Recycling treatment method of nitrocotton wastewater

The invention belongs to the field of wastewater treatment, particularly discloses a nitrocotton wastewater recovery treatment method, and aims at solving the problems that an existing nitrocotton wastewater recovery treatment mode is low in nitrocotton recovery efficiency, and recycled water obtained after treatment is poor in water quality. According to the recycling treatment method, the disc filter is adopted to replace a sedimentation tank in the nitrocotton wastewater treatment system to filter the nitrocotton wastewater, so that the filtering efficiency of the nitrocotton wastewater can be improved, the loss of nitrocotton in the recycling treatment process is reduced, and the water quality of recycled water is improved; meanwhile, the disc filter is backwashed when the filtering efficiency of the disc filter is reduced by one level, so that the filtering effect of the disc filter can be ensured, the water quality of recycled water is ensured, the wastewater treatment cost is further reduced, and the q
