CO2 Emission on the Process of Sewage Treatment during "11th Five-Year Plan" Period

Abstract

China established a national level of principle pollutions emission that 10 percent reduction of SO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> and COD discharges by priority projects, structural adjustment, and environmental management during the "11 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> Five-Year plan" period. This paper focused on the induced effect to CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> emission on the process of urban sewage treatment. CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> emission related to two parts of treatment process: municipal wastewater treatment plant construction and operation. Energy consumption play an important role when calculate CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> emission on the process of urban sewage treatment construction and operation by using input-output model. It came up with that 30.95 tons CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> emission when reduce 1ton COD on average during the "11 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> Five-Year plan" period.
