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.

The utility model discloses a sampler for environment-friendly detection of waste water, which comprises a box body, a suction tube is arranged below the box body, and a suction head is arranged at the bottom of the suction tube; a double-shaft motor is arranged in the box body, the first output end of the double-shaft motor is connected with a moving assembly, suction operation is facilitated through the moving assembly, the side end of a suction cylinder is connected with a storage assembly, storage is facilitated, and the inconvenience problem that sucked waste water needs to be secondarily conveyed is solved; and a clamping assembly is mounted on the storage assembly, so that the storage assembly can be conveniently clamped and used. According to the sampler for wastewater environment-friendly detection, wastewater is conveyed into the storage cylinder through cooperation of the hose and the connector, the problem of inconvenience caused by secondary conveying of the sucked wastewater is solved, the sampling efficiency is greatly improved, the wastewater in the storage cylinder is rapidly detected, and the sampling efficiency is improved. The problem that the detection accuracy is reduced due to the fact that the wastewater sample needs to be stored for a long time is solved.

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.

The invention provides a needle tube sampling method. The needle tube sampling method comprises the following steps: S1, communicating a first pipeline with a sampling needle and an oil discharge port; a second pipeline is communicated with the first pipeline and the waste oil tank, and a first switch valve is used for controlling on-off of the second pipeline; s2, an oil discharge outlet is opened, oil in to-be-detected equipment enters the sampling needle tube, after the oil entering the sampling needle tube reaches a preset volume, the oil discharge outlet stops discharging oil, a first switch valve is opened, a piston rod of the sampling needle tube is reversely pushed until the piston rod reaches a zero position, one-time cleaning is completed, and the cleaning steps are repeated until preset cleaning times are completed; s3, oil is discharged through an oil discharge port, oil in the to-be-detected equipment enters the cleaned sampling needle tube, after the oil entering the sampling needle tube reaches the preset volume, oil discharge is stopped through the oil discharge port, and sampling is completed. Compared with a conventional sampling mode, the sampling mode provided by the invention has the advantages that the insulating oil is not in contact with external air in the whole process, the final detection accuracy is ensured, and the waste is less.
