Demonstration and Research on Landfill Leachate Treatment by the Process of Mineralized Refuse Bed and SBR

According to demonstration, the process of mineralized refuse bed and SBR for landfill leachate treatment is selected. As CODcr of two leachate is 22 648 and 13 236*!g/L, and NH 3-N of two leacate is 850 and 642*!mg/L respectively, a good treatment effect is gotten. The experimental results show,after treatment, the CODcr of leachate can be lower than 300*!mg/L, and NH 3-N of leachate can be lower than 20*!mg/L, and the quality of leachate can fulfill the second discharge standards.
