Now a lot of people's living water, especially some special rural water still directly drink river and lake water, in fact, these water from one hand should be the best, but with more and more factories, it is difficult to avoid pollution, so this type of water is likely to not meet the sanitary requirements, if the pollution is more serious is likely to cause some poisoning, So how do we disinfect drinking water, drinking water disinfection should use calcium hypochloric acid, which is bleach powder to directly disinfect drinking water. This bleaching powder contains good sterilization ability effective chlorine, usually we will put water in the water tank, according to 50 kg of water per load of calcium hypochlorite 0.5 to 0.7 grams, of which the general calcium hypochlorite contains 24% of the effective chlorine, bleaching contains machine chlorine 58% to 68%. After adding calcium hypochlorite, we put calcium hypochlorite in the bowl or basin into paste at first, and then poured into the cylinder with a clean stick to stir, half an hour to an hour or so can be directly consumed, the smell of water is harmless to the human body, so just rest assured.

Of course, calcium hypochlorite should also pay attention to a few points, the first high water temperature sterilization effect is good, so when the water temperature is too low can increase the appropriate amount of bleach, water turbidity will affect the sterilization effect, but also can first muddy water precipitation before disinfection.

The amount of water used varies,

The residual chlorine in the sewage after disinfection shall reach 4mg/L ~ 6mg/L according to the calculation of residual chlorine in the sewage after disinfection.

Mix 10,000 ~ 20000 ≥120 feces.
