摘　　要： 采用研制的添加生物亲和、亲水物质及活性磁种并磁化(2.5～5.0mT)的改性聚丙烯填料,进行表面润湿性、磁力挂膜以及模拟污水的生物降解试验等综合性能研究。结果发现,改性填料表面接触角比普通填料降低20%,亲水性得到很大提高;挥发性挂膜量增加近三倍,大大促进了生物膜的形成;同时,将COD为500mg/L的模拟污水完全降解,改性填料需10.5h,而普通聚丙烯填料则需22.5h。 The modified polypropylene packing with adding the substances of biological affinity and hydrophilicity, activated magnetic seeds and magnetisixation（25 ～50 C. G. S） was studied for its comprehensive performance of surface＇s moist nature, magnetic biological film forming and biological degradation of simulated sewage etc. It was discovered that the contact angle of the modified packing surface was decreased by 20% in comparison with common packings; its hydrophilia was improved greatly; volatile film forming quantity was increased by nearly three times, greatly promoting the formation of biological film .
