하수처리장 통합모델 (Pukyong plant-wide model No.1)에 관한 연구

Abstract

A present existing modelling of wastewater treatment plant mainly has constituted sewage treatment process modelling.. Under these modelling, there were a great gap between the results of modelling and real operation due to excluding the sludge loading. Therefore, for easy-application of the field, it is desirable to develop optimal model which integrated activated sludge and anaerobic digestion model. This study present the results of the work carried out PKPWM1 (PuKyong Plant Wide Model No.1). This model is based on a new concept for dynamic simulation of wastewater treatment plants. The methodology is based on biological treatment. A sensitivity analysis was performed to determine the key parameters of the model. Results of this study are, 1. This study present Peterson's matrix of PKPWM1 that is not existing the ASM and the ADM simple connection and intergrated and not complex. 2. Regrssion model is presented by using multi regression method physical model like settling tank and thickener tank. 3. Thks study present aqusim program that modelling whole process in WWTP. In this aquasim program have a convenience that can simulate a variety of biological nitrogen remove processes such as conventional activated sludge, MLE, A2O, A/O, UCT, VIP process and ease. 4. PKPWM1 of parameter sensitivity analysis as a priority bH, μH, μA chose 18 parameters, such as the 2006 Southern Sewage Treatment Plant material parameters were estimated. The BOD measured value and the calculated value of the degree of error, RMSE is 4 mg / L, COD is 1.4 mg / L, SS is 1.1 mg / L, TN is 2.2 mg / L and TP is 0.28 mg / L. Results of the 2007 simulation ​​were similar to 2006 RMSE.
