摘要
开展低温下膜-生物活性炭工艺深度处理回用水的试验研究,探讨该工艺低温运行的可行性及作用机制。结果表明,采用HRT为3h的膜-生物活性炭反应器对回用水中有机物具有良好的去除效果,CODCr、UV254、UV410的去除率分别稳定在33%、35%、40%;对NH3N的去除效果不明显,其平均去除率在15%左右,主要受原水浓度过高的影响。同时与其他工艺进行对比研究,结果表明,由于该工艺结合了膜分离、活性炭吸附、生物降解三者的综合作用而表现出明显的优势。
The feasibility and mechanism of advanced treatment effluents sampled from a secondary treatment plant of sewage in Beijing by membrane-biological activated carbon technology at low temperature were studied. It was found that the removal of organic compounds was quite effective at a hydraulic retention time （HRT） of 3 h, with 33%,35% , 40% and 15% CODcr,UV254 , UV410 and ammonia removals, respectively, In comparison with the conventional biological activated carbon process, it was considered that the process developed in this work has distinct advantages such as the synergistic effects of membrane separation, activated carbon adsorption and biological degradation.
