摘要: Relatively “old” (stabilized) landfill leachates are a special category of wastewaters, which difficult to treat further, mainly due their bio-refractory organic content (humic substances). In this study, coagulation—flocculation was examined as post-treatment method for the biologically pre-treated stabilized leachates. The purpose examine coagulation performance alternative coagulant agents, i.e. composite polyaluminium silicate chloride. Composite coagulants with different properties were prepared and characterized by means aluminium species distribution, pH turbidity. Their efficiency evaluated monitoring turbidity parameters strongly correlated presence matter, such UV absorbance at 254 nm, COD color.
