Process for treating waste water Acrylic

The present invention discloses a process for treatment of waste acrylic fiber, acrylic fiber after pretreatment of wastewater, waste organic salt to obtain a low and very low concentrations of organic-containing high salt concentration water separated by the second set of electrodialysis; containing the salts of organic wastewater to improve low oxidation treatment by advanced biodegradable, and then through the a / O standard biological treatment, the low concentration of organic matter-containing high salt concentration water, and then subjected to reverse osmosis desalination reverse osmosis and concentrated to give pure water, pure water back on production, the second set of water through the reverse osmosis concentrate was concentrated electrodialysis water production; process of the present invention to provide biological treatment and advanced oxidation technology, utilization of membrane separation technology is more fully and effectively achieve degradation of recalcitrant organics and hard natural sedimentation of the organic polymer, the degradation of wastewater recycling, water can be obtained back on production, the real resource processing.
