The automatic flipping oscillator is a fully automatic working mode, which consists of three parts: extraction bottle and frequency-adjustable motor and control system
.
Its working principle is to make the extractant rotate back and forth in the extraction bottle from top to bottom, and then from bottom to top through the adjustable frequency motor, so that the extractant and the water sample are fully combined and violently collided, and the rotation is oscillated to achieve the purpose of complete extraction.
At the same time, the whole extraction is completed in a closed extraction bottle, which completely solves the problem of reagent volatilization, makes the extraction result more stable and reliable, and the extraction data is authentic and credible
.
In the process of stacking or disposal, solid waste containing harmful substances will be leached by water, which will cause the migration and transformation of harmful substances and pollute the environment
.
Leaching experiments are field or laboratory simulations of this natural process
.
When the amount of leached harmful substances exceeds the threshold set forth in relevant regulations, the waste has leaching toxicity
.
The identification of leaching toxicity of solid waste is the basis for the determination of hazardous waste, and it is also an important technical link in the development of solid waste management and disposal technology
