Abstract
According to the characteristics of the landfill leachate,the combined process of anaerobic baffled reactor,primary aerobic treatment,contact anaerobic treatment,secondary aerobic treatment,Fenton oxidation and biological aerated filter was used.COD and ammonia nitrogen in the raw wastewater were about 1 300 mg/L and 300 mg/L respectively.The operation results show that the operation of the combined process is stable.The removal rates of COD and ammonia nitrogen are 93% and 98% respectively.The effluent COD,ammonia nitrogen,color and SS are less than 100 mg/L,25 mg/L,40 times and 30 mg/L respectively,which meet the table 2 criteria specified in Standard for Pollution Control on the Landfill Site for Domestic Waste(GB 16889-2008).
