Abstract:The treatment of washing and bleaching wastewater of the wheat straw pulping line by using an immersed flat membrane bioreactor prepared in lab was studied. The experimental results showed that the CODCr, color, and SS removal efficiencies reach 90.0%, 92.3% and 96.0% respectively. The effluent quality can meet the “the paper industry water pollution discharge standard” (GB3544—2008) requirements. The membrane pollution can be reduced by optimizing the operation parameters.
