Background

One of the main objectives of drinking water treatment is to reduce the microorganisms and inactivate or remove all pathogenic bacteria to an acceptable level. According to the regulation of the water quality standard of tap water for construction in China, namely the water quality standard of drinking water, the total detected amount of bacteria in the tap water is required to be not more than 100CFU/ML, and the total coliform group is not more than 2/L water. According to the regulation of the water quality standard drinking water quality standard issued by the Ministry of construction in China, the total detected amount of bacteria in drinking water is required to be not more than 50CFU/ML, and the total coliform bacteria can not be detected.

In the process of conveying tap water to a user terminal for use, because higher organic matters are left in the tap water, a biological film is formed in a transmission and distribution pipe network, and residual chlorine in the water is consumed to cause the growth of microorganisms; in addition, the secondary water supply of the water tank in the water distribution pipe network often exposes the water to the air or is not tightly sealed, so that a large amount of microorganisms such as bacteria and the like in the water tank are propagated, and the water quality is polluted. The phenomenon that the quality of tap water exceeds the standard due to the secondary pollution, particularly the phenomenon that microorganisms exceed the standard, is one of the main reasons for the water quality of tap water supply not reaching the standard at present.

Several conditions are common that lead to microbial production: 1. the exhaust process of the exhaust valve can cause water to contact with air to generate microorganisms, 2, the flow in the pipeline is uneven, water points are used for opening and sucking air to cause air to contact with the microorganisms, and 3, the manhole maintenance of the water tank can cause air to contact with water to cause microorganism generation.
