Abstract
[ Objective] To discuss the effect of each factor on the treatment effect in the pilot study of MBR. [ Method] With the high-performance hollow fiber membrane developed by PVDF as the test material, the sewage was treated by the A/O-MBR technology. [ Result] DO played an important role on ammonia and COD concentrations, when aerobic pool DO ranged from 3. 6 -3.9 mg/L, the effluent ammonia concentration was low, while it exceeded 4.0 mg/L, the ammonia concentration showed an increasing trend; while when the DO was below 3. 5 mg/L, the effluent COD increased significantly. The effluent COD was influenced by temperature, when the waler lemperature was under 25 ℃, the effluent COD stabilized at lower concentrations and fluctuated between 15 and 20 mg/L; when the temperature was higher than 25 ℃, the effluent COD increased significantly. The MLSS of the aerobic pool maintained at 5 - 6 g/L or more, the effluent COD concentration changed little, if it was less than 5 g/L, the effluent COD increased rapidly. [ Conclusion] The best sewage treatment conditions by MBR were 3.5 -4.0 mg/L DO, 20 -25 ℃ temperature and 6 - 10 g/L in the aerobic tanker.关键词
