Modelagem matemática para avaliação dos efeitos de despejos orgânicos nas condições sanitárias de águas ambientais

摘要: This article provides an overview of emerging trends in environmental approaches to wastewater management the developing world. Organic matter present is one main sources water pollution. In large amounts it can increase number microorganisms and thus excessive consumption dissolved oxygen metabolic processes its utilization stabilization, leading disappearance extinction aerobic organisms, favoring appearance other life forms anaerobic conditions, often producing toxic residues. The focus this analyze presence organic urban sewage using a quality model whose parameters are biochemical demand. Wastewater methodologies contribute public health, sanitation, improved conservation resources.
