| description | To provide a water quality measurement method for treated water, a water quality control method for the treated water, a water quality measurement apparatus for the treated water, and a water quality control system for the treated water, capable of measuring an alkalinity of the treated water quickly and reliably with a simpler system and enable continuous monitoring.SOLUTION: A water quality measurement method for treated water has a step of setting an acid injection rate at which a pH value of the treated water becomes 4.8 or lower, determining an electrical conductivity ECH of the treated water corresponding to the set acid injection rate, injecting acid into the treated water at the acid injection rate, measuring an electrical conductivity EC0 of the treated water before acid injection and an electrical conductivity EC1 of the treated water after acid injection, and calculating an alkalinity of the treated water based on measurement results of the electrical conductivity EC0 and the electrical conductivity EC1, and the electrical conductivity ECH.SELECTED DRAWING: Figure 1
【課題】被処理水中のアルカリ度をより簡単なシステムで迅速かつ確実に測定でき、連続的なモニタリングが可能な被処理水の水質測定方法、被処理水の水質制御方法、被処理水の水質測定装置、及び被処理水の水質制御システムを提供する。【解決手段】被処理水のｐＨ値が４．８以下となる酸注入率を設定し、設定した酸注入率に相当する被処理水の電気伝導率ＥＣHを決定し、被処理水に上記酸注入率で酸を注入し、酸注入前の被処理水の電気伝導率ＥＣ0及び酸注入後の被処理水の電気伝導率ＥＣ1を測定し、電気伝導率ＥＣ0、電気伝導率ＥＣ1の測定結果及び電気伝導率ＥＣHの値に基づいて、被処理水のアルカリ度を算出する工程を有する被処理水の水質測定方法である。【選択図】図１ |
