Description

technical field [0001] The invention relates to an artificial intelligence control system and method for reducing foam in coal-gas industrial wastewater, belonging to the technical field of industrial wastewater treatment. Background technique [0002] Foam pollution often occurs in the process of coal-to-gas industrial wastewater treatment, which is generally divided into two categories: chemical foam pollution and biological foam pollution. Chemical foam is caused by foaming substances (such as surfactants, certain suspended substances, etc.) in wastewater under aeration or stirring conditions. Biofoam is a stable three-phase system formed by air-water-microorganisms. The direct reason is that due to the large number of filamentous bacteria (mainly Nocardia and Microthrix), the filamentous bacteria are basically filamentous or Branch-shaped, it is easy to catch suspended particles and air bubbles to float to the water surface, forming a relatively stable biological foam. ...
