| 中文摘要 |
| 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4.86 kg/(m3·d)、苯酚容积负荷可达1.96 kg/(m3·d)，出水COD低于200 mg/L、出水苯酚浓度低于1 mg/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2.04 kg/(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800 mg/L时，最佳水力停留时间为9～10 h.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/(m3·d ) and 1.96 kg/(m3·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·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. |
