The spray painting wastewater mainly comes from the air in the working area of the wet spray painting room by washing the spray painting room with water, and the paint and organic solvent in the air are transferred to the water to form the spray painting wastewater. The wastewater contains a large number of paint particles, and its water quality is determined by the coatings used (mainly nitro paint, amino paint, alkyd paint and epoxy paint), solvents (such as ethanol, acetone, esters, benzene) and additives. Spray paint wastewater is generally complex in composition, high in concentration and poor in biodegradability.
