Resumo: | The main objective of this study was to evaluate the performance of the anaerobic co-digestion of different concentrations of industrial landfill leachate associated with crude residual glycerin, in a continuous anaerobic bioreactor with a fixed-structure bed (ABFSB) in the same process of anaerobic co-digestion. In this way, co-digestion tests were carried out in laboratory scale (400 mL of useful volume), batch operated in mesophilic conditions (30 ± 1 °C), with a 30-day incubation time in which five levels of (0, 1.5, 5, 8.5, and 10%) and five food/microorganism (F/M) levels (0.3, 0.5, 1, 0, 1.5, and 1.7), adopting experimental design of the Central Composite Rotational Design (CCRD). The results indicated a significant effect on the responses: methanogenic potential, removal of organic matter in terms of COD, accumulated production of CH4, and estimation of maximum production of CH4 using the modified Gompertz model, considering a confidence interval of 95% (p <0.05). From the results and with the desirability test it was verified that the ideal mixture was 95.13% of the industrial landfill leachate with 4.87% of the crude residual (v/v) residual glycerin with F/M ratio of 1.61 to optimize the process as a function of the response variables. From this recommended combination, with approximately 5% glycerin added to the leachate (v/v), the performance of ABFSB was evaluated in the co-digestion cited. The performance of the process was evaluated in three stages: biomass adaptation, gradual increase of organic loading rate (OLR) and reduction of alkaline supplementation. After the first 48-day period, the results were favorable to the application of the bioreactor in the evaluated anaerobic co-digestion, since the system presented stable conditions regarding the operational parameters with the addition of alkalinity with sodium bicarbonate (NaHCO3) and biomass adaptation. Thus, the second stage was started with application of increasing OLR (2, 3.5, 7.1 and 11.6 gCOD L-1 d-1). In the OLR of 7.1 gCOD L-1 d-1, the process reached the maximum methane flow rate (MFR) of 7.61 LNCH4 d-1, methane (MY) yield of 0.302 LNCH4 gCODrem-1 and volumetric methane production rate (VMPR) of 2.79 LNCH4 L-1 d-1, with total COD (ERCOD) and soluble COD removal efficiencies (ERsCOD) above 90%. Thus, the condition adopted in the third was OLR of 7.1 gCOD L-1 d-1, CODaffluent of 10.68 gO2 L-1 and hydraulic holding time of 35.2 h, aiming to optimize the quantity effectively required of NaHCO3. The minimum required concentration of alkalinity supplementation was of 0.28 gNaHCO3 gDQOaffluent-1. It is concluded that alkalinity supplementation was an important factor in the stability of the bioreactor. Finally, it is evidenced that the system is promising and that the results can serve as subsidy for industrial landfills to adopt this form of co-digestion, with biogas energy use. |

Foram realizados ensaios de codigestão em reatores, em escala de laboratório, operados em batelada em condições mesofílicas (30 ±1 °C), com tempo de incubação de 30 dias, quando foram testados cinco níveis de adição de glicerina ao lixiviado (v/v) (0; 1,5; 5; 8,5 e 10%) e cinco níveis de relação alimento/microrganismo (A/M) (0,3; 0,5; 1,0; 1,5 e 1,7), adotando-se planejamento experimental do tipo Delineamento Composto Central Rotacional (DCCR). Os resultados obtidos indicaram efeito significativo para as variáveis respostas: potencial metanogênico, remoção de matéria orgânica, em termos de DQO, produção acumulada de CH4 e a estimativa da produção máxima de CH4 utilizando o modelo de Gompertz modificado, considerando intervalo de confiança de 95% (p<0,05). A partir dos resultados e com o ensaio da desejabilidade foi verificado que a mistura ideal foi de 95,13% do lixiviado de aterro industrial com 4,87% da glicerina residual bruta (v/v) com relação A/M de 1,61 para otimização do processo em função das variáveis respostas. A partir desta combinação recomendada, com aproximadamente 5% de glicerina adicionada ao lixiviado (v/v), avaliou-se o desempenho do ABFSB na codigestão citada. O desempenho do processo foi avaliado em três etapas: adaptação da biomassa, aumento gradual da carga orgânica volumétrica (COV) e redução da suplementação alcalina. Na primeira etapa o sistema apresentou condições estáveis quanto aos parâmetros operacionais com a suplementação da alcalinidade com bicarbonato de sódio (NaHCO3) e adaptação da biomassa. Na segunda etapa com aplicação de COV crescentes (2; 3,5; 7,1 e 11,6 gDQO L-1 d-1). Na COV de 7,1 gDQO L-1 d-1, o processo atingiu os máximos valores de vazão de metano (MFR) de 7,61 LNCH4 d-1, rendimento de metano (MY) de 0,302 LNCH4 gDQOrem-1 e a produção volumétrica de metano (VMPR) de 2,79 LNCH4 L-1 d-1, com eficiências de remoção de DQO total (ERDQO) e DQO solúvel (ERDQOs) superiores a 90%. Na terceira etapa com o COV de 7,1 gDQO L-1 d-1, DQOafluente de 10,68 gO2 L-1 e TDH de 35,2 h, visando otimizar a quantidade efetivamente necessária de NaHCO3. A concentração mínima necessária da suplementação de alcalinidade foi de 0,28 gNaHCO3 gDQOafluente-1. Concluiu-se que a suplementação da alcalinidade foi um fator de importância na estabilidade do biorreator, ficando evidenciado que o sistema é promissor e que os resultados podem servir de subsídio para que aterros industriais adotem esta forma de codigestão, com aproveitamento energético do biogás.Submitted by Rosangela Silva (rosangela.silva3@unioeste.br) on 2018-05-30T14:15:49Z No. of bitstreams: 2 Thiago Morais de Castro.pdf: 2981699 bytes, checksum: 66cbb29086744ea891ed186377e4ec48 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2018-05-30T14:15:49Z (GMT).

description |
The main objective of this study was to evaluate the performance of the anaerobic co-digestion of different concentrations of industrial landfill leachate associated with crude residual glycerin, in a continuous anaerobic bioreactor with a fixed-structure bed (ABFSB) in the same process of anaerobic co-digestion. In this way, co-digestion tests were carried out in laboratory scale (400 mL of useful volume), batch operated in mesophilic conditions (30 ± 1 °C), with a 30-day incubation time in which five levels of (0, 1.5, 5, 8.5, and 10%) and five food/microorganism (F/M) levels (0.3, 0.5, 1, 0, 1.5, and 1.7), adopting experimental design of the Central Composite Rotational Design (CCRD). The results indicated a significant effect on the responses: methanogenic potential, removal of organic matter in terms of COD, accumulated production of CH4, and estimation of maximum production of CH4 using the modified Gompertz model, considering a confidence interval of 95% (p <0.05). From the results and with the desirability test it was verified that the ideal mixture was 95.13% of the industrial landfill leachate with 4.87% of the crude residual (v/v) residual glycerin with F/M ratio of 1.61 to optimize the process as a function of the response variables. From this recommended combination, with approximately 5% glycerin added to the leachate (v/v), the performance of ABFSB was evaluated in the co-digestion cited. The performance of the process was evaluated in three stages: biomass adaptation, gradual increase of organic loading rate (OLR) and reduction of alkaline supplementation. After the first 48-day period, the results were favorable to the application of the bioreactor in the evaluated anaerobic co-digestion, since the system presented stable conditions regarding the operational parameters with the addition of alkalinity with sodium bicarbonate (NaHCO3) and biomass adaptation. Thus, the second stage was started with application of increasing OLR (2, 3.5, 7.1 and 11.6 gCOD L-1 d-1). In the OLR of 7.1 gCOD L-1 d-1, the process reached the maximum methane flow rate (MFR) of 7.61 LNCH4 d-1, methane (MY) yield of 0.302 LNCH4 gCODrem-1 and volumetric methane production rate (VMPR) of 2.79 LNCH4 L-1 d-1, with total COD (ERCOD) and soluble COD removal efficiencies (ERsCOD) above 90%. Thus, the condition adopted in the third was OLR of 7.1 gCOD L-1 d-1, CODaffluent of 10.68 gO2 L-1 and hydraulic holding time of 35.2 h, aiming to optimize the quantity effectively required of NaHCO3. The minimum required concentration of alkalinity supplementation was of 0.28 gNaHCO3 gDQOaffluent-1. It is concluded that alkalinity supplementation was an important factor in the stability of the bioreactor. Finally, it is evidenced that the system is promising and that the results can serve as subsidy for industrial landfills to adopt this form of co-digestion, with biogas energy use. |
