Abstract

The invention discloses a method for correcting model parameters in a sewage disposal process. The method comprises the steps as follows: step S1, obtaining technology of the model, influent water quality data and effluent quality data through field research, and then establishing a Benchmark platform based on ASM1; step S2, adjusting values of the model parameters according to flexibility positive and negative attributes and magnitude of the model parameters till the static simulation error of the model parameters is within 15%; and step S3, adjusting the residual model parameters according to the step S2 till the dynamic simulation error of the residual model parameters is within 20%, so as to obtain a final correction model. According to the method for correcting model parameters in the sewage disposal process, disclosed by the invention, the mathematical modeling efficiency of sewage disposal can be improved through simple and manual adjustment of major parameters, so that the situation that the model parameters can be adjusted only on the traditional basis of artificial experience is changed; therefore, the method is of great significance for upgrading and rebuilding of sewage disposal plants.

Description

technical field [0001] The invention relates to the technical field of engineering information, in particular to a method for correcting model parameters of a sewage treatment process. Background technique [0002] With the development of the national economy and the country's emphasis on energy conservation and efficiency, the requirements for the operating efficiency of sewage treatment enterprises are getting higher and higher. It is becoming more and more important to establish an effective model to analyze the influencing factors and adjust the operating process parameters. The traditional mathematical modeling method of sewage treatment process fully considers the biochemical reaction process of sewage treatment, which is the mathematical description of its essential phenomenon, and many large-scale sewage simulation software are based on the traditional mathematical model modeling method. The mathematical model established by this method is convenient Its research is ...
