Hello, can someone fix? The present study aimed to physico-chemical characterization and preliminary biological effluent generated by municipal hospital Marica, Rio de Janeiro, the channel that receives the effluent from the hospital, and the water body water channel receiver (Lagoa Araçatiba). We analyzed samples collected at the hospital, city canal and the receiving body. The results were compared with those recommended by the laws federal, state, the normative and regulatory environmental agency ANVISA. The values obtained for BOD, COD, nitrogen and orthophosphate exceed those determined by regulations and assessments indicate microbiological contamination by fecal coliform in the effluent from the hospital, in values that go beyond the acceptable. Considering the lack of sewage treatment in the municipal hospital, the high rate of contamination by pathogens, the constant release of drugs that may confer multidrug resistance to microorganisms and that the receiving body is used for recreation, there is a need for system installation wastewater treatment in the municipal hospital. The method is indicated for pre-treatment, treatment with anaerobic sludge blanket activated upflow and post-treatment to remove pathogens. It is noteworthy that the methodology should be consistent with the water demand, available land, generation per capita, economic viability and environmental sustainability, considering the ecological vulnerability of the recipient water body.
