CONTRIBUIÇÃO QUÍMICA PARA O PLANO DE GERENCIAMENTO DE ÁGUAS RESIDUAIS DE SERVIÇOS DE SAÚDE

Abstract

In this study were analyzed the main lines of health care waste at the Hospital of the Federal University of Paraná (HC/UFPR), performing an inventory that aims from awareness, characterization, until a viable wastewater treatment proposal for the institution. In this context, were emphasized physical and chemical analyses parameters, inorganic species following the legislation, as well as some chemical analysis used as support for the investigation of the environmental standard of hospital wastewater. The UFPR Clinical Hospital has a health care waste management plan, which is focused on the issue of solid waste. Thus, there are no policies, procedures and specific supervision for managing wastewater, which causes the waste to be disposed directly in the sewage network. At work in question was the physicochemical characterization, inorganic species other relevant chemical species and toxicological analysis of four collection points. Depending on the physical and chemical parameters, phenols and monitored toxicological analysis, one realizes that the hospital sewage characteristics are different from domestic sewage, which in principle suggests the need for special treatment. In this work, the behavior of the wastewater points of HC/UFPR against three types of treatment. The tests performed by the method of activated carbon, Fenton and photoFenton process.
