Water tower disinfection with what is the best thing to use

Disinfection method

Now tap water disinfection mostly adopts chlorination, the main purpose of public water chlorination is to prevent water-borne diseases, this method has been promoted to more than 100 years of history, with more perfect production technology and equipment, chlorine for tap water disinfection has the advantages of good disinfection effect, low cost, and almost no harmful substances. However, after understanding and studying the theoretical data, it is found that the use of chlorine for tap water disinfection still has certain drawbacks. Chlorinated tap water can produce carcinogens, and experts in the relevant field have also proposed many improvement measures.

Chlorine is easily soluble in water and combines with water to form hypochlorous acid and hydrochloric acid, and hypochlorous acid plays a major role in the entire disinfection process. For inorganic substances that produce odors, it can completely oxidize and disinfect them, and for living natural substances such as algae and bacteria, it can penetrate the cell wall and oxidize its enzyme system (enzymes are biological catalysts) to make it inactive, so that the life activities of bacteria are hindered and die. Hypochlorous acid itself is neutral, easy to approach the bacterial body and show a good sterilization effect, hypochlorite ion also has a certain disinfection effect, but it is negatively charged and difficult to approach the bacterial body (the bacterial body is negatively charged), so compared with hypochlorous acid, its sterilization effect is much worse, so the chlorine disinfection effect is better than the use of bleach disinfection.

At this stage, in addition to chlorine, disinfectants also include chlorine dioxide and ozone, and the use of alternative disinfectants can reduce the amount of harmful substances and improve treatment efficiency.

At present, the world's safe tap water disinfection method is ozone disinfection, but this method is too expensive to treat, and the retention time of ozone treated water is limited, as for how long it can be retained, there is no exact concept. Therefore, only a few developed countries currently use this treatment method.

In this case, the possibility of the occurrence of small high-rise slabs is relatively large, because the small high-rise is the water tower on the top of the building, and the buildings below six floors are generally directly supplied with domestic water. The rooftop domestic water tower needs to be equipped with ultraviolet lamps.

disinfection, and this ultraviolet disinfection lamp epidemic prevention department requires that it be replaced regularly.

It can be disinfected as follows:

Water is fed into the tower to the normal water level, sodium hypochlorite is added, and the effective chlorine content of the water in the tower is 100ppm, and it is disinfected for 4 hours. After 4 hours, put the detoxification water clean, rinse with clean water, and change the water 4 times.

If you are afraid of trouble, you can find a regular person to clean it.
