摘　　要：通过连续动态试验,对新型微压流化式复合生物反应器(MP-FHBR)处理模拟苯酚废水的效能进行研究.结果表明,MP-FHBR的COD容积负荷可达4.86kg/(m3·d)、苯酚容积负荷可达1.96kg/(m3·d),出水COD低于200mg/L、出水苯酚浓度低于1mg/L,COD和苯酚去除率分别达到90%和99%以上.当苯酚容积负荷达到2.04kg/(m3·d),苯酚在反应器中逐渐累积,反应器内微生物的TTC-比脱氢酶活性下降.当MP-FHBR进水苯酚浓度为800mg/L时,最佳水力停留时间为9～10h.水力负荷对反应器沉淀池的泥水分离效果影响较大,限制了反应器的进水量,所以MP-FHBR主要适用于处理较高浓度的含酚废水.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 /（m^3·d） and 1.96 kg/（m^3·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 /（m^3·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.
