国内外在个人滤水器的研究方面有不少报导,现仅就收集到的部分资料介绍如下。军队卫生研究所石茂年年等,曾于1962年研制了个人用过滤水壶。即在原来军用塑料水壶装配上硅藻土滤管,每10～15分钟可装满一壶水,滤过的水质清洁透明,滤管重242克。经试验证明,它能陡浑浊度大于835ppm的水降至10.5ppm以下。水中含大肠杆菌每毫升10万个或芽孢菌每毫升2万个,经过滤后均可完全消除。但由于滤管容易破损,滤管装配时嵌合不严密,有漏水现象,不能保证过滤效果,致使个人用过滤水壶没能推广应用。第一军医大学军队卫生教研室曹健等
At home and abroad in the personal water filter research has many reports, now only some of the information collected as follows. Military Health Institute Shimao years, etc., who in 1962 developed a personal filter kettle. In the original military plastic water bottle equipped with diatomaceous earth filter tube, every 10 to 15 minutes can be filled with a pot of water, filtered water clean and transparent, 242 grams of filter pipe weight. Test proved that it can turbidity greater than 835ppm turbidity water to 10.5ppm or less. Water containing Escherichia coli per 100 000 or Bacillus spores 20,000 per milliliter, after filtration can be completely eliminated. However, due to easy to damage the filter, filter tube assembly is not tight fitting, there is leaking phenomenon, can not guarantee the filtering effect, resulting in personal use of filtered water bottles did not promote the application.
