Повний текст джерелаThe production of renewable energy and fertilizer, through anaerobic biodegradation (AnBio) of waste from pig farming, presents itself as a strategic solution to minimize the negative effects associated with the large volume of manure generated in a small production space. However, further studies should be conducted to improve the understanding on the process and propose improvements. In this sense, this work was divided into three stages. In the first stage, a study was conducted to evaluate the changes that occur in organic matter and in organic and inorganic forms of nitrogen (N) and phosphorus (P) of the solid fraction of pig manure (PM) using anaerobic bench-top reactors as a function of seven hydraulic retention times (7, 14, 21, 28, 35, 42 and 49 days of biodegradation) and compared with the raw manure. In the second stage, we developed a study of anaerobic co-digestion, in a semi-continuous reactor, using the PM and the industrial waste of tomato processing (WTP) at different mixing ratios, to improve the performance of digestion and establish the best ratio of the two substrates for the production of biogas and methane. The following proportions were used (% PM + % WTP): 10% + 90%, 20% + 80%, 30% + 70%, 50% + 50% and 40% + 60%. In the third stage, there was an innovative study to recover the N present in the digestate generated after AnBio, using semipermeable membranes made of expanded polytetrafluoroethylene (PTFE) submerged in the material. This system consists of forcing the volatilization of N present in the digestate in the form of NH3 and then recover it in an acid solution of 1N H2SO4 flowing through the inside of the PTFE membrane. The N is recovered as the ammonium ion (NH4+), with potential for being used as fertilizer. Besides the digestate, raw pig manure (RPM) was used to compare the N recovery potential of both materials. The accumulation of the NH4+ formed was determined at nine sampling times (0, 7, 20, 30, 44, 54, 70, 79 and 93 hours). Based on the results obtained in the first stage, it was concluded that, during the digestion process, the organic matter of higher lability, represented by the carbon of the fulvic acid fraction and carbon oxidizable with 2.5 mL of H2SO4, was partially consumed, promoting the accumulation of recalcitrant organic matter at the end of the process. The contents of organic N and NH4+ reduced respectively by 45.2% and 54.2%, compared with their initial contents in the RPM, probably due to loss by volatilization. The P content reduced by 41.25% in relation to the initial content, due to the chemical precipitation of the inorganic fraction extractable in water with metallic cations within the reactor. In the case of co-digestion, increasing PM proportion to up to 30% of the feed mixture led to the maximum daily production of biogas (175 L) and the largest proportion of methane (60%). Amounts above 30% of manure in the mixture reduced biogas and methane production due to the increase of free NH3 concentration (272 mg L-1), which is toxic to most methanogens. As regards the recovery of N using PTFE membranes, it was observed that the recovery efficiency of the digestate was 12% higher compared with that observed in the RPM. Quantitatively, 4555 mg NH4+ could be recovered from the digestate in 93 hours of experiment, which can be used later as a source of N to agricultural crops.
A produÃÃo de energia renovÃvel e fertilizante, atravÃs da biodegradaÃÃo anaerÃbia (BioAn) dos dejetos da suinocultura, apresenta-se como uma soluÃÃo estratÃgica para minimizar os efeitos negativos associados ao grande volume de dejeto gerado em um reduzido espaÃo de produÃÃo. Contudo, mais estudos devem ser realizados para melhorar o entendimento do processo e propor melhorias. Nesse sentido, realizou-se este trabalho que foi dividido em trÃs etapas. Na primeira, foi realizado um estudo com o objetivo de avaliar as mudanÃas que ocorrem na matÃria orgÃnica e nas formas orgÃnicas e inorgÃnicas de nitrogÃnio (N) e fÃsforo (P) da fraÃÃo sÃlida do dejeto suÃno (DS), utilizando reatores anaerÃbios de bancada, em funÃÃo de sete tempos de retenÃÃo hidrÃulica (7, 14, 21, 28, 35, 42 e 49 dias de biodegradaÃÃo) e comparados com o dejeto nÃo degradado. Na segunda etapa, desenvolveu-se um estudo de co-digestÃo anaerÃbia, em um reator semicontÃnuo, utilizando o DS e o resÃduo da indÃstria do processamento do tomate (RPT) em diferentes proporÃÃes de mistura, visando melhorar o desempenho da biodegradaÃÃo e estabelecer a melhor proporÃÃo dos dois substratos para a produÃÃo de biogÃs e metano. Utilizaram-se as seguintes proporÃÃes (% de DS + % de RPT): 10% + 90%, 20% + 80%, 30% + 70%, 50% + 50% e 60% + 40%. Na terceira etapa, realizou-se um estudo inovador visando recuperar o N presente no digestato gerado apÃs a biodegradaÃÃo, utilizando membranas semipermeÃveis de politetrafluoroetileno expandido (PTFE) submersas no material. Esse sistema consistiu em forÃar a volatilizaÃÃo do N presente no digestato na forma de NH3 e, posteriormente, recuperÃ-lo em uma soluÃÃo Ãcida de H2SO4 1N que circulava pelo interior da membrana de PTFE. O N foi recuperado na forma do Ãon amÃnio (NH4+), com potencial para ser utilizado como fertilizante. Utilizou-se alÃm do digestato, DS nÃo degradado, para comparaÃÃo do potencial de recuperaÃÃo de N dos dois materiais. A determinaÃÃo do acÃmulo de NH4+ formado foi realizada em nove tempos de amostragem (0, 7, 20, 30, 44, 54, 70, 79 e 93 horas). Com base nos resultados obtidos na etapa 1, concluiu-se que durante a biodegradaÃÃo, a matÃria orgÃnica de maior labilidade, representada pelo carbono da fraÃÃo Ãcido fÃlvico e carbono oxidÃvel com 2,5 mL de H2SO4, foi parcialmente consumida, promovendo o acÃmulo de matÃria orgÃnica recalcitrante no final do processo. Os conteÃdos de N orgÃnico e NH4+ reduziram respectivamente, 45,2% e 54,2% em relaÃÃo aos seus conteÃdos iniciais no dejeto nÃo degradado, devido, provavelmente, a perda por volatilizaÃÃo. O conteÃdo de P reduziu 41,25% em relaÃÃo ao seu conteÃdo inicial, devido à precipitaÃÃo quÃmica da fraÃÃo inorgÃnica extraÃvel em Ãgua com cÃtions metÃlicos no interior do reator. No caso da co-digestÃo, o aumento da proporÃÃo do DS atà o limite de 30% da mistura de alimentaÃÃo, proporcionou a mÃxima produÃÃo diÃria de biogÃs (175 L) e a maior proporÃÃo de metano (60%). Quantidades superiores a 30% de dejeto na mistura, reduziram a produÃÃo de biogÃs e metano devido ao aumento da concentraÃÃo de NH3 Livre (272 mg L-1) tÃxico a maioria dos microrganismos metanogÃnicos. No que se refere à recuperaÃÃo do N utilizando as membranas de PTFE, observou-se que a eficiÃncia de recuperaÃÃo no digestato foi superior em 12% em relaÃÃo ao observado no dejeto nÃo degradado. Em termos quantitativos, conseguiu-se recuperar 4555 mg de NH4+ proveniente do digestato durante 93 horas de experimento que poderÃ, posteriormente, ser utilizado como fonte de N para as culturas agrÃcolas.
