Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution:Including babinet 1 and water distribution supervisor 5,1 inside points of babinet If for dried layer, the water distribution supervisor 5 runs through each layer of babinet 1, and the lower end of water distribution supervisor 5 is connect with cistern 8;Babinet 1 Each layer be equipped with culture apparatus 12, the culture apparatus 12 includes grid 2, and sink 6 is provided on grid 2, is placed in sink 6 Several experiment containers 3, are correspondingly arranged that there are one tubules 4 of sprinkling water above each experiment container at 2cm, watering tubule 4 is through water distribution branch Pipe 14 is connect with water distribution supervisor 5.1 bottom of babinet is equipped with universal wheel, can move freely.The material of babinet 1 is stainless steel plate and close Closure material.Clamshell doors are arranged in 1 front of babinet, and 1 bottom right-hand unit of babinet has compressor, 1 inside of babinet to be passed equipped with temperature The intelligent illumination plate of sensor and four sides, can be temperature automatically controlled and automatically controls light application ratio.1 bottom cistern 8 of babinet and waste liquid pool 10 and Compressor 11 is separated with 1 internal work room of babinet by steel plate and heat-barrier material, to ensure the leakproofness of box house.Bottom Steel plate trepanning is simultaneously furnished with sealing-plug, fit on water distribution supervisor 5.1 internal side wall of babinet is equipped with a large amount of buckles, can be according to experiment need It asks and grid 2 is placed in different height, the number of plies that setting experiment needs.Sink 6 is organic glass sink.
6 side wall of sink is equipped with outlet pipe 7 apart from 3 centimeters of bottom, when water is changed in 3 overflow of experiment container placed in sink 6 When the waste water being discharged is higher than outlet pipe 7, waste water is flowed out from outlet pipe 7 automatically, finally flows into the waste liquid pool of 1 bottom of babinet installation 10.3 side wall of experiment container is provided with spout hole according to height of water level needed for experiment, and strainer is stained on spout hole, avoids overflow Bioorganism is lost when changing water.Immersible pump 9 in cistern 8 is connected with intermittent timed switch, realizes auto-timing water-changing.And Cistern is internally provided with aeration head, and aeration head is connect with oxygen pump 13, ensures the dissolved oxygen of experimental water abundance.Waste liquid pool 10 goes out Water end (W.E.) is equipped with biochemical filtration cotton, flows into the waste liquid in waste liquid pool 10 by outlet pipe 7 from organic glass sink 6, passes through water outlet The filter cotton at end is pumped into drainage pipeline eventually by delivery hose by the dredge pump for being connected with intermittent timed switch.
This experimental provision is tested for sediment toxicity appraisal and evaluation, and biological subject chooses a kind of freshwater bivalve class, because This experiment carries out in the experiment container 3 of 3L, and each experiment container 3 bores one in one side wall from about 1 centimeters of top 1.6 centimetres of big holes of diameter.When being higher than outlet pipe 7 by the waste water being discharged when overflow system automatic water-replacing in sink 6, give up Water is flowed out from outlet pipe automatically, is finally flowed into the waste liquid pool 10 of 1 bottom of babinet installation.Water in cistern 8 by immersible pump 9, It is pumped into experiment container 3 by the water distribution supervisor 5 of installation, the every installation of range pipe 14 passes through watering there are six tubule 4 of sprinkling water Tubule 4 can control and change water flow velocity, cause to disturb to deposit when in order to avoid replacing overlying water automatically.Intermittent timed switch is set It is primary (about 90 minutes) to be set to every automatic water-replacing on the two.It every two days (should not mistake to the flow rate in each experiment container 3 Height, in order to avoid the too strong influence deposit stability of flow velocity) and the time calibrated to increase the overlying water of one third volume.Babinet 1 inside sets four layers altogether, and every layer can put 12 3L experiment containers 3.
This experimental provision is applied to marine sediments toxicity appraisal assessment (TIE) experiment.Experiment is with reference to U.S.EPA (USEPA) guilding principle carries out.Initial toxicity experiment is carried out to a certain point deposit and three kinds of screening agent additions are tested, every group Three Duplicate Samples of experimental setup.1 is pressed in 3L glass containers:Deposit and overlying water, every group of sample setting three is added in 4 (V/V) It is a parallel, 15 Corbicula flumineas are each placed in parallel into, exposure 10d, water temperature maintains 20 ± 1 DEG C during exposure.Dissolving in overlying water Oxygen, pH and conductivity measure once every three days, it is ensured that control group dissolved oxygen content >=2.5mg/L, pH is between 7.2~7.5, electricity Conductance is between 420~500 μ s/cm, not feeding during experiment.It is switched every two days by intermittent timed during experiment and is moved certainly Water is primary, changes water duration every time 90 minutes.Spin manifold temperature is set as 20 DEG C during experiment, and light application ratio is 16 round the clock:8, daytime light Illumination is about 100 luxs, and night illuminance is 0 lux.Initial toxicity is right respectively at 1,3,5,7,10 day during testing Indices are measured, and duration is tested to determine.Determine that experimental period is after 10 days, screening agent addition experiment was in toxicity on the 10th The measurement of indices is carried out after experiment.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
