Advanced treatment of dying and printing wastewater using microflocculation direct filtration-UF combination process
微絮凝直接过滤-超滤组合工艺深度处理印染废水

Microflocculation direct filtration as the pretreament process of ultrafiltration was used for the advanced treament of secondary effluent of dyeing wastewater.The treatment efficiency and different pretreatment methods such as microflocculation,sand filtration and microflocculation direct filtration on the impact of ultrafiltration membrane fouling were investigated.The experimental results show that the removal rates of turbidity,color and COD are 99.2%,87% and 56%,respectively.The effluent quality of the...
