This study evaluated the treatability of textile wastewaters in a bench-scale experimental system, comprising an anaerobic biofilter, an anoxic reactor and an aerobic membrane bioreactor (MBR). The MBR effluent was thereafter treated by a nanofiltration (NF) membrane. The proposed system was demonstrated to be effective in the treatment of the textile wastewater under the operating conditions applied in the study. The MBR system achieved a good COD (90-95%) removal; due to the presence of the anaerobic biofilter, also effective color removal was obtained (70%). The addition of the NF membrane allowed the further improvement in COD (50-80%), color (70-90%) and salt removal (60-70% as conductivity). In particular the NF treatment allowed the almost complete removal of the residual color and a reduction of the conductivity such as to achieve water quality suitable for reuse.
本研究在一个包括厌氧生物滤池、缺氧反应器和有氧膜生物反应器（MBR）的中试实验系统中评估了纺织废水的处理能力。此后，MBR 出水通过纳滤（NF）膜进行处理。在所应用的操作条件下，该系统被证明可有效处理纺织废水。MBR 系统实现了良好的 COD（90-95%）去除率；由于存在厌氧生物滤池，还实现了有效的颜色去除（70%）。NF 膜的添加允许进一步提高 COD（50-80%）、颜色（70-90%）和盐去除率（60-70%作为电导率）。特别是 NF 处理允许几乎完全去除残留颜色，并降低电导率，从而使水质适合再利用。
