Hydrogen,as an ideal clean energy source,possesses remarkable characteristics such as excellent energy production efficiency,environmental friendliness,and sustainability.However,the insufficient production of hydrogen constrains its primary development in industrial application,thus necessitating the development of economically efficient hydrogen production technology.Utilizing the discarded activated sludge for anaerobic fermentation-based hydrogen production,is with a simpler operation and lower energy consumption,and it can also utilize a wide range of organic waste materials as substrates,demonstrating significant developmental potential.Within the anaerobic fermentation process of sludge for hydrogen production,process models exhibit capabilities including data analysis and prediction,parameter and operational strategy optimization,system and design optimization,as well as multi-factor analysis and system modeling.Through the construction of process models,a better understanding and guidance of the sludge hydrogen production process can be achieved,enabling efficient,stable,and sustainable anaerobic fermentation-based hydrogen production technology.However,different anaerobic fermentation process models have their own advantages and limitations,so it is necessary to summarize the progress of process model research,so as to select the appropriate model for fermentation process optimization and prediction according to the actual situation,and obtain more accurate simulation results and expand the scope of application.Based on this,this paper comprehensively analyzed the latest process progress of hydrogen production by anaerobic fermentation of waste activated sludge,as well as the application status and limitations of anaerobic fermentation process modeling in prediction and optimization.This is helpful to promote the application of sludge anaerobic fermentation for hydrogen production,and realize the sustainable utilization of sludge resources more effectively.
