Abstract

Abstract

Volatile organic compounds （VOCs） are a significant class of pollutants in the atmosphere. Biological technology is widely used in treating VOCs with large air flow rates and low concentrations， because of the advantages of mild reaction conditions， low economic cost， and minimal secondary pollution. Proper reactor modeling can effectively simulate reactor operation， chemical reactions， and substance transport processes. The early models were mainly used to simulate the biofilm dynamics of gas flow， phase transfer， biodegradation， and biological growth. The methods used to establish the models were relatively standard， generally accepted， and widely used in industry. In recent years， with the development of fluid mechanics， mathematics， and computer science， new models can simulate more complex processes while ensuring the repeatability and stability. In this paper， the research progress of bioreactor models for VOCs was reviewed， focusing on the classical biofilm dynamics model， the computational fluid dynamics（CFD） model for bioreactors， and the artificial neural network（ANN） model. The basic principles， important parameters， application conditions and research status of various models were expounded. The shortcomings and future development trends of bioreactor models were also analyzed， providing a scientific basis for revealing the VOC biodegradation process and improving the design and practical application of biological treatment systems. In the future， more attention should be paid to improving the combination of artificial neural network model and the CFD model to improve its operability and universality.
