【Abstract】 It is of profound instructive significance for the design and function of the aerobic reactor to study the dynamics of nitrosation due to the fact that the combined process of nitrosation and the aerobic ammonium oxidizing is used to treat coking wastewater.Based on the different generation periods between the nitococcus and nitrobacteria,Lawrence-McCarty model is utilized to study the dynamics of coking wastewater,and a series of parameters are obtained,v_max=2.03 mgNH₄⁺-N·mgVSS^-1·d^-1,K_s=22.07 mgNH₄⁺-(N·L^-1,)Y=0.257 4 mgVSS·mgNH₄⁺-N^-1,K_d=0.086 4d^-1.The relationship between the biomass concentration and sludge age of an aeration basin in the dynamics model are discussed.A series of experimentation datum prove that there is a correlating equation between them.更多还原
