NOVELTY - Treating antibiotic wastewater comprises adding polymeric aluminum (180-200 mg/L) to the antibiotic wastewater to carry out coagulation pre-treatment; adding glucose (1200-1600 mg/L); and treating the wastewater in upflow anaerobic sludge blanket-aerobic membrane bioreactor (UASB-MBR) combined device, controlling hydraulic retention time of the system at 20-22 hours, controlling hydraulic retention time in the anaerobic sludge blanket-aerobic membrane bioreactor at 12-14 hours, and controlling hydraulic retention time in the aerobic membrane bioreactor at 7-9 hours.    USE - Method for treating antibiotic wastewater (claimed).    ADVANTAGE - The average COD removing rate is 86.56%, and the suspended solid in the mixed liquid (MLSS) is 3000-4000 mg/l. The effective removing rate of the combined device is 80-85%. The COD of the treated water meets the wastewater emission standard of national biopharmaceutical industry (GB8978-1996), where the emission standard is 300 mg/l.    DETAILED DESCRIPTION - Treating antibiotic wastewater comprises:    (A) adding polymeric aluminum (180-200 mg/L) to the antibiotic wastewater to carry out coagulation pre-treatment, and then regulating the pH to 7.0, where the sedimentation time of coagulation pre-treatment is 2.5-4 hours, and the chemical oxygen demand (COD) concentration and turbidity of the treated wastewater are all reduced to some degrees;    (B) adding glucose (1200-1600 mg/L) to the wastewater to reduce the growth and reproduction of strain and improve the operation property of the treating system;    (C) treating the wastewater in UASB-MBR combined device, controlling the hydraulic retention time of the system at 20-22 hours, controlling the hydraulic retention time in the anaerobic sludge blanket-aerobic membrane bioreactor at 12-14 hours, and controlling the hydraulic retention time in the aerobic membrane bioreactor at 7-9 hours, where the average COD removing rate of the wastewater is 86.56%.    An INDEPENDENT CLAIM is included for UASB-MBR combined device, comprising an UASB (1), MBR (2), a circulating pump (3), a heater, soft fiber filling, a hollow fiber film subassembly (6), an aeration head air-source air pump and a three-phase separator (8). The soft fiber filling in the UASB is filled with particle sludge containing various strains. The bacterial forms particle aggregate helpful to the physiology and biochemistry condition of the growth of bacterial and helpful to the degradation of organics. The particle size of the anaerobic microbe particle sludge in the sludge blanket is 0.5-5.0 mm, and the density is 1025-1080 kg/m3. The hollow fiber film subassembly in the MBR is the film with small fiber pores, which is helpful to the interception of organic macromolecular materials and helpful to remove the bacteria and virus by filtering with film.
