The utility model relates to an evaluation pollutant is to simulation soil solution test device of earthworm toxicity, including the fluid -tight incubator of printing opacity, be provided with monitoring device in the incubator, the incubator is connected with the apparatus of oxygen supply, monitoring device is including setting up the camera in the incubator, the camera is connected with the computer through the converter, the apparatus of oxygen supply is including ventilating the pump, the pump of ventilating is linked together through breather pipe and incubator, be provided with the flowmeter on the breather pipe, incubator upper portion is provided with round -meshed case lid, the breather pipe run through stretch into the incubator behind the round hole on the case lid inside, compare with prior art, the utility model discloses there have with simple and convenient, the experimental repeatability of test device to be good very much, and the advantages such as sensitivity height of monitoring, has wide application prospect in the aspect of polluting soil ecological environment risk assessment.
Description
Technical field
The utility model relates to a kind ofly evaluates the simulated soil solution test unit of pollutant to earthworm toxicity.
Background technology
Traditional soil pollution experiment, because soil constituent is complicated, Soil Background significant difference, comparatively large to the interference of pollutant toxicity, the result that different soils shows is totally different, causes experimental provision complicated, experiment poor reproducibility.And the earthworm pollutant approach absorbed in soil is mainly dissolved in the effective constituent of simulated soil solution by its skin Passive intake.So exploitation a kind of be experiment thing for earthworm, experimental period is short, and favorable reproducibility and highly sensitive soil pollution experiment are significant.
Utility model content
The purpose of this utility model is for above weak point, provides a kind ofly to evaluate the simulated soil solution test unit of pollutant to earthworm toxicity.
The scheme that the utility model technical solution problem adopts is, a kind ofly evaluate the simulated soil solution test unit of pollutant to earthworm toxicity, comprise the fluid-tight incubator of printing opacity, be provided with supervising device in described incubator, described incubator is connected with apparatus of oxygen supply.
Further, described supervising device comprises the camera be arranged in incubator, and described camera is connected with computer by converter.
Further, described apparatus of oxygen supply comprises ventilation pump, and described ventilation pump is connected with incubator by snorkel, and described snorkel is provided with flowmeter.
Further, described incubator top is provided with round-meshed case lid, and described snorkel stretches into incubator inside after running through the circular hole on case lid.
Compared with prior art, the utility model has following beneficial effect: test unit is easy, test reappearance is good especially, and the sensitivity advantages of higher of monitoring, have broad application prospects in contaminated soil ecological risk assessment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model patent is further illustrated.
Fig. 1 is the structural representation of experimental provision;
In figure:
1-ventilates pump; 2-flowmeter; 3-case lid; 4-incubator; 5-camera; 6-converter; 7-computer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, a kind ofly evaluate the simulated soil solution test unit of pollutant to earthworm toxicity, comprise the fluid-tight incubator of printing opacity, be provided with supervising device in described incubator, described incubator is connected with apparatus of oxygen supply.
In the present embodiment, described supervising device comprises the camera be arranged in incubator, and described camera is connected with computer by converter.
In the present embodiment, described apparatus of oxygen supply comprises ventilation pump, and described ventilation pump is connected with incubator by snorkel, and described snorkel is provided with flowmeter.
In the present embodiment, described incubator top is provided with round-meshed case lid, and described snorkel stretches into incubator inside after running through the circular hole on case lid.
Specific implementation method:
(1) simulated solution of configuration containing soil liquid principal ingredient; (2) in simulated solution, add the environmental contaminants of variable concentrations, and number respectively, separately get a simulated solution not adding environmental contaminants and do experiment contrast; (3) simulated solution adding environmental contaminants that difference is numbered is added in different incubators, puts into incubator by after earthworm gut purge, earthworm is exposed in the middle of solution completely; (4) in incubator, oxygen is passed into by apparatus of oxygen supply, by the behavior reaction of camera observed and recorded earthworm in the simulated solution kind 48 hours of varying environment pollutant and fatal rate.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
