Tap water comes uninvited.
Water is the source of life, and our life.closeRelated, turn on the tap,Tap water flows out slowly. While enjoying the convenience brought by modern life, have we ever wondered where these tap water comes from? What technological processes have you gone through to reach thousands of households? today,We walked into Beihai main water supply plant.—— North Suburb Water Plant, visit the surface water purification process, and learn about the "past lives" of tap water together.

The Northern Suburb Water Plant adopts surface water technology, and the water source is Niuweiling Reservoir. The design daily water supply capacity of Phase I is as follows150,000 tons. The northern suburb water plant started construction in 1993, and was shut down in 1996 due to the influence of national macro-control. In 2009, our company invested 65 million yuan to start the continuation project of the northern suburb water plant. In October 2011, the construction of the continuation project was completed. However, due to the serious eutrophication of the water source of Niuweiling Reservoir, the water after conventional treatment has a heavy muddy smell and it has been transformed into an underground water plant. In 2017, in order to effectively alleviate the shortage of water supply in our city, the water quality upgrading project of Beijiao Waterworks was started. Pretreatment and advanced treatment processes were adopted for the eutrophic raw water of Niuweiling Reservoir. The project was completed in December 2018, with a total investment of 97.8362 million yuan, and was officially put into production on January 7, 2019. In order to further improve the security of urban water supply, the company started construction of the second phase of Beijiao Water Plant in September 2020 according to the requirements of the municipal party committee and the municipal government, and it is expected to be completed in December 2022. The total investment of the project is 323 million yuan. In the past 12 years since 2009, our company has invested about 486 million yuan to improve the quality of drinking water in our city and ensure the safety of urban water supply.

There are many microorganisms, protozoa, viruses and pathogenic bacteria in natural water. In order to prevent pathogenic bacteria from bringing diseases to people, water supply companies will adopt disinfectants such as liquid chlorine or chlorine dioxide to disinfect and kill microorganisms and pathogenic bacteria in water.
Chlorine dioxide and liquid chlorine used by our company for disinfection are effectively controlled in strict accordance with the national Hygienic Standard for Drinking Water in the production process. The limit value of chlorine dioxide in the factory water using chlorine dioxide disinfection process is as follows0.1-0.8mg/L, the pipe network water limit value is greater than 0.02mg/L, the residual chlorine limit value of the factory water by liquid chlorine disinfection process is 0.3-4mg/L, and the pipe network water limit value is greater than 0.05 mg/L.
Users smell the smell in the process of use because people’s taste threshold for chlorine is0.2-0.5mg/L, when the chlorine in water exceeds 0.2mg/L, people can smell chlorine, but it is within the national standard value, which is qualified and safe drinking water, and users can use it with confidence.
