为了和肠道传染病作斗争,供给部队安全的饮水,水的氯化消毒,无疑是重要措施之一。然而在营、连实施饮水消毒却有着某些困难;最主要的是馀氯量不易掌握,不是失之太少,消毒不可靠;便是含量过多,氯味太大,同志们不願饮用。追究原因,主要有两个:(1)在野战部队内由于机动性大,驻地分散,僅团卫生连有饮水检验箱,因此常不能及时的帮助各连队对驻地水源进行需氯量(漂白粉加入量)测定、馀氯量测定等。(2)检验箱内联隣甲苯胺(俗称‘甲土立定’)测定馀氯法的标准比色液只有0.1、0.3、0.5毫克/升三种,标准液的貯存时间太长,有些
In order to fight intestinal infectious diseases, it is undoubtedly one of the important measures to supply the troops with safe drinking water and chlorination of water. However, the implementation of drinking water disinfection at camps has some difficulties. The most important thing is that the amount of residual chlorine is not easy to grasp, that is, it is not too much loss and the disinfection is not reliable. If the content is too high and the chlorine is too large, the comrades will not drink . There are two main reasons for this: (1) due to the large mobility and scattered resident stations in the field units, only drinking water test chambers are connected to the regimental health centers. Therefore, it is often not possible to help the various companies in a timely manner to carry out chlorination of the water sources in the stations (bleach added Quantity) Determination of residual chlorine determination. (2) test chamber linked o-toluidine (commonly known as ’a set of legislation’) Determination of residual chlorine method standard colorimetric solution only 0.1,0.3,0.5 mg / l three kinds of standard solution storage time is too long, and some
