cod-8とは 意味・読み方・使い方

A spectrophotometer built-in with a program of an operation expression [expresssion (8)] for the COD based on absorbance reduction, and capable of digital-displaying an operation result is used to allow direct reading of a COD value.例文帳に追加

また、吸光度減少に基づくＣＯＤの演算式［（８）式］のプログラムを内蔵し、演算結果をディジタル表示できる分光光度計を用いることによってＣＯＤ値を直読可能とする。 - 特許庁

A measurement value from the UV meter 6 is converted from BOD to COD by using correctional equations 7, 9 respectively stored in a BOD conversion means 8 and a COD conversion means 10 of an arithmetic unit 12, and further converted into a model component input value by a COD model component input value conversion means 13.例文帳に追加

ＵＶ計６からの計測値は演算手段１２のＢＯＤ変換手段８およびＣＯＤ変換手段１０に各々内蔵された相関式７，９を用いてＢＯＤからＣＯＤに変換され、さらにＣＯＤモデル成分入力値変換手段１３によってモデル成分入力値に変換される。 - 特許庁

After waste water containing COD component is brought into contact with an oxidizing agent such as sodium hypochlorite, an alkaline material such as sodium hydroxide is added to adjust pH not less than 8, preferably not less than 10, and then the waste water from which the COD component is highly eliminated is obtained by bringing into contact with a strongly basic negative ion exchange resin or by ion-exchange treatment by performing electrodialysis.例文帳に追加

ＣＯＤ成分を含有する排水を次亜塩素酸ソーダの如き酸化剤と接触せしめた後、苛性ソーダなどのアルカリ物質を添加してｐＨを８以上、好ましくは１０以上に調整し、次いで、強塩基性の陰イオン交換樹脂との接触、或いは、電気透析の実施等によるイオン交換処理を行うことにより、ＣＯＤ成分が高度に除去された排水を得る。 - 特許庁

A flowmeter 7, a COD meter 8 and a coli bacteria sensor 9 are provided at supply piping 3 for supplying the sewage (water to be treated) to an ozone reactor 2, and an ozone injection ratio of the ozone injected to the ozone reactor 2 (ozone quantity required for a unit amount of the water to be treated) is decided based on the measured value.例文帳に追加

下水（被処理水）をオゾン反応槽２に供給する供給配管３に流量計７、ＣＯＤ計８、大腸菌センサ９を設け、この測定値に基づいてオゾン反応槽２に注入するオゾンのオゾン注入率（単位被処理水量当たりに必要なオゾン量）を決める。 - 特許庁
