Análise da estação compacta de tratamento de esgoto no Bairro Novo em Delmiro Gouveia - AL

Abstract

The deficiency of the services of environmental sanitation is one of the characteristic problems of the urban centers, fact that directly influences in the indices of infant mortality. In Delmiro Gouveia, which receives works to adapt the sanitary sewage system, the compact sewage treatment station located in the Bairro Novo is deactivated. Its installation dates from September 2002. The dumping of raw sewage into water bodies is very harmful in the case of public health and the comfort of those who live near the place of eviction. The final flow rate was 410.7 m3 / day, lower than the nominal capacity of UASB reactors (Upflow Anaerobic Slugde Blanket), working together in parallel, which is 540 m3 / day. The BOD concentration in the station effluent was estimated at 105 mg / l, while the suspended solids concentration was 181.65 mg / l. It was possible to verify that the efficiency can be increased considerably with the post-treatment increment to the effluent of the UASB reactors.
