【摘要】 本研究采用前置缺氧/好氧膜生物反应器(Anoxic/Oxic M em brane Bioreactor,A O M B R)处理废水,分别对N H4+-N及总氮(TN)的去除效果、硝化/反硝化能力以及影响因素进行了研究。试验结果表明:在碳源充足、水力停留时间(H RT)为6.5h、污泥泥龄(SRT)为30d、pH值范围为7.0～8.5条件下,进水N H4+-N平均值为240m g/L时,反应器能够保持良好的硝化、反硝化能力,出水N H4+-N值能稳定在2.5m g/L左右,平均去除率为98.5%,TN平均去除率为65%。更多还原

【Abstract】 A study of high level ammonia-nitrogen wastewater treatment with anoxic/aerobic membrane bioreactor(AOMBR) was carried out. The removals of NH+4-N and total nitrogen(TN), nitrification/denitrification and their influencing factors were studied. The results showed that under the conditions of abundant carbon source, hydraulic retention time=6.5h, sludge age=30d and pH value ranging from 7.0 to 8.5, when the average value of NH+4-N in effluent could be stable at 2.5mg/L or so and the average removal rate was 98.5%, the average removal rate of TN was 65%.更多还原
