Features: This book is a detailed technical manual for sudden pollution incidents in the urban water supply industry. It categorizes 135 water quality indicators that may exceed standards during sudden pollution incidents in urban water supply into three parts: 99 items specified in the "Sanitary Standard for Drinking Water" (GB5749-) (Draft for Approval), 5 items specifically included in the "Standard for Water Quality of Urban Water Supply" (GJ/T206-2005), and 31 items specified in the "Standard for Environmental Quality of Surface Water" (GB3838-2002). Additionally, 31 items specified in the "Standard for Environmental Quality of Surface Water" (GB3838-2002). Each part is divided into five major categories based on pollutant types: inorganic pollution, organic pollution, microbial pollution, radioactive pollution, and algal and algal toxin pollution. This manual provides detailed and comprehensive information on each water quality indicator for issues that need to be addressed in urban water supply emergency work, including substance identification, physicochemical properties, environmental behavior, toxicological characteristics, and reference values in domestic and international water quality standards. The substance identification includes chemical name, alias, English name, CAS number, molecular formula, and molecular weight. Physicochemical properties include appearance and state, melting point, boiling point, density, vapor pressure, and solubility. Domestic and international water quality standards include the new "Sanitary Standard for Drinking Water" (GB5749-) (Draft for Approval), the "Sanitary Norms for Drinking Water" (2001), the "Standard for Water Quality of Urban Water Supply" (CJ/T206-2005), the "Standard for Environmental Quality of Surface Water" (GB3838-2002), and the new drinking water standards from the World Health Organization, the United States, the European Union, and Japan. At the end of each water quality indicator in this manual, the emergency treatment measures for water pollution of that item are provided, including emergency treatment methods, dosage estimation of chemicals to be added, and other relevant information. The content of this manual is of significant guidance value for the relevant work in the urban water supply industry, especially for decision-making in handling sudden pollution incidents, and provides a certain reference value for researchers and learners in this field.
