Model method for describing quantitative relation between oxygen mass transfer rate coefficient and aeration rate

The invention discloses a model method for describing a quantitative relationship between an oxygen mass transfer rate coefficient and an aeration rate, which comprises the following steps of: measuring oxygen mass transfer rate coefficient KLA values under different aeration rates by using a dynamic method, and establishing a quantitative relationship model equation between the oxygen mass transfer rate coefficient and the aeration rate on the basis of gas disturbance and a specific surface area theory; and fitting the quantitative relation model equation between the oxygen mass transfer rate coefficient and the aeration rate with KLA values actually measured by different aeration rates, determining each parameter value, and obtaining a quantitative relation model between the oxygen mass transfer rate coefficient and the aeration rate. According to the model method for describing the quantitative relation between the oxygen mass transfer rate coefficient and the aeration rate, the relation between the oxygen
