摘要
针对目前单兵净水装置存在的耐污染性能低、使用寿命短及携带不便等问题,采用聚丙烯(PP)棉过滤膜、改性PES超滤膜和载银烧结活性炭等材料制备高效组合滤芯,并与单兵水壶微缩集成,研制了单兵净水壶。结果表明,该单兵净水壶具有净化效果好、耐污染、抗菌、轻便等特点,当滤芯载银质量分数为1%时,即可手动将龙洞水、珠江水和麓湖水等不同污染程度的野外地表水净化为符合GB 5749-2006的饮用水,有效净水量分别为40、35、35 L,净水体积流量分别为379、284、250 m L/min,可满足单兵在野外恶劣环境7 d内的饮水需求。
To solve the problems of traditional soldier purifier with low pollution resistance, short lifespan and poor portability, a soldier water purification kettle was developed by integrating soldier kettle with efficient combined filter composed of PP cotton membrane, modified PES ultra filtration membrane and silver loaded sintering carbon. Results showed that the soldier water purification kettle had the advantages of good purification efficiency, high pollution resistance, good antibacterial property and good portability. As the silver mass fraction of filter element was maintained at 1%, raw water from Longdong reservoir, Pearl River and Luhu with different levels of contamination could be manually purified and the effluent quality could reach the national drinking water standard of GB 5749-2006. Furthermore, the corresponding purification amount of 40 L, 35 L, 35 L and water volume flow rate of 379 mL/min, 284 mL/min, 250 mL/min, respectively, could also meet the need of drinking water within 7 d under wild environment for soldier.
