Landfarming for Treatment and Disposal of Oily Wastes Originating in the South Petrochemical Complex

摘要: Landfarming, a waste treatment system using biological degradation, has been very successfully used for the decomposition of oily sludges. This paper presents data on project recently developed by COPESUL (Companhia Petroquimica do Sul) implementation this as solution disposal The characteristics are different to those other projects already operating in Brazil. It was due experience these that some modifications were introduced project. site chosen divided into six parallel cells provided with internal roads allow easy access equipment. made impermeable means structure composed, from bottom top, of: layer unsaturated natural clay minimum thickness 3.60 m (with top 15 cm compacted); draining ballast, safety purposes, which collects liquid if percolates through layer; an 50 cm, obtained compaction local clay; and reactive layer, properly prepared receive sludge. is also tanks be treated storage rainwater leachate collected transported SITEL (Integrated System Treatment Liquid Effluents) treatment. Furthermore, area drums wastes delivered form. In addition project, gives details wastes, monitoring plan, investment costs, data.
