| Abstract: | Anaerobic digestion, as a biodegradation and biogas production technology, has become one of the effective ways to solve the problem of non-point source pollution of agricultural wastes. Its fermentation process is a complex biotransformation process, so process monitoring is particularly important. This paper systematically reviewed the development of anaerobic digestion on-line monitoring technology at home and abroad, and put forward the scientific and technical problems needed further study. The analysis showed that the current control system for anaerobic digestion process was mainly based on embedded microcontrollers unit(MCU) monitoring system, programmable logic controller(PLC) monitoring system and monitoring system based on industrial personal computer(IPC). Sensors collecting data for control systems in real time included:electrochemical sensors, spectroscopy sensors, chromatographic sensors and so on. Based on the current research, this paper put forward:(1) According to the characteristics of anaerobic digestion and biogas production process, a more accurate, stable and wide range of on-line monitoring system was the core problem in this field.(2) Future research should be focus on monitoring parameters of material characteristics, improving biogas production and anaerobic digestion efficiency. |
