GB/T 19837-2019Ultraviolet (UV) disinfection equipment for urban water and wastewater engineering (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 19837-2005 "Urban UV disinfection equipment for water supply and drainage". This standard is in line with GB/T 19837-2005 In addition to editorial changes, the main technical content changes are as follows.

--- Revised "Scope" (see Chapter 1, Chapter 1 of the 2005 edition);

--- Modified "terms and definitions" (see Chapter 3, Chapter 3 of the 2005 edition);

--- Modified "classification and composition" (see Chapter 4, Chapter 4 of the 2005 edition);

--- Modified the "packaging" requirements (see 8.2.2, 8.2.3, 8.2.4, Chapter 1 of the 2005 edition);

--- Modified the "Test Method for UV Lamp Life and Aging Coefficient" (see Appendix A, Appendix A of the 2005 edition);

--- Modified the "Method for Detecting the Scaling Coefficient of Ultraviolet Lamp Sleeve" to stipulate by referring to Appendix B in GB/T 32091-2015 (see 6.3, (Appendix B of the 2005 edition);

--- Modified the ultraviolet effective dose and average dose detection methods, and explicitly adopted the quasi-parallel light detection method to quote

GB/T 32091 specifies Appendix E (see 6.5, Appendix C and Appendix D of the 2005 edition);

--- Deleted the "design requirements for ultraviolet disinfection equipment" (see Appendix E of the 2005 edition).
