The invention discloses an intelligent control method for an A2O biological tank process. The method comprises the following steps: setting input parameters required by modeling; establishing an ASM2D model of the A2O biological tank; establishing an ASM3 mathematical model of the secondary sedimentation tank; establishing a sedimentation process mathematical model of the secondary sedimentation tank; the models are compiled by adopting a C language and are converted into S functions which can be called by software and are used for simulating an A2O process; performing steady-state simulation on the models, correcting parameters of each model, and simulating and adjusting the effluent quality; performing deep learning adaptive control and adaptive correction are carried out, and screening target control parameters; outputting optimal control parameters after model simulation; and outputting the optimal control parameters to a PLC control platform to control the process. Technical guidance can be provided for transformation and optimization of an intelligent control system of a sewage treatment plant, higher sewage treatment efficiency is achieved, the operation energy consumption of the sewage treatment plant is reduced, and the operation cost is saved.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a 2 O biological pool process intelligent control method. Background technique [0002] At present, in the sewage treatment industry, the intelligent water affairs developed by scientific and technological means, mature technology and exposed problems make the optimal control technology in the sewage treatment process an urgent problem to be solved. The water treatment process derived from the activated sludge method is mature and stable, and the treatment effect is good; however, it still adopts empirical or semi-empirical methods in terms of process design and operation and maintenance. Therefore, at present, most sewage treatment plants lack scientific management and control in terms of design and operation and maintenance, resulting in an increase in investment and operation costs. [0003] A 2 O (Anaerobic-Anoxic-Oxic) process, that is, anaerobic-anoxic-aerobic p...
