近年来,我公社开展了井水消毒工作,在工作中摸索了一种既简便,又能达到目的的方法,现介绍如下: 简易消毒器的制作与使用方法:用500克客量的大口瓶一只,在瓶盖上钻2～3个直径为8～10毫米的圆孔,套在尼龙编织的小网袋里,再用两头有节的毛竹筒作为浮标,用尼龙绳把装瓶的尼龙网袋与毛竹筒连在一起,使用时把新鲜的漂白粉装入瓶内(约为瓶容量的五分之三,不能装满和装得过紧),加水少许调成糊状,盖好瓶盖,然后瓶口朝下,倒置于网袋中,投入井水里,借用吊水时的震荡力,使余氯不断溢出,这样一次投药可持续消毒10～15天。为使消毒器不致漂浮到井边而使受震动力小、有效氯不易逸出,我们又以一定长度的木棒结在圆筒外面,以一个圆的弦的方式使之与井中心的距离保持在40cm,这样吊水时消毒器受震动大,有效氯逸出较多,消毒效果好。简易消毒器与井水面的直径关系:见表1。井水水面直径越大,需要瓶子数目多,需漂白粉量也相应增多,且瓶盖上的圆孔要大, In recent years, my commune carried out well water disinfection work, worked out in a way that is not only easy, but also to achieve the purpose, are described below: Simple sterilizer production and use: 500 grams of consumer vials One, drilled in the bottle cap 2 to 3 diameter of 8 to 10 mm round hole, set in a small net woven nylon bag, then use two knotted bamboo tube as a buoy, with nylon rope bottling Nylon mesh bags and bamboo tube together, the use of fresh bleach into the bottle (about three-fifths of the capacity of the bottle, can not be filled and packed too tight), add a little water into a paste, covered bottles Cover, and then bottle down, upside down in the net bag, into the well water, borrow water pressure when the shock, so that residual chlorine overflow, such a drug administration sustainable disinfection 10 to 15 days. In order to make the sterilizer does not float to the well side so that the shock force is small, effective chlorine is not easy to escape, we have a length of wood knot in the cylinder outside, in a round chord way to make it with the well center distance Maintain at 40cm, so when the water was disinfected by vibrating, effective chlorine escaped more disinfection effect. Simple disinfection and well water surface diameter: see Table 1. Well water surface diameter, the need for a large number of bottles, the amount of bleach also increased accordingly, and the bottle hole on the hole to be large,
