Abstract：Due to the increase wastewater discharge with the rapid economic development, it is desired to achieve the energy conservation and emission reduction of sewage treatment. In addition, realization of the relationship between COD removal and CO2-emission is valuable for improving the COD removal rate and reducing the CO2-emission in the sewage treatment system. In this study, an optimization model for sewage treatment planning is developed for pollutants control and CO2-mitigation emission in sewage treatment system. The optimized sewage-allocation scheme would be generated through the proposed model with the objective of minimized system operation cost. Based on the analysis of COD discharge standard and CO2-emission constraints, the adjustment plans for sewage plant operation would also be obtained, achieving both economic and environmental benefits simultaneously. When COD discharge standard is second, first B, first A, the amount of CO2 emission would be 13408.74, 15304.47, 15900.81t/a, respectively. The results demonstrate that willingness to meet higher COD emission standard would be related to higher COD removal rate and CO2 emission.
