Abstract
In the upstream and nearby areas of the water source, there are many areas where the sewerage penetration rate is relatively low due to development restrictions. This has been continuously affecting the pollution of the water source. As a measure to prevent this, method of distributing sewage and improving existing facilities are suggested. In this study, A MWTP(Municipal Watewater Treatment Plant) using the Air-vent SBR process located at upstream of An-dong and Im-ha Dam was selected as a modeling facility. And, the retrofit method to improve the effluent from RCSTP(Rural Community Sewage Tratment Plant) was induced based on A MWTP modeling result. The model construction and verification were carried out based on the operating data for 5 years (2012 ~ 2016). As a result, it was analyzed that the water quality of the effluent during the winter could be improved through control of cycle time in Air-vent SBR process and decreasing SRT (BOD: 1.8%, COD: 54.5%, SS: 4.3%, T-N; 0.8% and T-P: 7.7%). This research suggests that result of this research can be utilized as a retrofit method to improve the effluent overall treatment efficiency of the MWTP and the RCSTP which have similar operation process.
