Scope

This standard applies to the effluent from water purification equipment used in urban and rural centralized and decentralized water supply systems, as well as packaged drinking water, etc. Main technical contents: 1. Healthy drinking water: On the basis of meeting the requirements of the national standard "Hygienic Standards for Drinking Water" GB5749, it further removes substances harmful to human health and retains the original and balanced nutrients and essential trace mineral elements in water, which is used for people's daily drinking and living. 2. Total dissolved solids (TDS): It refers to the total amount of all dissolved substances in water, including the contents of both inorganic and organic substances. 3. Centralized water supply: A water supply method in which water is collected from a centralized water source and delivered to users or public water-drawing points through a water distribution network, including water supply from built facilities. Water supply stations providing daily drinking water for users and water supply with different quality for public places and residential areas also belong to centralized water supply. 4. Decentralized water supply: A water supply method in which households directly draw water from water sources without any facilities or with only simple facilities.
