超滤-膜接触臭氧氧化技术处理印染废水
Ultrafiltration-ozone membrane contactor for textile wastewater treatment
摘要
Abstract
In this study,an ultrafiltration-ozone membrane contactor was applied to secondary effluent from textile wastewater treatment.Operational parameters were optimized and treatment efficiency was studied.The optimized parameters for the molecular weight cut-off of the ultrafiltration membrane,membrane length of the membrane contactor,ozone concentration,gas flow rate,and water flux were 100 kDa,2 m,10 mg · L-1,0.6 L ·min-1,and 1.4 L · h-1,respectively.After eight days,the average COD decreased from 131 mg · L-1 to 70 mg · L-1,average color decreased from 130 to 20,average turbidity decreased from 11 NTU to 2.3 NTU,and B/C value increased from 0.167 to 0.244.关键词
