A sewage sampling device for agricultural production

Abstract

The invention discloses a sewage sampling device for agricultural production, which belongs to the field of sewage sampling devices. It is a sewage sampling device for agricultural production. The refrigeration device continuously releases low-temperature gas, and the low-temperature gas passes through the hollow groove after opening the cover body Rapidly diffuse in all directions, and then slowly diffuse in the thermal insulation fiber until the cold air in the thermal insulation fiber is completely diffused, and the thermal insulation fiber, that is, the sealing curtain in the storage hole and other structures are set up like the fur on the biological surface, isolating the thermal insulation area of ​​the main body of the storage box The heat exchange with the outside world can effectively realize the heat preservation effect of the heat preservation area in the main body of the storage box, reduce the power consumption of the refrigeration device, and make it convenient for technicians to sample and store agricultural sewage. At the same time, the agricultural sewage samples can be stored for a long time , it is not easy to cause some active substances in the sample to reproduce by itself due to its long storage time, and it is not easy to affect the normal detection of sewage.

Description

technical field [0001] The present invention relates to the field of sewage sampling devices, and more particularly, to a sewage sampling device used in agricultural production. Background technique [0002] Agricultural sewage refers to sewage or liquid substances that are discharged during the process of crop cultivation, livestock raising, and agricultural product processing, and affect human health and environmental quality. At the same time, the impact on the environment is gradually increasing, and it is easy to affect the harvest of crops, especially the crops are mostly used as food supply. The harmful substances accumulated in the crops polluted by sewage will accumulate in the human body along with the food chain, seriously affecting people. Therefore, sampling and testing of agricultural sewage and pollution control have become an important part of agricultural production. [0003] Fur is usually the first line of defense for animals to resist the severe cold. Wh...

Problems solved by technology

[0004] The traditional sampling of agricultural sewage is mostly carried out directly in an open sampling environment using simple sampling containers such as plastic bottles, and then the samples are transferred to the corresponding testing laboratory for testing. Since the sampling environment is originally a relatively open environment, Therefore, the requirements for sampling are relatively low, and the requirements for storage and transfer are also relatively low, which has little impact on the detection of inactive substances such as heavy metal ions, but in the detection of agricultural sewage, active substances such as algae are also detected. Important indicators, these algae are very easy to reproduce in the sampling container by themselves. Once the sample is taken for a long time before being sent to the test, it is very easy to seriously inaccurate the test results of the active substance due to the above reasons, which has a great impact on the sewage test.
