Title
Correlativity of Organic Carbon Indices for Influent and Effluent of Sewage and Wastewater Treatment Plant
임경호Kyeong Ho Lim,김광수Kwang Soo Kim
Abstract
In this study, correlations between COD_Cr, COD_Mn and BOD of samples from domestic and industrial wastewater treatment plants were investigated to set up the basic guideline for altering the index of organic matter content from COD_Mn to COD_Cr. In the case of domestic wastewater, BOD was more favorable for the estimation of organic matter content than COD_Mn and COD_Cr because microbial products which had no harmful effect on the environment, were counted as organic pollutant during COD test. However, in the case of industrial wastewater, COD_Mn and COD_Cr were suitable because organic and inorganic toxic pollutants inhibited microbial respiration during BOD test. It could be suggested that COD_Cr became meaningful after the installation of advanced treatment processes such as activated carbon in the industrial wastewater treatment plant.
