Description

technical field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an intelligent urban sewage treatment device based on biological control. Background technique

[0002] Activated sludge method is the most widely used biological control sewage treatment method in urban sewage treatment plants, which has the advantages of economy and good treatment effect. Activated sludge is mainly composed of microorganisms that can absorb and degrade organic matter in sewage and pollutants such as nitrogen and phosphorus; during the treatment process, activated sludge is mixed with sewage and is in a suspended state, and the treated mud-water mixture enters the secondary sedimentation process. Separation of mud and water is realized in the pool to prevent the loss of activated sludge with the effluent, and achieve the purpose of recycling activated sludge while discharging clean water.

[0003] However, in the actual process of sewage tr...
