| Abstract: | Through the study of blowing operation conditions of diffused aeration system, a chain of simplifications and assumptions concerning the oxygen transfer rate in the fine bubble clean water aeration are made, on the basis of which the theoretical model concerning the oxygen transfer rate is established. The main influencing factors of areation tank operating conditions upon transfer rate under the certain conditions are analysed. The relationship between these factors and oxygen transfer rate is determined. Also, the physical meaning and the model application are eventually analysed. |
