摘　　要：采用厌氧折流板反应器(ABR)处理疫病动物废水,对其启动驯化过程进行了研究。结果表明,在逐级提高进水浓度的条件下,历经58 d成功启动反应器,当进水COD平均为8 120mg/L时,出水COD平均为491 mg/L,对COD的去除率可达94%,总产气量达到21.15 L/d,平均产气率为0.55 m3/kgCOD,疫病动物废水在ABR中可以得到高效降解。在启动过程中,随着进水浓度的提升,挥发性脂肪酸(VFA)在第1格室中不断积累,但同时废水在厌氧生物降解过程中可以产生大量碱度,保证了反应器内的中性环境条件,反应器未发生酸败现象。启动成功后,反应器各格室内的活性污泥主要以颗粒形态存在,且颗粒粒径沿水流方向逐渐减小,呈现明显的分级现象。The start-up and acclimation of anaerobic baffled reactor （ABR） for treatment of dis- eased animal wastewater were investigated. The results showed that the reactor started up successfully af- ter 58 d by gradually increasing influent concentration. When the mean influent COD was 8 120 rag/L, the mean effluent COD was 491 rag/L, and 94% COD removal rate was achieved. Besides, total biogas production and mean biogas production rate were 21.15 L/d and 0.55 m3/kgCOD, respectively. VFA accumulation mainly occurred in compartment 1 because of the increasing COD in the influent. Since a- bundant alkalinity was generated in the anaerobic process, reactor acidification was avoided. After the successful start-up, the activated sludge in each compartment was mainly granular sludge. The particle size of the granular sludge decreased along the flow direction, which presented an obvious classification phenomenon in the reactor.
