在战时因为部队流动性较大而且地区转移范围也扩大,又因为争取时间的关系,所以对于水的卫生标准要求较低,按物理性、化学性、细菌学三方面分述如下: 1.战时水的物理性要求及检水法: (1)浑浊度:将被检验的水倒入有刻度,透明平底的圆柱形玻璃管中(一般有刻度的纳氏试管即可),在距离管底4匣米处放置印刷铅字(苏联第一号斯涅林字型),然后慢慢注水至看不清铅字字母为止。如该圆柱上高度小于10厘米就是表示非常浑浊的水,不可应用;自10—20厘米刻度内看不清铅字字母的水表示浑浊水;20—30
In the wartime, because of the mobility of the troops and the expansion of the scope of the transfer of the area, and because of the struggle for time, the water hygienic standards are less demanding. The three aspects are as follows: physical, chemical and bacteriological. Water physical requirements and watertight wartime law: (1) turbidity: the water to be tested into a graduated, transparent flat-bottomed cylindrical glass tube (usually graduated Nestea tube can), at a distance Bottom of the box at the bottom of the box 4 placed printed type (Soviet Union No. 1 Snell font), and then slowly water to the letter can not see so far. If the height of the cylinder less than 10 cm is very turbid water that is not applicable; from 10-20 cm scale can not see the letters of the water that cloudy water; 20-30
