[0001] The utility model relates to the field of sewage purification, in particular to sewage purification equipment. Background Art

[0002] Paint spraying wastewater is a special type of industrial wastewater, which mainly comes from the pre-paint surface treatment and painting process during the painting process. This wastewater contains a variety of complex components, such as emulsified oil, surfactants, etc. Since paint spraying wastewater contains a large amount of harmful substances, direct discharge will seriously damage the ecological balance.
