A comprehensive mathematical model has been revised to estimate greenhouse gas (GHG) emissions by urban wastewater treatment plants (WWTP) resulting from on-site activities. The contribution of individual processes and well-management levels of WWTPs to the production of GHGs in hybrid treatment system has been determined. Using the revised mathematical model, we estimate the total CO 2 equivalent mass and per unit COD removal mass of emission in Dalian City from year 2004 to 2013. According to
more » ... the results, our prediction is that the overall CO 2 equivalent mass of emission will continue to increase, but improvement of wastewater treatment technology and automatic detection can efficiently reduce the growth. The revised emission factor of GHG emissions from nutrient removal in the overall GHG emissions of WWTPs increased the accuracy and completeness of this estimation, lending support to the novelty of the present study.
