PROBLEM TO BE SOLVED: To provide a surface treatment line which includes different surface treatment sections aligned, separates an upstream side section from a downstream side section without disturbance of movement of work-pieces or mixing of different chemicals and water used in individual sections and recovers the adhered chemicals and water separately without mixing. ! SOLUTION: In a surface treatment line, a freely openable/closable partition wall is provided between an upstream side section 4 and a downstream side section 5, and the partition wall consists of an upstream side curtain 1 facing the upstream side section 4, a downstream side curtain 2 facing the downstream side section 5, a raising/lowering body 3 raising and lowering integrally the upper edges of the upstream side curtain 1 and the downstream curtain 2, an upstream side storage frame 46 surrounding the lower edge of the upstream side curtain 1 and a downstream side storage frame 56 surrounding the lower edge of the downstream curtain |
