户外饮水中的一些过滤方法

font-size: 16px; line-height: 28px;"> 当你找到的水源里有漂浮的异物或水质混浊不清时，可以在离水源3～5米处向下挖一个大约50～80厘米深，直径约1米的坑，让水从砂、石、土的缝隙中自然渗出，然后，轻轻地将已渗出的水取出，放入盒或壶等存水容器中，注意：不要搅起坑底的泥沙，要保持水的清洁干净。</span></div><div style="margin-top: 0px;

font-size: 16px; line-height: 28px;"> 当你找到的水源泥沙混浊，有异物漂浮且有微生物或蠕虫及水蛭幼虫等，水源周围的环境又不适宜挖坑时，可找一个塑料袋(质量好，不容易破的)将底部刺些小眼儿，或者用棉制单手套、手帕、袜子、衣袖、裤腿等，也可用一个可乐瓶，去掉瓶底后倒置，再用小 dao把瓶盖扎出几个凶，然后自下向上依次填入2～4厘米厚的无土质干净的细砂、木炭粉、细砂、木炭粉、细砂5至7层，压紧按实，将不清洁的水慢慢倒入自制的简易过滤器中，等过滤器下面有水溢出时，即可用盆或水壶将过滤后的干净水收集起来。如果对过滤后的水质不满意，应再制一个简易过滤器将过滤后的水再次进行过滤，即可满意。</span></div><div style="margin-top: 0px;

font-size: 16px; line-height: 28px;"> 三、沉淀法</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px;

font-size: 16px; line-height: 28px;"> 将所找到的水收集到盆或壶等存水容器中，放入少量的明矾或木棉枝叶(捣烂)、仙人掌(捣烂)、榆树皮(捣烂)，在水中搅匀后沉淀30分钟，轻轻舀起上层的清水，不要搅起已沉淀的浊物，这样，你便能得到较为干净的水了。</span></div><div style="margin-top: 0px; margin-right: 0px;

font-size: 16px; line-height: 28px;"> 一般说来，除泉水和井水(地下深水井)可直接饮用外，不管是河水、湖水、溪水、雪水、雨水、露水等，还是通过渗透、过滤、沉淀而得到的水，最好都应进行消毒处理后再饮用。那么，怎样进行消毒呢?方法如下：</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"><br/></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"> 1、将净水药片放入存水容器中，搅拌摇晃，静置几分钟，即可饮用，可灌入壶中存储备用。一般情况下，一片妆水药片可对1升的水进行消毒，如果遇到水质较混浊可用2片。目前，在野外军队里都采用此法对水进行消毒。</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"><br/></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"> 2、如果没有净水药片，可以用随身携带的医用碘酒代替净水药片对水进行消毒。在已净化过的水中，每一升水滴入3-4滴碘酒，如果水质混浊，碘酒要加倍。搅拦摇晃后，静置的时间也应长一些，20～30分钟后，即可饮用或备用。</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"><br/></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px;

font-size: 16px; line-height: 28px;"> 3、利用亚氯酸盐，即漂白剂，也可以起到消毒的作用。在已净化的水中，每升水滴入漂白剂三四滴，水质混浊则加倍，摇晃匀后，静置30分钟，即可饮用或备用。只是水中有些漂白剂的味儿，注意不要把沉淀的浊物一同喝下去。</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"><br/></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"> 4、如果以上的消毒药物均没有，正巧随身携带有野炊时用的食醋(白醋也行)，也可以对水进行消毒。在净化过的水中倒入一些醋汁，搅匀后，静置30分钟后便可饮用。只是水中有些醋的酸味。</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"><br/></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px;

font-size: 16px; line-height: 28px;"> 5、在海拔高度不太高(海拔2500米以下)且有火种的情况下，把水煮沸5分钟，也是对水进行消毒的很好的方法，且简便实用。在平原郊游或野炊时，多采用这种方法对河水、湖水、溪水、雨水、露水、雪水进行消毒以保证饮水和做饭的需求。</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti;

font-size: 16px; line-height: 28px;"> 6、如果寻找到的是咸水时，用地椒草与水同煮，这虽不能去掉原来的苦咸，即能防止发生腹痛、腹胀、腹泻。如果水中有重金属盐或有毒矿物质，应用浓茶与水同煮，最后出现的沉淀物不要喝。</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti;

font-size: 16px; line-height: 28px;"> 目前，有一种饮水净化吸管，在野外非常实用，形如一只粗钢笔，经它净化的水无菌、无毒、无味、无任何杂质，不需经过沸煮即可饮用，很轻便。</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;

font-size: 16px; line-height: 28px;"> 还有一些从国外进口的净水器，体积小效果好，能在较浑浊的液体中过滤出可饮用的纯净水。</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; word-wrap: break-word; "><span style="color: rgb(68, 68, 68); font-family: 'Microsoft Yahei', 'Helvetica Neue', 'Luxi Sans', 'DejaVu Sans', Tahoma, 'Hiragino Sans="Sans"GB', STHeiti; font-size: 16px; line-height: 28px;"><br/></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px;

font-size: 16px; line-height: 28px;"> 另外要提醒朋友们注意的是，在饮水紧缺的情况下，一定要合理安排饮用水，不要为一时口渴而狂饮。在野外工作或探险中，喝水也要讲究科学性。如果一次喝个够，身体会将吸收后多余的水份排泄掉，这样就会白白浪费很多的水。如果在喝水时，一次只喝一两口，然后含大口中慢慢咽下，过一会儿感觉到口渴时再喝一口，慢慢地咽下，这样重复饮水，既可使身体将喝下去的水充分吸收，又可解决口舌咽喉的干燥。一标准水壶(0-9）水量，运用正确的饮水方法，可使一个单兵在运动中坚持6～8小时，甚至更长些。</span></div></div> <br>表示网上看过了 现实还用不到 嘻嘻 谢谢楼主了 俺觉得蒸馏的好 记得乌鸦有净水器.. 知识是不错，但这都是到了迫不得已的时候才可以使用的。现在基本遇不到这种情况了 刚看完贝尔用木炭过滤 这个很有用啊，支持 ...自己带一个矿泉水瓶子 往里面塞满细沙 鹅卵石 烧炭，一切水都没问题 <br>实验室的滤纸净水应该也有效，可以准备几张 <br>学习贴，很好。 学习l~ 很有用啊 我上次看荒野生存上有用瓶子做净水的 8楼说得好 没有必要买那些昂贵的净水器 我不去沙漠 我们初中就学了，帮你顶个吧， 谢谢楼主，普及知识了
