Rapid treatment device for water sample for environmental monitoring experiment

Abstract

The invention discloses a water sample rapid treatment device for environmental monitoring experiments, and belongs to the technical field of water sample treatment.According to the scheme, when a temperature sensing module senses that the temperature in a water storage tank rises, potassium nitrate powder filled in a cooling column is gradually released in a segmented mode; the potassium nitrate powder is dissolved in the distilled water in the liquid storage cavity to absorb a large amount of heat, so that the temperature of the water sample in the water storage tank can fluctuate within a specified range for a long time, the damage of the water sample caused by heat accumulation is effectively reduced, and meanwhile, the potassium nitrate powder is prevented from directly entering the water storage tank to pollute the water sample; the two-way magnetic ball is movably embedded in the semicircular plate, and the two-way magnetic ball always filters a water sample on the same side when the semicircular plate moves up and down by utilizing attraction and repulsion of an electromagnet to a magnetic ring in the semicircular plate and matching with attraction of the electromagnet to an upper magnetic ball clack and a lower magnetic ball clack; and the water sample is effectively prevented from being polluted due to the fact that filtered impurities are impacted down again during reverse filtering.

Description

technical field [0001] The invention relates to the technical field of water sample processing, in particular to a rapid processing device for water samples in environmental monitoring experiments. Background technique [0002] The components contained in environmental water samples are complex, and most of the pollutant components are low in content and have different forms. Therefore, before analysis and determination, pretreatment is often required to obtain the form and concentration of the components to be measured that are suitable for the requirements of the determination method. And the sample system that eliminates the interference of coexisting components. During the pretreatment process, the content of the components to be measured is often changed due to volatilization, adsorption, pollution and other reasons. [0003] As people pay more and more attention to the environment, people's demand for environmental monitoring is also increasing. Since water samples are...

Problems solved by technology

[0003] As people pay more and more attention to the environment, people's demand for environmental monitoring is also increasing. Since water samples are often collected in areas far away from urban areas, there is a lack of testing and experimental equipment, and water samples need to be transported back to the city before they can be monitored.
