| 摘要 | For the treatment of the mixed flue gas desulfurization wastewater with high salinity by the biological fluidized bed process, the optimum temperature was 25-35 ℃, and the optimum hydraulic retention time was 10 h. When the influent quality was stable, the average concentration of COD, NH4+-N and TN in the inlet water was 210, 11 and 16.3 mg/L, respectively, and their average concentration in the effluent was 54, 0.32 and 4.09 mg/L, respectively. The treatment effect was good. When the incoming water quality of flue gas desulfurization wastewater fluctuated greatly, the effluent quality was still relatively stable after being treated by the biological fluidized bed, indicating that the biological fluidized bed process had a good ability to resist the impact of water quality in the treatment of high-salinity flue gas desulfurization wastewater. At the same time, the biological fluidized bed process provides a reference for high-salinity wastewater that is difficult to be biologically treated. |
