Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of microbial degradation detection, and particularly relates to a deltamethrin detection device for microbial degradation. BACKGROUND

[0002] Deltamethrin is widely used in pest control and pond cleaning in aquaculture due to its broad insecticidal spectrum, fast effect and low toxicity to mammals. However, with the increase of deltamethrin dosage, its residue in aquaculture water is also increasing, which seriously endangers the water environment. Deltamethrin has the characteristics of light resistance and heat resistance, and its residue time in the natural environment is relatively long, which is easy to be enriched by aquatic animals and plants, and has a serious impact on aquatic organisms, aquatic product quality and safety, and human health. In order to realize green and healthy aquaculture and protect human health, the pesticide residue degradation technology based on biological remediation has become a research hotspot at present. In order to ensure the accuracy and effectiveness of microbial degradation, the content of deltamethrin in water must be detected before and after the operation of the operator, and then effective microorganisms are selected for degradation of deltamethrin.

When the sampling assembly 24 is pushed to the locking position, the pressing member 222 is released and the locking member 224 moves in a second direction opposite to the first direction under the action of the elastic member 223 so that the clamping groove 242 is engaged in the sampling assembly 24, thereby fixing the sampling assembly 24 in the mounting shell 21.

Preferably, the mounting member body 421 is substantially in the shape of a circular plate. The mounting column 422 comprises a cylindrical portion 424 and a non-circular portion 425 connected between the cylindrical portion 424 and the mounting member body 421. In the present embodiment, the diameter of the cylindrical portion 424 is greater than the dimension of the non-circular portion 425 along the radial direction of the cylindrical portion. The non-circular portion 425 is capable of being engaged in the clamping groove 242. The uppermost one of the plurality of sampling bottles 41 is mounted in the connecting hole and the other sampling bottles are sequentially arranged on the lower side of the previous sampling bottle.

[0040] Referring to Figure 5 and Figure 8The sampling bottle 41 comprises a sampling bottle body 411, a second filter 412 installed on one side of the sampling bottle body 411, and a shielding member 413 movably installed on the sampling bottle body 411. Preferably, the sampling bottle body 411 is provided with a through hole at the position corresponding to the second filter 412, and the shielding member 413 is blocked on the through hole.

Preferably, the two ends of the receiving groove 111 are respectively provided with stop plates, and the shielding member 413 is limited in the receiving groove 111 by the stop plates. When the shielding member 413 blocks the through hole, the second inclined surface 133 abuts against the stop plate, and under the action of the corresponding stop plate and the second inclined surface 133, the inner side of the shielding member body 131 is reliably pressed towards the through hole, thereby blocking the through hole.
