Extended data

Sewage treatment: the process of purifying sewage to meet the requirements of water quality discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields, and it has also entered the daily life of ordinary people more and more.

Technological progress and changes in social structure have promoted this group-based decentralization scheme, which is contradictory in itself, only the contradiction and unity between the two, and put forward the inherent demand of the whole industry to realize regional integration.
