碩士 === 國立中興大學 === 環境工程學系所 === 98 === This study tried to establish the relationship between visual transparency and COD, BOD, as well as SS concentrations in the effluent of various industrial wastewater treatment plants, This study also tried to understand the feasibility of estimation of effluent BOD, COD, and SS concentrations with the visual transparency method. Because the measurement of BOD, COD, and SS concentrations must employ analytic instruments, these analytic procedures are time-consuming practices. Thus, if the sample can be rapidly detected by transparency method, not only the analytic time but also the analytic chemicals, such as solvents and acidic solution, can be saved. This study employed the analytic results of the COD, BOD, SS analysis and transparency measures of COD, BOD and SS water samples to establish their relationships. The results of this study indicated that the visual transparency could be used to estimate the effluent BOD, COD, and SS concentrations for the effluent of slaughter industry, domestic wastewaters treatment plants, and hospital wastewater.
