VARIATIONS OF LANDFILL LEACHATE'S PROPERTIES IN CONJUNCTION WITH THE TREATMENT PROCESS

摘要

A study was done on the variations of water quality parameters, in conjunction with the processing steps, installed for the treatment of leachate form a sanitary landfill. The leachate was primarily subjected to biological treatment, composed of anaerobic digestion, aerobic treatment, and rotating biological contact in series. The effluent form the rotating biological contact process was further treated by combination of flocculation-sedimentation and adsorption processes. Finally it was polished by the reverse osmosis process before discharge. The quality of raw leachate, of influents to and of effluents from the reverse osmosis process was assessed and compared.
