中文摘要：
采用自制的PVDF中空纤维膜组件构建浸入式膜生物反应器,进行了内电解-SMBR组合工艺处理难降解蒽醌染料（活性艳蓝X-BR）废水的试验.试验分为2组,一组为内电解出水直接进入的SMBR-3,另外一组为内电解出水经调节pH值达9～10后进入的SMBR-4.结果表明,组合工艺中2组SMBR对CODCr、色度和NH4＋-N的去除率均很高,且相差不大;但两反应器对TN的去除效果却有明显差异,由于良好生物铁絮体的存在,SMBR-3对TN的去除可高达92.8%,而SMBR-4对TN的去除只有67.5%.与pH值调节后进水相比,内电解直接进水导致活性污泥絮体粒径增大34μm,EPS总量明显增加,且微生物表面结构中有丝状菌出现,菌种也变得相对复杂.对SMBR膜材料进一步检测发现,内电解直接进水所形成的生物铁絮体还可有效减轻膜污染,使膜通量衰减变慢.
英文摘要：
Wastewater containing reactive brilliant blue X-BR anthraquinone dye was treated by internal electrolysis coupled with submerged membrane bioreactor（SMBR）,in which the self-made PVDF hollow fiber membrane modules were applied.During the experiments performance of SMBR-3 with internal electrolysis water directly entering was compared with SMBR-4 in which water entered after regulating pH to 9～10.The rates of both two SMBR on CODCr and NH4＋-N removal were high,but the efficiency on TN removal was very different,in which SMBR-3 had a high rate of 92.9% compared to just 67.5% for SMBR-4.The mean particle diameter of activated sludge in SMBR-3 was 34μm bigger than SMBR-4,and the change of EPS quantity was in the same trend.Some extra filamentous bacteria in microorganism surface texture were observed in solution which predicted the relative intricacy of cultures.The bio-ferric sludge forming in SMBR-3 was found to be useful to alleviate membrane fouling and made the flux decline become slower.
