Dimensionamento de biorremediação para tratamento de esgotos domésticos aplicado às zonas rurais

Abstract

Basic sanitation presents precarious conditions in much of the Brazilian territory, with na index of 50.3% of collected sewage, directly influencing public health. In rural areas, the situation is more contingent, with high rates of waterborne diseases, due to the low social standard and lack of treatment of domestic sewage. Developing sanitation in rural áreas requires understanding the characteristics of the location under study, above all, to implemente a sustainable, effective and economically viable treatment technology. An alternative is plant bioremediation – a green cesspool that provides efficient treatment of domestic effluents in rural and urban areas, promoting quality of life, health and enabling the planting of fruit species that help in the treatment process. Therefore, the present study is about the dimensioning of a plant bioremediation system – green cesspool for the Peba village, located in the rural area of Delmiro Gouveia – Alagoas, serving 186 inhabitants and projected to last for 20 years. The population projection met the main calculation methods recommended for projects and the system was dimensioned according to NBR 7229/93.
