Resumo
This study aimed to evaluate the efficiency of the bamboo species Guadua angustifolia Kunth, Guadua chacoensis and Dendrocalamus giganteus Munro in the treatment of the Senador Canedo Industrial District Sewer Treatment effluent. It was analyzed diary effluent slides of 176.8, 212.2, 247.6 and 353.7 mm applied in individual 200 L drums filled with regional soil (oxisoil) and vegetated with bamboo. Drums without plants served as control. The effluent treated by the containers was analyzed for biochemical oxygen demand
(BOD), dissolved oxygen, chemical oxygen demand (COD), apparent color, pH, ammonium nitrogen, phosphates, turbidity, chlorides, hardness, electrical conductivity, total solids, dissolved total solids, volatile total solids, fixed total solids and coliforms, during a five month period. The results were analyzed by Statistical Analysis System Program (SAS)
through F test and Tukey-Kramer test (5% of probability). Treatment using bamboo were more efficient than control in removing BOD, COD, pH, dissolved oxygen, apparent color,
total solids, fixed solids, coliforms, chlorides, turbidity, electrical conductivity, phosphates and ammonium nitrogen. Among vegetated drums, bamboos of Guadua gender were more efficient in removing BOD, COD, coliforms and volatile solids than units with D. giganteus. Application rates had no significant influence on treatment efficiencies. It was also evaluated the bamboo species under field conditions, submitted to a diary effluent slide of 353.7 mm for a period of one year. Samples of groundwater were collected to verify some resultant contamination from the effluent application. It wasn t observed groundwater contamination by applying effluent at soil vegetated with bamboo.
