Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to municipal sewage treatment and reuse equipment. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care and catering. It is also increasingly entering the daily lives of ordinary people. The continuous aggravation of water pollution has caused unprecedented attention to the wastewater treatment and recycling industry.
