Description

technical field

[0001] The invention relates to the field of industrial wastewater treatment devices, in particular to an air-assisted oil film dispersion extraction device and a method thereof applied to industrial wastewater. Background technique

[0002] At present, the industrial wastewater treatment devices on the market have poor separation effect on the waste water and the oil in the wastewater, which makes it difficult to affect the next step of industrial wastewater treatment. In addition, most industrial wastewater treatment devices, due to their own conditions and process limitations, make industrial wastewater The treatment device does not completely separate water and grease, so multiple treatments are required to separate water and grease, which increases the treatment cost of industrial wastewater. Industrial wastewater treatment devices on the market do not treat the initially separated grease, thus There are cases where oil purification treatment is difficul...
