A rapid detection method for dewatering performance of anaerobic digestion

ActiveCN120847015Bshort sampling timesmall doseFt ir spectraPeak fitting
The application provides a kind of anaerobic digestion residue dewatering performance rapid detection method, belong to the technical field of biomass waste dewatering performance detection.Specifically: collect anaerobic digestion in 400-4000cm ‑1 Wavelength range of full-band infrared spectrum data;Using infrared spectrum analysis software to obtain the infrared spectrum data is smoothed;According to the data obtained, select 1550-1750cm ‑1 Wavelength range of infrared water spectrum data related to O-H bending vibration, Gaussian deconvolution and peak fitting are carried out using peak fitting software, and are decomposed into six sub-peaks, p1-p6;And calculate the area ratio of each sub-peak, and the ratio of the area ratio of sub-peak 1-2 and sub-peak 3-6 is represented by the sum of the area ratio of sub-peak 1-2 and sub-peak 3-6, and the value is higher, which means it is more difficult to dewater.The infrared detection method of the application has the advantages of clean, efficient, low dose, low cost, batch detection, etc.

Sampling device and sampling method

ActiveCN121475762Bachieve wide coverageRefined positioning capabilitiesWithdrawing sample devicesStands/trestlesWorking environmentControl theory
The application provides a sampling device and a sampling method, relates to the technical field of mining material sampling, and aims to solve the problems of blind coverage, human error, low efficiency, high labor intensity, and poor working environment in the traditional manual sampling mode to some extent. The sampling device provided by the application comprises a stand, a first cantilever, a second cantilever, a mast and a spiral sampling mechanism. The first end of the first cantilever is rotatably connected to the top of the stand. The first end of the second cantilever is rotatably connected to the second end of the first cantilever. The top of the mast is connected to the second end of the second cantilever. The mast comprises a lifting mechanism. The spiral sampling mechanism is connected to the mast through the lifting mechanism and can be lifted along the mast through the lifting mechanism. The spiral sampling mechanism comprises a sampling drive, a spiral sampling head and a sampling assembly. The output end of the sampling drive is connected to the spiral sampling head. The sampling assembly is used for collecting the material collected by the spiral sampling head.
