Claim 1:
2. The method of claim 1, wherein in S2 operations for selecting collaborative optimization parameters comprise:
S2-1: setting process parameter values: determining set values of carbon/nitrogen ratio, pH and dissolved oxygen;
S2-2: model selection: selecting the ASM mDON DIN model 1 or 2 according to a numerical value of the carbon/nitrogen ratio in S2-1;
S2-3: collaborative optimization: based on the model selected in S2-2, obtaining a minimum value of a sum of a concentration of organic nitrogen and a concentration of inorganic nitrogen in the effluent and corresponding process operation parameters by using the process parameter values set in S2-1 as a design factor of a response surface methodology and the sum of the concentration of organic nitrogen and the concentration of inorganic nitrogen in the effluent as a response value; and
S2-4: outputting best parameter values: outputting the minimum value of the sum of the concentration of inorganic nitrogen and the concentration of organic nitrogen in the effluent and the corresponding process operation parameters comprising the carbon/nitrogen ratio, pH and dissolved oxygen, obtained in S2-3.
