ABSTRACT: This
study demonstrated the feasibility of implementing of MBR in pharmaceutical
wastewater independently, and concluded different applications of MBR in
industries. Membrane bioreactor (MBR) technology was a new wastewater treatment
technology with a combination of membrane separation technology and biological
treatment technology, which had unique advantages on pharmaceutical wastewater
treatment. The modified membrane rector design provided a significantly lower
concentration of NH3-N, Phosphorous, Total Nitrogen and COD around
the membranes, and subsequently a more sustainable membrane performance due to
much lower overall fouling rates. In this paper, the classification and
structure of biological waste water treatment by using MBR technology were
summed up along with some examples of MBR in industrial wastewater treatment,
which was emphatically analyzed and discussed. Finally, the prospect of MBR in
industrial wastewater treatment was described. The industrial wastewater was a
high-strength wastewater which had characteristics of complicated constituents,
high organics concentration, highly toxic.
