Remoção de matéria orgânica e nitrogênio de efluentes provenientes de abatedouros de bovinos por meio de reator aeróbio operando em bateladas sequenciais com adição de coagulante químico

The volume of liquid effluent generated in cattle slaughterhouses is quite high and cannot be released untreated in water bodies due to its high pollution load of predominantly organic origin. To minimize the environmental impacts of its industrial wastewater and meet the local environmental legislation, abattoirs shall make the treatment of these effluents. The present work aims to develop the study of a reactor by sequential batch pilot scale, in order to optimize their performance in treating wastewater from a cattle slaughterhouse. The treatment system used was developed and installed in the Laboratory of Wastewater Treatment, in Faculty of Science and Technology UNESP, Presidente Prudente campus. The procedure used followed the operation of sequential batch reactors, in which all processes and treatment operations occurring sequentially in a single unit, by establishing specific operating cycles, which comprise the following separated phases: aerobic reaction, anoxic reaction, sedimentation and emptying. Aiming to improve the quality of treatment was planned the addition of coagulant Poly Aluminum Chloride (PAC) in the reactor, by determining their optimal dosage by Jar-test trials. Were prepared four steps with specific operating cycles: step one or acclimatization (10 hour of aeration, one hour and 30 minutes of sedimentation and 30 minutes for exchanging the effluent); step 2 (6 hours of aeration or aerobic phase, 4 hours and 45 minutes of stirring or anoxic phase and 1 hour and 15 minutes for sedimentation and exchange effluent); step 3 (2 hours and 30 minutes of aeration, 8 hours and 15 minutes of stirring and 1 hour and 15 minutes for sedimentation and exchange) and step 4 (2 hours of aeration, 8 hours and 45 minutes of stirring and 1 hour and 15 minutes for sedimentation and exchange)...

Análise da flexibilidade e da postura em jovens atletas praticantes de futebol

there is evidence that sport can trigger the onset of postural patterns specific to each modality, regardless of the geopolitical aspects, social, cultural habits of everyday life and ethnicity. Since changes in flexibility are cited as possible precursors of decreased range of motion, thereby harming the mechanics of the lower limbs and gait. Objetcive: The objective of this study was to analyze changes in posture and flexibility in young soccer players. Methods: were assessed 51 youngsters, aged between 14 and 18 years, soccer players registered in the Municipal Presidente Prudente SP and categories of the base of Gremio of Presidente Prudente. Data were collected from the assessment by the postural software assessment, and flexibility tests the Bench, to jail and later by tests of muscle length to jail earlier proposed by Kendall et al , was also collected anthropometric data were later confronted with the results statistically. The results were organized into spreadsheets for computing, which later could be performed the statistical analysis. Values are expressed by means of central tendency and variability as well as medians and 95% confidence intervals. The comparison for each profile height and BMI was made by means of analysis of variance complemented by Tukey test. Were considered the statistical differences when P <0.05. Results: In the sample studied 64% of the subjects classified as normal posture, the same happened with 70.59% of the athletes for flexibility in relation to the center of gravity of the sample had 100% anterior displacement of the trunk and 86.28% with a deviation of center of gravity to the left, showing a tendency to some postural deviations for the group assessed. Conclusion: from the results we can conclude that there was significant relationship between the postural angle of the right leg and left angle of the pelvis with BMI and also ankle angle...

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

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...
