Title:
水処理システムにおける水中の有機物評価方法及び水処理システム
Document Type and Number:
Japanese Patent JP6719292
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an evaluation method enabling a content of an organic matter in water, in particular, controversial humus and surfactants and the like in water in a water treatment system to be easily obtained in a short period of time, and a water treatment system to which the evaluation method is applied.SOLUTION: A method for evaluating an organic matter included in water in a water treatment system is provided that has: a step of preparing from water, a plurality of samples having different concentration of organic carbon, the concentration of the organic carbon being measured by an organic carbon measurement method; a step of measuring the plurality of samples by a fluorometry thereby acquiring fluorescence intensity of a specific organic matter in each organic carbon concentration; and a step of acquiring a calibration curve from the fluorescence intensity in each organic carbon concentration of the specific organic matter and each organic carbon concentration. The method is configured to measure fluorescence intensity of the specific organic matter in water by the fluorography to identify the specific organic matter in the water, and estimate whole organic carbon concentration in the water from the fluorescence intensity, based on the calibration curve.SELECTED DRAWING: Figure 6
