Abstract
The embodiment of the utility model discloses an absorption and desorption device for comprehensive toxicity detection. Shading steps are arranged on an upper plate, a lower plate, a front cover plate, a side cover plate, a main frame and a photomultiplier fixed block of the absorption and desorption device to well shade outside light. Double layers of shading steps are arranged on the front cover plate which is frequently opened so that the shading effect of the device is better. In addition, a sealing strip is arranged on the front cover plate, when the front cover plate is closed, the sealing strip on the front cover plate is embedded in a sealing strip groove on the frame, which is formed by the upper plate, the lower plate and the side cover plate, thereby the device has better sealing performance and can prevent light from entering inside.
Description
Technical field
The utility model relates to comprehensive toxicity detection technique field, particularly relates to a kind of the vacuum device used of comprehensive toxicity detection that be used for.
Background technology
In recent years, the kind of toxic substance increases gradually, and total emission volumn continues to increase, and the environmental hazard that causes thus strengthens gradually.China has strengthened the management intensity of aspects such as river and tap water protection, industrial wastewater discharge, in order to ensure the water source quality, also will include water quality toxicity in control criterion in this year.Along with the development of environmental, the investigator adopts microorganism (as photogenic bacterium, nitrobacteria, active sludge etc.) as the bio-sensing material more, analysis water-like toxicity.Wherein photogenic bacterium is because the simplicity of its higher sensitivity and operation, be suitable for on-line analysis, utilize the comprehensive toxicity in the photogenic bacterium detection water, the luminous power of this bacterium can be represented the vigorous degree of metabolism, any toxicity, be the metabolism that bio-toxicity or chemical toxicity all can suppress bacterium, and then the inhibition luminous intensity, by measuring change of luminous intensity, just can detect toxic size.
Utilize the comprehensive toxicity in the photogenic bacterium detection water, need detected water sample and pure water simultaneously respectively at mixing by certain proportion with this bacterium, determine the toxicity per-cent of detected water sample by the luminous intensity of comparing these two mixtures, two channels detects simultaneously, and whole detection system places optics sealing darkroom fully.Because the luminous intensity of photogenic bacterium is very faint, and directly influences the result that toxicity detects, so proofing unit must reach good sealing effectiveness, prevents the influence of extraneous light.There is certain interval between the web plate of the vacuum device used external frame in the existing detection system, and the frequent unlatching of front shroud, make the inner detection effect of extraneous light influence.
