摘　　要：为了提高厌氧氨氧化反应器的启动速度和水处理效率,自主研发一种新型的掺杂电气石的陶粒填料,附加聚氨酯软性填料,设计一种适合该复合式填料的一体化厌氧氨氧化反应器,并进行启动实验研究。结果表明,在进行污泥回流的情况下,该新型载体厌氧氨氧化反应器对废水的脱氮效果较好,NH_3-N和TN去除率约为95%以上,出现比较明显的污泥分层现象。因此,电气石陶粒+聚氨酯组合填料可作为一体化厌氧氨氧化反应器的载体并对反应器的快速启动具有促进作用。In order to improve the starting speed and water treatment efficiency of anaerobic ammonium oxidation reactor, a new type of tourmaline-doped ceramic filler was developed, polyurethane soft filler was also used. An integrated anaerobic ammonium oxidation reactor suitable for the composite packing was designed, and startup experiment was carried out. The results showed that the removal efficiency of NH3-N and TN was about 95%. Therefore, the tourmaline ceramic ＋ polyurethane composite filler can be used as a carrier for the integrated anaerobic ammonium oxidation reactor and has a catalytic effect on the rapid start-up of the reactor.
