The utility model relates to the technical field of production of viscose staple fibers and in particular relates to a system for recycling rinsing trough CS2. The system comprises secondary drafting systems, third drafting systems and at least two rinsing troughs, wherein spray water outlets of the secondary drafting systems and the third drafting systems are communicated with a first CS2 recycling trough through pipelines; overflow water outlets of the rinsing troughs are communicated with the first CS2 recycling trough through pipelines; and the first CS2 recycling trough is connected with a second CS2 recycling trough. By utilizing the system, waste caused by the fact that CS2 and water resource in the existing overflow water are not recycled sufficiently is reduced, the production cost is saved, and pressure for environmental protection is reduced. A large amount of CS2 is not discharged to an alkali ditch so that potential risk is avoided, CS2 is recycled, acidic water is recycled, and resource is saved.
