monitoring that the fish tank is put into the test fish, the cumulative test time is less than the test time threshold, and the predetermined volume of water in the fish tank is replaced according to the monitoring cycle, and the toxicity test unit is notified. The test time threshold is to end the test; the toxicity test unit, according to the requirements of the semi-static temperature-controlled fish toxicity test, configures the number of fish tank groups and the number of fish tanks required for each group; prepares the test water in the fish tank according to the volume of the test water; Add medicine to the test water; put the tested fish; heat the temperature control unit to control the test water temperature within the set temperature range; aeration and oxygenation unit to oxygenate and aerate the fish tank; light unit, according to the toxicity of fish Test standard, adjust the light of the toxicity test unit through the illuminator. By applying the invention, the constant temperature in the water environment and the batch operation of the test can be realized.

Description

technical field [0001] The invention relates to water environment ecological technology, in particular to a semi-static temperature-controlled fish toxicity test device. Background technique [0002] Water is the basis for human survival, and the quality of water environment is closely related to human health and development. With the rapid development of social economy, the global demand for metals is also increasing, making the mining and smelting of metal deposits present a geometric growth trend. The heavy metals used in large quantities enter the water environment through various channels, causing ecological pollution of the water environment, leading to the deterioration of the water environment, and posing a serious threat to the ecological safety of the water environment and human health. For example, at present, a large amount of industrial waste and sewage are discharged into rivers and lakes without effective sewage treatment, which not only poses a serious threa...
