摘　　要：文章旨在研究提高生物膜附着基质亲水性能、缩短挂膜时间的相关改性处理方法,为该项技术应用于水产养殖废水处理工艺提供相关数据参考。研究选择筛绢网(40目)作为生物膜附着基质,选取氢氧化钠(NaOH)、氢氧化钙[Ca(OH)2]、盐酸(HCl)、高锰酸钾(KMnO4)、重铬酸钾(K2Cr2O7)和无水乙醇(C2H5OH)共6种试剂作为试验改性剂。通过基质吸附芽孢杆菌(Bacillus spp.)数量和对虾养殖池内挂膜效果来评价6种改性剂的改性效果。结果表明,10%HCl处理6 h后的基质亲水性更好,虾池挂膜效果最优,为该试验条件下生物膜附着基质亲水性改性的最适改性剂。We discussed the correlate parameters of modifiers enhancing the hydrophilicity of the biofilm-substrate and promoting the ma- ture of the membrane, which may provide references for their application in aquaculture wastewater treatment process. The silk net （ ap- erture 0.425 ram） was chosen as the biofilm-substrate and six modifiers [NaOH, Ca（OH）2, HCl, KMnO4, K2Cr2O7, C2H5OH] were tested as surface treatment reagents of substrate. The amount of Bacillus spp. adhered to substrate and the membrane-hanging effect in aquaculture wastewater provided some key evaluation indice for the six modifiers. The resuhs show that compared with the other treat- ments, the substrate treated by 10% HC1 for 6 h obtained the best hydrophilic ability and better membrane-hanging effect.
