As is well known, the key to the high deodorization performance is the biotrickling filter, which is by nature the organic combination of the various biotrickling filter systems as a new kind of means in deodorizing processing. The technology is so special that it has introduced into itself the deodorizing system of biotrickling filter. Notion has also to be done of the biotrickling filter system that has been affected by the biological stuffing, the operating parameters as well as the degradation bacteria. It is also for the purpose of identification and clarification of the structure and the function of the system that we have mainly analyzed the development of the biological stuffing and compared the physicochemical characteristics and the deodorization functions in dealing with all the different packed materials. We have also made a theoretical and practical summary of the processing parameters, such as the inlet concentration, the residence time, the spray flow rate and the pH of percolate in this paper. Another important factor that affects the quality and function of the deodorization is the degradation bacteria to be used in the process, which helps to make full use of the odor pollutants for metabolic and then convert them into carbon dioxide or energy sources. Our review also goes on with further briefing of the species and functions of the degrading bacteria and illustration of their detailed applications in the biotrickling filter deodorization, with a general review of the mass transfer degradation regulations of the stench components on the packed materials. In addition, the paper has done an analysis of the different operating conditions that may affect the mass transfer resistance qualitatively in the gas film and liquid film on the basis of the mass transfer model. Theoretically speaking, we have also depicted the degradation reaction
