Description
Technical Field
The utility model relates to the technical field of pesticide industry, in particular to a biological detection device for pesticide wastewater and a microcystis aeruginosa carrier.
Background
The pesticide industry is one of the main industries of the chemical industry. At present, nearly 2000 pesticide manufacturers exist in the whole country to produce more than 200 pesticides, the annual yield is up to 80 ten thousand tons, and the second place in the world. The pesticide wastewater refers to wastewater discharged by pesticide production enterprises in the pesticide production process. The pesticide wastewater has high yield and is mainly divided into benzene-containing wastewater, organophosphorus-containing wastewater, salt-containing wastewater, phenol-containing wastewater, heavy metal-containing wastewater and the like.
The detection method for the treated pesticide wastewater comprises the following steps: chemical analysis: analysis using chemical reagents and equipment allows the detection of the content of the relevant components in the wastewater. Common chemical analysis methods include High Performance Liquid Chromatography (HPLC), gas Chromatography (GC), and the like. Spectroscopic analysis: the related components and the concentration in the wastewater are detected by utilizing spectrum technology, such as ultraviolet-visible absorption spectrum, infrared spectrum, mass spectrometry and the like. The method has the advantages and disadvantages that: the advantages are that: the accuracy is high, and the content of each component can be accurately measured. Disadvantages: the operation technology is high in requirement, long analysis time is required, and the pretreatment of the wastewater sample is complicated.
Biological detection methods are detection methods that differ from chemical analysis and spectroscopy. The method has the advantages that the toxicity of pesticide wastewater to organisms can be directly evaluated, and the method has strong operability and instantaneity; the disadvantages are: for certain pesticide components, the indicator organism may be insensitive or inapplicable, a longer detection period is required, and the detection result is greatly influenced by environmental factors.
In order to find out whether water contains high concentration heavy metals, microcystis aeruginosa (Microcystis aeruginosa) is a blue algae (cyanobacteria) which is a common freshwater algae and is easy to form bloom, especially in a water body rich in nutrients. It exists in the form of a blue-green filiform cell aggregate with a diameter of about 2-8 microns. It belongs to unicellular algae, but can form large populations, called microcystis clusters. Each microcystis contains a number of unicellular algae within the microcystis mass, as well as a large amount of extracellular polysaccharide material. When the microcystis aeruginosa cells are in water with heavy metal elements, the cell morphology changes. In particular, in heavy metal contaminated environments, the cell morphology of microcystis aeruginosa changes, and they obviously show abnormalities such as discoloration, cracking and shape distortion. This is because heavy metals interfere with the membrane structure and cell wall synthesis of algae, resulting in abnormalities in cell structure. By utilizing the sensitivity characteristic, especially the fading characteristic, of the microcystis aeruginosa to heavy metals, whether the water contains heavy metals with higher concentration can be quickly found out.
However, in the prior art, if the treated pesticide production wastewater has poor treatment effect, the microcystis aeruginosa can be obviously changed in color and form under the condition that heavy metals are not effectively removed. However, even if the dispersed microcystis aeruginosa changes color and deforms, the microcystis aeruginosa is not easy to observe by naked eyes, and the accuracy and timeliness of detection can be greatly affected.
