DEVICE FOR MESURING BIOCHEMICAL OXYGEN DEMAND

摘要

PURPOSE: A biochemical oxygen demand (BOD) measuring device is provided to quickly measure BOD through quantitative/qualitative analysis of organic materials. CONSTITUTION: A BOD measuring device comprises: a water quality variable measuring unit (100) for measuring water quality variable; a generation unit (120) for generating BOD measurement interaction equation; a storage unit (130) for storing the interaction equation; and a BOD measuring unit (140) for measuring BOD using the water quality variable and the interaction equation. The interaction equation is generated from correlation between BOD and one among dissolved organic carbon (DOC), conductivity, fluorescence characteristics, and UV absorbance by regression analysis.
