Abstract:采用自制壳聚糖改性聚丙烯无纺布膜为膜组件的A/O-MBR(厌氧/好氧-膜生物反应器)工艺对聚酯工艺废水的处理进行了研究,并与PVDF商品膜性能进
   行了比较研究.在近70 d的运行中,当进水COD在200500 mg/L之间,总氮在3045
   mg/L之间波动时,2种平板膜出水水质稳定.出水COD<40 mg/L,NH4+-N<0.5 mg/L,TN<5 mg/L,浊度<0.2
   NTU,均满足回用水水质要求和最新的辽宁省废水排放标准.实验中考察分析了污泥浓度和COD/TN对总氮去除率的影响.对比2种膜的运行结果,改性聚丙
   烯无纺布膜的出水水质略好于PVDF商品膜,但过膜压力稍大,膜通量稍小
