Characterization of Pollutants for Polymer Wastewater by Membrane

摘要

Polyrner is the essential material of computer equipment ,however so far polymer wastewater is bard to treat in the world.ln this paper the state of wastewater treatment was investigated in polymer factory and a new analysis method was used to study the characterization of the pollutants for polyner wastewater by membrane. The CODcr of polymer wastewater is complicated, involving colloid (1-5nm) (58.59% CODcr), < O.1μm portions (21.41% CODcr), and no more than 200 molecular weight substance (20% CODcr). The ammonia-nitrogen mainly is the small molecular (88.30%),which can be removed by UF and RO membrane.S032- is the same as the ammonia-mtrogen, and the S032- of the polymer tower effluent is 122.57 mg/L ,which respectively could be cut off almost half by UF and RO membrane. Then treatment technology is recommended by these analysis data. So membrane gradient separation, as an useful tool for better interpretation of wastewater, is apparently vital for water quality analysis and engineering project design.
