A large number of human and animal excrement, garbage, animal corpses, etc. are washed into the water by the flood, resulting in a sharp increase of biological pollution in the water, so the first thing after the flood is to prevent the plague, so how to prevent the plague after the flood?
How to prevent epidemic and disinfect drinking water after flood
A large number of human and animal excrement, garbage and animal corpses were washed into the water by the flood, which caused a sharp increase of biological pollution in the water, and all kinds of microbial pollution were extremely serious. After the flood, the above-mentioned polluted water is still left in the ponds and wells, and the dirt is deposited on the bottom of the water. Although the appearance is clear, the water quality is still poor. Therefore, the water in the disaster area must be specially disinfected and tested before it can be used as drinking water.
We advocate drinking boiled water instead of raw water. Waterworks should strictly disinfect the drinking water, properly increase the amount of chlorine during the flood, and ensure the public drinking water sanitation. For well water, landscape water and so on, the public had better not use it as drinking water. If it must be used, it must be disinfected with bleaching powder or bleaching essence tablet. The bleach tablet is measured by 1 tablet per 100 Jin of water. The method is: grind the bleach tablet into a paste with clear water, pour it into the water to be disinfected, mix it fully, cover it and leave it for 30 minutes before use. Bleaching powder (refined tablet) will fail in case of high temperature, bright light and humidity, so it must be placed in a place that can avoid light, dry and cool (for example, use a brown bottle to tighten the bottle cap for storage).

It is easy to pollute water source and breed flies. Temporary toilets shall be set up in the resettlement site for the victims, and they shall not urinate anywhere.
10 parts of fecal water and 1 part of bleaching powder are used for fecal disinfection, and then they are stirred and buried in the designated place 2 hours later. For feces of patients with intestinal infection, mix 5 parts with 1 part of bleaching powder or add the same amount of quicklime for 2-4 hours, and then bury them in the designated place.
Animal carcass disposal
For the dead animals caused by the flood, they should be disinfected in time and buried under 1.5-2 meters. The burial point shall be located at a place with high terrain and far away from water source. The body used 10% bleaching powder clarified liquid, spray at 200 ml / m2, buried 1-2 hours later, and then covered with the powder of 20-40 g / m2 of bleach powder on the body, then buried it in the soil. Transport vehicles and tools should be sprayed with 1-2% bleaching powder clarified liquid for 1 hours. (this article is exclusively compiled by WYH, editor of sihai.com.

After the flood, there will be high temperature weather, and the food is easy to deteriorate. The food preserved during the flood is also easy to mildew, especially the meat of drowned livestock is more likely to deteriorate, and the temporary stalls often do not pay attention to sanitation, so we should pay attention not to drink raw water; wash hands before and after the meal; do not eat the food that is rotten or soaked in the flood, do not eat the drowned or dead livestock; do not wash mouth with dirty water or wash fruits and vegetables; dishes and chopsticks should To boil or disinfect the cupboard, the knife, chopping board and dishcloth should also be strictly disinfected; the raw and cooked food should be stored separately; the aquatic products and seafood food should be cooked thoroughly before eating.
