    Avaliou-se o desempenho de um reator anaer贸bio de fluxo ascendente com manta de lodo (UASB) seguido de um filtro anaer贸bio, instalados em s茅rie, com volume total de 300 L e 190 L, respectivamente, no tratamento de 谩guas residu谩rias de suinocultura. As cargas org芒nicas volum茅tricas aplicadas no reator UASB foram de 12,4;15,5; 23,2 e 26,3 g DQOtotal (L d)-1. Para o p贸s-tratamento do efluente do sistema anaer贸bio em dois est谩gios utilizou-se um filtro biol贸gico percolador com volume total de 250 L. O meio suporte utilizado nos filtros anaer贸bio e biol贸gico percolador foi composto por an茅is de bambu. No sistema de tratamento anaer贸bio e de p贸s-tratamento foram observadas efici锚ncias m茅dias de remo莽茫o de demanda qu铆mica de oxig锚nio total (DQOtotal), s贸lidos suspensos totais (SST), nitrog锚nio total (NT), f贸sforo total (P-total), Cu e Zn de at茅 98, 99, 78, 84, 99 e 98%, respectivamente.<br>The performance of an upflow anaerobic sludge blanket (UASB) followed by the anaerobic filter, installed in series, was evaluated for the treatment of swine wastewater. The total volume of UASB and anaerobic filter were of 300 L and 190 L, respectively. The organic load rate applied on the reactor UASB were of 12.4, 15.5, 23.2 and 26.3 g total COD (L d)-1. For the post-treatment of effluent the anaerobic system was used a trickling filter with total volume of 250 L. The supports used in the anaerobic filter and trickling filter were composed by bamboo rings. The efficiencies of removal the chemical oxygen demand, total solids suspended, nitrogen, total phosphorus, Cu and Zn were of up to 98, 99, 78, 84, 99 and 98%, respectively, for the anaerobic and aerobic treatment system
