Abstract: The landfill leachate treatment project has been designed with combined processes, which consists of coagulation and ammonia-nitrogen stripping, UBF anaerobic process and two stages of Anoxic/Oxic process, filter, UF and RO deep treatment. The outlet water would meet the standard shown in the table 3 in the “Standard for Pollution Control on the Landfill Site of Municipal Solid Waste” (GB16889-2008). After the project had been completely finished, the commissioning was going on. After 85 days, the results showed that the outlet water was 100m3/d, its COD was about 20mg/L, and the ammonia-nitrogen was below 8mg/L. [Copyright &y& Elsevier]
