#$%^&*AU2020101177A420200730.pdf#####Abstract The present invention discloses a flow-type toxicity test device for aquatic biological reference testing organisms, which comprises three units such as a test water preparation unit, a flow-type toxicity test unit and a toxicity effect monitoring unit, wherein the flow-type toxicity test unit comprises a test system, a circulation system, a filtration system, an automatic sampling system, a water replenishing and automatic dosing system, and an automatic feeding system. Different water quality parameters and conditions can be set independently according to the differences in the toxicity test conditions and the differences in habits of the reference testing organisms, to meet the flow-type toxicity test of the aquatic biological reference testing organisms, without polluting the environment. The application of the device can accelerate the formulation of aquatic organism references and related work of reference testing organisms, reduces labor cost and human errors in the process, and has good scientific research value and application benefits.Drawings of Description Test water preparation unit 1 Test sys Flowrate adjusting system 221 0 -- Circulation system 22 Oxygenation system222 -Filtration system 23 - Flow-type toxicity test unit 2 Automatic sampling system 24 Water replenishing and automatic dosmeL system 25 Automatic teedmng 3 ----~- system 26 CL Toxicity effect Liquid level gauge 27 monitorina unit 3 -Lighting system 28 Fig. 1 1
