The invention relates to an on-line monitoring device for anaerobic digestion process, characterized in that the on-line monitoring device includes an anti-corrosion mechanism, a first fixing device, a second fixing device, a reflective plate, a first light-transmitting sheet, a second A light-transmitting sheet and a near-infrared spectrometer; the anti-corrosion mechanism is composed of an upper anti-corrosion mechanism fixedly connected to a lower anti-corrosion mechanism, and a passage for the circulation of the fermentation liquid is arranged between the upper anti-corrosion mechanism and the lower anti-corrosion mechanism; The first fixing device is inserted and fixed in the center of the upper anti-corrosion mechanism, and the second fixing device is inserted and fixed in the center of the lower anti-corrosion mechanism; A light-transmitting sheet, the near-infrared spectrometer is arranged in the second fixing device, and the second light-transmitting sheet is arranged above the near-infrared spectrometer. The present invention can be widely used in the technical field of biochemical reactions.
Description
technical field [0001] The invention relates to an on-line monitoring device for anaerobic digestion process, and belongs to the technical field of biochemical reaction. Background technique [0002] As a method of biodegradation and biogas production, anaerobic digestion has become one of the effective ways to solve the non-point source pollution of agricultural waste and provide clean and green energy. Due to the strong complexity, time-varying, nonlinear and uncertainties of the anaerobic digestion reaction process, the online monitoring of the fermentation process is particularly important. At present, the means of monitoring the anaerobic digestion process are generally based on the experience of the staff (in engineering), or through the routine chemical analysis methods in the laboratory. However, due to problems such as strong subjectivity, large individual differences, lack of detailed data, and inconvenient establishment of databases in empirical operations, and l...
