Resumo: | The cassava starch industries generate daily a large volume of wastewater effluent that, stabilized in ponds, waste its biogas energy and pollute the atmosphere. To contribute with the reversion of this reality, this manipueira treatment research in one phase anaerobic horizontal pilot reactor with continuous feeding was developed. The reactor was implanted at a starch factory, Toledo, PR, which processes 160 ton cassava day-1 and originates 800 m3 of cassava wastewater. The biomass agitation was obtained by biogas recirculation, pumped by radial compressor, being the support medium set up with 15 x 4 cm bamboo pieces. The cassava wastewater, in natura, flowed by a sand and clay separating chamber, feeding the reactor with volume measured by an hydrometer. The experimental design was a completely randomized design, with the responses submitted to multivariate analysis and to statistical quality control through R 13.0 and Minitab 15.1.0.0 softwares, respectively. The average organic loadings in chemical oxygen demand (COD) were 0.556; 0.670; 0.678; 0.770 and 0.902 g L-1; and in volatile solids (VS) 0.659; 0.608; 0.570; 0.761 and 0.816 g L-1 at the hydraulic retention times (HRT) of 13.0; 11.5; 10.0; 7.0 and 7.0 days. The average reductions for COD, at the same order that the HRTs, were 88; 80; 88; 67 and 70% and for VS 76; 77; 65; 61 and 53%. The biogas productions relatively to COD consumed were 0.368; 0.795; 0.891; 0.907 and 0.626 Lg-1, relatively to VS consumed were 0.524; 0.930; 1.757; 0.952 and 0.981 Lg-1 and volumetrically 0.131; 0.330; 0.430; 0.374 and 0.377 L L-1 d-1, with an average methane content of 56%. The 10.0 days HRT was evaluated with an average temperature of 27.7 °C and the others with temperatures ranging from 21.2 to 23.5 °C. The agitation efficiency was proven as it increased the reactor s performance, in spite of a 2.3 °C average reduction at the temperature. The stability indicators pH and volatile acidity/total alkalinity (VA/TA) relation remained between 6.51 to 7.45 and 0.11 to 0.82, respectively. Although the relation VA/TA has presented risk values, the reactor remained stable, possibly due to the support medium presence |

Para contribuir com a reversão dessa realidade, desenvolveu-se esta pesquisa de tratamento de manipueira em reator anaeróbio horizontal piloto com alimentação contínua. O reator foi implantado numa fecularia, em Toledo PR, que processa 160 t de mandioca dia-1 e gera 800 m3 de manipueira. A agitação da biomassa foi realizada por recirculação de biogás bombeado por compressor radial e o meio suporte foi montado com peças de bambu de 15 x 4 cm. A manipueira, in natura, fluiu por uma caixa separadora de areia e argila e alimentou o reator com volume medido por hidrômetro. O delineamento experimental foi inteiramente casualizado, com respostas submetidas à análise multivariada que permitiram avaliar as correlações entre as variaveis e ao controle estatístico da qualidade através dos programas R 13.0 e Minitab 15.0, respectivamente. As cargas orgânicas médias em demanda química de oxigênio (DQO) aplicadas foram de 0,556; 0,670; 0,678; 0,770 e 0,902 g L-1 e em sólidos voláteis (SV) de 0,659; 0,608; 0,570; 0,761 e 0,816 g L-1 nos tempos de retenção hidráulica (TRH) de 13,0; 11,5; 10,0; 7,0 e 7,0 dias, respectivamente, sendo o último TRH com agitação. As reduções médias de DQO, na ordem de apresentação dos TRHs, foram de 88; 80; 88; 67 e 70% e de SV 76; 77; 65; 61 e 53%. As produções de biogás por DQOc foram de 0,368; 0,795; 0,891; 0,907 e 0,626 Lg-1, por SVc de 0,524; 0,930; 1,757; 0,952 e 0,981 Lg-1 e volumétrica de 0,131; 0,330; 0,430; 0,374 e 0,377 L L-1 d-1, com média de metano em 56%. O TRH de 10,0 dias foi avaliado com temperatura média mais elevada, de 27,7 °C, e os demais com temperatura variando entre 21,2 a 23,5 °C. A eficiência do agitador foi comprovada ao melhorar o desempenho do reator, apesar da redução média de 2,3 °C na temperatura. Os indicadores de estabilidade, pH e relação acidez volátil/alcalinidade total (AV/AT), mantiveram médias entre 6,51 a 7,45 e 0,11 a 0,82, respectivamente. Apesar da relação AV/AT ter apresentado valores de risco, o reator permaneceu estável, o que pode ser devido à presença do meio suporteMade available in DSpace on 2017-05-12T14:48:45Z (GMT).
