【摘要】 以活性炭纤维、纳米纤维素、聚丙烯、抗菌母粒等为原材料，采用湿法成型技术制备了第二代纳米活性碳纤维滤芯，结合湿法成型技术和熔融喷丝技术制备第三代复合型抗菌滤芯.采用XRD和SEM表征了第三代复合型抗菌滤芯的结构与表面形貌，并与市售的第一代烧结型活性炭滤芯和第二代纳米活性碳纤维滤芯进行了水中化学需氧量（COD）、色度、浊度和余氯等污染物的过滤性能对比试验.结果表明：第三代复合型抗菌滤芯在过滤微量有机污染物、悬浮污泥颗粒、氯化消毒副产物，以及过滤铅、镉两种重金属离子等方面的表现明显优于第二代纳米活性碳纤维滤芯和第一代烧结型活性炭滤芯.此外，第三代复合型抗菌滤芯对浊度的去除率大于94%，对COD的去除率大于53%，对色度去除率大于97%，对余氯去除率大于98%,对金属离子（铅、镉）的去除率大于98%，其效果良好；该滤芯受污染物浓度、水样温度变化的影响较小，净水效果稳定且显著.更多还原

【Abstract】 In this paper, activated carbon fiber, nano-cellulose, polypropylene, antibacterial masterbatch were used with wet forming technology to prepare the second generation of nano active carbon fiber filter. In combination with wet forming technology and melt spinning technology, the third generation of composite antibacterial filter was prepared. The structure and surface morphology of the third generation filter were characterized by XRD and SEM. The filtration effects of the three filters on COD, chroma, turbidity, residual chlorine and other pollutants were compared. The results showed that the performance of the third-generation composite antibacterial filter was significantly better than that of the second-generation filter and commercial sintered filter in filtering trace organic pollutants, suspended sludge particles, chlorination disinfection by-products, heavy metal ions and so on. The third-generation filter was less affected by the pollutant concentration and water sample temperature change. The water purification effect was more significant and more stable, and the influence of external factors is less, the turbidity removal rate is above 94%, the COD removal rate was maintained above 53%. The chroma removal rate is greater than 97%, and the residual chlorine removal effect is more than 98%. It also has a good removal effect on heavy metal ions, with a removal rate of > 98%.更多还原
