- Abstract:
- Taking the treatment project of landfill leachate membrane concentrate in Guangdong Province as a case, the design parameters, operating effects and operation cost based on a mechanical vapor recompression (MVR) evaporation system are introduced. The application results show that the landfill leachate membrane concentrate is reduced by over 85% in weight. The average removal rates of chemical oxygen demand (COD) and ammonia-nitrogen (NH3-N) are 99.86% and 99.95%, respectively. The effluent indexes of the landfill site meet the special discharge limits of water pollutants in table 3 of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008). The operation cost for the MVR evaporating system is 86.87 yuan/m3. It brought considerable economic benefits for the landfill site by implementing this system, which would save 7.90 million yuan annually.
