Abstract: The research on the pilot scale advanced treatment has been accomplished for the wastewater after secondary treatment by laminated filter+UF+RO system in a paper mill. The results show that when its average COD is 4.44 mg/L,and SS less than 1 mg/L,the removing rates of COD and SS are 96.1% and 97.9% respectively,condu-ctivity 19.39 μS/cm,average desalination rate as high as 99.5%,and average turbidity dropped to 0.06 NTU, excellent effluent can be obtained. In general,the water treated by this technology can completely meet the requirements of the recycled water quality standards. This process has the advantages of continuous and stable operation,and feasible and reliable techniques.
