Research of leachate treatability with b

One of the disposal methods of household wastes is landfill. In our country, 1 kg per person and totally 30 million tons household waste per day is produced. It is the responsibility of the municipalities to carry out collection and disposal of household wastes and there are 79 landfill areas present in our country. In terms of environment pollution, the most important subject is treatment of leachate at landfills. Leachate consists many of pollutants that arise from the contents of the household waste is formed with biological reactions when landfilling, water content of the waste and rain water coming from outside environment to the storage site. Collection and treatment of leachate is important due to its content of high amount organic substances, nitrogenous compounds, heavy metals, aromatic chorionic and inorganic salts and its potential to cause pollution to soil and underground waters. The characteristics and quantity of leachate varies for each landfill and depend on content of household waste, climate conditions, structural design of landfill area, structure of surface cover and operation properties. Leachate is the most difficult waste water for treatment because of high contaminant properties. In this respect, generally, a combination of physical, chemical, biological methods and adsorption and membrane technologies from advanced treatment methods are used for leachate treatment. In this study, IZAYDAŞ Solid Waste Landfill Area where Kocaeli province's solid waste is stored, leachate treatability with biological-chemical and submerged MBR process is utilized and compared with full scale MBR Treatment Plant treatment efficiency and all these have been evaluated.
