Give priority to drinking bottled water or boiled water. If there is no condition to boil water, you can drink water disinfected with disinfectant. Don't drink polluted water, and don't wash it with turbid and colored water.
Well water and spring water are the first choice for water intake, and river bank seepage water can also be selected.
Water containers should be disinfected frequently and cleaned with clean water.
Water that smells like disinfectant tastes safer.
The order of selecting water sources is well water, spring water, mountain stream water, river water, reservoir water, lake water and pond water. However, according to the actual situation and the results of water quality analysis, water source protection areas should be delineated, water sources should be identified and water source protection should be strengthened.
Protect drinking water sources.
2. Measures to protect drinking water sources
Within 50 meters around the water source well or 30 meters along the surface water source, it is forbidden to build toilets and livestock pens, to discharge feces, sewage or dump garbage, and not to spray pesticides at the water source.
Feces should be uniformly disinfected and managed, and the bodies of animals and livestock should be removed in time and immediately buried. The landfill should be more than 0/50m away from the water source/kloc-and away from the residents' daily living area, and the landfill depth should be more than 40cm. Lime should be added in proportion when landfill is completed, and the landfill site should be marked after landfill is completed.
A simple diversion ditch is set in the water source area to prevent rainwater or sewage from carrying pollutants directly into the water source area or its upstream area; For water wells, pollution interception measures should be set around, well platforms should be built, drainage ditches should be dug, and water wells should be covered to prevent pollutants from entering. Disinfect well water regularly every day and use public buckets to get water.
3, drinking water disinfection method
Household and personal water: boiling disinfection is reliable, and the method is simple and easy. Halogen preparations such as bleaching powder can also be used for disinfection of drinking water.
Well water: calculate the well water quantity according to the depth and diameter of well water, and calculate the dosage of disinfectant in proportion.
Centralized water supply unit: to remove pollutants and sludge left over from disasters and clean water-making facilities and equipment, it is necessary to ensure that the disinfectant stays in the clean water pool for more than 30 minutes, and the free residual chlorine content in the factory water is detected within the range of 0.5 ~ 65438 0.0 mg/L, or to ensure that the free residual chlorine content in the end water of the pipe network reaches 0.65438 0 mg/L. ..
