摘　　要：为了提高厌氧氨氧化菌处理酿酒废水的脱氮性能,采用11 L的UASB反应器,接种酒厂废水处理站厌氧消化污泥,利用悬浮多孔球型生物填料对生物膜的附着作用,在温度为(35±2)℃条件下,以稀释后的酿酒黄水为进水,启动反应器。结果表明,反应器的启动经历了污泥性能适应期、提高期和稳定期3个阶段。反应器在第209天进入稳定期,NH_(4)^(+)-N和NO_(2)^(-)-N去除率分别达75%和99%;反应器污泥为褐色,并在反应器下部形成褐色颗粒污泥。利用UASB厌氧氨氧化反应器处理稀释后的酿酒黄水,可以有效提高该废水的脱氮处理效率。In order to improve the denitrification performance of anammox bacteria treating brewing wastewater,11 L UASB reactor seeded with anaerobic digestive sludge in brewery wastewater station was adopted.Utilizing the biological membrane carriers′adhesive action of suspended porous spherical biological filler,taking attenuated brewing yellow water as influent water,the reactor could be started-up.The results showed that,the reactor had undergone three stages:sludge performance adaptation period,improving period and stabilizing period.When the reactor went to stabilizing period in 209 d,the removal rates of NH_(4)^(+)-N and NO_(2)^(-)-N reached 75%and 99%respectively,the sludge color in the reactor was brown and granular sludge was found at the bottom of the reactor.It could be seen that using UASB anaerobic ammonium oxidation reactor to treat attenuated brewing yellow water could effectively improve the nitrogen removal efficiency.
