Description
Technical field
The present invention relates to aquatic animal exposure experimental provision and applications, more particularly, to a kind of aquatic animal toxicological experiment
System and application.
Background technique
1. being had at present using the method that zebra fish carries out organic matter toxicological test is that partial volume device hydrostatic is raised, parallel group is arranged
(same concentrations group) and control group, residual bait, excrement is sucked out in timing, and replaces testing liquid.2. using the flowing water group for dividing parallel group
It attaches together and sets raising, every parallel group independently filters residual bait, excrement, and replaces testing liquid.But the above method is 1. in test process
Soil pick-up is time-consuming: when test, Partial Species organic matter volatilizees from solution in test process or is adsorbed in excrement, residual bait, container
Wall etc., each container difference soil pick-up of parallel group, the difference for replacing solution amount respectively etc., will lead to molten in each parallel group container
Large variation occurs for liquid concentration, causes test solution concentration in each container of parallel group to form difference, serious reduce repeats test effect
Fruit.2. pollutant is easy to volatilize from solution or be adsorbed in excrement, residual bait, chamber wall etc., put down the above method during the test
Each container of row group absorbs residual bait excrement respectively, and each container of parallel group cannot carry out solution equilibrium very well, equally cause parallel group each
Solution concentration fluctuates in container, reduces and repeats test effect, and residual bait excrement heavy workload is sucked out.If volatile contaminant
Toxicity test, 1. 2. pollutant volatilization be easy to cause indoor pollution to method with method in experimentation, threatens experimenter's body
Health.
Chinese patent CN201821759U discloses the aquatic organism cultivating system that a kind of drip water-feeding type is used for toxicological experiment,
Including bracket, supporting layer, cultivation flume, return flume, purification tank for liquid waste, filtering cloth jar and water-supply-pipe with multilayer support layer
And control valve；It is equipped with water storage box in cradle top, the dribble-feed water inlet pipe of cultivation flume is made up of hydraulic pipeline and control valve
Road；Unidirectional cultivation water system is constituted further through drainpipe outside cultivation flume and breeding trough and purification tank for liquid waste；In the support
Layer is equipped with the water bath of water temperature in controllable breeding trough, and the cultivation flume is placed in water bath；In addition, described
Water bath by the water bath water inlet, the water bath overflow plate that are arranged on water bath, and with the matched water bath of water bath
Backflash, water bath return pipe, filtering cloth jar constitute temperature control circulator bath system；It is furnished with charge valve in the cultivation flume top.
Water system in the patent is connection water-supply-pipe and control valve group by being connected on each cultivation flume at from top to bottom
Water system, the solution concentration of toxicological experiment is then consistent, and cannot achieve parallel exposure in groups.And this system is without dirt
Object collector unit, the cleaning that not can guarantee exposed environments are stablized, and the breeding of aqueous bio is unfavorable for.
Chinese patent CN102830202A discloses a kind of closed static aquatic organism toxicity experiment device, including transparent
Experiment container, oxygen supply container, faecal collecting device, the transparent experiment container upper surface are openable and closable cover board,
It is equipped with oxygen supply container in the transparent experiment container, is that funnel-form connects in the middle part of the transparent experiment container lower surface
Component, the funnel-form connecting component lower end connect faecal collecting device.Although the experimental provision can the row of collection at any time
Object is let out, bottom center is funnel-shaped, and lower end connects faecal collecting device, but needs manually opened discharge/collection, and exposes body
It is that solution will also be flowed out with discharge/collection process, such as exposure experiment continues, then needs again to return to solution after being separated by solid-liquid separation
In exposure container.
Therefore, the prior art cannot achieve aquatic animal toxicological test device automatic pollutant removal and parallel exposure etc. in groups is crucial
Problem.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind being capable of high quality reality
Now the liquid equilibrium in more parallel group processing and automatic pollutant removal, while cost of labor and human interference are reduced, it can effectively reduce
Pollutant, which volatilizees, leads to the aquatic animal toxicological experiment system of indoor pollution, and it is real which can be used for aquatic animal toxicity
