| Abstract: | The basic components of leachate and its treatment method were simply introduced.The thermal process of mechanical vapor compression leachate was emphatically analyzed,and the corresponding mathematical model was established according to the equations of mass and energy.The relationships between leachate inlet temperature and heat exchanger area,evaporation ratio and evaporation area as well as the compression ratio were illustrated.The results show that the environmental temperature rise is beneficial to reducing the investment cost of the mechanical vapor compression system.Enhancing the evaporation ratio needs to increase the corresponding compressor power,thus improving the system operation cost. |
