How to protect water sources after floods, and how to protect water sources after floods

1. The principle of water source selection is sufficient water, good water quality, easy protection, and reasonable economy and technology. The order of selection is to choose spring water, deep well water, shallow well water, and then consider river water, lake water, pond water, etc.

2. In waterlogging areas, waters with less water pollution should be designated as drinking water intake points; In the flow of flood areas, drinking water sources should be selected in the upstream waters, and a certain area should be set aside to prohibit the discharge of feces, sewage and garbage in this area.

3. After the water is withdrawn, the well water should be used as the drinking water source as much as possible. Wells should have well platforms, well fences, manhole covers, and within 30 meters of the well's perimeter, it is forbidden to have toilets, livestock pens and other facilities that may pollute groundwater. There should be a special bucket for water intake.

4. The centralized drinking water source water intake point should be guarded by a special person.

What is a temporary emergency water supply.

1. Bottled water and bottled water are easy to transport and have safe water quality, which can be used to solve the problem of emergency drinking water.

2. Under the condition that the road traffic conditions permit, the waterwheel can be used to deliver water, the waterwheel space is closed, relatively hygienic and safe, and residents can take water nearby, which is convenient to use. Water delivery tools must be thoroughly cleaned and disinfected before use.

3. Select appropriate water treatment technology or equipment according to the water source situation, and establish a temporary centralized water supply station.

How to disinfect drinking water?

Drinking water disinfection is an important measure to ensure the safety of drinking water, and any water supply must be effectively disinfected before it can be drunk.

1. Boiling is the simplest and most effective way to disinfect, and it can be used in places where there is fuel. Disinfection can kill parasite eggs at the same time, and all drinking water is recommended to be boiled and drunk.

2. Drinking water disinfectant should be added to the water supply of centralized water supply facilities and equipment. The residual amount of disinfectant should meet the requirements of GB5749 "Hygienic Standard for Drinking Water".

3. Decentralized water supply, such as directly taking water from rivers, rivers, canals, streams, ponds, wells, springs and other water sources, should add drinking water disinfectant to the water container for disinfection. When choosing a chemical disinfectant, you should refer to the disinfectant instruction manual and use it under the guidance of a professional.

Also be aware that these drinking water are safe.

1. Do not drink raw water, try to drink boiled water, bottled water or drinking water approved by the disaster relief headquarters (bottled water prepared or sent by the purification equipment on site).

2. Do not drink unknown or polluted water, do not use unknown or polluted water to gargle, wash vegetables, etc.

3. The water taken by yourself must be disinfected before drinking.

4. Tanks, buckets, basins and other water containers should be disinfected frequently.

5. Consciously protect the source of drinking water and the environment, pile up domestic garbage, dump domestic sewage, and discharge feces in designated places.

After the floods, all water sources are unusable, and groundwater is the safest and unpolluted. It's safe to eat.

The methods to protect the clean water source of filial piety after the flood are: do not build toilets near the water source, keep livestock away from the water source in captivity, discharge live sewage away from the water source, and do not pile up garbage near the water source.

The water source is the general term for the ** and the form of existence of water. Water is the source of life, an important intermediary in the transmission of matter, information and energy, and an irreplaceable resource for the survival of organisms on the earth's surface. Water sources mainly exist in oceans, rivers and lakes, glaciers and snow-capped mountains.

They are renewed by atmospheric movements, etc. Water is a precious resource that human beings cannot do without engaging in production and living activities.

Flooding is a natural disaster that can have a great impact on people's production and life. In the event of a flood, the protection of water sources becomes particularly important. Protecting water sources is an important measure to protect the ecological environment and ensure the safety of people's lives and property.

First of all, flood warnings should be strengthened. Grasp the development trend of floods and the scope of hail hazards in a timely manner, and take measures as soon as possible to reduce the impact of floods on water sources.

Second, it is necessary to strengthen the construction of reservoirs and dams. Reservoirs and dams can effectively control flooding and protect water sources from flood impact and erosion.

Third, it is necessary to strengthen soil and water conservation. Soil erosion is one of the main causes of water damage. Measures should be taken to maintain and improve the soil, reduce soil erosion, and protect water sources.

Fourth, it is necessary to strengthen the rational use of water resources. It is necessary to formulate a reasonable plan for the use of water resources, reduce waste as much as possible, and ensure the sustainable use of water sources.

In short, the impact of flood disasters on water sources is inevitable, but the impact of flood disasters on water sources can be reduced by strengthening early warning, building reservoirs and dams, strengthening soil and water conservation work, and rational use of water resources.

Methods for the selection and protection of drinking water sources during floods:

In flooded areas, drinking water sources should be selected in the upstream waters, and a certain area should be demarcated, and the discharge of feces, sewage and garbage in this area is strictly prohibited.

In waterlogged areas, water areas with less water pollution should be designated as drinking water intake points to stop the discharge of feces, sewage and garbage in this area.

When the water source of centralized water supply is damaged or seriously polluted, a new water source should be selected immediately and a new water intake should be established as required.

Decentralized water supply uses well water as a drinking water source as much as possible.

During floods, the pollution of drinking water sources has the following characteristics

1. High turbidity, containing a lot of sediment;

2. Polluted by human and animal feces, bacteria breed, and the problem is more prominent when the population density is large;

3. Garbage, feces, animal carcasses, and various sundries enter the water body, and the organic pollution is serious, and the water body is easy to decay in high temperature climate;

4. Chemicals such as pesticides, fertilizers, and industrial wastes are flushed into the water, and there may be toxic substances.

Pollution by pathogenic microorganisms, deterioration of sensory properties of water quality and pollution by toxic substances are the three main factors affecting drinking water sanitation during flood disasters.

The choice of drinking water sources during floods should be to choose places that are not polluted and use disinfectants frequently.

Flood disaster is a natural disaster, some places are difficult to avoid, after the flood disaster in order to effectively ensure the safety of residents' tap water, we must reserve the water that residents need in advance, and at the same time to ensure the cleanliness and safety of residents' tap water in time. If necessary, some clean bottled water can be distributed.

In fact, there will be floods in our country every year, but this is also a sub-region, some places may be very serious, but some places are more close, but the tap water of residents will be more or less affected.

1. Reserve the water needed by residents in advance.

After all, once the flood disaster destroys the water of the water company, then the water used by the residents at home is not clean, and may bring a lot of sediment to affect the health of the residents, so in the flood-prone areas, then it is necessary to reserve the residents' water in advance, and once the flood disaster occurs, it can provide relatively clean and pure drinking water. <>

2. Ensure the cleanliness of residents' tap water in a timely manner.

At the same time, it is also necessary to ensure the safety of residents' tap water in a timely manner, after all, the residents' tap water is very much every day, especially for residents of a city, if the tap water is not clean, it will have an impact on the people's water use for a day, so in the time of floods, we must protect the overall water area of tap water in advance to be able to flow into the residents' homes in a safe, timely and clean manner. <>

3. Bottled drinking water can be distributed when necessary.

Flood disaster is a natural disaster, if it is a natural disaster is more serious area, after the water pipe is damaged or the cleanliness of the tap water is destroyed, it is necessary to distribute bottled drinking water, these also need to be stored in advance, after all, the affected area, if you do not distribute bottled drinking water to the masses, it is very troublesome, the human body lacks water is not strong, serious and even dry cough, causing other symptoms. <>

Alum water purification, so that the turbid water can become clear, boiling and disinfection, is the simplest and most effective disinfection method, vinegar soak sterilization, using a water purifier to purify, can effectively remove pollutants in the water, as well as bacterial impurities.

1. Export of clean water: After the flood, all the normal drinking water channels of residents are polluted and cannot be drunk. At this time, the ** agency often transports clean water from the outside.

However, it is necessary to pay attention to the disinfection of some water pipes, containers and transportation tools that are not usually used. Because these things are not usually used and are only used in emergencies, the disinfection must keep up. Disinfection vehicles are commonly used.

2. Container water storage: After the water supply in the affected area is interrupted, residents will use the most common and primitive method to store the purified rainwater or groundwater in tanks, basins, barrels and other containers, but the water in these containers is used for drinking. It must be cleaned and disinfected before.

It is necessary to check the tap water, disinfect it, and drink mineral water in a short time to avoid physical problems.
