Abstract

Abstract

The treatment of power plant sewage based on the Suspended Biofilm Bed Reactor (SBBR)-filtra tion-ozone mixed process was studied. The system can endure various organic load impact and hydraulic load impact. The best removal rate of COD_cr reached 95% and the mass concentration ranged in 10-30 mg/L. The removal rate of phosphorus was over 50% and the mass concentration lower than 0.5 mg/L. The removal rate of NH₃-N was over 80%. The removal rate of turbidity reached 84%, more than 99.9% of bacteria had been killed and the bacteria concentration was 1/L.
