Summary:The invention discloses a sewage treatment aeration system control method based on microbial communities, and belongs to the field of wastewater treatment. The method comprises the following steps: firstly, constructing a long short-term memory (LSTM) network model on the basis of sludge concentration, sludge volume index, dissolved oxygen concentration and active sludge microflora structure data; training the model by adopting sludge concentration, sludge volume index, dissolved oxygen concentration and activated sludge microflora structure data obtained under the conditions that a sewage treatment system normally runs and the sludge performance is good, and then calculating the optimal aeration rate in an application state by adopting the trained model and performing aeration control. The dissolved oxygen regulation and control method provided by the invention can effectively reduce the abundance of microorganisms causing poor sludge performance (sludge bulking or foaming) in a sewage treatment system, so t
