Zusammenfassung:A substrate liquid processing apparatus of the present invention includes a process-liquid supply unit selectively supplying a plurality of types of process-liquids to the substrate held by a substrate holding table, first and second guide cups which are disposed in this order from the top and are configured to respectively guide downward the process-liquid scattering from the rotating substrate while being held by the substrate holding table; and a position adjustment mechanism adjusting a positional relationship between the first and second guide cups and the substrate holding table. A first process-liquid recovery tank is provided at a lower area of the first and second guide cups and recovers the process-liquid guided by the first guide cup. A second process-liquid recovery tank is provided at the inner peripheral side of the first process-liquid recovery tank and recovers the process-liquid guided by the second guide cup.
