摘　　要：为了达到高效、低能耗处理分散性生活污水的目的,研制了无污泥回流和无沉淀池的流化床-固定床一体化反应器。使用该反应器对模拟生活污水的处理结果表明,在水力停留时间为12 h的条件下,当进水温度为25-28℃,污染物COD、NH3-N、TN、TP和SS的浓度分别为350-450、26.4-36.9、27.0-38.5、1.7-2.6和267-345 mg/L时,相应的处理水中污染物去除率分别达到了95.7%、97.0%、51.4%、63.5%和93.9%。出水中各指标均满足《城镇污水处理厂污染物排放标准》（GB 18918-2002）中的一级排放标准。A new fluidized bed-fixed bed integrated reactor without sludge return and sedimentation tank was developed for efficiently treating dispersive domestic wastewater with low energy consumption.The performance of the reactor treating simulative domestic wastewater at 12 h HRT and 25-28 ℃ was investigated.Results showed that when the concentrations of COD,NH3-N,TN,TP and SS in influent were between 350-450,26.4～36.9,27.0-38.5,1.7-2.6 and 267-345 mg/L respectively, the average removal rates of above pollutants in effluent reached to 95.7% , 97.0% , 51.4% , 63.5% and 93.9% respectively. The water quality of effluent could meet the first class criteria specified in the national Diseharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918-2002 ）.
