摘要
为充分考察膜生物反应器的硝化性能 ,采用活性污泥比消化速率 ,对膜生物反应器处理氨氮废水的硝化性能进行了研究。结果表明 :在容积负荷 1.0 96kgNH+ 4 -N/(m3 ·d)的条件下 ,硝化性能稳定 ,氨氮转化为硝酸盐氮的转化率可达 99% ;亚硝化菌和硝化菌在活性污泥中占优势 ,系统中出现了胞外多聚物和可溶性微生物产物的积累。
In this work, the nitrification performance was studied in a membrane bioreactor for the treatment of wastewater containing ammonia nitrogen. The conversion rate of nitrate was above 99% under the volumetric loading rate of ammonia-nitrogen 1.096kg NH+ 4-N/(m3·d), and the nitrification performance was very stable. Extracellular polymeric substances (EPS) and soluble microbial product were accumulated in the membrane bioreactor. Nitrite bacteria and nitrate bacteria were prominent in the community.
