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 require-ments of the recycled water quality standards. This process has the advantages of continuous and stable operation , and feasible and reliable techniques.
