【Abstract】 Through analyzing and detecting the main indexes of pollution and bio\|film of the inflow\|water and outflow\|water in the productive 4th class biological rotating contactor,the dynamics of the decomposition reaction of the pollution indexes,such as BOD\-5,COD and volatile phenol in the biological rotating contactor system was conducted,and the decomposition reaction class and reaction speed of these indexes were determined.So as to seek for more convenient design calculation formula to reveal the factor of the purification reaction of the biological rotating contactor and the factor which can influence the reaction,according to the material balance and monod’s relation,the mathematical model of the biological rotating contactor was obtained,that is; A/Q(L\- n-1 -L n)=1/P+K\- s /PL\-n; the experimental data was used to calculate the dynamic parameters of each class of the biological rotaging contactor.It is suggested that the mathematical model and the dynamic parameters in this paper can be used in designing the biological rotating contactor for the wastewater treatment.更多还原
