| 摘 要： | 为了防止微生物流失,向厌氧序批式反应器(ASBR)中投加纤维膜(无纺布)作为厌氧氨氧化菌的载体,而使ASBR改为厌氧序批式生物膜反应器(ASBBR),研究了厌氧氨氧化菌活性恢复及富集培养过程中氮负荷提高对ASBBR的影响。经过23d的培养,厌氧氨氧化菌的活性恢复到原有的水平,然后提高TN容积负荷培养厌氧氨氧化菌。至132d时,反应器TN容积去除负荷达到了2.060kg/(m3·d)。整个过程中NH4+-N和NO2--N去除率一直保持在98%以上。当厌氧氨氧化菌活性恢复后,NH4+-N、NO2--N消耗量与NO3--N生成量之比最终趋于一定值(1.00∶1.30∶0.25)。在培养过程中,污泥颜色逐渐由灰色变为红棕色,最终变为浅红色。结果表明,反应器运行很稳定,NH4+-N、NO2--N出水浓度非常低,在短时间内能提高到较高的容积去除负荷。可见,ASBBR很适合厌氧氨氧化菌的富集培养。

| Abstract: | A developed anaerobic sequencing bath reactor (ASBR), with non-woven fabric used as carriers to prevent the loss of micro-organisms, was built for the reactivation and enrichment of ANAMMOX bacterium. The effect of nitrogen loading on performance of ASBR was investigated. The activity of sludge for ANAMMOX was recovered in the first stage (day 1 to day 23) and then enriched in the second stage (day 24 to day 132) by increasing influent nitrogen concentration. After the first stage of operation, the ratio am... |
