Abstract—The token of size distribution of pollutants and the particle effects on the pollution controlling attract much attentions recently. After investigation to the main technology in FUSHUN factory and the running state of wastewater plant , two key sources of wastewater were as the key objects. The COD of polymer wastewater is complicated, involving colloid (1-5nm) (accounting for 58.59% COD), particles ﹤ 0.1μm portions (accounting for 21.41% COD), and substances of no more than 200 molecular weight (accounting for 20% COD). The ammonia-nitrogen mainly is the small molecular (accounting for 88.30%), which can be removed by UF and RO membrane. SO3 2- is same as the ammonia-nitrogen, and SO3 2- of the polymer tower effluent is 122.57 mg/L. As to the solvent recovery effluents, the PSD based COD of the more than 0.1μm portion, colloid, nanometer grade and soluble COD fractions account for 1/4 . The ammonia-nitrogen of effluents for the solvent recovery tower is irregular. The total cyanide contribution of particle size beyond 0.1μm accounted for 91％. Acrylonitrile, as small molecule ,could be absorbed by colloid particles(1-2 nm) and then cut off by NF grade. And DMF could be absorbed by colloid, and the remaining could be separated by RO.
