Outlet water TN predictive control method based on predictive control process optimization

The invention provides an outlet water TN predictive control method based on predictive control process optimization. Comprising the following steps: setting a process core parameter on-line monitoring instrument, determining the effluent dissolvability TN control concentration of the biological treatment system, predicting and contrastively analyzing the effluent dissolvability TN concentration of the biological treatment system in real time, and classifying and adopting a process regulation and control technical method by combining real-time prediction and analysis results. According to the invention, on the basis of online monitoring of ammonia nitrogen and nitrate nitrogen at the water outlet end of the post-anoxic tank, real-time prediction of the effluent dissolvability TN concentration and shortening and optimization of a TN prediction control process are carried out; the method can solve a series of problems that an existing town sewage treatment plant effluent TN prediction control method has many in
