摘　　要：对传统A/O工艺的硝化液回流方式和污泥培养方式进行改进,设计一种新型一体化内循环式A/O反应器,并以组合填料和火山岩为微生物载体,预处理后的模拟印染废水为原水,研究该反应器的启动过程。结果表明:进水COD、氨氮分别为205、22.9 mg/L时,A/O系统出水COD、氨氮分别为66.2、2.1 mg/L,降解率分别达到67.6%、90.9%。硝化液内回流比降至80%时,该一体化A/O反应器对模拟印染废水的有机物和氨氮仍有较好的降解作用。Based on the modification of nitrification liquid recycling mode and sludge cultivation mode of conven- tional anoxie-aerobic （A/O） process, a new type of integrated internal circulation A/O reactor has been designed. The start-up of the reactor is studied,using combined fillers and lavas as carriers,and the pretreated simulated printing and dyeing wastewater as raw water. The results show that when the influent COD is 205 mg/L and ammonia-nitrogen 22.9 mg/L, A/O system effluent COD is 66.2 mg/L and ammonia-nitrogen 2.1 mg/L. Their degrad- ing rates are 67.6% and 90.9% respectively. When the nitrification liquid internal reflow ratio reduces to 80%, the integrated A/O reactor has pretty good degradation capability for the organisms and ammonia-nitrogen in simulated printing and dyeing wastewater.
