Treatment method for vehicle body spraying water-based hazardous waste solution

The invention provides a treatment method of a vehicle body spraying water-based hazardous waste solution, which comprises the following steps: step 1, collecting a vehicle body spraying water-based waste solvent, and concentrating in a wastewater treatment tank for dilution; step 2, putting the diluted vehicle body spraying water-based waste solvent into a reactor, adding a preset amount of a viscosity breaking agent and a coagulant by using a charging pump, and stirring to fully generate a chemical reaction, so that solid waste residues are generated in the vehicle body spraying water-based waste solvent; 3, the mixture obtained after the sufficient chemical reaction is put into a clear water separation area, and solid waste residues are separated from clear water; 4, the solid waste residues are collected, concentrated centrifugal dewatering is conducted, and finally the solid waste residues are placed in a waste residue collecting bag; and step 5, conveying the separated liquid into the wastewater treatme
