PROBLEM TO BE SOLVED: To provide a separation method and a separation apparatus of a paint waste liquid having a high capacity of solid-liquid separation and a stable processing capacity to load fluctuations.SOLUTION: The capacity of solid-liquid separation of a separation method and a separation apparatus 80 of a paint waste liquid is enhanced by installing a pretreatment unit 70 for agitating circulation water and air in advance at a front stage of a coagulant mixing and agitating unit 54 for aspirating a coagulant, circulation water and air and agitating at a high-speed. Solid-liquid separation of paint components is thus stably practiced even when some load fluctuations occur in the circulation water.SELECTED DRAWING: Figure 1 |
