氨氮水质自动分析仪新旧标准的变化与探讨

Changes and Discussion on the New and Old Standards of Water Quality Automatic Analyzers for Ammonia

原氨氮水质自动分析仪技术要求(HJ/T101-2003)已实施长达15年,如今已不能适应水质氨氮自动监测行业的发展。新修订的氨氮水质在线自动监测仪技术要求及监测方法(HJ 101-2019)于2020年开始实施,其内容相比于原标准做了大量的修改。从应用范围及仪器量程、性能指标、仪器构造和其他等方面将原标准与新标准进行了比较,结果表明:氨氮自动分析仪具有使用范围更广、技术要求更严格、自动化程度更高、模块化以及维护便利化等发展趋势。

The technical requirements for water quality automatic analyzer of ammonia(HJ/T101-2003)have been implemented for 15 years,and now it cannot meet the development of water quality automatic analyzer industry.The newly revised technical requirements and monitoring methods of ammonia nitrogen water quality online automatic monitor(HJ 101-2019)was implemented in 2020,and its content has made a lot of changes compared to the former standard.This paper compares the former standard and the new standard from the scope of application,instrument range,performance index,instrument structure,and other aspects.It also summarized the development trend of ammonia automatic analyzer with wider application range,stricter technical indicators and higher degree of automation,modularization and facilitation of maintenance.
