A BRIEF METHOD TO SIMULATE AND OPTIMIZE CURVE OF REDUCTION OF COD FOR LANDFILL LEACHATE

YANG Jun~(1,2),HUANG Tao~1,YANG Li-zhong~1 (1.School of Environmental Science and Enginnering, Southwest Jiaotong University, Chengdu610031, China; 2.Lanzhou Jiaotong University, Lanzhou730070, China)  
In this paper, a mathematical model of reduction of COD for landfill leachate is proposed, which based on the data of COD of Laogang landfill in Shanghai. The realizable method using Excel software to simulate and optimize the curve equation is introduced. the result shows: ①the course of reduction of COD for landfill leachate accord with the fist order reactor equation.②the method is proved to be brief and clear, and the precision is also very much high. It is worth being applied to engineering.
