Neste trabalho estudou-se o pós-tratamento de efluente de filtros anaeróbios operados com baixo tempo de detenção hidráulica (TDH) por meio do escoamento superficial no solo. Para isso, foram construídos quatro reatores com volume de 500 L preenchidos com anéis de bambu e uma rampa com 40,0 m de comprimento e declividade de 3,50%, coberta com grama Tifton 85 (Cynodon sp). Avaliou-se o tratamento do esgoto doméstico proveniente da cidade de Limeira (SP), operando os filtros anaeróbios com TDH de 3 horas e a aplicação do efluente no escoamento superficial com taxas de 0,10; 0,20; 0,30 e 0,40 m³.h-1.m-1. Nestas condições operacionais, o efluente gerado era adequado ao lançamento em corpos hídricos até a aplicação da taxa de 0,20 m³.h-1.m-1. Acima desse valor, houve um comprometimento de sua qualidade final em termos de DBO e concentração de fósforo. In this investigation the post-treatment of anaerobic filters operated with low hydraulic retention time (HRT) through overland flow system was studied. For that, it was built four reactors whose volume was 500 L, filled up with bamboos rings and a ramp with 40.0 m of length and inclination of 3.5%, covering with Tifton 85 (Cynodon sp) grass. It was evaluated the wastewater treatment from Limeira city (SP), operating anaerobic filters with 3 hour HRT and the effluent application in superficial drain of 0.10; 0.20; 0.30 e 0.40 m³.h-1.m-1 rates. In these operational conditions, the effluent was suitable to be discharged into receiving waters until the rate application of 0.20 m³.h-1.m-1. Over this value, there was a worse final quality in DBO and phosphorus concentration
