The water supply pipes of domestic buildings are mostly made of iron pipes or PVC pipes. At present, most of the water pipes of houses with the age of more than five years are iron pipes, and under the condition of long-time use, the walls of the water pipes can start to precipitate heavy metals, propagate sundry bacteria, microalgae and other harmful substances, gradually corrode the inner and outer walls of the water pipes to generate scale, the corrosion and scale are increasingly serious along with the longer use time, and the plastic pipes can start to adsorb a few of micro-organisms and form a biological membrane to be attached to the pipe walls, so that the corrosion and scale of the water pipes can also be caused. The pipe section from the back of the water meter to the household faucet of the main water of the user is often the easiest and most serious pipe section in a plurality of water pipes for storing dirty and dirty dirt. The reason is that the water in the main water pipe is basically in a flowing state, the water in the home is basically static and does not flow particularly at night, and in the environment, microorganisms contained in the water supply breed in large quantity and then die in large quantity, and then breed and die again, and after a long time, a certain biological film is slowly formed, and part of algae can be bred, so that more bacteria can grow. If the dirt of heavy metals, infectious microbes, microalgae and the like in the pipeline is absorbed by the human body little by little through the domestic water, although the human body can not be obviously treated in a short time, the health of the human body can be negatively influenced by drinking or using the water for a long time, such as liver cancer, kidney disease, skin disease and the like.
Currently, the solution to this problem is mainly to clean the water tank, or to add water treatment equipment at the point of use, such as electrochemical descaling, electric field descaling, magnetic water descaling, etc. These methods, while reducing the corrosion and fouling problems, have not been solved at the source and also have increased equipment investment.
