| 摘 要： | 采用两个小试规模的厌氧折流板反应器(AHR，Anaerobic Baffled Reactor)处理低浓度人工合成废水，分别接种厌氧消化池泥和好氧活性污泥，考察了反应器启动的情况，结果表明：好氧活性污泥能启动处理低浓度废水的ABR，但必须经过一段较长时间的培养驯化过程，启动较慢；接种厌氧消化池泥的反应器34d完成启动，化学需氧：N(COD，Chemical Oxygen Demand)去除率稳定在60％以上；与厌氧膨胀颗粒污泥床反应器(EGSB，Expanded Granular SludgeBed)试验的对比表明，ABR是一种适合处理低浓度废水的高效厌氧反应器．

| Abstract: | The startup of two lab-scale ABRs inoculated with activated sludge and sludge from a conventional sewage sludge digester, respectively, was investigated. The results indicated that the reactor inoculated with activated sludge could be started well, but the sludge must be domesticated for a period of time. The startup process was slow; the reactor inoculated with digested sludge completed the startup process within 34?d and the COD removal efficiency reached above 60?% stably. Compared with EGSB, ABR is a suitable high-rate anaerobic reactor to treat low-strength wastewater. |
