Tanque séptico seguido de filtro de areia para tratamento de esgoto doméstico / Septic tank followed by a sand filter to treat wastewater

Cruz, Luana Mattos de Oliveira, 1985- 23 August 2018 (has links)
Orientador: Adriano Luiz Tonetti / Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia Civil, Arquitetura e Urbanismo / Made available in DSpace on 2018-08-23T09:50:45Z (GMT). No. of bitstreams: 1 Cruz_LuanaMattosdeOliveira_D.pdf: 6934154 bytes, checksum: 61a0ccbf918fa03d5286b5be5d9bb7fc (MD5) Previous issue date: 2013 / Resumo: Nos países em desenvolvimento, estimativas indicam que 82% das residências rurais não têm acesso a serviços sanitários. A falta de esgotamento sanitário aumenta o risco de doenças de veiculação hídrica e compromete a sustentabilidade ambiental. Por esta situação, muitos estudos são conduzidos para serem avaliados tratamentos descentralizados que são mais indicados para estas áreas com residências dispersas. Entretanto, a maioria dos estudos são feitos em escala de bancada havendo a necessidade do desenvolvimento de trabalhos em escala real sob condições de campo. Frente ao exposto, o presente trabalho visou à construção de um sistema de tratamento de esgoto doméstico descentralizado em escala real composto por um tanque séptico seguido de filtro de areia e desinfetado. O objetivo foi avaliar a sua instalação, manutenção, operação e eficiência de tratamento em condições de campo, além de verificar as condições de desinfecção para reúso em vaso sanitário. Os resultados demonstram que esta associação operou de maneira eficiente e que necessita de manutenção a cada 2 meses. O efluente final tinha concentrações superiores ao limite máximo permitido pelas legislações vigentes em termos de nitrogênio amoniacal e fósforo, entretanto há grande potencial de reúso agrícola para este produto final. Em relação à adequação ao reúso em vaso sanitário, foi necessária a desinfecção durante 45 minutos com solução de hipoclorito de cálcio em concentração de 1,15 mgL-1. Deste modo, este estudo originou uma importante contribuição para o saneamento de comunidades isoladas / Abstract: In developing countries, estimates indicate that 82% of rural residences lack sanitation services which lead to an increase in the prevalence of water-borne diseases and hinders the community's environmental sustainability. Numerous studies have been done in order to evaluate the efficacy and feasibility of decentralized treatments which may be more indicated to these areas with diffuse households. However, the majority of these studies have been completed in laboratories or in pilot-scale programs, and full-scale field investigations are still lacking. Thus this investigation aimed to construct a decentralized wastewater treatment system in real scale, consisting of a septic tank, a sand filter and a disinfection essay. This study aimed to evaluate the installation, maintenance, operation and treatment efficiency of the water treatment system under field conditions, and also to define disinfection conditions required for the reuse of the effluent in the toilet. Results have shown that the implemented water treatment system was independently effective throughout a 2 - month period, after which point maintenance was requited. Nitrogen and phosphorus concentrations in final effluent were above the levels recommended by Brazilian standards; on the other hand, even so there is a great potential effluent for crops irrigation reusing. In order to disinfect the effluent for toilet use, it was necessary a sodium hypochlorite solution with 1,15mgL-1 concentration. In all, results indicated that the decentralized wastewater treatment system implemented in this study was nearly efficient with minimal engineering requirements. Therefore this research contributed for sanitation in rural areas / Doutorado / Saneamento e Ambiente / Doutora em Engenharia Civil
