摘　　要：金东纸业超滤(UF)和反渗透(RO)污水处理回用系统在运行约四年后,由于反渗透进水水质存在波动,碱度、电导率和硬度常常偏高,导致反渗透系统非常容易结垢和污堵。采用综合膜处理方案,结合应用3D TRASAR膜自动化技术后,污水回用系统总运行费用(TCO)明显下降,减少了清水用量,从根本上消除了系统运行的隐患。After four years operation of the water recycling system with ultra filtration and reverse osmosis in Gold East Paper,scale formation and dirt blockage occurred in reverse osmosis because of higher alkalinity,conductivity and water hardness.The composite membrane treatment project was adopted to reduce the running cost and fresh water consumption,eliminate the hidden danger.
