Remoção de N-amoniacal em baixas concentrações de oxigênio dissolvido a partir do efluente de frigorífico bovino

This work aimed to develop a biological system for removal of ammonia nitrogen operating at low concentrations of dissolved oxygen. Thus, a biological upflow vertical reactor was built, in which the affluent pass through the support media until the top. Sludge from an anaerobic stabilization pond of a slaughterhouse unit in the city of Presidente Prudente - SP was used as inoculum. Initially the system operated in batch and afterwards in a continuous flow with different HRT. For feeding the reactor, an initial phases was adopted a synthetic culture media, described by Martins (2007), in order to establish the ideal conditions for the development of Anammox bacteria and subsequently, submitted to the system a slugde effluent of slaughterhouse. The results showed significant removal efficiency of N-NH4+, especially in the phase without recirculation of culture media, with an average of 71% removal, with the proportion of removal of N-NH4 +:N-NO2- average 1: 1,69. For the period of operation with effluent from the slaughterhouse, were not obtained satisfactory results, without confirmation of the proliferation of Anammox bacteria in the system, due to the high presences of organic matter in the same confirmed by high concentrations of COD

Planejamento ambiental da bacia hidrográfica do córrego Embirí – UGRHI Pontal do Paranapanema – São Paulo: inventário e diagnóstico

This study aimed to contribute to the environmental planning of the watershed Embirí stream - UGRHI Pontal Paranapanema (belonging to the Paranapanema Management unit) in the cities of Presidente Prudente and Regente Feijó, São Paulo. This basin is located in the area of the Santo Anastácio river source, responsible for supplying water to about 30% of the population of Presidente Prudente. The methodological procedures based on Leal (1995) and Rodriguez et al. (2004), and the steps include inventory and diagnosis of the basin. We conducted extensive literature review, cartographic and documentary on the subject area of research, field work, preparation of thematic maps and summary chart of physical units and environmental use and land cover, participatory mapping of environmental risks, quality analysis of water. Most of the basin of the stream of twine had a high environmental fragility and the main problems found were lack of riparian vegetation, erosion, siltation of water bodies, irregular disposal of debris and the dumping of sewage. The results were summarized in the diagnosis and can identify the most important environmental impacts, environmental and spatial weaknesses of the legislation, and thus draw up proposals for action to the area that is substantially degraded

Cidade da dança

This work is the result of an exploratory analysis of the city of Presidente Prudente, based on the perception and understanding of the ambience of the city. Idea that permeates urban issues, architectural, artistic and environmental to be a project method. It assumes that the city is a mutant organism that dance and must be analysed before their incessant metamorphosis. Is studied, then the city as a tangle of events, trying to demonstrate that any changes to the design of the city can bring changes in the entire body

Tratamento de efluentes provenientes de abatedouro de bovinos por meio de reator enzimático seguido de reator aeróbio operado em bateladas sequenciais

Brazil has one of the largest cattle herds in the world, so the cattle slaughter is one of the most important economic activities in the Brazilian market. But this activity requires a high demand of water, resulting in serious problems about the correct disposal of wastewater generated in the process. This effluent has a high pollution load, becoming its receiving bodies (streams and rivers) unfit for various activities such as public water supply, recreation, fisheries. To minimize the environmental impacts of its industrial wastewater and fallow the local environmental legislation, refrigerators must make the treatment of these effluents. This study aimed to verify the efficiency of a enzymatic reactor, when occur hydrolysis of lipids present in the effluent industrial of an cattle slaughter industry. The treatment system used was composed of two separate reactors: one being the anaerobic fluidized bed reactor (AFBR), inoculated with immobilized enzymes on the matrix support, and the other by sequential batch reactor (SBR) inoculated with activated sludge. Whereas, the reactors have been developed and installed at the Wastewater Treatment Laboratory, Faculdade de Ciências e Tecnologia, UNESP, campus Presidente Prudente. The procedure operating occurred differently for each reactor: preparation and inoculation of enzyme granules, filling the reactor, hydrolysis, and AFBR emptying, filling, aerobic reaction, sedimentation, and emptying the SBR. We performed three experimental stages, with the first and second stage of the work were done reactor analyzes separately, and the third step of the analysis were made with the interconnected reactors...

Viva cidade: habitaçao de interesse social

As cidades brasileiras, ano a ano, vivem um crescente processo de urbanização, o qual nem sempre ocorre de uma maneira ordenada. Tal evento causou e tem causado um déficit de habitação para uma parte da população classificada como baixa renda e que se vê sem opções dignas de moradia. Portanto, este trabalho tem o objetivo de propor um projeto de Habitação de Interesse Social para essa classe mais pobre em uma área já consolidada do município. Trata-se da remoção de um cortiço com habitações insalubres, mas que está contida numa malha urbana central, com equipamentos públicos, servida de infra-estrutura e acesso a transporte público, ou seja, em uma área classificada como de inclusão social na cidade de Presidente Prudente – SP

Aplicação de coagulantes naturais no tratamento de lixiviado de resíduos urbanos

With the constant increase in the municipal solid waste (MSW) generation, mainly due to the high consumption patterns, it becomes difficult to manage correctly the solid waste and thus minimize their impact on the environment. One of the most problems of the large amount of waste generated is the liquid originated from physical, chemical and biological decomposition process of organic wastes, with dark color and bad smell, called leachate: it can reach the soil, polluting the groundwater and the surface water. Therefore, this study aimed to investigate the process of coagulation/flocculation/sedimentation applied in the treatment of the leachate generated in the not controlled landfill of Presidente Prudente, Sao Paulo...
