Abstract

MéTODO DE TRATAMENTO DE áGUA E COMBINAçãO INTEGRANDO UM TRATAMENTO BIOLóGICO FIXO E DECANTAçãO POR FLOCULAçãO. Trata-se de um método inventivo de tratamento de água e disposição que combina sucessivamente pelo menos uma etapa consistindo no tratamento biológico de pelo menos uma parte de poluição contida nas ditas águas por uma biomassa fixa, onde um fluxo biologicamente limpo que pode ser obtido logicamente no final da dita etapa, antes da entrada do mesmo em uma próxima etapa, contém menos de 2 g/l de MES, e pelo menos um estágio para realizar uma decantação por floculação por meio de flocos estabilizados consistindo na transferência do fluxo tratado biologicamente para uma área de mistura (2), preferivelmente em uma gradiente de velocidade variando de 10^ S-1^ a 1000^ S-1^, onde é injetado pelo menos um tipo de material granulado insolúvel mais denso do que água e substâncias suspensas são agregadas em volta das ditas partículas de material granular, na transferência do fluxo emitido da área de mistura (2) para uma área de decantação, onde o fluxo purificado e os sedimentos de decantação misturados com o material granulado são separados, na extração do material granulado dos sedimentos de decantação, na reciclagem da maioria dos mesmos na área de mistura (2) e na remoção dos sedimentos de decantação separados do material granulado.
