用漂白粉消毒饮用水是改善水质的重要方法,它不仅在军队中占有重要地位,而且在世界各国的大小城市中的自来水厂也多采用此种方法,它具有很高的杀菌力,成本又低,这对部队巨大的用水量,更显示了它的优越性。但在部队野战或野营等紧急情况下饮水氯素消毒尚有—些缺点:如接触时间长,有效氯的不稳定性和目前連队还不能经常进行有效氯的测定,以掌握其确实含量等,都影响了饮水消毒效果的可靠性。为了解决部队在野战或野营等紧急情况下的饮水消毒问题,我们试用2%的碘溶液进行了饮水消毒的效果观察。由于实验次数不多,材料尚不全面,现仅将初步结果,提供部队野营及作战情况下饮水消毒工作之参考。一、方法:1.将研碎的碘片2克与1.4克碘化钾溶于少量蒸馏水,不断捣拌至溶解,再加水到100毫升,配成2%的碘溶液。2.按每升地下水中分别加入2、4、6毫克活 Disinfection of drinking water with bleach is an important way to improve water quality, not only in the military occupies an important position, but also in the world’s large and small cities in the water plant also use this method more, it has high bactericidal power, low cost , This huge amount of water for the troops, but also shows its superiority. However, disinfection of drinking water with chlorine in emergencies such as military field operations or camping is still lacking. Some disadvantages: For example, the long-term exposure, the instability of available chlorine and the continual determination of available chlorine at present in order to know the exact content , Have affected the reliability of drinking water disinfection effect. In order to solve the issue of drinking water disinfection in emergencies such as field operations or camping, we tried the effect of disinfecting drinking water with 2% iodine solution. Due to the small number of experiments, the material is not yet comprehensive, and preliminary results will be provided only to provide reference for disinfection of drinking water during camping and combat operations. First, the method: 1. The broken pieces of iodine 2 grams and 1.4 grams of potassium iodide dissolved in a small amount of distilled water, continue pounding to dissolve, add water to 100 ml, dubbed 2% iodine solution. 2. Add 2, 4 and 6 milligrams per liter of groundwater
