厌氧消化流场可视化技术研究进展
Research progress on the visualization of flow field of anaerobic digestion
摘要
Abstract
Anaerobic digestion is a sustainable technology for organic waste treatment and disposal,which can produce renewable energy biogas while degrading organic waste.It is an environmentally friendly treatment technology.However,the substrate in anaerobic digestion system has complex rheological characteristics,and its high viscosity and poor flowability hinder the stable operation of the reaction.Therefore,research on flow field characteristics of anaerobic digestion can contribute to the understanding in internal flow pattern of anaerobic digestion system and improve the operating results and process stability.The characteristics of the substrate in anaerobic digestion and applicable rheological models are analyzed,and current status of the rheological model selection in numerical computational fluid dynamics(CFD)simulation process as well as application of particle image velocimetry(PIV)and positron emission particle tracking(PEPT)techniques are summarized.To obtain reliable flow field visualization results,it is necessary to pay attention to other rheological properties such as viscoelasticity and thixotropy while considering the shear-thinning properties of anaerobic digestion matrices.In future research,multiple flow field visualization techniques should be used in combination to optimize the hydrodynamic properties of anaerobic digestion.关键词
