The revision of the "Hygienic Standard for Drinking Water" is one of the important measures to ensure drinking water. Under the coordination of the Standardization Administration of the People's Republic of China, the Ministry of Health took the lead and, in collaboration with the Ministry of Construction, the Ministry of Land and Resources, the Ministry of Water Resources, and the State Environmental Protection Administration, organized various sectors including health, water supply, environmental protection, water conservancy, and water resources to jointly participate in the revision of this standard.

　　　The new standard has the following three characteristics:

　　First, it has strengthened the requirements for organic matter, microorganisms and water quality in water. The drinking water quality indicators in the new standard are the same as those in the original standard35Xiang Zeng106The items have been increased71Item. Among them, the microbial indicators are composed of2Xiang Zeng6Item; The indicators of drinking water agents are1Xiang Zeng4Item; Inorganic compounds in toxicological indicators are composed of10Xiang Zeng21Item; Organic compounds in toxicological indicators are composed of5Xiang Zeng53Item; Sensory properties and general physicochemical indicators are determined by15Xiang Zeng20Item; The radioactive index remains2Item.

　　1Sensory traits

　　It is through our naked eyes to observe whether there are impurities in the water. The color regulation for drinking purified water is within5The degree of turbidity is set at0.5ntuThere is no unpleasant smell, stench or any substance that cannot be observed with the naked eye.

　　2Chemical indicators

　　The water quality of drinking purified waterphThe value standard is6.0-8.5The total hardness is300mg/LThe contents of iron, manganese, zinc and aluminium are respectively:0.20,0.05,1.0,1.0,0.20mg/LThe volatile substances: phenols, anions, oxides, sulfates, total dissolved solids, and potassium permanganate consumption are respectively:0.002,0.20,100,250,500,2mg/LThe indicators.

　　Second, it has unified the hygiene standards for drinking water in both urban and rural areas.

　　Third, it is to achieve the alignment of drinking water standards. The selection of new standard water quality items and index values fully takes into account the actual situation in China and refers to the World Health Organization's "Guidelines for Drinking Water Quality", as well as the drinking water standards of the European Union, the United States, Russia and Japan.

　　Scope of application

　　This standard specifies the hygiene requirements for the quality of drinking water, the hygiene requirements for the quality of drinking water sources, the hygiene requirements for centralized water supply units, the hygiene requirements for secondary water supply, the hygiene requirements for products related to the hygiene of drinking water, as well as the methods for water quality monitoring and water quality testing. This standard is applicable to drinking water for all types of centralized water supply in urban and rural areas, as well as to drinking water for decentralized water supply.

　　Hygiene requirements for products related to drinking water for daily use8.1 Flocculation, coagulation assistance, oxidation and adsorption adopted for the treatment of domestic drinking waterpHChemical treatment agents such as those for regulation, rust prevention and scale inhibition should not contaminate drinking water and should comply with the requirementsGB/T 17218Requirements.8.2The water distribution equipment, protective materials and water treatment materials for domestic drinking water should not contaminate domestic drinking water and should comply withGB/T 17219Requirements.

　　The above is a summary by Beijing Yuanlai Company of some content about the "Water quality standards for drinking Purified Water". We hope everyone has gained some understanding of this. Beijing Yuanlai Water Treatment Equipment Co., Ltd. has always adhered to the Yuanlai philosophy of "customer first, everything for users, solving users' problems".
