The treatment process combining multi-medium filter-UF-RO has been applied to the pilot research on the advanced recycling treatment of anaerobic-aerobic-coagulation air flotation effluent in a biological agent plant. The experimental results show that under the condition of influent water quality being tested ,it is ensured that the system can be operated stably with the PVDF external pressure ultrafiltration membrane and dow antipollution RO membrane. The SDI of ultrafiltration system yielding water is less than 3 ,and RO desalination rate 97.5%. All of the yielding water indexes can meet the requirements for water quality of cooling tower make-up water. The designed daily water yield of the project is 600 m3,investment needed CNY3,000,000.00,cost-saving CNY1,280,000.00 per year,and the period of investment return 2.34 a.
