Resumo

O tratamento de águas residuárias em países em desenvolvimento é um problema de acesso e eficiência. Os sistemas individuais de tratamento de esgoto são importantes quando a rede de coleta não chega a toda a comunidade. A eficiência do tratamento deve ser avaliada ao considerar o projeto dos sistemas e a prevenção do impacto ambiental negativo. Os sistemas de tratamento de esgoto são frequentemente utilizados como tratamento final para o polimento de águas residuárias. Este trabalho propõe um tratamento de esgoto utilizando um sistema híbrido composto de fossa séptica, filtro anaeróbico e um sistema de zonas úmidas utilizando plantas como tratamento terciário. Foram coletadas amostras para avaliar a demanda bioquímica de oxigênio (DBO), demanda química de oxigênio (COD), turbidez, cor aparente, sólidos totais, fósforo total (TP) e nitrogênio. Em dois pontos analisados, a remoção de contaminantes foi resultado do conjunto de fossas sépticas com o filtro anaeróbico. A eficiência do sistema melhorou a qualidade do efluente final, mostrando como uma excelente alternativa aos países com falta de estruturas coletivas para o tratamento de esgoto doméstico.
