How to disinfect well water? How to disinfect well water

Well water disinfection method:

The first is the direct addition of bleaching powder disinfection method:

First, calculate the amount of bleaching powder according to the amount of well water: (When conditions permit, well water samples can be taken for chlorine demand determination.) The dosage of bleaching powder (fine) should be determined according to the water quality status of the water body, the amount of water, the prescribed chlorine amount and the effective chlorine content of bleaching powder (fine).

Formula for calculating water volume and dosing amount:

Round well water volume (m3) = [water surface diameter (m)] 2 0. 8 Water depth (m).

The amount of water in the square well (m3) = side length (m) side width (m) water depth (m).

The amount of bleaching powder should be added (g) = the amount of well water (m3) the amount of chlorine added to the well water and the available chlorine content of bleaching powder.

In daily work, it can be estimated according to the specific situation of well water quality, according to 5-8 grams per ton of water.

Then prepare the bleach solution and put the supernatant into the well water: put the required amount of bleaching powder (or bleach powder fine grinding) into a bowl or.

In a basin, add a little cold water to make a paste, add an appropriate amount of water, and let it stand for about 10 minutes. Pour the supernatant into the well water, shake it up and down several times with a bucket or stir it with a clean wooden stick for a few minutes to mix it well, and it can be drunk after half an hour.

Disinfect 2 3 per daydisinfection should be carried out 2 hours before taking water. When the well is contaminated, the amount of disinfection can be increased by 2 or 3 times.

The second is to continuously add bleaching powder to disinfect the method:

Put a certain amount of bleaching powder into a non-toxic plastic bag, bamboo tube, small mouth bottle, wooden box or clay pot and other containers, and drill a number of small holes (generally 4 6, the diameter of the holes is 0) on or next to the container.

2cm～。Add bleaching powder according to the quantity and quality of the water. Generally, 250g of bleaching powder is packed in bamboo tubes, 300g, and 250g and 500g are packed in plastic bags.

Plug or tie the mouth of the container with bleaching powder, put it into the well, suspend it in the water with a pontoon, and use the oscillation when taking water to slowly release the chlorine in the container from the small hole.

to maintain a certain amount of residual chlorine in the water. It can last for about 1 week after a single dose.

Tank water disinfection method: Tank water disinfection is one of the household water disinfection methods. First measure the amount of water in the tank, and then calculate the amount of bleaching powder according to the amount of water, and then prepare the bleaching powder into a disinfectant, drip into the water tank and stir and mix for half an hour, then it can be drunk.

If disinfected with semen bleach tablets (calculated according to the effective chlorine grams contained in each tablet), each bleach tablet can disinfect 50 kg of water, that is, add half a tablet to each bucket of water (about 25 kg). Sperm bleaching tablets can also be added directly. ?If the water quality is low, the dosage should be increased.

Newly dug wells, as long as there is no problem with the water quality and the water source is not polluted, generally do not need to be disinfected, only when the well wall is polluted when the well is dug and the building materials on the well wall carry harmful floating dust, it needs to be disinfected. Before disinfection, the well wall is washed with clean water, and then the dirty mud water is drained, and after the well is restored to a full water state, alum and other flocculants are put into the amount of 1 kg per cubic meter of water. Soak the flocculant for 24 hours, then drain the water, wait for the well to return to the full water level, and then put the disinfectant and fungicide such as bleaching powder according to the amount of kilograms per cubic meter of water, soak for 24 hours, and then drain the well, and repeatedly fill the water and drain it more than three times.

The most effective way to do well water disinfection is to use DCW hypochlorous acid solution. DCW hypochlorous acid is made by salt and water electrolysis, the effective chlorine concentration and pH value of the hypochlorous acid solution generated can be adjusted, and the addition of 2ppm DCW hypochlorous acid solution in the well water can kill various bacteria, viruses, fungi and other microorganisms in the well water efficiently, quickly and broad-spectrum, so as to ensure the sterility of water quality and the safety of drinking water.

Hello! First of all, you need to understand that the water body in each well is connected to the vast groundwater below, and the direct disinfection of the water body in the well has only a temporary effect.

Because no matter how much disinfectant you put in, it doesn't have much effect compared to the vast expanse of groundwater.

Proper method of disinfection:

Firstly, a 200ppm chlorine dioxide disinfectant solution was used to flush and disinfect the inner wall of the well.

After 30 minutes of disinfection, take the water from the well and put it in the water container at home.

After that, put 5 effervescent tablets of chlorine dioxide according to 1 ton of water, and after 15 minutes of disinfection, there are no bacteria and viruses in the water.

Well water is often disinfected with bleaching powder or bleaching powder tablets.

1) Direct chlorination disinfection: The time and frequency of disinfection should be determined according to the amount of water consumed and the time of carrying water. Under normal circumstances, public wells can be divided into morning, afternoon and evening once or twice a day, and household wells with small water consumption can be once a day.

Before disinfection, the amount of well water is calculated, and the calculation method is [water volume (m3) = well depth x water surface diameter 2, and then add 10 pieces of bleaching powder or 10 grams of bleaching powder per cubic meter (ton) of water. When dosing, put the required bleaching powder or crushed bleaching powder tablets in a bowl, add a small amount of cold water and stir well, and take the bleaching powder supernatant or bleaching powder essence original solution.

Pour it into the well, stir the water up and down several times with a bucket, and it can be used after half an hour.

2) continuous chlorination; Use plastic bags, bamboo tubes, polyethylene beverage bottles and other containers to fill 250 grams or 500 grams of bleaching powder, mix them into a paste with a small amount of water, and tie a buoy "wooden board or bamboo tube" to make the medicine bottle about 60 cm below the water surface. To disinfect 1 cubic meter <1 ton) well water, 1 2 holes need to be drilled in the upper part of the medicine bottle in advance, with a hole diameter of about 1 centimeter, and 1 2 small holes will be added for every 1 cubic meter increase in water volume. Increase the number of pores when the residual chlorine is insufficient, and decrease the number of pores when the residual chlorine is excessive.

When the water is lifted from the well, due to the water vibration of the medicine bottle, the disinfectant liquid slowly overflows from the small hole to achieve the purpose of disinfection. Depending on usage, the drug in each vial is usually changed once every 1-2 weeks. During use, care should be taken to prevent the bottle from coming to the surface, falling over and blocking the holes.

Chlorine dioxide.

1. Ordinary disinfection method:

That is, chlorine dioxide disinfectant is added to the well every day.

1) Before disinfection, the depth and diameter of the water in the well should be measured to calculate the amount of water in the well. Calculate the amount of disinfectant used based on the amount of water. Generally, the amount of chlorine dioxide added should be taken according to the clean state of the water.

2) Take an appropriate amount of chlorine dioxide disinfectant, add a small amount of water to activate it, and pour it into the well. *It is better to stir it in the well with a bucket or bamboo pole. *If the test is possible, the residual chlorine dioxide in the water should be preferably after half an hour.

3) Well water disinfection is generally carried out 1-2 times a day, in the morning and afternoon.

2) continuous chlorination;

1) Definition: Because the ordinary disinfection method needs to be disinfected every day, the workload is large, and the disinfection is often difficult to adhere to due to changes in objective conditions. As a result, users everywhere have created a continuous disinfection method that can extend the disinfection time, reduce the workload, and be easy to use.

2) How to use: choose bamboo tubes, plastic bags, ceramic jars, preferably plastic soda bottles, polyester cola bottles and other containers, put the chlorine dioxide disinfectant used for a week or more into the container, fill it with water, tie the container with a rope, and immerse the container in about 40-50cm below the water surface, and oscillate when borrowing well water, so that the chlorine liquid in the container continues to seep out and contact with the water, so that the well water often maintains an excess of effective chlorine for disinfection, so as to achieve the effect of continuous disinfection.

3) The amount of chlorine dioxide used in this continuous disinfection: the amount of chlorine dioxide agent for continuous disinfection should be multiplied by the chlorine dioxide concentration of 1-2mg l according to the volume when the well water is stable, and then the daily, weekly or longer amount of the agent is converted, and then added at one time, and the container is taken out for about a week to check and change the drug, and the residual chlorine dioxide in the water should be measured frequently and the amount of the agent added should be adjusted if possible.

3. Excessive disinfection method:

In special cases, excessive chlorination can be used.

1) This method is to disinfect well water according to about 20 times of the normal chlorine dioxide dosage (i.e., 10-30mg L).

2) Special circumstances refer to: * local intestinal infectious diseases that are suspected to be related to water; *Significant changes in coliform bacteria and chemical properties in well water; * Before the new well starts to be used; * After the repair of the old well; *When the well is flooded or falls into foreign matter, and there is a possibility of contamination; * When there is a large number of bloodworms or algae breeding in the well.

3) Specific method: first dry the well water, remove the dirt on the wall and bottom of the well, put the chlorine dioxide disinfectant according to 10-30mg l, beat the water after 10-12 hours, and then disinfect the water after the well is re-watered, and then disinfect and use it, if necessary, the well water can be drunk after passing the bacteriological examination.

Chlorine gas, the reference water that I usually drink is like this, slightly acidic, which is normal!

You can add some activated charcoal.

You can also look up industrial disinfection methods.

1. The deep well water that has been taken out can be disinfected by boiling, or disinfectants such as bleaching powder (fine) and chlorine dioxide can be added for disinfection.

2. If you want to disinfect the water in the well, you can add disinfectants such as bleaching powder (fine). Disinfectants should be dispensed regularly to ensure that the residual chlorine in the water is maintained at about the same level.

Bleaching powder or bleaching powder tablets are often used for disinfection. Bleaching powder contains effective chlorine with strong bactericidal ability. Generally, bleaching powder contains 25% to 30% available chlorine.

The disinfection method is as follows: pour a certain amount of the supernatant of bleaching powder into a well or water tank, and add about 10 grams of bleaching powder per ton of water or a semen tablet per load of water. <

The chlorine smell in the water is harmless to the human body, although it is safe.

Usually they will wash the walls or floors, or use some chlorine dioxide. It can also be disinfected repeatedly with alcohol or sprayed once every three days, so that it can be disinfected and sterilized. Generally, a large amount of cleaning agent is put into the water or activated carbon is used.

can be disinfected. Or wash some sludge.

For example, you can use disinfectant water for disinfection, and you can also use some disinfectant wipes on a regular basis, or you can use some hand sanitizer. Water from lakes, rivers and wells needs to be filtered and then disinfected with high technology.
