| 摘要:本研究采用造纸工艺，以活性炭纤维、聚丙烯腈浆粕、TiO2颗粒为原料，制备成具有杀菌功能的活性炭滤芯，并对滤芯进行了性能测试。结果表明，所制成的活性炭滤芯净水效率高、抗压强度好，还具有杀菌功能。随着浆粕用量的增加，滤芯的孔隙率、平均孔径和最大孔径均减小，孔径分布更集中，其碘吸附值、亚甲基蓝吸附值、余氯吸附值均有所下降。当浆粕添加量为30%时，孔隙率为91.6%，碘吸附值、亚甲基蓝吸附值、余氯吸附值分别为86.75%、91.97%和92.48%。滤芯在紫外灯照射条件下，杀菌率保持在90%以上。通过对滤芯的出水水质测试，测试结果达到GB 5749—2022的要求。 |
| Abstract:This paper used papermaking technology to prepare activated carbon filter cartridges with sterilization function using activated carbon fibers (particles)， polyacrylonitrile pulp， and TiO2 particles as raw materials， and conducted performance tests on the filter cartridges. The results showed that the activated carbon filter cartridge produced had high water purification efficiency， good compressive strength， and also had sterilization function. As the amount of pulp increased， the porosity， average pore size， and maximum pore size of the filter element decreased， with a more concentrated pore size distribution. The iodine adsorption value， methylene blue adsorption value， and residual chlorine adsorption value declined accordingly. When the pulp addition reached 30%， the porosity was 91.6%， while the iodine adsorption value， methylene blue adsorption value， and residual chlorine adsorption value were 86.75%， 91.97%， and 92.48%， respectively. The sterilization rate of the filter element remained above 90% under UV lamp irradiation conditions. By testing the effluent quality of the filter element， the test results met the requirements of the national standard GB 5749—2022. |
