摘　　要：通过添加亲水性、生物亲和性及磁性等物质对普通聚氯乙烯生物填料进行改性,研究了改性填料的亲水性、生物亲和性以及抗冲击性能,考察了改性PVC生物填料用于模拟船舶废水处理的效果。实验表明,改性填料的水滴静态接触角降低了17%,含水率提高了76%,并能承受更高的气液比。研究表明改性PVC生物填料的亲水性、生物亲和性有很大程度改善,完全可以用于各种生活污水处理。One polyvinyl chloride （PVC） biofilm carrier was modified with biocompatible, hydrophilic and magnetic additives. Its performance of hydrophile, biocompatibility and adaptation to impact load were studied. The effects of modified PVC biofilm carrier on biological treatment of simulated wastewater were studied. The results show that the surface angle of contact of PVC reduces 17%, and the adsorbed water content enhances 76%, adaptability to impact load was improved very much. The biocompatible and hydrophilie performance of the modified packing were meliorated at a great extent,and could be used in wastewater.
