title: [Efficiency of micro-pressurized fluidized hybrid biological reactor for treating phenolic wastwater].
abstract: A dynamic experiment was conducted continuously to study the efficiency of the new micro-pressurized fluidized hybrid biological reactor (MP-FHBR) for treating artificial phenolic wastewater. The experimental results showed that the COD volumetric loading and phenolic volumetric loading of MP-FHBR could reach 4.86 kg/(m3 x d) and 1.96 kg/(m3 x d) respectively; effluent COD was lower than 200 mg/L; phenol concentrations of effluent were lower than 1 mg/L; removal rates of COD and phenol reached 90% and 99% above respectively. When volumetric loading of phenol in MP-FHBR reached 2.04 kg/(m3 x d), phenol will accumulate gradually in the reactor along with the reactor running, and specific TTC-dehydrogenase activity of microbe in the reactor declines. When phenol concentration of influent was 800 mg/L, the optimum HRT was 9-10 h. Because of the influence of hydraulic loading on the settling performance of sedimentation tank of the reactor, MP-FHBR was superior to treating higher-concentration phenolic wastewater.
