DEVELOPMENT OF SUSTAINABLE WATER TREATMENT AND WATER QUALITY CONTROL SYSTEMS: LEACHATE TREATMENT FROM MUNICIPAL SOLID WASTE AND INDUSTRY LANDFILLS = DEVELOPMENT OF SUSTAINABLE WATER TREATMENT AND WATER QUALITY CONTROL SYSTEMS: LEACHATE TREATMENT FROM MUNICIPAL SOLID WASTE AND INDUSTRY LANDFILLS

다국어 초록 (Multilingual Abstract)

For accurate evaluation of treatment methods, it is crucial to obtain precise analytical methods for leachate. Only then is it possible to design and construct proper treatment methods. Experiences from four leachate treatment plants in Sweden have been gathered, with respect to the characterization of the efficiency of leachate treatment methods, considering different groups of pollutants, such as phenolic compounds, PCBs, PBDEs, and phthalates. Since leachate water samples contain many different compounds, identification of all the substances is an unrealistic aim. Therefore, it is better to study the improvements after a treatment procedure by measuring the total detected signal from groups of substances having similar properties. Acute and chronic toxicity tests using appropriate biological methods and the choice of organisms are presented, in addition to the LAQUA protocol used at the pilot plant in Kristianstad, Sweden. In acute toxicity tests of the leachate, a clear relationship between the immobility of Artemia larvae and increasing concentration of leachate was noted. This work is a first step to obtain knowledge to create tools for the construction of treatment plants for municipal solid waste and industrial waste leachate that will fulfil future demands with respect to environmental pollution.
