Sewage treatment: The purpose of sewage treatment is to meet the water quality requirements of drainage to a certain water body or reuse, and to purify the process.

Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical,
environmental protection, urban landscape, medical treatment, catering and other fields, and the daily life.

Sewage treatment is generally divided into:
(1) Industrial wastewater discharged without treatment;
