The invention discloses a sewage treatment system for spinning production. The sewage treatment system comprises a box, a water inlet pipe is mounted on the left side of the top end of the box, a collection box is mounted on the right side of the top end of the box, a cylinder is mounted on the right side of the box, a water outlet pipe is mounted at the bottom end of the front face of the box, arotating ring is arranged at the top end of the water outlet pipe, and the rotating ring is connected with the water outlet pipe through a vertical rod. According to the sewage treatment system for spinning production, dissolved drug water effectively flows into sewage in the box to purify the sewage so that the sewage can be used repeatedly, the situation that the sewage is drained at will, thusthe natural environment is affected, and the sewage cannot be used cyclically is avoided, meanwhile the serious effect of pollution to water sources by industrial sewage is reduced, the sewage and thedrug water are effectively mixed, the situation that mixing is not good so that the sewage cannot be well purified, and the spinning effect is affected is avoided, the spinning efficiency is improved, and the consequences of environmental pollution caused by draining of the sewage are reduced.
