Advanced Treatment of Campus Sewage by MV/UV/O3 for Water Reclamation
Abstract The microwave/electrodeless ultraviolet/ozone (MV/UV/O3) system was designed to deeply treat the outflow from the membrane bioreactor (MBR) process to meet the requirements for campus water reclamation. The effects of microwave power and UV intensity were studied by using factor experiments to find the relatively optimum technical parameters for disinfection, decolorization and deodorization. As the power of microwave raised from 300 to 450 W, the efficiencies of disinfection, decolorization, and deodorization were significantly increased; however, continuously increasing the microwave power to 600 W, the increased trend of treatment efficiency would be largely retarded. Similarly, the treatment efficiency of MV/UV/O3 system fiercely increased with increasing the UV light intensity from 0.52 to 1.04 mW/cm2, and then slowly climbed when further increasing the UV light intensity to 1.56 mW/cm2. Therefore, 300 W of microwave power and 1.04 mW/cm2 of UV light intensity (2 lamps) are the optimal parameters. Overall, MV/UV/O3 is an effective process to guarantee the effluent quality to meet the requirements of reclaimed water for miscellaneous use in campus.
