Aerobic Bacteria

In the presence of oxygen, aerobic microbial technology is carried out by borrowing the action of aerobic bacteria. In the process of aerobic microbial technology treatment, the dissolved organic matter in the sewage penetrates the cell wall of the bacteria and is absorbed by the bacteria. Solid and colloidal organic matter is first attached to the outside of the bacteria cell, and the extracellular enzymes secreted by the bacteria are decomposed into soluble substances, and then penetrate deep into the cell.

Through the aerobic treatment of aerobic bacteria, part of the organic matter in the sewage is inorganized, and a part of the organic matter is synthesized into the cell material of the microbial aerobic bacteria.  When there is more organic matter in the sewage water (more than the microbial life needs), the synthetic part increases, and the total amount of aerobic bacteria increases rapidly; when the organic matter in the sewage is insufficient, some microorganisms will die due to starvation, and their corpses will be  It becomes the "food" of another part of microbial aerobic bacteria, and the total amount of microorganisms will be reduced.  Although the cell material of microbial aerobic bacteria is also an organic material, the microorganisms exist in the water in a suspended state. Relatively speaking, the individual is relatively large, and it is easier to agglomerate.  The organic matter and some inorganic oxidation products and bacterial excrement, etc.) are precipitated together in the sedimentation tank by physical coagulation.
