摘要
目的研制一款轻便、快捷的净水装置,用于野外无电源环境。方法采用超滤技术,依靠手动增压方式,通过pp棉滤材、椰壳活性炭滤材和聚丙烯晴超滤膜三级过滤组成净水装置,并就净水的浊度、细菌总数、大肠菌群等指标进行检测,以评价其净水效果。结果经过本装置滤过的天然水源均无异味,口感好,大肠杆菌群(cfu.100mL-1)、细菌总数(cfu.mL-1)均未检出;贾第鞭毛虫和隐孢子虫呈阴性,浊度≤3NTU。结论用本装置处理的天然水达到饮用水卫生标准,可直接饮用。
Objective To design a portable and efficient water purification device which can get clean drinking water quickly from natural water in the wild field where there is no electric power to provide. Methods The purification device which relies on manual booster and ultrafiltmtion technology is made up of three filtration layers, filter materials of PP cotton, active carbon of coconut shell and effect of purification is evaluated by water turbidity, total bacteria count, coliform group and so on. Results The natural water cleaned by this purifier which has no peculiar smell and tastes good was with no coliform group（cfu. 100ml- 1）and bacteria（cfu.mL- 1）. The giardia lamblia and cryptosporidium are negative, and the turbidity is less than or equal to 3NTU. Conclusion The natural water processed by the device can meet the health standards and be directly drunk.
