廃水分析値のユーザー定義単位(mg/L)について

YuiKawa

お世話になっております

現在、BODやCODなどの廃水分析値用の単位(mg/L)をユーザー定義単位で作成しようとしています

参照システム定義単位をg/Lにし、0.001の係数をかける必要がある認識です

 

一方、g/LはDensityクラスに所属していますが、今回のBODやCODのmg/LはDensityとは別の意味になります

このような場合、どのように設定すればよろしいでしょうか？教えてください

 

※BODやCODで使用されているmg/Lは、水中の微生物が有機物を分解するために、１Lあたりに必要な酸素量を示している

    Regarding user-defined units (mg/L) for wastewater analysis values

    I am currently trying to create a user-defined unit (mg/L) for wastewater analysis values ​​such as BOD and COD

    I understand that the reference system-defined unit should be g/L and multiplied by a coefficient of 0.001

    On the other hand, g/L belongs to the Density class, but the mg/L of BOD and COD in this case has a different meaning from Density

    How should I set it in this case? Please let me know

     

    *The mg/L used in BOD and COD indicates the amount of oxygen required per liter for microorganisms in the water to decompose organic matter
