Distillation-Iron and Carbon Micro-Electrolysis-A/O Biochemical Process for Treatment of High Concentration Organic Polyester Wastewater

Distillation-iron and carbon micro-electrolysis-A/O biochemical process was adopted to treat high concentration organic polyester wastewater. The result of the treatment shows that a large amount of organic compound was separated, CODcr of the outflow was about 10, 000 mg/L in average and the removal rate reached over 90% after treatment by distillation and iron and carbon micro-electrolysis. And after A/O biochemical treatment, the outflow was achromous, clear and translucent and free of peculiar smell, the removal rate of organic compound reached above 90% and CODcr of the outflow was about 19.6 mg/L, which is significantly lower than the national discharge standard of 100mg/L.
