Description

technical field

[0001] The invention belongs to the field of sewage treatment, and relates to a sewage treatment system, in particular to an improved sewage treatment system. Background technique

[0002] At present, the domestic municipal sewage treatment process basically adopts traditional methods, using physical and chemical means to degrade and purify. After reaching the relevant national standards, it is used as reclaimed water for secondary use or directly discharged into rivers. The treated water enters the river, and the residual organic matter or other components need to be naturally degraded to achieve the purpose of harmlessness. However, the total amount of sewage is large, the discharge cycle is short, and natural degradation is difficult to digest the increasingly accumulated components to be degraded in a short period of time, which will still have a negative impact on the natural environment. Contents of the invention
