| Abstract |
| This study, subject to influent and effluent of public sewerage facilities in Gwangju city, is to comprehend the behavior of TOC, analyze the correlations with organic materials. As the influent flows into sewerage facilities, each average concentration was TOC 55.8 mg/L, DOC 34.9 mg/L, BOD 132.4 mg/L, CODMn 62.1mg/L and the item's average concentrations of the effluent was TOC 9.6 mg/L, DOC 6.9 mg/L, BOD 4.8 mg/L, CODMn 9.0mg/L respectively. The concentration of DOC indicated higher than POC from both the influent and effluent; thereby demonstrating the concentration of dissolved organic materials was contributing more to the concentration of TOC. The oxidization rate of C-BOD/TOC 96.3% in influent, 13.3% in effluent showed large deviation with having variation based upon the size of sewerage facilities. Whereas the oxidization rate of CODMn/TCO 42.5% in influent, 36.2% in effluent did not deviate as much, in regards to the size of sewerage facilities. As the correlation coefficient value with TOC, a large-size sewerage facility was BOD 0.657 (p<0.01), CODMn 0.631 (p<0.01), CODCr 0.571 (p<0.01) and a small-size sewerage facility was CODMn 0.765 (p<0.01) in influent. A large-size sewerage facility showed relativity of TOC with CODMn 0.751 (p<0.01) and a small-size sewerage facility indicated a close correlation with BOD 0.921 (p<0.01), CODMn 0.834 (p<0.01), CODCr 0.0.786 (p<0.01) in effluent respectively. |
