BOD-Q水质测定仪的研制及其实验教学应用
Development of the BOD-Q Water Quality Analyzer and Its Application in Laboratory Teaching
摘要
Abstract
Biochemical oxygen demand(BOD)is a critical indicator in scientific research related to water pollution control.The traditional BOD testing method,based on dissolved oxygen consumption,has several disadvantages,including a long testing period,significant errors,poor reproducibility,and complex procedures,which hinder the advancement of water environment and ecology research as well as its application in experimental teaching.This paper presents a new principle,method,and instrument for BOD detection,detailing the development of an innovative scientific instrument—the"BOD-Q Water Quality Analyzer"—and its application in laboratory teaching.The results indicate that this instrument reduces the BOD detection time from the conventional 5 days to just 0.5 to 5 hours,with a detection error of less than 10%.Integrating this instrument into laboratory teaching enriches the curriculum and enhances teaching quality.关键词
