축산폐수 처리 중 첨가제에 의한 악취성분의 변화 측정

Abstract

FIA provides and supports high quality and production analysis and control systems for on-site water analysis and on-line monitoring for wastewater treatment. So FIA has been developed with a high quality multichannel peristaltic pump, an injection valve, a coiled reactor, and a detector such as a photometric flow cell. The analytic principle of phosphate is the colorimetric method by ascorbic acid at 690 nm of wavelength. The optimum operating conditions of FIA was observed 30 μL of sample injection volume, 2.25 mL/min. of flow rate, 80 cm of reaction coil and 20oC of reaction temperature. Comparison with manual korean standard method was carried out to evaluate the accuracy and precision of FIA. As a result, good agreement and possibility for application to on-line monitoring of wastewater treatment process was examined.
