[Treatment of dying wastewater from a woolen mill with a pilot-scale anaerobic/oxic membrane bioreactor (A/O MBR)].
A pilot-scale (10 t/d) anaerobic/oxic membrane bioreactor (A/O MBR) was used for treatment of dying wastewater from a woolen mill. The results showed that when COD, BOD5 and color in the influent was 179-358 mg/L, 44.8-206 mg/L and 50-240 dilution times (DT), the average COD, BOD5 and color of A/O MBR effluent was 20.2 mg/L, 1.6 mg/L, 25 DT respectively. The removal of COD, BOD5, color, turbidity was 92.1%, 98.4%, 60.7% and 98.9% respectively. Each quota of the treated water met the gray water standards (CJ25.1-89). The A/O MBR process has many advantages, such as stable performance, simple operation, easy management etc. The result of this work could be reference for the designing of industrial scale A/O MBR process for treatment of the woolen mill wastewater.
