Uniform lighting device for alga culture based on aquatic organism ecotoxicity evaluation

Abstract

The invention discloses a uniform lighting device for alga culture based on aquatic organism ecotoxicity evaluation. The uniform lighting device comprises an incubator body, wherein an automatic temperature control system is arranged inside the incubator body; a plurality of net plate layers parallel to one another are arranged inside the incubator body through a height adjusting device; the net plate layers are structural net layers with an inner cavity consisting of a lower net plate layer and an upper net plate layer; a plurality of alloy transverse rods perpendicular to the incubator body are uniformly arranged on the upper surface of the upper net plate layer of the net plate layers; a plurality of stripy light sources which are arranged uniformly are arranged on the lower net plate layer inside the net plate layer; the positions and the number of the stripy light source correspond to those of the alloy transverse rods. By adopting the uniform lighting device for alga culture based on aquatic organism ecotoxicity evaluation, the lighting condition for acute toxicity of algae can be controlled, and thus culture in an incubator can be subjected to effective light sources of same intensity.

Description

technical field [0001] The invention relates to a uniform illumination device for algae cultivation based on the ecotoxicity evaluation of aquatic organisms, which is mainly used for the cultivation of algae and other organisms for ecotoxicity evaluation, and belongs to the fields of ecology and ecotoxicology. Background technique [0002] In environmental monitoring and ecological risk assessment and prediction research of chemicals, the chemical detection of pollutants alone cannot actually reflect the impact of chemical pollutants discharged into water bodies on the ecosystem. An essential step in product risk. Among them, the acute toxicity test of algae is one of the most commonly used standard methods, which provides a scientific basis for the formulation of environmental benchmarks and emission standards. In this method, among the quality control indicators of the reliability of the toxicity evaluation results, it is required that the algae grow under uniform experim...

Problems solved by technology

In the traditional light incubator sold on the market, the light source comes from the upper part or the left and right sides of the incubator body, which cannot provide the same intensity of light to the cultured cells placed in different positions. Usually, the closer to the middle of the incubator, the higher the light intensity. At the same time, the light source from the top of the incubator or the left and right sides of the incubator has different light uniformity around the culture in the incubator.
