Tap water refers to the water purified and disinfected by the tap water treatment plant, which meets the corresponding standards and is used for people's life and production.

Domestic water is mainly extracted from rivers, lakes, groundwater and surface water through the water intake pumping station of waterworks. According to the national sanitary standard for drinking water, the waterworks are treated by sedimentation, disinfection, filtration and other processes, and finally delivered to various users through the water distribution pump station.

Chlorination method is often used for disinfection of tap water. The main purpose of chlorination of public water supply is to prevent water-borne diseases. This method has been popularized for more than 100 years, and it has relatively perfect production technology and equipment. Chlorine used for disinfection of tap water 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 chlorine still has some disadvantages in disinfection of tap water. After chlorination and disinfection, tap water will produce carcinogens, and relevant experts have also put forward many improvement measures.
